The T Cells also have to be activated with the help of the lymphokines which are released by both the macrophages and t helper cells. The helper T cells produce lymphokines which further activate the inactive t helper cells and convert them to memory t cells which would be helpful in interacting with the pathogen on the second response. These lymphokines also help to enhance the MHC proteins on the antigen presenting cells and convert the immunological response into a broad spectrum of events. It is then that the T cells function by either delaying the reactions of hypersensitivity or by killing the infected cells of the body (Hall & Guyton 2011; Levinson 2008).
