Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ...

For the first time, researchers at the University of British Columbia have demonstrated how to reliably produce an important type of human immune cell known as helper T cells—from stem cells in a ...

Researchers at the Medical University of Vienna have taken a closer look at a previously largely unknown component of the immune system: the protein molecule TRAT1 (T Cell Receptor Associated ...

CD4 T helper cells help the body fight infections by signaling other cells to attack germs. Without enough CD4 T cells, the body can't fight diseases like HIV and becomes immunocompromised. HIV ...

Immunologists have identified a previously unrecognized group of immune cells that could reshape how vaccines and immune-based therapies are designed. The newly described cells 1 are long-lived memory ...

Rheumatoid arthritis (RA) is an autoimmune disease that affects millions worldwide and can have a devastating impact on patients' lives. Yet, about one in three patients respond poorly to existing ...

During infections, the immune system needs to distinguish foreign antigens that are expressed by invading bacteria and viruses from self-antigens that are expressed by cells of the body. If not, the ...

A new study identifies an extreme but effective way that brain immune cells can prevent the parasite Toxoplasma gondii from spreading: they kill themselves to eliminate the dangerous microbes they ...

A new study has shed light on why patients with certain rare immune disorders develop severe, food-triggered allergic reactions while others with similar diagnoses do not. The findings, published in ...
