Outline of Final Research Achievements

Macrophages have been known to be one of the major target cell types for HIV-1, the causative agent of AIDS. However, there are no available data concerning half-life of infected macrophages in infected individuals. Applying combined anti-retroviral regimen to SHIV-rhesus macaque model for AIDS, we revealed that there were at least three populations of infected macrophages with distinct half-lives and that the most durable population was consisted of M2 type macrophages. It is conceivable that specific intervention of these cells would contribute to the cure for the disease.
