Systemic HIV/SIV latency reversal via non-canonical NF-κB signaling in vivo


ABSTRACT: Molecules mimicking the active N-terminal tetrapeptide of the second mitochondrial-derived activator of caspases (SMACm) potently reverse HIV latency in vitro and ex vivo without the pleotropic cellular effects seen with other LRAs. We verified that SMACm facilitate latency reversal through activation of the non-canonical NFκB pathway as exemplified by rapid degradation of cIAP1, followed by a slower conversion of inactive p100 into active p52. A potent representative of this class, AZD5582, increases cell-associated HIV gag RNA expression in resting CD4+ T cells from ART-suppressed, HIV-infected donors while altering the expression of a restricted number of human genes. These findings represent the first demonstration that SMACm have single agent latency reversal activity in patient-derived cells and support evaluation of SMACm in preclinical animal models.
