Gut bacteria metabolism impacts immune recovery in HIV-infected individuals, study finds

Researchers from the University of Valencia (UV) have taken part in a study analysing the influence of gut bacteria on immune recovery in HIV-infected patients undergoing antiretroviral treatment (ART). They have discovered a correlation between immune recovery and the behaviour of a certain subset of gut bacteria in reponse to treatment. Interestingly, this behaviour appears to be both a consequence and a cause of recovery.

The implications of this finding are that new complementary therapies could be developed that target these bacteria to boost the efficiency of ART and prevent the complications associated with immune deficiency and chronic inflammation.

"HIV patients suffer from persistent immune deficiencies and chronic intestinal inflammation caused, in part, by the very toxins released by the cells to fight off the HIV infection. In this study we have found that, in some patients, certain gut bacteria become activated during ART and begin to amass anti-inflammatory molecules", explains CSIC researcher Manuel Ferrer of the Catalysis Institute. The immune recovery of these "ART responders" is much better than that of their peers, the make-up and behaviour of whose gut bacteria does not lead to the same anti-inflammatory effect.
