Which type of T cell provides a prime target for AIDS? explain
Homework Answers
Helper T cells are prime target in AIDS,leading to eventual death of cell. CD4 cells are vital players in regulation of immune response to invading microorganisms.massive viral replication leads to progressive loss of CD4 cell over period of several years to long as decade.
HIV infects and deletes CD4+ T cells that normally coordinate the adaptive T and B cell response to defend against intracellular pathogens.

HIV, the virus which causes AIDS, interacts with two receptors on the host cell membrane: CD4 and CCR5. A small percentage of individuals have a genetic mutation which causes their cells to lack CCR5. These individuals will never develop AIDS nor are they able to pass HIV on to others. Which part of viral replication is being blocked by the lack of a receptor? Select one: o a. Newly assembled virions cannot be released from the host cell. O b....

A) HIV functions by infecting healthy CD4+T cells, a type of white blood cell, that are necessary to fight infection. As the virus embeds in a T cell and the immune system produces more of these cells to fight the infection, the virus propagates in an opportunistic manner. Normally, T cells are produced at a rate s and die at a rate d. The virus, when present in the bloodstream as free virus, infect health T cells at a rate...
