WebThey are not only efficient at presenting peptide antigen but can also process and present soluble protein antigen sto antigen-specific T cells and cloned T cell lines. They are very strong stimulators of both allogeneic and syngeneic mixed lymphocyte reactions and have a unique capacity to stimulate naive T cells. WebThey proliferate - like any other cell - exponetially as long as there is an "ongoing" signal* to do so. (*by T-Cells, Cytokines and Antigens - not like any other cell) ... Actually, part of the cytotoxic T cell activation can be assisted or kind of given a boost by these cytokines-- of so by these alarm bells. So this guy's the alarm ringer ...

WebApr 26, 2024 · Helper T cells play a central role in the functioning of the adaptive immune system and are required for almost all adaptive immune responses. They don’t secrete toxins or antibodies, and they don’t directly attack pathogens. Instead, they ‘help’ by secreting cytokines that activate various other immune cells and coordinate the … WebTNF (tumor necrosis factor) is both a pro-inflammatory and anti-inflammatory cytokine that is central to the development of autoimmune disease, cancer, and protection against infectious pathogens.
