The diagnosis of HAND requires a battery of neuropsychological tests, which is time-consuming and burdensome, limiting its effectiveness for screening PLWH. Here, we aimed to identify biomarkers for quantitatively diagnosing and screening for HAND using minimally invasive blood tests. Neuronal-derived exosomes (neuroexosomes) were isolated from the peripheral blood of PLWH, and the transcriptomes of their microRNAs (miRNAs) were analyzed. We identified five upregulated miRNAs (hsa-miR-16-5p, hsa-miR-26a-3p, hsa-92a-3p, hsa-miR-103a-3p, and hsa-miR-185-5p), and two downregulated miRNA (hsa-miR-3613-3p and hsa-miR-4668-5p) in PLWH diagnosed with HAND (HAND PLWH). Functional analysis of five miRNAs whose expression levels increased in HAND PLWH using the database showed that these miRNAs are involved in motor proteins and endocytosis, which are associated with nerve function. The expression levels of hsa-miR-16-5p, hsa-miR-103a-3p, and hsa-miR-185-5p were significantly higher than those in the non-HIV controls and non-HAND PLWH, suggesting that these miRNAs are potential biomarkers for HAND.

Chronic inflammation and immune activation are thought to be an underlying cause of these comorbidities. Many of the factors thought to drive chronic inflammation and immune activation in HIV overlap with factors known to induce trained immunity. Trained immunity is a form of innate immune memory that metabolically and epigenetically reprograms innate immune cells to mount enhanced inflammatory responses upon secondary encounter with unrelated inflammatory stimuli. While this phenotype has been characterized in a variety of disease states in animals and humans, very little is known about its potential contribution to chronic HIV pathogenesis. In this review, a broad overview of innate immune memory in the periphery and the central nervous system (CNS) is provided and the evidence for trained immunity in the context of HIV is considered. In PLWH on ART, this phenotype could contribute to the chronic inflammation and immune activation associated with HIV comorbidities and could complicate HIV cure strategies due to the potential persistence of the phenotype after eradication of the virus. Further research into this immune state in the context of HIV may open the door for new therapeutics aimed at treating HIV comorbidities like HAND.</p>","PeriodicalId":16665,"journal":{"name":"Journal of NeuroVirology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142895595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we evaluated functional parameters of astroglial cells exposed to ZIKV upon normal and high glucose concentrations, focusing on inflammatory profile, oxidative stress, and expression of critical genes for astroglial functions. High glucose potentiated the pro-inflammatory and oxidative effects of ZIKV, as well as potentiated the downregulation of signaling pathways, such as Nrf-2 (nuclear factor erythroid derived 2 like 2), sirtuin 1 (SIRT1), peroxisome proliferator activated receptor gamma coactivator 1-alpha (PGC-1α), and poly (ADP-ribose) polymerase (PARP).

The neurologic manifestations of PASC (Neuro-PASC) are among the most debilitating but they are largely unreported in Africa. We sought to compare the demographics, symptoms and cognitive profile of post-hospitalization Neuro-PASC (PNP) and non-hospitalized Neuro-PASC (NNP) patients in Nigeria. In this cross-sectional study performed at the Lagos University Teaching Hospital, 106/2319 (4.6%) SARS-CoV-2 positive individuals contacted via telephone reported Neuro-PASC symptoms with a higher frequency in PNP than in NNP individuals ((23/200 (11.5%) vs. 83/2119 (3.9%), p = < 0.0001). The predominant neurologic symptoms at any time during the disease course were difficulty remembering / brain fog (63/106; 59.4%), fatigue (59/106; 55.7%), sleep problems (34/106; 32%), headache (33/106; 31%), paresthesia (12/106; 11.3%), and myalgia (10/106; 9.4%). Of 66 participants with Neuro-PASC who underwent in-person neurological evaluation and cognitive screening, all had normal scores on the Intervention for Dementia in Elderly Africans cognition screen, while 11/65 (16.9%) that completed the Montreal Cognitive Assessment had results consistent with mild cognitive impairment (3/16 PNP (18.8%) and 8/49 NNP (16.3%); p = 1.0).
