Macrophages (abbreviated Mφ, MΦ or MP) are a type of white blood cell of the innate immune system that engulf and digest pathogens, such as cancer cells, microbes, cellular debris, and foreign substances, which do not have proteins that are specific to healthy body cells on their surface. This process is called phagocytosis, which acts to defend the host against infection and injury. Macrophages are found in essentially all tissues, where they patrol for potential pathogens by amoeboid movement. They take various forms (with various names) throughout the body (e.g., histiocytes, Kupffer cells, alveolar macrophages, microglia, and others), but all are part of the mononuclear phagocyte system. Besides phagocytosis, they play a critical role in nonspecific defense (innate immunity) and also help initiate specific defense mechanisms (adaptive immunity) by recruiting other immune cells such as lymphocytes.
A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. If the cell grows uncontrollably, it will result in cancer. When a tumor suppressor gene is mutated, it results in a loss or reduction in its function. In combination with other genetic mutations, this could allow the cell to grow abnormally. The loss of function for these genes may be even more significant in the development of human cancers, compared to the activation of oncogenes. TSGs can be grouped into the following categories: caretaker genes, gatekeeper genes, and more recently landscaper genes. Caretaker genes ensure stability of the genome via DNA repair and subsequently when mutated allow mutations to accumulate.[3] Meanwhile, gatekeeper genes directly regulate cell growth by either inhibiting cell cycle progression or inducing apoptosis. Lastly, landscaper genes regulate growth by contributing to the surrounding environment, and when mutated, can cause an environment that promotes unregulated proliferation.

The lung-cell type that’s most susceptible to infection by SARS-CoV-2, the virus that causes COVID-19, is not the one previously assumed to be most vulnerable. What’s more, the virus enters this susceptible cell via an unexpected route. The medical consequences may be significant. Stanford Medicine investigators have implicated a type of immune cell known as an interstitial macrophage in the critical transition from a merely bothersome COVID-19 case to a potentially deadly one. Interstitial macrophages are situated deep in the lungs, ordinarily protecting that precious organby, among other things, engorging viruses, bacteria, fungi and dust particles that make their way down our airways. But it’s these very cells, the researchers have shown in a study published online April 10 in the Journal of Experimental Medicine, that of all known types of cells composing lung tissue are most susceptible to infection by SARS-CoV-2. SARS-CoV-2-infected interstitial macrophages, the scientists have learned, morph into virus producers and squirt out inflammatory and scar-tissue-inducing chemical signals, potentially paving the road to pneumonia and damaging the lungs to the point where the virus, along with those potent secreted substances, can break out of the lungs and wreak havoc throughout the body.

The Immune System's All-Star Team: The Mighty Cells That Protect You
Your body is like a bustling city, constantly facing threats from outside invaders like viruses and bacteria. Thankfully, you have a team of dedicated defenders keeping you safe: your immune cells! Our immune system is a marvel of biological defense, tirelessly safeguarding our bodies from harmful invaders like bacteria, viruses, and parasites. At the forefront of this defense are numerous types of immune cells, each with its unique functions and capabilities. Did you know the average adult has about 2 trillion white blood cells, which contain most immune cells? That's more people than live in China! These tiny warriors come in different shapes and sizes, each with unique superpowers to protect you. Let's meet some of the key players:
The Innate Force: First up, we have the innate immune system. This frontline defense acts fast and nonspecifically, providing immediate protection against any threat. The key players: 1. Neutrophils: Think of these guys as the city's SWAT team. They're the first responders, rushing to attack invaders with toxic chemicals and swallowing them whole with their arsenal of enzymes! These are the most abundant immune cells, are short-lived but highly effective. Unfortunately, they die in the fight, leaving behind a green gooey mess (pus) that signals infection.
2. Macrophages: These are the veterans, the wise generals of the immune system. They go beyond mere engulfing, processing antigens (foreign molecules) and presenting them to other immune cells for recognition and attack. They also act as scavengers, cleaning up debris and orchestrating healing. These are the cleaners and recyclers. They gobble up dead neutrophils, debris, and even worn-out cells, keeping your city sparkling clean.
3. Natural Killer (NK) Cells: These are the ninjas of the immune system. They silently patrol, sniffing out suspicious cells infected with viruses or even cancer and eliminating them with a swift punch. The Adaptive Arsenal:
The Adaptive Arsenal: If the innate system fails, the adaptive immune system steps in. This highly specific defense remembers past encounters and tailors its response to each unique threat. The cells of adaptive immune system are:
B Cells: These are the antibody factories, producing highly specific proteins called antibodies that neutralize pathogens and toxins. Each B cell produces a unique antibody, like a lock and key, targeting specific invaders. They whip up special proteins called antibodies that lock onto specific invaders, like sticky notes, marking them for destruction.
T Cells: These are the generals, coordinating the entire defense. There are different types of T cells:
Helper T Cells: These are the commanders, directing and coordinating the immune response through chemical signals. They activate B cells, macrophages, and other immune cells, orchestrating a multi-pronged attack.
Cytotoxic T Cells: These are the elite soldiers, directly targeting and eliminating infected cells or cancer cells. They recognize and bind to specific enemy markers, unleashing a lethal attack.
Memory T Cells: These are the veterans, remembering past encounters with invaders and helping the immune system respond faster next time.
The Unsung Heroes: Beyond these main players, numerous other immune cells contribute to our defense. These include:
Dendritic cells: These antigen-presenting cells capture and process pathogens, presenting their fragments to T cells for activation. They're like the scouts, gathering enemy intel and relaying it to the command center.
Mast cells: These cells reside in tissues and release inflammatory chemicals in response to allergens or parasites. They're like the alarm system, alerting the immune system to local threats.
Eosinophils: These specialize in fighting parasitic infections, releasing toxic chemicals to neutralize them.
Basophils: These are involved in allergic reactions and contribute to wound healing.
The beauty of the immune system lies in its intricate collaboration. These diverse cell types work together in a complex and beautiful dance, each playing a specific role to achieve a common goal: protecting our health. They communicate extensively through chemical signals, creating a complex network of interactions. Imagine B cells producing antibodies that bind to a pathogen, flagging it for destruction. Macrophages engulf and eliminate the tagged pathogen, while T cells coordinate the attack and eliminate any infected cells. Dendritic cells present captured fragments to T cells, priming them for future encounters. This seamless cooperation ensures a swift and effective response to any threat.
Your immune system is constantly learning. Each time you get a vaccine or fight off an infection, your immune cells create memory T cells, making you more resistant to future attacks. Understanding these cellular heroes can help us appreciate the incredible machinery that keeps us healthy and appreciate the importance of maintaining a strong immune system. It also allows us to make informed decisions about supporting our immune system. Maintaining a healthy lifestyle, getting adequate sleep, managing stress, and consuming a balanced diet can all contribute to a robust immune response.

CaW! flower shop AU but it’s mostly centred around Memory and B
Inspired by that one fic on Ao3 except this AU is focusing on just platonic because my Aroace self is incapable of writing romance + I need more of just silly friends being silly friends
Memory is a florist who just recently opened his flower shop with the help of his friend, Shiro (U-1146 ) and the two of them run the shop together
B (No idea for human version of name ) works at a cafe the opposite of the flower shop with Mast, who owns the cafe
Also the three main RBC (AE3803, AA5100 and NT4201 ) also works there, I couldn’t think of a name for them so go ahead and make them yourself </33
Uhhhhhh basically both of the sillies saw each other and was like “Oh hey I kinda wanna be friends with him ” Idk about others but for this AU I just wanted for the relationship to be platonic or queerplatonic,,,, mostly just platonic though
Memory being an absolute idiot just sending flowers with flower language and B just being “?? Flowers?? Neat I guess ” while Mast was trying to tell him about flower language
Oh yeah this is not really important but the rest of the neutrophil squad runs a restaurant, the KTs run a tattoo shop, and the macrophages work at a maid cafe
Just decided to whip this up quickly as a distraction and to make myself feel better

Tell me why I'm writing a story on the romance between a t-lymphocyte and a macrophage. I'm getting unnecessarily attached to silly little guys that don't even exist properly yet.

A Th2 Anthem
We will bring the floods, the pain and the violence
We’ll summon the soldiers of russet and violet
To sound the sirens and slay the giant
And when the battle is over, in the damage we’ve wrought
We’ll call upon the sentinels
To stay the weather and build back better

Food WEDding with Endometriosis: there is nothing related to the bride, though; rather it's about house guests and rules
Despite being a benign condition, endometriosis causes significant morbidity in affected women, 10% of whom are of reproductive age. Endometriosis is characterized by the abnormal growth of tissues resembling that of the uterine lining or endometrium outside of the uterine cavity. Women with advanced endometriosis exhibit gut microbial changes. Previous studies have reported…

How First Medical Diagnostics Empowers Early Detection
At First Medical Diagnostics, we're more than just a healthcare provider; we're your partners in well-being. We understand that staying healthy isn't just about reacting to illness – it's about being proactive, taking charge, and living your best life. Our mission is deeply rooted in this philosophy. We're not only here to diagnose diseases and symptoms but to be your true companion in prevention.
Imagine a healthcare experience where we work together to identify potential health issues in their earliest stages. It's like having a personalized early warning system for your well-being. By catching concerns before they have a chance to disrupt your life, we empower you to stay in control and live each day to the fullest.
Why Early Detection Matters?
Early detection is a game-changer in healthcare. It can significantly improve patient outcomes and increase the chances of successful treatment. By identifying diseases or conditions at a primary stage, healthcare professionals can intervene sooner and implement preventive measures. It can also lead to cost savings, as treating a disease in its early stages is often less expensive than treating it in its advanced stages.
Early detection of a health problem leads to prompt intervention, often with less invasive and more effective options. This can result in better health outcomes and a higher chance of successful treatment. For example, if a person notices early symptoms of cancer and seeks medical attention, they may be able to receive targeted therapy or surgery, which can be less invasive than later-stage treatments like chemotherapy. For this, we offer a PanTum Test that helps in the early detection of cancer cells and prevents you from suffering in the future.
Better treatment results: There is a substantial increase in the chance of a full recovery and a successful course of treatment with early intervention. Early intervention allows for the identification and management of health conditions at their early stages, when they are most treatable. By detecting and addressing problems early on, medical professionals can prevent the progression of diseases and minimize potential complications.
Reduced burden on healthcare systems: By preventing serious illnesses, we alleviate the strain on hospitals and resources, benefiting everyone. This reduction in burden allows healthcare systems to allocate their resources more efficiently, ensuring that those who truly need medical attention receive it promptly. It also helps in decreasing waiting times for treatments and surgeries, improving overall patient care.
Specialized Tests, Powered by German Expertise:
Our specialized tests bring you the latest in German expertise, ensuring accuracy and reliability. We don't stop at just offering test results instead our group of medical specialists will assist you at every turn, providing:
Professional interpretation of your test results: We'll discuss the significance of your test results and how they may affect your health.
Personalized consultations: After talking about your lifestyle and risk factors, we'll create a strategy specifically for controlling your health and lowering your chance of getting sick in the future.
After the initial consultation, we're here to help with ongoing support and monitoring. We'll make any necessary changes to your plan and still provide ongoing monitoring.
Investing in Your Future Well-Being
Investing in early detection is a future-oriented investment. It's about assuming responsibility for your health and giving yourself the tools you need to live a longer, better life. First Medical Diagnostics is dedicated to giving you the resources required to do this.

Macrophages are innate immune cells characterized by evolutionarily conserved functions, such as host defense against infection and tissue homeostasis. Macrophages present a high plasticity grade, being able to change their phenotype in response to environmental stimuli. They play central roles during development, homeostatic tissue processes, tissue repair, and immunity. Furthermore, it is recognized that macrophages are involved in chronic inflammation and that they play central roles in many diseases, including cancers, autoimmune diseases, cardiovascular diseases, and tuberculosis.

Contact to Contract
Scarring after injury or fibrosis can be fatal as it renders tissue functionally useless. Cells called fibroblasts drive this kind of inappropriate repair, and this study reveals that contact with a kind of macrophage (large cells of the immune system, shown here in red) triggers the fibroblast (in green) – via interaction of two proteins, αvβ3 integrin on the macrophage with Piezo1 on the fibroblast – to contract ultimately leading to stiffened tissue

Immune system things
-Moths Of Disease
I hate being sick
Because being sick means your head spins around while you stay still
Your mind is flying too fast
Like little moths searching to eat its fill
They scurry around the caves inside your nose
And sneak into your lungs
They lay there to multiply and run rampant, flicking their tongues
The moths spit up poison in return
Scorching your throat and burning your skin
While you cough and cough and cough
Pesky little insects, never quite knowing when to quit
Wasted fluids, liquids and spat spit
The little moths are greedy,
They never drink their fill
But the moths will never win
I must admit I can see a great battle
In my yellowed spit and flaring heat
Little white soldiers fight
Grabbing weapons and spite
I know they will become victorious
It only takes a little time
