599 – Polypharmacy Is Associated With Neuronal Injury in PWH

Background Polypharmacy, or the use of five or more non-ART prescription medications, promote neurologic disorders and geriatric syndromes. However, it is unknown if this is mediated by neuronal damage incurred by multiple medications, by inflammation, or by high comorbidity burden necessitating the use of multiple medications. To better understand how polypharmacy influences neurologic disorder in…

946 – Shared Autoantibody Signature Is Not Identified in CSF During Long COVID

Background A subset of people who recover from acute COVID-19 develop a range of emergent or persistent symptoms lasting months to years, collectively termed Long COVID (LC). We investigated whether autoimmune antibodies in the CNS associate with neurologic Long COVID symptoms (n-LC). Methods Participants with LC (WHO criteria) and cognitive symptoms or headache enrolled in…

629 – Adenosine, Guardian of the Brain: Possible Role in Protecting From HIV Neuropathogenesis

Background Due to its regulatory properties, adenosine has been recognized as a guardian molecule with many protective functions in and out of the brain. For example, HIV silencing in T-cells has been associated with upregulating the adenosine-producing ecto-5’-nucleotidase Nt5e (known as CD73). We hypothesized that under HIV-induced inflammatory conditions in the brain extracellular ATP/adenosine would increase and…

594 – Analyzing Neuroanatomical Heterogeneity in HIV-Associated Cognitive Impairment

Background Central Nervous System (CNS) complications among people living with HIV (PWH) are common, but treatments remain elusive, likely due to underlying heterogeneity. Here, we aim to characterize neurobiological heterogeneity in PWH by leveraging machine learning and neuroimaging data in a large, well-characterized cohort. Methods We analyzed structural Magnetic Resonance Imaging (sMRI) data from 610…

600 – Plasma CNS Tissue Markers in Heavily Treatment-Experienced PWH in the PRESTIGIO Registry

Background Heavily treatment-experienced (HTE) persons with HIV (PWH) are characterized by long infection and treatment history, resistant viruses, and a significant burden of concomitant diseases. Since these features may be associated with HIV replication in the Central Nervous System (CNS), this study aimed to assess plasma CNS tissue markers in HTE versus controls. Methods HTE…

607 – CSF Memory B Cells Exhibit Distinct Molecular Footprints in Treated PWH

Background Neutralizing B cell responses are critical for sustained viral control in people with HIV (PWH). However, whether B cell alterations contribute to viral persistence in the central nervous system is unknown. To address this gap, we profiled the single B cell receptor (BCR) repertoire and transcriptomes in cerebrospinal fluid (CSF) and blood of PWH…

587 – HIV Transcriptional Regulation in the CNS of ART-Suppressed People With HIV

Background We and others have previously demonstrated that intact, transcriptionally competent HIV genomes persist within the brain of virally suppressed people with HIV (PWH). Long terminal repeats (LTRs) isolated from the brain of non-virally suppressed PWH are genetically distinct from those isolated in matched peripheral tissue and have a reduced responsiveness to select latency reversing…

585 – HIV Reservoir in Jejunum Exhibits Distinct Phenotypic Features and Evokes Innate Cell Redistribution

Background The human gut has a high burden of HIV, but little is known about the phenotypes of HIV reservoir cells at this site or the influence of the local microenvironment. Here, we used standard and 40-parameter multiplexed ion beam imaging by time of flight (MIBI-TOF) microscopy to study the HIV reservoir and their associated environments…

628 – Unmasking the Independent Role of CSF HIV RNA Dynamics by Single Copy Assay in Neurobiotypes

Background In the current study, we test whether low level HIV replication is important in the pathogenesis of neurocognitive and neuroimaging biotypes, and independent of comorbidity and legacy effects. Methods 43 virally-suppressed clinically stable men with HIV (age 53±14 years, plasma and CSF <20-50 cp/mL) were included. Neurocognition, CSF neopterin, plasma and CSF HIV RNA…

528 – MLN4924 Reduces HIV Transcription, Cell Survival, and HIV Infectivity After Latency Reversal In Vitro

Background Neddylation is essential for post-translational regulation of many cellular processes, including transcription and protein degradation. The NEDD8-activating enzyme inhibitor MLN4924 (MLN) can block degradation of HIV restriction factor APOBEC3G (A3G) in newly infected cells. Here we show that inhibiting neddylation via MLN reduces HIV reactivation from latency after treatment with latency reversing agents (LRAs).…
