Summary Introduction
Introduction: “Adaptive immunity” has “humoral response” and “cell-mediated response”. The humoral response is produced by the antibodies against the “pathogens in body fluids”. The cell-mediated response is produced by cytotoxic cells. The antibodies and cytotoxic cells are derived from lymphocytes. The lymphocytes develop from the bone marrow. Some lymphocytes undergo maturation in bone marrow itself, which are called as “B Lymphocytes”. The other remaining lymphocytes mature in thymus and are called as “T Lymphocytes”. Helper T cells and cytotoxic T cells are derived from “T Lymphocytes”. The macrophages are the “antigen-presenting cells” and activate the “T-helper” cells.

Which of the following would not help a virus avoid triggeringan adaptive immune response?(A) having frequent mutations in genes for surface proteins(B) infecting cells that produce very few MHC molecules(C) producing proteins very similar to those of other viruses(D) infecting and killing helper T cells
The primary function of the immune system is to protect the host from invasion by foreign organisms. But how does the immune system prevent itself from mounting attacks against its host? In other words, how does the immune system distinguish between self and nonself?
How does HIV get past our 2nd and 3rd lines of immune defense?
1.by releasing its DNA into our bodies, where the DNA is taken up by other cells
2.through blood, vaginal fluid, or semen
3.by reproducing with our immune cells
4.by attacking and infecting our immune cells
