Cytotoxic t cells are activated by
WebT cells possess the ability to be activated independently of their cognate antigen stimulation, i.e. without TCR stimulation. At early stages of infection, T cells specific for unrelated antigen are activated only by the presence of inflammation. WebT cells are so called because they are predominantly produced in the thymus. They recognise foreign particles (antigen) by a surface expressed, highly variable, T cell …
