A snip, a splice : Power of rDNA Technology

Deoxyribonucleic acid (DNA), the blueprint of life, holds the secrets to the intricate workings of every living organism. But what if we could manipulate this blueprint, adding, removing, or tweaking its code? This revolutionary concept forms the core of recombinant DNA (rDNA) technology, a powerful tool that has transformed biology and medicine.

The story starts in the early 1970s with two brilliant scientists; Stanley Cohen at Stanford University and Herbert Boyer at the University of California, San Francisco. Cohen, a microbiologist, had been studying plasmids – small circular DNA molecules found in bacteria. Boyer, a biochemist, was an expert on restriction enzymes – molecular scissors that could cut DNA at specific sequences. Their collaboration proved groundbreaking. They envisioned combining these tools to create the first ever recombinant DNA molecule. Cohen provided the plasmids, which would act as vectors to carry foreign DNA into host cells. Boyer, on the other hand, used restriction enzymes to cut both the plasmid and the desired foreign DNA, allowing them to be pieced together. Through meticulous experimentation, they successfully created the first recombinant DNA molecule, forever altering the course of biology.

Cohen and Boyer's work wouldn't have been possible without the earlier discoveries of restriction enzymes. These "molecular scissors" were independently identified by three separate research groups in the 1960s. Werner Arber in Switzerland, along with Hamilton Smith and Daniel Nathans in the US, unraveled the role of restriction enzymes in bacterial defense mechanisms. These enzymes helped bacteria defend against invading viruses by cutting up their foreign DNA. Recognizing the potential of these "genetic scalpels," the groundwork was laid for their application in rDNA technology.

Here's a simplified breakdown of the rDNA process:

Isolation of DNA: The journey starts with isolating DNA from a donor organism.

Cleavage with Restriction Enzymes: Specific enzymes cut the DNA at defined sequences.

Selection of Vector: A carrier molecule (often a plasmid) is chosen to transport the recombinant DNA.

Ligation: The DNA fragments and vector are stitched together using DNA ligase, an enzyme.

Transformation: The recombinant DNA enters a host cell (usually bacteria or yeast).

Selection and Expression: The transformed cells are selected, and the gene of interest is expressed, leading to the desired protein production.

Since its inception, rDNA technology has played a pivotal role in several groundbreaking advancements. Let's take a whirlwind tour through some of the most significant moments in R-DNA history:

1978: Birth of Insulin on the Factory Floor: Scientists achieved a feat of genetic engineering by using R-DNA to produce human insulin in bacteria. This marked a turning point for diabetics, offering a readily available and more consistent source of this life-saving hormone.

1980s: Gene Wars and the Rise of GMOs: The 1980s saw the development of genetically modified organisms (GMOs). Plants were engineered with genes for insect resistance or herbicide tolerance, sparking debates about the safety and ethics of this technology. R-DNA research continues to be at the forefront of discussions regarding genetically modified foods.

1990s: The Human Genome Project Sets Sail: This ambitious international project aimed to sequence the entire human genome. R-DNA techniques played a crucial role in deciphering the 3 billion letters of our genetic code, opening doors for personalized medicine and a deeper understanding of human health and disease.

2000s: Gene Therapy Takes Center Stage: The first successful gene therapy trials for inherited diseases like severe combined immunodeficiency (SCID) took place. R-DNA technology offered a glimmer of hope for treating genetic disorders by introducing healthy genes to replace defective ones.

2010s and Beyond: CRISPR Takes Over: The emergence of CRISPR-Cas9, a revolutionary gene editing tool based on R-DNA principles, has ushered in a new era of genetic manipulation. With unprecedented precision, scientists can now edit genes in various organisms, holding immense potential for gene therapy, crop improvement, and even the eradication of diseases.

But with great power comes great responsibility, and R-DNA raises a host of ethical concerns.Tinkering with the building blocks of life carries the risk of unintended consequences. Engineered genes could escape and disrupt ecosystems, or modified organisms could have unforeseen health effects. The ability to edit human genes opens the door to designer babies, raising questions about social equity and the potential misuse of the technology for eugenics.

Who Controls the Tools? Access to R-DNA technology could be restricted to wealthy nations or corporations, exacerbating existing inequalities. Biosecurity is also a concern, as the technology could be misused for bioterrorism. Creating entirely new organisms forces us to confront what it means to be "natural." Should we modify plants and animals for human benefit, or preserve their original forms? R-DNA technology is a powerful tool, and we must have open discussions about its ethical implications. Scientists, policymakers, and the public all need to be involved in shaping the future of this technology. As we move forward, open dialogue and collaboration between scientists, policymakers, and the public are crucial to ensure the safe and ethical application of this powerful technology.

The journey of rDNA technology is a testament to human ingenuity and its potential to reshape our world. From decoding the secrets of life to creating solutions for healthcare, agriculture, and beyond, rDNA technology continues to evolve, promising a future filled with exciting possibilities.

Melissa Choi named director of MIT Lincoln Laboratory

New Post has been published on https://thedigitalinsider.com/melissa-choi-named-director-of-mit-lincoln-laboratory/

Melissa Choi named director of MIT Lincoln Laboratory

Melissa Choi has been named the next director of MIT Lincoln Laboratory, effective July 1. Currently assistant director of the laboratory, Choi succeeds Eric Evans, who will step down on June 30 after 18 years as director.

Sharing the news in a letter to MIT faculty and staff today, Vice President for Research Ian Waitz noted Choi’s 25-year career of “outstanding technical and advisory leadership,” both at MIT and in service to the defense community.

“Melissa has a marvelous technical breadth as well as excellent leadership and management skills, and she has presented a compelling strategic vision for the Laboratory,” Waitz wrote. “She is a thoughtful, intuitive leader who prioritizes communication, collaboration, mentoring, and professional development as foundations for an organizational culture that advances her vision for Lab-wide excellence in service to the nation.”

Choi’s appointment marks a new chapter in Lincoln Laboratory’s storied history working to keep the nation safe and secure. As a federally funded research and development center operated by MIT for the Department of Defense, the laboratory has provided the government an independent perspective on critical science and technology issues of national interest for more than 70 years. Distinctive among national R&D labs, the laboratory specializes in both long-term system development and rapid demonstration of operational prototypes, to protect and defend the nation against advanced threats. In tandem with its role in developing technology for national security, the laboratory’s integral relationship with the MIT campus community enables impactful partnerships on fundamental research, teaching, and workforce development in critical science and technology areas.

“In a time of great global instability and fast-evolving threats, the mission of Lincoln Laboratory has never been more important to the nation,” says MIT President Sally Kornbluth. “It is also vital that the laboratory apply government-funded, cutting-edge technologies to solve critical problems in fields from space exploration to climate change. With her depth and breadth of experience, keen vision, and straightforward style, Melissa Choi has earned enormous trust and respect across the Lincoln and MIT communities. As Eric Evans steps down, we could not ask for a finer successor.”

Choi has served as assistant director of Lincoln Laboratory since 2019, with oversight of five of the Lab’s nine technical divisions: Biotechnology and Human Systems, Homeland Protection and Air Traffic Control, Cyber Security and Information Sciences, Communication Systems, and ISR and Tactical Systems. Engaging deeply with the needs of the broader defense community, Choi served for six years on the Air Force Scientific Advisory Board, with a term as vice chair, and was appointed to the DoD’s Threat Reduction Advisory Committee. She is currently a member of the national Defense Science Board’s Permanent Subcommittee on Threat Reduction.

Having dedicated her entire career to Lincoln Laboratory, Choi says her long tenure reflects a commitment to the lab’s work and community.

“Through my career, I have been fortunate to have had incredibly innovative and motivated people to collaborate with as we solve critical national security challenges,” Choi says. “Continuing to work with such a strong, laboratory-wide team as director is one of the most exciting aspects of the job for me.”

Success through collaboration

Choi came to Lincoln Laboratory as a technical staff member in 1999, with a doctoral degree in applied mathematics. As she progressed to lead research teams, including the Systems and Analysis Group and then the Active Optical Systems Group, Choi learned the value of pooling expertise from researchers across the laboratory.

“I was able to shift between a lot of different projects very early on in my career, from radar systems to sensor networks. Because I wasn’t an expert at the time in any one of those fields, I learned to reach out to the many different experts at the laboratory,” Choi says.

Choi maintained that mindset through all of her roles at the laboratory, including as head of the Homeland Protection and Air Traffic Control Division, which she led from 2014 and 2019. In that role, she helped bring together diverse technology and human systems expertise to establish the Humanitarian Assistance and Disaster Relief Group. Among other achievements, the group provided support to FEMA and other emergency response agencies after the 2017 hurricane season caused unprecedented flooding and destruction across swaths of Texas, Florida, the Caribbean, and Puerto Rico.

“We were able to rapidly prototype and field multiple technologies to help with the recovery efforts,” Choi says. “It was an amazing example of how we can apply our national security focus to other critical national problems.”

Outside of her technical and advisory achievements, Choi has made an impact at Lincoln Laboratory through her commitments to an inclusive workplace. In 2020, she co-led the study “Preventing Discrimination and Harassment and Promoting an Inclusive Culture at MIT Lincoln Laboratory.” The work was part of a longstanding commitment to supporting colleagues in the workplace through extensive mentoring and participation in employee resource groups.

“I have felt a sense of belonging at the laboratory since the minute I came here, and I’ve had the benefit of support from leaders, mentors, and advocates since then. Improving support systems is very important to me,” says Choi, who will be the first woman to lead Lincoln Laboratory. “Everyone should be able to feel that they belong and can thrive.”

When the Covid-19 pandemic hit, Choi helped the laboratory navigate the disruptions — with its operations deemed essential — which she says taught her a lot about leading through adversity.

“We solve hard problems at the laboratory all the time, but to get thrown into a problem that we had never seen before was a learning experience,” Choi says. “We saw the entire lab come together, from leadership to each of the divisions and departments.”

That synergy has also helped Choi form strategic partnerships within and outside of the laboratory to enhance its mission. Drawing on her knowledge of the laboratory’s capabilities and its history of developing impactful systems for NASA and NOAA, Choi recently led the formation of a new Civil Space Systems and Technology Office.

“We were seeing this convergence between Department of Defense and civilian space initiatives, as going to the Moon, Mars, and the cislunar area [between the earth and moon] has become a big emphasis for the entire country generally,” Choi explains. “It seemed like a good time for us to pull those two sides together and grow our NASA portfolio. It gives us a great opportunity to collaborate with MIT centrally, and it ties in with our other strategic directions.”

Building on success

Choi believes her trajectory through the technical ranks of Lincoln Laboratory will help her lead it now.

“That experience gives me a view into what it’s like at multiple levels of the laboratory,” Choi says. “I’ve seen what’s worked and what hasn’t worked, and I’ve learned from different perspectives and leadership styles. Strong leaders are crucial, but it’s important to recognize that the bulk of the work gets done by the technical, support, and administrative employees across our divisions, departments, and offices. Remembering being an early staff member helps you understand how hard and exciting the work is, and also how critical those contributions are for our mission.”

Choi says she is also looking forward to expanding the laboratory’s collaboration with MIT’s main campus.

“So many areas, from AI to climate to space, have opportunity for us to come together,” Choi says. “We also have some great models of progress, like the Beaver Works Center or the Department of the Air Force – MIT Artificial Intelligence Accelerator program, that we can build from. Everyone here is very excited about doing that, and it will absolutely be a priority for me.”

Ultimately, Choi plans to lead Lincoln Laboratory using the approach that’s proven successful throughout her career.

“I believe very much that I should not be the smartest person in the room, and I rely on the smart people working with me,” Choi says. “I’m part of a team and I work with a team to lead. That has always been my style: Set a vision and goals, and empower and support the people I work with to make decisions and build on that strategy.”

ELISA: A Powerful Tool for Detecting the Invisible

ELISA, or Enzyme-Linked Immunosorbent Assay, has become a cornerstone of medical diagnostics and biological research. This versatile technique allows scientists to detect and quantify minute amounts of target molecules, such as proteins, antibodies, and even viruses, with remarkable accuracy. In this blog, we'll delve into the world of ELISA, exploring its various types, its applications, and the exciting future directions this technology holds.

At its core, ELISA relies on the exquisite specificity of antibodies. Antibodies are highly specialized proteins produced by the immune system in response to foreign invaders. Each antibody can bind to a unique structure, called an antigen, on a specific molecule. In an ELISA, scientists leverage this binding property to create a sensitive detection system.

The 1960s witnessed a surge in interest in immunoassays, techniques that utilize the specificity of antibodies to detect target molecules. One such technique, radioimmunoassay (RIA), developed by Rosalyn Yalow and Solomon Berson, revolutionized medical diagnostics. RIA used radioactively labeled antibodies to detect antigens, offering high sensitivity. However, concerns regarding the safety of radioactive materials fueled the search for a safer alternative. The year 1971 marked a turning point. Independently, Eva Engvall and Peter Perlmann published their work on a novel technique – the enzyme-linked immunosorbent assay (ELISA). ELISA replaced radioactive labels with enzymes, eliminating the safety concerns associated with RIA. Like RIA, ELISA harnessed the specific binding between antibodies and antigens. However, it employed enzymes that could generate a detectable signal, such as a color change, upon interacting with a substrate. This innovation paved the way for a safer and more user-friendly diagnostic tool.

The basic ELISA protocol involves immobilizing the target antigen on a solid surface like a plate well. Then, a sample containing the molecule of interest (e.g., a suspected virus) is introduced. If the target molecule is present, it will bind to the immobilized antigen. Next, an antibody specific to the target molecule, linked to an enzyme, is introduced. This "detection antibody" binds to the target molecule already attached to the antigen. Finally, a substrate specific to the enzyme is added. This antigen-antibody binding is visualized using an enzyme linked to a reporter molecule. When the enzyme encounters its substrate, a detectable signal is produced, such as a color change or luminescence. The intensity of this signal is directly proportional to the amount of antigen present in the sample, allowing for quantification. The beauty of ELISA lies in its adaptability. Several variations exist, each tailored for specific detection needs.

The Four Main ELISA Formats are:

Direct ELISA: Simplicity at its finest. In this format, the antigen is directly coated onto the ELISA plate. A labeled antibody specific to the antigen is then introduced, binding directly to its target. After washing away unbound molecules, the enzyme linked to the antibody generates a signal upon addition of the substrate. Direct ELISA offers a rapid and straightforward approach, but sensitivity can be lower compared to other formats due to the lack of amplification.

Indirect ELISA: Unveiling the Power of Amplification. Similar to the direct ELISA, the antigen is first coated onto the plate. However, instead of a labeled primary antibody, an unlabeled one specific to the antigen is used. This is followed by the introduction of a labeled secondary antibody that recognizes the species (e.g., mouse, rabbit) of the primary antibody. This two-step approach acts as an amplification strategy, significantly enhancing the signal compared to the direct ELISA. However, the presence of an extra incubation step and the potential for cross-reactivity with the secondary antibody add complexity.

Sandwich ELISA: Capturing the Antigen Between Two Antibodies. Here, the capture antibody, specific for one region of the antigen, is pre-coated onto the ELISA plate. The sample containing the antigen is then introduced, allowing it to be "sandwiched" between the capture antibody and a detection antibody specific for a different region of the same antigen. A labeled secondary antibody or a labeled detection antibody itself can then be used to generate the signal. Sandwich ELISA boasts high sensitivity due to the double-antibody recognition and is often the preferred format for quantifying analytes.

Competitive ELISA: A Race for Binding Sites. In this format, the antigen competes with a labeled antigen (usually a known amount) for binding sites on a capture antibody pre-coated onto the plate. The more antigen present in the sample, the less labeled antigen can bind to the capture antibody. Following a washing step, the amount of bound labeled antigen is measured, providing an inverse relationship between the signal and the concentration of antigen in the sample. Competitive ELISA is particularly useful for studying small molecules that may be difficult to directly conjugate to an enzyme.

ELISA's Reach: From Diagnostics to Research. The applications of ELISA are as vast as they are impressive. Let's delve into some key areas where ELISA plays a vital role:

Unveiling the Mysteries of Disease: Diagnostics: ELISA is a cornerstone of diagnosing infectious diseases like HIV, Hepatitis, and Lyme disease. It detects antibodies produced by the body in response to the invading pathogen, providing valuable information for early detection and treatment. Monitoring Autoimmune Diseases: ELISA helps monitor autoimmune diseases like rheumatoid arthritis and lupus by measuring specific antibodies associated with these conditions. Cancer Screening: Certain cancers can be detected by identifying tumor markers, proteins elevated in the blood of cancer patients. ELISA assays are being developed to detect these markers for early cancer screening.

Safeguarding Food Quality: Allergen Detection: Food allergies can be life-threatening. ELISA ensures food safety by enabling the detection of allergens like peanuts, gluten, and milk in food products, protecting consumers with allergies. Monitoring Foodborne Pathogens: ELISA can identify harmful bacteria, viruses, and toxins in food, preventing outbreaks of foodborne illnesses.

Environmental Monitoring: Pollutant Detection: ELISA can detect pollutants like pesticides and herbicides in water and soil samples, contributing to environmental protection efforts. Microbial Analysis: This technique can be used to identify and quantify specific microbes in environmental samples, providing insights into ecosystem health.

Research and Development: ELISA plays a crucial role in various research fields: Drug Discovery: It helps researchers assess the effectiveness of new drugs by measuring drug-target interactions and monitoring drug levels in the body. Vaccine Development: ELISA is instrumental in developing vaccines by evaluating immune responses to vaccine candidates. Basic Research: Scientists use ELISA to study various biological processes by detecting and quantifying specific molecules involved in these processes.

Despite its established role, ELISA is evolving alongside technological advancements. New multiplex platforms allow for the simultaneous detection of various targets in a single sample, boosting efficiency in biomarker discovery and disease analysis. Automation streamlines workflows minimizes errors, and increases throughput, making high-throughput screening feasible in drug development and clinical settings. Miniaturization and portable devices enable rapid on-site diagnostics, providing healthcare professionals with real-time data for quicker interventions. Additionally, ongoing research is improving assay sensitivity, reducing background noise, and expanding detection limits, allowing for the identification of trace analytes and early disease biomarkers with greater accuracy than ever before. Integration of ELISA with emerging technologies such as microfluidics, nanotechnology, and artificial intelligence holds promise for enhancing assay performance, scalability, and data analysis capabilities.

These advancements hold promise for even wider applications of ELISA in the future. ELISA has revolutionized our ability to detect and quantify biological molecules. Its versatility, accuracy, and adaptability make it an invaluable tool across various scientific disciplines. As research continues to refine and innovate ELISA techniques, we can expect even more exciting possibilities to emerge in the years to come. ELISA's future is bright, promising to play a pivotal role in unraveling the mysteries of the biological world and improving human health.

Vague Professor at Penn Medicine, and approved by the Food and Drug Administration (FDA) in 2017, CAR T cell therapy mobilizes patients’ own immune systems to fight lymphoma and leukemia, among other cancers.

Using activating lipid nanoparticles (aLNPs) to create CAR T cells requires fewer steps and less time.

However, the process for manufacturing CAR T cells itself is time-consuming and costly, requiring multiple steps over days. The state-of-the-art involves extracting patients’ T cells, then activating them with tiny magnetic beads, before giving the T cells genetic instructions to make chimeric antigen receptors (CARs), the specialized receptors that help T cells eliminate cancer cells.

Now, Penn Engineers have developed a novel method for manufacturing CAR T cells, one that takes just 24 hours and requires only one step. This method uses lipid nanoparticles (LNPs), the potent delivery vehicles that played a critical role in the Moderna and Pfizer-BioNTech COVID-19 vaccines.

In a new paper in Advanced Materials, Michael J. Mitchell, Associate Professor in Bioengineering, describes the creation of “activating lipid nanoparticles” (aLNPs), which can activate T cells and deliver the genetic instructions for CARs in a single step, greatly simplifying  the CAR T cell manufacturing process. “We wanted to combine these two extremely promising areas of research,” says Ann Metzloff, a doctoral student and NSF Graduate Research Fellow in the Mitchell lab and the paper’s lead author. “How could we apply lipid nanoparticles to CAR T cell therapy?”

In some ways, T cells function like a military reserve unit: in times of health, they remain inactive, but when they detect pathogens, they mobilize, rapidly expanding their numbers before turning to face the threat. Cancer poses a unique challenge to this defense strategy. Since cancer cells are the body’s own, T cells don’t automatically treat cancer as dangerous, hence the need to first “activate” T cells and deliver cancer-detecting CARs in CAR T cell therapy.

Until now, the most efficient means of activating T cells has been to extract them from a patient’s bloodstream and then mix those cells with magnetic beads attached to specific antibodies — molecules that provoke an immune response. “The beads are expensive,” says Metzloff. “They also need to be removed with a magnet before you can clinically administer the T cells. However, in doing so, you actually lose a lot of the T cells, too.”

Made primarily of lipids, the same water-repellent molecules that constitute household cooking fats like butter and olive oil, lipid nanoparticles have proven tremendously effective at delivering delicate molecular payloads. Their capsule-like shape can enclose and protect mRNA, which provides instructions for cells to manufacture proteins. Due to the widespread use of the COVID-19 vaccines, says Metzloff, “The safety and efficacy of lipid nanoparticles has been shown in billions of people around the world.”

To incorporate LNPs into the production of CAR T cells, Metzloff and Mitchell wondered if it might be possible to attach the activating antibodies used on the magnetic beads directly to the surface of the LNPs. Employing LNPs this way, they thought, might make it possible to eliminate the need for activating beads in the production process altogether. “This is novel,” says Metzloff, “because we’re using lipid nanoparticles not just to deliver mRNA encoding CARs, but also to initiate an advantageous activation state.”

Over the course of two years, Metzloff carefully optimized the design of the aLNPs. One of the primary challenges was to find the right ratio of one antibody to another. “There were a lot of choices to make,” Metzloff recalls, “since this hadn’t been done before.”

By attaching the antibodies directly to LNPs, the researchers were able to reduce the number of steps involved in the process of manufacturing CAR T cells from three to one, and to halve the time required, from 48 hours to just 24 hours. “This will hopefully have a transformative effect on the process for manufacturing CAR T cells,” says Mitchell. “It currently takes so much time to make them, and thus they are not accessible to many patients around the world who need them.”

CAR T cells manufactured using aLNPs have yet to be tested in humans, but in mouse models, CAR T cells created using the process described in the paper had a significant effect on leukemia, reducing the size of tumors, thereby demonstrating the feasibility of the technology.

Metzloff also sees additional potential for aLNPs. “I think aLNPs could be explored more broadly as a platform to deliver other cargoes to T cells,” she says. “We demonstrated in this paper one specific clinical application, but lipid nanoparticles can be used to encapsulate lots of different things: proteins, different types of mRNA. The aLNPs have broad potential utility for T cell cancer therapy as a whole, beyond this one mRNA CAR T cell application that we’ve shown here.”
