Individuals infected with herpes simplex virus (HSV) mount protective antibody responses directed against surface glycoproteins of the virus.   These antibodies are critical to viral clearance.  The act to neutralise any virus trying to infect a person’s cells as well as activating the classical pathway of complement and cytotoxic cell-mediated killing of infected target cells. Having a deficiency in the complement component C3 greatly impairs a person’s ability to control HSV infections.   To understand this further, you will investigate this in the lab.  Using C3-deficient mice, you infect them with HSV at day 0 and then a second time 4 weeks later.

Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.
