The advent of combination anti-retroviral therapy (cART) has greatly improved the quality of life of infected individuals; however, roughly 50 % of these individuals will still experience HIV-1-associated neurocognitive disorders (HAND) . Additionally, the gastrointestinal microbiome has been reported to be dysbiotic in HIV-1 infected individuals, regardless of adherence to cART. Current research has pointed to the gut-brainmicrobiota axis as a potential target to treat both cognitive deficits and microbial changes. The present study investigated S-Equol (SE) as a potential therapeutic for HAND by modulating the gastrointestinal microbiome.  \nMethods: The study included 21 HIV-1 Tg rats and 21 F344 control animals to test the effect 0.2 mg SE has on cocainemaintained responding on a PR schedule of reinforcement. Results: Gastrointestinal microbiome alterations between genotypes were found at the phylum and genus level, regardless of treatment group, and SE treatment had both main effects and interactions with genotype. Prevotella_UCG_001 was significantly associated with lever presses for drug, suggesting an effect on motivation for cocaine. Alloprevotella was found to significantly differentiate between genotype by treatment effects, indicating that SE differently affects genotypes.  \nCurrent address: Sarah J.

Combination antiretroviral therapy (cART) is the main treatment for HIV and works to control the replication of HIV, resulting in improved CD4 T cell counts and preventing transmission to others by those compliant with the cART regimen (WHO, 2022) . The use of cART has also greatly decreased the prevalence of HIV-1-associated dementia (HAD), but HIV- 1-associated neurocognitive disorders (HAND) continue to persist, affecting approximately 50 % of HIV-1 seropositive individuals regardless of cART treatment [2] . Treatment is usually started as soon as a diagnosis is made but by then the infection has already established latent, viral reservoirs, that prevent full eradication of the virus by antiretrovirals, due to an inability of cART to reach these latent reservoirs [3] . The infection enters the body through the exchange of bodily fluids (blood, semen, and vaginal secretions) with an infected individual. Once inside the body, HIV-1 initially binds to CD4+ T cells via the C-C chemokine receptor type 5 (CCR5) co-receptor. The gastrointestinal (GI) tract contains the largest mucosal immune system, making it ","cbCaivwwyRWOunc3","https://ap.wps.com/l/cbCaivwwyRWOunc3","pdf",1404872,13,"English","# Introduction\n## HIV-1, cART, and persistent HAND\n## Gastrointestinal dysbiosis and mechanisms\n## Gut-brain-microbiota axis as a treatment target\n# Methods\n## Animal model and S-Equol dosing\n## Behavioral and reinforcement testing\n# Results\n## Microbiome alterations by genotype and treatment\n## Prevotella associations with cocaine lever pressing\n## Genotype-specific differentiation by Alloprevotella","[{\"question\":\"What was the main objective of the study on S-Equol?\",\"answer\":\"To assess whether S-Equol can serve as a potential therapeutic for HIV-1-associated neurocognitive disorders by modulating the gastrointestinal microbiome.\"},{\"question\":\"How was S-Equol tested in the study?\",\"answer\":\"The study used 21 HIV-1 Tg rats and 21 F344 control animals to test the effect of 0.2 mg S-Equol on cocaine-maintained responding under a PR reinforcement schedule.\"},{\"question\":\"What microbiome findings were reported after S-Equol treatment?\",\"answer\":\"Genotype-related gastrointestinal microbiome alterations were observed at the phylum and genus levels, and S-Equol showed main effects and interactions with genotype; Prevotella_UCG_001 related to drug lever pressing and Alloprevotella differentiated genotype by treatment effects.\"}]","S-Equol - a novel therapeutic for HIV-1-associated gastrointestinal dysbiosis | PDF",1790579088,33]
