Answer #1

ANS: A- An assortment of signaling proteins formed and discharged by host cells in response to the appearance of various viruses defined as interferons. in a standard framework, a virus-infected cell will release interferons producing nearby cells to strengthen their anti-viral protection.

ANS: B- Antibodies are also acknowledged as immunoglobulins, and these glycosylated protein molecules exhibit on the surface of b cells, working as antigen receptors.

ANS: C-  class I MHC molecule – CD4 not matched correctly because MHC-I interacts with CD8 and CD4 with MHC-II.

ANS: D& E- Cytolytic protein perforin located in the granules of natural killer cells and cytotoxic t lymphocytes and released from the granules of these cells to form pores in the target cell membrane.

    Adaptive Immunity: Second Line of Defense—Cellular Defenses The T-cell receptors and CD4 and CD8 molecules interact with major histocompatibility complex (MHC) proteins. MHC proteins are found on most cells of the body. There are two variations, or classes, of MHC proteins. MHC class I is expressed on the surface of most cells of the body such as skin cells, liver cells, and others. Should a cell become infected with a virus, viral antigens are processed in the cells and expressed...
