Impaired osteoblast/osteoclast cross-talk and bone structure homeostasis resulting in osteopenia/osteoporosis are often observed in HIV seropositive patients but the causal mechanisms remain unsettled. This study analyzed the biological effects of Tat on peripheral blood monocyte-derived osteoclast differentiation and our results show that Tat may be considered a viral factor positively modulating the osteoclastogenesis and then bone resorption activity suggesting a pathogenetic role of this viral protein in the HIV-related osteopenia/osteoporosis.

Abstract
Impaired osteoblast/osteoclast cross-talk and bone structure homeostasis resulting in osteopenia/osteoporosis are often observed in HIV seropositive patients but the causal mechanisms remain unsettled. This study analyzed the biological effects of Tat on peripheral blood monocyte-derived osteoclast differentiation and our results show that Tat may be considered a viral factor positively modulating the osteoclastogenesis and then bone resorption activity suggesting a pathogenetic role of this viral protein in the HIV-related osteopenia/osteoporosis.File in questo prodotto:
