the specific immune response Flashcards
what are the cells produced by the immune system
T helper cells- release cytokines that stimulate B cells to develop and stimulate phagocytosis by phagocytes
T killer cells - attack and kill host-body cells that display
the foreign antigen
T memory cells - provide long-term immunity
T regulatory cell- shut down the immune response after the pathogen has been successfully removed. they are also involved in preventing autoimmunity
Plasma cells - circulate in blood manufacturing and releasing antibodies.
B memory cells - which remain the body for a number of years and act as the immunological memory
what is cell signalling?
when a hormone is released to other cells to work together and efficiently.
examples of cell signalling? (3)
macrophages release monokines. some monokines attract neutrophils and others stimulate B cells to differentiate and release antibodies.
T cells release interleukins, stimulate clonal expansion and differentiation of B and T cells
many cells can release interferon which inhibits virus replication and stimulates activity of T killer cells.
