Abstract:
Most HIV infections worldwide are transmitted through heterosexual contact. In order to develop vaccination strategies, the basic biology of the immune system in female reproductive tract and the full range of vaginal immune responses that occur during natural HIV infection must be understood. The cervicovaginal mucosa contains a complete set of immune cells, including antigen-presenting cells, CD4+ and CD8+ T cells, and B cells. The CVS of HIV-infected women and SIV-infected female rhesus macaques contain variable levels of antiviral antibodies. Some of this variation is due to the effects of female ovarian hormone cycle. IgG antibodies make up the bulk of the antiviral antibody response. However, IgA antibodies are present at lower levels. HIV/SIV-specific CD8+ cytotoxic T lymphocytes are present in the cervicovaginal mucosa of infected women and rhesus macaques. A vaccine that can elicit strong antiviral immunity may provide protection for hetorosexual HIV-1 transmission.

What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
