Detailed explanation-1: -Which of the following statements best helps explain how cell surface proteins, such as MHC proteins and T cell receptors, mediate cell communication over short distances? The proteins receive electrical signals from nerve cells.
Detailed explanation-2: -Cytokines are small and membrane-bound protein-based cell signaling molecules that aid cell-to-cell communication in immune responses and stimulate the movement of cells towards sites of inflammation, infection, and trauma.
Detailed explanation-3: -The vertebrate immune system consists of multiple types of cells that work together to protect the body from infections as well as from damaged cells. In the immune response represented above, antibodies are synthesized and secreted into the blood and the lymph.
