Summary. Widespread use of lamivudine in antiretroviral therapy may lead to hepatitis B virus resistance in HIV–HBV coinfected patients from endemic settings where tenofovir is not readily available. We evaluated 389 Kenyan HIV‐infected adults before and for 18 months after starting highly active antiretroviral therapy with stavudine, lamivudine and nevirapine. Twenty‐seven (6.9%) were HBsAg positive...
Cytotoxic T lymphocytes (CTL) are critical effector cells of the immune system. Measurement of target cell damage has historically been an important measure of CTL function. CTL kill their target cells predominantly by inducing programmed cell death, or apoptosis. The gold standard for CTL-mediated cytotoxicity has been the 51Cr release assay. However, measurement of target cell lysis by 51Cr release...
Summary.HSV-1 inhibits apoptosis of the infected cell, presumably to increase viral yield. Weaker anti-apoptotic activity was previously reported in laboratory-adapted HSV-2, but not in two low-passage clinical HSV-2 isolates, suggesting that the anti-apoptotic effect might result from adaptation to laboratory growth. We therefore assembled a large panel of clinical strains of HSV-1 and HSV-2. Clinical...
