What type of immune deficiency would you see in a child lacking the common ? chain of the receptor for cytokines IL-2, IL-4, and IL-7, among others? Explain your answer
What will be an ideal response?
Severe combined immune deficiency (SCID), characterized by an almost complete absence of T-cell and B-cell function and the inability to make any effective immune responses. Because the child cannot make functional receptors for these important cytokines, their lymphocytes cannot respond to them. The inability of naive T cells to respond to IL-2 in particular blocks the proliferation and differentiation of T cells and thus all cell-mediated immune responses and T-cell dependent antibody responses. Without treatment, children with SCID die early in infancy from common bacterial or viral infections.
