ISG15-LFA1 interactions in latent HIV clearance: mechanistic implications in designing antiviral therapies.
Front Cell Dev Biol
December 2024
Biomedical Research Institute of Southern California, Oceanside, CA, United States.
Interferon types-I/II (IFN-αβ/γ) secretions are well-established antiviral host defenses. The human immunodeficiency virus (HIV) particles are known to prevail following targeted cellular interferon secretion. CD4 T-lymphocytes are the primary receptor targets for HIV entry, but the virus has been observed to hide (be latent) successfully in these cells through an alternate entry route via interactions with LFA1.

Background: Dual regimen dolutegravir/lamivudine (DOL/3TC) showed potent efficacy and favourable safety in both antiretroviral therapy-naïve and -experienced patients, but data from real life about naive people with high-level viremia are still lacking.
Methods: We performed a retrospective cohort study of people living with HIV (PLWH) who were naive to antiretroviral therapy, had baseline HIV-1 RNA ranging from 100000 to 500000 copies/mL, and initated DOL/3TC. Virological efficacy and changes in immunological parameters after 12 months of treatment were evaluated and compared with highly viremic PLWH who started a triple antiretroviral combination.
Association of circulating Treg and plasma microRNA-21 with rheumatoid arthritis progression.

The etiology of rheumatoid arthritis (RA) is multifaceted. One of the hypothesized pathways that results in the progression of RA is regulatory T cell (Treg) dysfunction. The pro-osteoclastogenic and immunogenic characteristics of microribonucleic acid (microRNA)-21 (miR-21) suggest its role in RA progression.

Agricultural Extension Directorate, MAAR Damascus Syria.
Coumarins, a group of naturally occurring compounds, have been reported to demonstrate anticancer potential. These substances, distinguished by their combined benzene and α-pyrone rings, have been demonstrated to impact multiple cellular mechanisms essential for the initiation and advancement of cancer. These agents work in different ways that prevent different tumor cells from growing, spreading, and increasing.

Purpose: Anti-programmed cell death 1 (PD1) is the first-choice treatment in patients with advanced cutaneous squamous cell carcinoma (cSCC), when curative options are unavailable. However, reliable biomarkers for patient selection are still lacking.
Experimental Design: In this translational study, clinical annotations, tissue and liquid biopsies were acquired to investigate the association between sustained objective responses and transcriptional profiles, immune cell dynamics in tumor tissue and peripheral blood samples, as well as circulating cytokine levels.
