We studied the ex vivo and in vitro expression of CD95/Fas and CD127 receptors in total, naive and memory CD8+ T cells from HIV infected patients with different blood counts of CD4+ T cells. In addition, spontaneous and induced apoptosis were determined in vitro using a viral antigen (Env), along with an evaluation of their specific proliferative capacity.(More)
Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the cystic fibrosis transmembrane regulator (CFTR) gene. About 2000 mutations have been described so far. We setup an ex vivo model of human nasal epithelial cells (HNECs) to study CF patients testing the effect of novel mutations and molecular therapies. We performed sampling (by(More)
We have studied 65 HIV-1-infected untreated patients recruited in Caracas, Venezuela with TCD4 counts > or =350/microl. The reverse transcriptase and protease sequences of the virus were sequenced, aligned with reference HIV-1 group M strains, and analyzed for drug resistance mutations. Most of the viruses were subtype B genotype in both the protease and RT(More)
