Our immune system made up of various cells among them some special chemical sensing cells are there, which can detect a minor immune stimuli and act on that stimuli accordingly. Basically CD25 is a sort of specific protein in the immune system for its regulation. CD25 is alpha chain of IL-2 (interleukin two), which regulates several immune factors in human. Therefore, correct option would be “The α-sub-unit of IL-2 receptor”
14. Cytokines are specific cellular molecules, which act whenever a cell faces any endogenous or exogenous invasion of enemy (pathogen) to the body. These polarized cytokines get activated in the presence of active antigen, like polarization of T cell (thymus maturation of lymphocytes) where as TH stands for T helper cells. Hence, in this scenario the most relevant answer would be “The type of cytokines produced by an effector TH cell” rest other choices are not completely relevant.

All of the following reasons contribute to the current low usages of cytokine therapy in medicine EXCEPT: A. Cytokines have a short half-life, usually less than 10 min. B. Cytokines may be bound by soluble receptors and never reach their target cell. C. Cytokine injections often cause an allergic reaction because rabbits make...

1.One group of immune deficiency diseases is caused by an inability of CD8 effector T cells to kill virus-infected target cells, due to defects in cytotoxic vesicle exocytosis. Because of the inflammatory response that accompanies a normal virus infection, together with the prolongation of this response due to the inability to control the infection, patients with these disorders suffer from tissue damage caused by the infiltration of effector CD8 cells and activated macrophages into multiple organs. In addition, a subset...
