This is the Reason Why Some Species of African Monkey Origin of AIDS Invulnerability

Several species of African monkeys such as sooty mangabey origin (Cercocebus atys) known to have a natural defense mechanism that prevents them from becoming infected with HIV. Primates infected with the virus is reported to simian immunodeficiency virus (SIV) without developing into AIDS even though the amount of the virus very much.

The phenomenon commonly known as natural hosts are currently being studied by scientists to study the development of drugs of HIV / AIDS to humans.

The scientists found the monkeys on the body of the T cell regeneration occurs, the type of white blood cells that make the immune system can fight germs or viral infections.

In particular note the sooty mangabey monkeys infected by SIV or HIV virus in nonhuman primate relatives are able to maintain levels of CD4 and T cells through rapid regeneration of CD4 and T cells are smooth or have not been exposed to toxins and other compounds that stimulate antibody production.

The result of such research could explain why SIV and HIV can cause AIDS in other primates, including humans. In this study, scientists from Yerkes National Primate Research Center, Atlanta, comparing with the sooty mangabey SIV-infected rhesus monkeys.

"Although the two species showed accretion CDH4 cells and T cells, but in rhesus monkeys appear regeneration of naive CD4 T cells more slowly," said Mirko Paiardini, one of the researchers.
