WebHelper T-cells aid other cells in the immune response. When they sense an infection, they release cytokines, molecules that send messages to other immune cells. These cytokines help activate cytotoxic T-cells to fight the infection. Anatomy Where are cytotoxic T -cells located? T-cells begin to form first in your bone marrow. WebThe different cytokine patterns lead to different functions of the two types of T cell. In general, TH2 cells are excellent helpers for B-cell antibody secretion, particularly IgE responses. On the other hand TH1 cells induce delayed-type hypersensitivity reactions.
