Identifying stable and scalable inflammatory biomarkers that reflect domain-specific vulnerability is important for improving risk assessment in this population. Soluble urokinase plasminogen activator receptor (suPAR) is a circulating marker of immune activation with established analytical stability and prognostic value across multiple inflammatory conditions, including HIV. However, its relationship to cognitive performance in virologically suppressed women living with HIV (WLWH) is not well characterized. We conducted a cross-sectional study of 200 virologically suppressed WLWH enrolled at the Chicago-Cook County site of the MWCCS. Plasma suPAR was measured using the suPARnostic® AUTO Flex ELISA. Cognitive performance was assessed using demographically adjusted T-scores across executive function, psychomotor speed, motor function, memory, attention/working memory, verbal fluency, and learning. Multivariable linear regression models examined associations between log-transformed suPAR and continuous cognitive scores, adjusting for menopause status and suPAR storage duration. Relationships between log-suPAR and odds of impairment (T-score ≤ 40) were examined in adjusted logistic regression models. A same-visit subset was analyzed to account for timing differences between blood collection and cognitive testing. Higher log-suPAR was associated with lower psychomotor speed, lower motor function, and lower global average cognition. Odds of impairment in psychomotor speed, and motor function were higher with increasing log-suPAR. Sensitivity analyses showed consistent effect directions and magnitudes. These findings suggest that elevated suPAR reflects inflammation-related, domain-specific cognitive vulnerability in virologically suppressed WLWH and warrants further evaluation in longitudinal studies; clinical translation will require validation in larger, more demographically diverse cohorts, with concurrent assessment of menopausal and vascular risk profiles.</p>","PeriodicalId":16665,"journal":{"name":"Journal of NeuroVirology","volume":"32 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13346328/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148405275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While oncolytic virus (OV) therapy has emerged as a mechanistically distinct and promising approach, its clinical success is frequently hindered by profound intratumoral heterogeneity and emerging resistance. This critical review proposes that the efficacy of virotherapy may be meaningfully enhanced by integrating circadian biology into treatment schedules; a paradigm termed \"Oncolytic Chronovirotherapy.\" Recent evidence demonstrates that the infection cycle of neurotropic viruses, which serve as the scaffold for many OVs, is not a static process but is inherently regulated by the host's circadian clock. Fundamental studies reveal that the expression of essential viral entry receptors, such as Nectin-1 (for HSV-1) and p75NTR, exhibits robust circadian oscillations directly coordinated by the core molecular clock, specifically the BMAL1/CLOCK complex. Furthermore, the tumor immune microenvironment and cellular vulnerability to adjuvant chemotherapy (temozolomide) show synchronized peaks of activity, typically concentrated during the morning window, which often coincides with the nadir of DNA repair enzymes like MGMT. We argue that synchronizing OV administration with these windows of maximal receptor density and robust immune surveillance may maximize tumor lysis and facilitate the conversion of \"cold\" tumors into \"hot,\" immune-responsive environments. The utilization of personalized circadian biomarkers and mathematical modeling to guide therapy delivery will be essential for the next generation of precision neuro-oncology.</p>","PeriodicalId":16665,"journal":{"name":"Journal of NeuroVirology","volume":"32 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13337691/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148390996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Linear mixed models were applied to evaluate the longitudinal changes in clinical outcomes. HAND prevalence was 76.3% (84.2% for females and 72.5% for males). Multivariable linear models revealed that obesity, CD4 cell counts < 200 cells/ µL, higher hemoglobin level and hematocrit, and higher GAF scores were significantly associated with IHDS score (p < 0.05).

Longitudinal analyses demonstrated significant increases in hemoglobin, hematocrit, PCS, and MCS over time, alongside decreases in platelet count and GSI. Compared with participants without HAND, those with HAND consistently exhibited lower hemoglobin, hematocrit, GAF, and GSI scores, and higher platelet counts and MCS scores across follow-up. These findings underscore the complex interplay between hematologic and mental health, substance use, and functional status in shaping neurocognitive outcomes among PWH.
