Transmitted/founder SHIV.D replicates in the brain, causes neuropathogenesis, and persists on combination antiretroviral therapy in rhesus macaques.
A biologically relevant non-human primate (NHP) model of HIV persistence in the central nervous system (CNS) is necessary. Most current NHP/SIV models of HIV infection fail to recapitulate viral persistence in the CNS without encephalitis or fail to employ viruses that authentically represent the ongoing HIV-1 pandemic. Here, we demonstrate viral replication in the brain and neuropathogenesis after combination antiretroviral therapy (ART) in rhesus macaques (RMs) using novel macrophage-tropic transmitted/founder (TF) simian-human immunodeficiency virus SHIV.D.191,859 (SHIV.D). Quantitative immunohistochemistry (IHC) and DNA/RNAscope in situ hybridization (ISH) were performed on three brain regions from six SHIV.D-infected RMs; two necropsied while viremic, two during analytical treatment interruptions, and two on suppressive ART. We demonstrated myeloid-mediated neuroinflammation, viral replication, and proviral DNA in the brain in all animals. These results demonstrate that TF SHIV.D models native HIV-1 CNS replication, pathogenesis, and persistence on ART in rhesus macaques.
期刊介绍：
Retrovirology is an open access, online journal that publishes stringently peer-reviewed, high-impact articles on host-pathogen interactions, fundamental mechanisms of replication, immune defenses, animal models, and clinical science relating to retroviruses. Retroviruses are pleiotropically found in animals. Well-described examples include avian, murine and primate retroviruses.
Two human retroviruses are especially important pathogens. These are the human immunodeficiency virus, HIV, and the human T-cell leukemia virus, HTLV. HIV causes AIDS while HTLV-1 is the etiological agent for adult T-cell leukemia and HTLV-1-associated myelopathy/tropical spastic paraparesis. Retrovirology aims to cover comprehensively all aspects of human and animal retrovirus research.
