Answer #1

When virus infect a body cell it invade inside the cell and our immune system cannot find the virus. The virus replicate and survive inside the cell. This problem is solved by MHC molecule. The virus produces some new protein inside the cell. Some of the viral protein tagged for degradation enters endoplasmic reticulum and here MHC molecule bind with it. MHC class 1 molecules display these protein on the surface of the cell. This may also occur via interferon. An infected cell produce small amount of interferon which play a role in protection from virus. This also act as signal which trigger the presentation of MHC molecule upon the surface of the cells. This enables T-cell to identity and eliminate the virus.

1. Neutralizing antibodies are effective at preventing infection or toxicity mediated by pathogens or their toxic products. In fact, nearly all vaccines currently in use function by eliciting neutralizing antibodies. The most important feature of a neutralizing antibody is: A. Having a high degree of multi-valency, such as being a pentamer or hexamer of immunoglobulin monomers B. Having high affinity for the antigen C. Being present at a high concentration in the circulation D. Being efficient at activating the complement...

Adaptive immunity has several features that distinguish it from innate immunity. Specificity in that each adaptive immune response is induced by a particular antigen, or surface feature that generates an antibody. An innate immune response might be stimulated by a PAMP, while an adaptive immune response is stimulated by a single feature of a bacteria. In addition, cells of adaptive immunity, B and T cells, are allowed to proliferate under certain conditions to mount a defense, this feature is clonality...

One of the most noted secondary immunodeficiencies occurs with infection by the human immunodeficiency virus, or HIV. In the United States, over 1 million individuals are infected with HIV annually. HIV infects CD4 cells, also called helper T cells. The virus can remain dormant in these cells until they begin to replicate. As CD4 cells replicate the virus, the cells are destroyed, and the body’s immune responses weaken. The symptoms that appear following HIV infection are usually mild and flu-like....
