by Matt Wood, University of Chicago Treg cells enforce self-nonself discrimination during infection by selectively constraining Tconv cells of shared self-specificity. Credit: Science (2025). DOI: 10.1126/science.adk3248 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 immune system can...

Technique identifies T cells primed for certain allergies or infections
by Anne Trafton, Massachusetts Institute of Technology MIT researchers have developed a method to isolate T cells that bind to different targets and then sequence their RNA. Credit: SciStories LLC When your immune system is exposed to a vaccine, an allergen, or an infectious microbe, subsets of T cells that can recognize a foreign intruder leap into action....
