Homing, immune activation and infection

Molecular bases of human diseases

All research teams

There is a growing amount of evidences in favor of causative links between a chronic state of overactivity of the immune system and the development of morbidities such as atherosclerosis, metabolic syndrome and type 2 diabetes, liver steatosis, neurocognitive disorders, osteoporosis, frailty, and even some types of cancer.
HIV infection is a relevant model to explore these causative links. Our team is working on the chronic immune activation observed in efficiently treated HIV-1 patients (virologic responders), and on its consequences. Our working hypothesis in that each virologic responder may be characterized by one out of a few profiles of immune activation. Each of these immune activation profiles could be driven by specific causes, including persistent HIV production, microbial translocation, coinfections, CD4 T cell lymphopenia, immune senescence, and/or Th17/Treg dysregulation. Moreover, each immune activation profile might fuel specific comorbidities.
Apart from driving chronic comorbidities, the persistence of immune activation in virologic responders may impede CD4 T cell recovery. We are currently exploring one mechanism linking monocyte activation to impaired CD4 T cell restoration.
Besides immune activation, another major concern for virologic responders today is the persistence of HIV genome in the so-called « reservoir cells ». Various latency-reversing agents (LRA) have been proposed to force these reservoir cells to produce virions, with the aim of inducing their destruction. After a systematic screening of G-protein coupled receptors (GPCR) coexpressed in CD4+ T cells with the HIV coreceptor CCR5, we have identified GPCR whose activation may result in reversing HIV latency.
