How does the cytotoxic t cell fight pathogens
WebCytotoxic T-cells can only attack cells containing pathogens your body has encountered before. It’s part of your adaptive immune system. Your adaptive immune system recognizes specific threats and launches targeted attacks. It takes about a week after an infection for your body to complete the process needed to identify a specific threat and ...

Helper T-cells: Helper T-cells recruit other immune … WebCytotoxic T cells are very specific. There is a different one for each antigen. A cytotoxic T cell will bind only to cells with an MHC 1 that is presenting the specific antigen that the cytotoxic T cell is supposed to bind to. So if a B-cell's MHC 1 is presenting the right antigen then the cytotoxic T cell will bind and kill it.
WebAdaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination. An antigen is a molecule that stimulates a response in the immune system. This part of the immune system is activated when the innate immune response is insufficient to control an infection. In fact, without information from the ...
