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 ...

A newly recognized set of T helper cells seems to guard against aging by eliminating harmful senescent cells. Their presence in supercentenarians suggests they may be a key to maintaining a healthier, ...

A research team has made further progress in the treatment of intestinal inflammation. A study shows that the semi-synthetic bile acid NorUDCA inhibits in the intestine the formation of ...

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 ...

Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve ...

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 ...

During infections, the immune system needs to distinguish foreign molecules from invading bacteria and viruses from molecules that are made by cells of the body. If it can’t, the immune system can ...

After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown in a new study how activity of "good" microbes in the gut is linked to ...
