Why monkeys immune to HIV, Recent research

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

The phenomenon commonly known as a natural host currently being examined by scientists to study the development of drugs of HIV / AIDS to humans.

The scientists found that in monkeys body occurred regeneration of T cells, white blood cell types that make the immune system to fight germs or viral infections.

In particular note Sooty Mangabey monkeys infected with SIV or HIV virus in primate relatives able to maintain levels of CD4 and T cells through the rapid regeneration of CD4 and T cells, innocent or not 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 primates, including humans. In this study, scientists from Yerkes National primates Research Center, Atlanta, Sooty Mangabey compare the rhesus monkeys infected with SIV.

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