T cell surface markers CD4 and LAG-3 are related proteins that promote and inhibit cell activity, respectively. However, although LAG-3 has started to gain appreciation as an immune checkpoint ...

CD4+ T cells, or helper T cells, are one type of lymphocyte that helps coordinate the immune response against infection and disease. They interact and activate other cells in the immune system. The ...

The immune system uses a large number of proteins to sense the presence of microbes, including a family of proteins known as TLRs. The function of TLRs on immune cells known as DCs and macrophages has ...

Researchers of this new study found that treatment with venetoclax may be able to restore activation and proliferation of these cells, suggesting their plasticity can be leveraged for autologous ...

A study led by researchers at the University of Arizona Health Sciences discovered new information about the inner workings of the immune system that could have a profound impact on T cell therapies ...

The T-cell branch of the immune system can respond to a virtually infinite variety of antigens, in part because it includes a very large repertoire of T-cell clones, each with a unique receptor for ...

Bronchial asthma is associated with an inflammatory process that is characterized by the presence in the airways of large numbers of CD4+ T cells producing interleukin-4 and interleukin-13. However, ...

Conservation of their respective cytoplasmic tail motifs, CxC/H in the case of CD4 and an ITIM-like motif in the case of LAG-3, supports that competition between CD4 and LAG-3 for binding of kinase ...
