Wound healing events in mucous tissues during early infection by Simian Immunodeficiency Virus, or SIV, guard some primate species against developing AIDS, a recent study has learned. The research looked at why certain species can carry the virus throughout their lives, and still avoid disease progression.

SIV is closely related to the Human Immunodeficiency Virus. It is used as a laboratory model for many studies seeking AIDS and HIV cures and preventions.
