Consider the events that occur in HIV infection. I. HIV undergoes molecular self assembly.II. The protein gp120 binds to CD4.III. The HIV genome is incorporated into the host cell genome.IV.

Match the type or cause of clonal expansion with the correct situation. Use each choice just one time and make the best match. Clonal expansion of B cells because the cells are infected with EBV Clonal expansion of B-cells because these B-cells have B Cell Receptors that recognize a non-self antigen Clonal expansion of T-cells that have a T Cell Receptor that recognizes EBV antigens A. normal adaptive response by the B cells B. part of pathogenesis of mono C. This allows the adaptive immune system to shut down active EBV infection
If you come down with the flu, your body will launch an immune attack against the flu virus. During the recognition phase of the adaptive immune response: a an antigen of the virus will be presented by an antigen-presenting cell and be recognized by T-helper cells b B cells will recognize the viral particles and produce antibodies against them c cytotoxic T cells will recognize the virus-infected cells and kill them d antibodies will recognize the viral antigens, bind to them, and attract phagocytes e a T-helper cell will recognize the viral antigen and stimulate B cells and cytotoxic T cells to divide
