8 linking the immune system to chronic stress. This led them to hypothesize that a small number of immune cells might infiltrate regions near the brain during stress but evade detection by the ...

CD4 T helper cells are a type of white blood cell called a lymphocyte that serves an important role in your immune system. These cells help defend the body against infection by directing other "killer ...

T cells are essential for mounting an effective immune response against tumors. However, once they enter the tumor environment, they are exposed to various stressors that alter their development ...

Researchers found that the immune system can influence stress and fear behaviors by changing how brain cells communicate. Mass General Brigham researchers found that interactions between immune ...

These are made by the immune system and are important for defending the body against infections. Cytokines help control inflammation and tell other immune cells what to do. But now it’s becoming ...

An antibody (teal) bound to its target, the HIV protein Env (white and gray), also attaches to an immune cell via a receptor (red) on the immune cell’s surface. This interaction can activate the ...

The researchers found that the activation of NLRP3 and AIM2 inflammasomes -- proteins in immune cells that detect threats and trigger a response -- is a key factor in severe inflammatory responses ...

Prior to this, we assumed there were no microglia-like cells outside the CNS (central nervous system)." Immune cells play significant roles in embryonic development, organ formation, maintaining ...

IgG4-RD is an immune-mediated disorder. When someone has it, their immune system goes into overdrive ... For example, if an accumulation of cells block the bile ducts, a patient can develop ...
