Effects of nevirapine and efavirenz on human adipocyte differentiation, gene expression, and release of adipokines and cytokines

Abstract:

The non-nucleoside reverse transcriptase inhibitors (NNRTIs) nevirapine and efavirenz are drugs of choice for initial antiretroviral treatment for HIV-1 infection. Although NNRTIs have not traditionally been associated with the appearance of adipose alterations, recent data suggest that efavirenz may contribute to adipose tissue alterations in antiretroviral-treated patients, consistent with its ability to impair differentiation of adipocytes in cell cultures. No such effects have been reported for nevirapine, the other most commonly used NNRTI. In this study, we determined the effects of nevirapine on differentiation, gene expression and release of regulatory proteins (adipokines and cytokines) in differentiating human adipocytes, and compared them with those of efavirenz. Efavirenz caused a dose-dependent repression of adipocyte differentiation that was associated with down-regulation of the master adipogenesis …
