Ferroptosis is implicated in viral neuropathogenesis and may underlie HIV-associated neurocognitive impairment (NCI). Emerging data also suggest differences brain iron transport by sex. We hypothesized that circulating ferritins inhibit ferroptosis associate with function NCI people HIV (PWH) a sex-biased manner. Serum ferritin heavy-chain-1 (Fth-1), light-chain (Ftl), urinary F2-isoprostanes (uF2-isoPs, specific lipid peroxidation marker) were quantified 324 PWH (including 61 women) serial global (NPZ4) domain-specific testing. Biomarker associations test scores evaluated multivariable regression; correlations uF2-isoPs assessed. Higher Ftl Fth-1 associated less all (adjusted odds ratios 0.53, 95% Confidence Interval (95% CI) 0.36-0.79 0.66, CI 0.45-0.97, respectively). In women, higher better NPZ-4 (Ftl: adjusted beta (β)=0.15, 0.02-0.29; Ftl-by-sex βinteraction=0.32, p=0.047) scores. Effects on performance persisted for up to 5 years. Levels of both correlated inversely women rho=-0.47, p<0.001). Circulating exert sustained, neuroprotective effects PWH, possibly protecting against iron-mediated (ferroptosis). Larger studies are needed confirm the observed sex further delineate underlying mechanisms.

In recent years, ferroptosis, as an emerging modality of programmed cell death, has captured significant attention within the scientific community. This comprehensive review meticulously canvasses pertinent literature past few spanning multiple facets. It delves into intricate mechanisms underpinning tracks evolution its inducers and inhibitors, dissects roles in a diverse array diseases, well resultant therapeutic implications. A profound exploration is conducted functional ferroptosis-related molecules, intracellular pathways, metabolic cascades, signaling transduction routes. Novel ferroptosis inhibitors are introduced detail, covering their design blueprints, synthetic methodologies, bioactivity profiles. Moreover, exhaustive account provided regarding involvement malignancies, neurodegenerative disorders, cardiovascular ailments, other pathologies. By highlighting pivotal status potential regimens various this aspires to furnish thorough reference framework for future investigations clinical translations domain.
