    • Abstract:

These cells also stimulate other immune cells by exposing them to small bits of the invaders. B cytokine: b A small protein secreted by certain cells of the immune system which the body uses to have some particular controlling effect on other cells. B dendritic cell: b A type of immune system cell that initiates the primary response to a foreign substance. [Extracted from the article]
