We report here the first novel HIV-1 circulating recombinant form (CRF) 54_01B (CRF54_01B) isolated from three epidemiologically unlinked subjects of different risk groups in Malaysia. These recently sampled recombinants showed a complex genome organization composed of parental subtype B' and CRF01_AE, with identical recombination breakpoints observed in the gag, pol, and vif genes. Such a discovery highlights the ongoing active generation and spread of intersubtype recombinants involving the subtype B' and CRF01_AE lineages and indicates the potential of the new CRF in bridging HIV-1 transmission among different risk groups in Southeast Asia.

Natural killer (NK) cells can efficiently mediate antibody-dependent cellular cytotoxicity (ADCC) of antibody coated target cells via the low-affinity Fc-receptor, CD16, but cannot retain antibodies over time. To increase antibody retention and facilitate targeted ADCC, we genetically modified human NK cells with the high-affinity Fc receptor, CD64, so that we could preload them with HIV-specific broadly neutralizing antibodies (BNAbs) and enhance their capacity to target HIV-infected cells via ADCC. Purified NK cells from the peripheral blood of control donors or persons living with HIV were activated with interleukin (IL)-2/IL-15/IL-21 cytokines and transduced with a lentivirus encoding CD64.

Elite controllers (ECs) and post-treatment controllers (PTCs) represent important models for achieving a functional cure for HIV. This review synthesizes findings from immunological, genetic, and virological studies to compare the mechanisms underlying HIV suppression in ECs and PTCs. Although ECs maintain viral control without antiretroviral therapy (ART), PTCs achieve suppression following ART discontinuation.

Objective: To identify novel susceptibility genes and drug targets for basal cell carcinoma (BCC).
Methods: We performed a transcriptome-wide association study (TWAS) to identified the susceptibility genes and potential drug targets for BCC. The cross-tissue TWAS was conducted to discover the candidate genes for BCC.

The emergence of drug-resistant viruses continues to be an obstacle to effectively controlling the HIV/AIDS pandemic. The development of novel drugs with high potency and the ability to fully eradicate HIV-1 infections is therefore of critical importance. Novel pyrazole derivatives were synthesized from 3-benzoylbenzofurans and characterized by mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy.

Background: Human immunodeficiency virus-1 (HIV-1) is the causative agent of acquired immunodeficiency syndrome, which is a major global health problem. Although combination antiretroviral therapy (cART) successfully expands the lifespan of HIV-1-infected patients, long-term cART often increases drug resistance and adverse effects. Therefore, efforts are ongoing to develop novel anti-HIV-1 drugs.
