VIROLOGY: HIV-1 takes control of its own destiny

Both animal and human studies suggest that the immune molecule IFN-alpha has a role in the progression of disease in individuals infected with HIV-1. A team of researchers, led by Nina Bhardwaj, at New York University School of Medicine, New York, has now determined that HIV-1 itself is able to skew immune cells known as pDCs toward a state in which they persistently secrete IFN-alpha and uncovered the mechanism by which it does this. The team suggests that by skewing pDCs to a persistently IFN-asecreting state, HIV-1 may promote its own survival and thereby disease progression. The team also suggests that even greater understanding of the pDC/HIV-1 interaction could elucidate new therapies for HIV-1 disease.
