T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on ...

A cluster of recent studies has sharpened the scientific picture of how T cells switch on, tracking the molecular signals ...

Plant immunity is largely initiated at the cellular level, with each cell capable of autonomous detection and response, while ...

Lymph nodes, considered the command centers of our immune system, often get swollen and stiff when fighting infection. Now, a UC Berkeley-led team of researchers has discovered that this mechanical ...

Rheumatoid arthritis is a chronic autoimmune disease that affects millions of people worldwide. This disease prompts the ...

Immunotherapy has transformed cancer treatment by harnessing the body's own immune system to fight disease. But many engineered immune cells lose strength quickly after they enter the body, especially ...

Immune system activation and activity is regulated through stimulatory or inhibitory ligand-receptor interactions collectively termed immune checkpoints. 1 Stimulatory interactions give the immune ...

New research comparing four different flu vaccines found that the ability of the vaccines to activate cells of the immune system that help to protect against infection varied greatly depending on the ...

A topical treatment blocking the enzyme LSD1 activated immune responses in skin cells and slowed tumor growth in models of ...

New research identifies a specific neural pathway (Pdyn+ neurons) that carries stress signals from the brain to the skin, triggering eczema flares by activating eosinophils.
