Rapporteur report

Track A report by Irene Onyango


The search for novel HIV drugs and treatment strategies that can be used for prophylactic or therapeutic purposes in humans is ongoing. Ledgins are a novel class of inhibitors targeting HIV integrase, hence capable of blocking HIV replication, that could be used in combined HIV therapy.

Viral DNA integration into the host genome is a critical step in viral replication; even if anti-integrase drugs now exist, no therapetics have been able to reverse integration so far. The Max Plank Institute has developed Tre-recombinase that effectively excises HIV-1 proviral DNA from infected human cell cultures. These data suggest that Tre-recombinase may become a novel drug for antiretroviral therapy.

HIV specific CTL responses are critical in controlling viral replication, hence there is a need to enhance these responses to suppress and clear the virus.  The positive preliminary results of a cell based therapeutic strategy that enhances CTL to eradicate the virus suggests that stem cell based gene therapy is a realistic approach.

Compromised mucosal integrity is involved in chronic immune activation, and HIV enteropathy persists despite ART. SBI has been shown to improve GI function and GALT CD4+ T cells. Th17 have been shown to be critical for mucosal immune function. The potential of IL22, which regulated IL17, should be explored as a potential immune modulator.
