Answer #1

Severe combined immunodeficiency (SCID) can be caused by failure of T-cell receptor signaling. This is a genetic defect which affects the function of T cells. These cells play an important role in helping the immune system fight infections caused by foreign invaders (bacteria, virus, fungi). The children born with this defect die within one year of their birth because of having such a weak immune system.

Hence, the correct option is (c)

Hope it helps

    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...
