CRF01_AE and CRF07_BC are predominant circulating HIV-1 subtypes in China. In this study, we report two novel HIV-1 CRF01_AE/CRF07_BC recombinant forms isolated from one man who has sex with men (MSM) (BDD027) and one mother-to-child transmission (MTCT) case (BDL123) in Baoding City, Hebei Province, China. The recombination breakpoint analysis showed that the recombination pattern of the near-full-length genome of BDD027 consisted of two CRF07_BC fragments inserted into a CRF01_AE backbone, while the recombination pattern of the near-full-length genome of BDL123 consisted of one CRF01_AE fragment inserted into a CRF07_BC backbone. This study demonstrates the importance of strengthening the monitoring of HIV-1 molecular epidemiological characteristics and emphasizes the urgent need to reduce the HIV-1 epidemic among MSM and MTCT populations in China.

The emergence of CRF80_0107 resulted from recombination between co-circulating CRF01_AE and CRF07_BC genotypes. To date, no secondary recombinants involving CRF80_0107 as a parental strain have been documented in public sequence databases. Here, we report the identification and characterization of a novel HIV-1 CRF80_0107/B recombinant form isolated from a treatment-naïve men who have sex with men (MSM) individual in Baoding City, Hebei Province, China.

Background: The intestinal microbiota composition has been linked to neurocognitive impairment in people with HIV (PWH). However, the potential interplay of microbial species and related metabolites, particularly in the context of an HIV cure strategy remains underexplored. The BCN02 trial evaluated the impact of romidepsin (RMD), used as a HIV-1 latency reversing agent and with reported beneficial neurological effects, combined with the MVA.

Herpes simplex virus 2 (HSV-2) is a major pathogen causing neonatal herpes and increasing the risk of human immunodeficiency virus 1 (HIV-1) infection. However, the mechanisms underlying host restriction of HSV-2 infection are still not fully understood. The ubiquitously expressed transcript isoform 2 (UXT-V2), an α-type prefoldin protein, functions as a versatile transcription factor associated with numerous human tumors, but its role in viral infection remains unclear.

A strategy to functionally cure AIDS by eliminating latent HIV-1 reservoirs involves non-nucleoside reverse transcriptase inhibitors (NNRTIs) that promote pyroptosis of HIV-1 infected cells. These NNRTIs stimulate dimerization of the Gag-Pol polyprotein, resulting in premature HIV-1 protease (PR) dimerization and cleavage of intracellular CARD8. A unique cell-based high-throughput screen was developed to identify potent compounds activating the CARD8 inflammasome through Gag-Pol dimerization.

Mathematical modeling and numerical simulation are valuable tools for getting theoretical insights into dynamic processes such as, for example, within-host virus dynamics or disease transmission between individuals. In this work, we propose a new time discretization, a so-called non-standard finite-difference-method, for numerical simulation of the classical target cell limited dynamical within-host HIV-model. In our case, we use a non-local approximation of our right-hand-side function of our dynamical system.
