The transplantation of organs from one person to another was impossible until the discovery of immunosuppressive drugs. Now, with the use of drugs such as cyclosporine, organs can be transplanted without rejection. Transplant patients must take immunosuppressive drugs for the remainder of their lives. What are the potential risks associated with long-term use of immunosuppressive drugs?
A man gets bitten by a rattle snake. The man is rushed to the hospital and they administer to him
anti-rattle snake venom. The anti-rattle snake venom is horse antibodies that were raised against
rattle snake venom, and it provides immunity against rattle snake venom. Based on what you
studied in the lecture: A) what is the type of immunity that antivenom provides? B) Are the
antibodies part of the innate or the adaptive immune responses? C) From what you have learned
about the properties of antibodies, can this horse anti-rattle snake venom be used as anti-venom to
Cobra snake venom? Explain briefly. D) Six months after this incident, the same person got bitten
again by a rattle snake. However, at the hospital the doctors were informed that he was previously
given horse anti-venom and so they decided that this person cannot be injected again with horse
anti-venom, and they had to find an anti-venom not prepared in horse. Explain briefly why he
cannot get any horse anti-venom again,…
Superantigensa) are exceptionally large antigen molecules.b) cause a very large antibody response.c) elicit a response from a large number of T cells.d) attach non-specifically to B-cell receptors.e) assist in a protective immune response.
