HIV works by infecting and destroying Helper T-Cells. If someone has significantly reduced Helper T cells, how would this affect the immune response? No answer text provided. Interferon; Complement Antigens could not be detected by the B cells The B cells would not be able to mature in the thymus and there would be no cell-mediated response The B cells would not be activated, and there would be no humoral response Which of these cells functions as an antigen presenting cell, and which membrane protein does it utilize to do so? Plasma Cell; antibodies Dendritic Cell; MHC II The B cells would not be able to detect antigen presenting cells Helper T Cell; Killer T Cells

6) (2 points) Your body has been invaded by pathogenic bacteria! Explain how your B lymphocytes will respond and how this response can ultimately result in the death of the invading bacterial cells. 7) (1 point) HIV specifically targets helper T cells. Explain why the loss of helper T cells is particularly damaging to your overall immune response (e.g. what do helper T cells do and what would happen if did not have helper T cells). 8) (1 point) Suppose a person lacks the capability to produce any memory cells, but otherwise has a normal immune system. How would this difference change the immune response when this person is exposed to a pathogen for a second time?

12. The cells in the body that are target cells for HIV are 13. Cytotoxic T cells act by 14. In order for a helper T cell to interact with a macrophage or B cell and become activated 15. Transfusion of an incorrect blood type into a person will cause a form of tissue rejection mediated by 16. When AIDS develops 17. One distinction between B cells and T cells is that
A nonfunctional CD4 protein on a helper T cell would result in the helper T cell being unable to properly recognize and bind to antigens presented by antigen-presenting cells. This would impair the helper T cell's ability to activate other immune cells and coordinate an effective immune response.
