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 ...

Interleukin-9 (IL-9) is a multifunctional cytokine that plays a critical role in regulating immune responses, allergic inflammation and host defence mechanisms. T helper 9 (TH9) cells, a specialised ...

CD4+ T cells, or helper T cells, are one type of lymphocyte that helps coordinate the immune response against infection and disease. The cells are crucial in achieving a regulated effective immune ...

Our immune system constantly evolves over the years, and certain cells long considered signs of decline might actually play a ...

Researchers led by Yasuhiro Murakawa at the RIKEN Center for Integrative Medical Sciences (IMS) and Kyoto University in Japan and IFOM ETS in Italy have discovered several rare types of helper T cells ...

CD4+ T-cells, primarily considered to play a supportive role in the anti-tumor immune response, have been seen to actively kill cancer cells in a mouse model of melanoma. A recent study by a team at ...

HIV infects immune cells and establishes long-lasting infections that can progress to acquired immunodeficiency syndrome (AIDS) if left untreated. With the advancement of antiviral therapy (ART), HIV ...
