Destruction of CD4(+) T cells is considered to be the main cause of immunodeficiency manifested by opportunistic infections in HIV-1-infected humans, as well as in SIV-infected macaques. We propose that monocyte/macrophage lineage cells also play an important role in the pathogenesis of AIDS, based on our recent work with the SIV/rhesus macaque animal model. We propose that damage to CD4(+) T cells is important and readily apparent, but damage to monocyte/macrophage lineage cells, although less obvious, may provide the missing link to predict the onset of opportunistic infections and progression to AIDS.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

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...
