Project context and summary: Natural Killer cells are known to play a crucial role in protective immunity against viral infection and cancer. The inflammatory state, induced by the metabolism challenge of obesity, strongly interferes with the function of immune cells and obesity has been associated with NK cell dysfunction.
We have shown that they play an important role in the control of SIV/HIV replication in secondary lymphoid organs. During the last years, obesity has become a major global public health issue.Recent studies have shown that the prevalence of obesity in people living with HIV (PLWH) has increased over the last two decades, partly due to the aging of the population of people living with HIV, improved access to treatments and in some cases following the introduction of specific antiretrovirals.
In this project, we propose to investigate the consequences of obesity on the NK cells.
