Air pollution may promote asthma and worsen lung diseases by altering immune regulation and increasing oxidative stress, according to recent research on mice.

Reagents That Distinguish Th1 and Th2 cells Courtesy of R&D SystemsSchematic representation of cytokines influencing the development of antigen-activated naive CD4+ T cells into Th1 and Th2 cells.

Two major CD4+ T-helper (Th) lineages are Th1 and Th2, and well balanced Th1/Th2 responses are essential for immune function. In previously published studies, it was reported that radiation induces a ...

Mast cells trigger T-helper type 2 cells (Th2), which counteract the Th1 response that is responsible for identifying and destroying viruses and virus-infected cells.

It demonstrated that the Th1 memory CD4 + T cells trafficking into the skin were Ly6C + T EM and synthesized core two O-glycans. More importantly, these cells exhibited robust anti-viral activity ...
