Medium spiny neurons (MSNs) in the nucleus accumbens core (NAcc), an integrator of cortical and thalamic input, have been implicated as a key structural locus for the pathogenesis of SUD. To date, however, how constitutive expression of HIV-1 viral proteins alters the development of MSNs in the NAcc has not been systematically evaluated. Methods An innovative ballistic labeling technique was utilized to examine MSNs in the NAcc, and associated dendritic spines, in HIV-1 transgenic (Tg) and control animals. First, a time-sequential longitudinal experimental design was implemented, whereby animals were sacrificed at 30-day intervals from postnatal day (PD) 30 to PD 180. Second, the therapeutic efficacy of S-Equol for HIV-1-associated synaptic dysfunction in MSNs was evaluated using a cross-sectional experimental design. Results Constitutive expression of HIV-1 viral proteins disrupted the development of MSNs, evidenced by alterations in neuritogenesis and synaptogenesis. Furthermore, age-related, progressive synaptodendritic alterations were observed in the patterning of dendritic branches and dendritic spines, as well as dendritic spine head diameter, in HIV-1 Tg, relative to control, animals. Treatment with S-Equol during the formative period, however, led to long-term enhancements in synaptic function (i.e., PD 180). Conclusions Developmental and progressive synaptodendritic alterations in MSNs induced by chronic HIV-1 viral protein exposure may underlie the increased propensity for pALHIV to develop SUD. Elucidating a potential neural mechanism underlying the unique vulnerability of pALHIV to SUD affords a fundamental opportunity for the evaluation of therapeutics.","PeriodicalId":74278,"journal":{"name":"NeuroImmune pharmacology and therapeutics","volume":"2 1","pages":"153 - 167"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49631413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods We exposed primary rat immature oligodendrocytes to HIV Tat and utilized various experimental techniques to assess its effects on oligodendrocytes maturation. We measured ROS levels, assessed lysosomal membrane potential, determined cathepsin D activity, and analyzed the expression of autophagy-related markers. Furthermore, we investigated the potential of ROS scavengers and lysosomal protectants to mitigate the damaging effects of HIV Tat on oligodendrocytes maturation. Results Exposure of primary rat immature oligodendrocytes to HIV Tat significantly increased ROS levels, indicating the induction of oxidative stress. This oxidative stress impaired lysosomal functioning, as evidenced by a substantial increase in lysosomal membrane potential and a decrease in cathepsin D activity. Compromised lysosomal function resulted in dysregulated autophagy, which was confirmed by increased expression of SQSTM1. However, the administration of ROS scavengers and lysosomal protectants effectively attenuated the detrimental effects of HIV Tat on oligodendrocytes maturation. Conclusions Our findings demonstrate that HIV Tat exposure induces oxidative stress, impairs lysosomal functioning, and dysregulates autophagy in oligodendrocytes. These molecular changes likely contribute to the altered maturation of oligodendrocytes observed in HIV-infected individuals. Understanding these underlying mechanisms provides valuable insights into the pathogenesis of HIV-associated neurocognitive disorders and highlights the potential of therapeutic strategies targeting ROS scavenging and lysosomal protection as adjunctive approaches for managing such complications in HIV +ve individuals.","PeriodicalId":74278,"journal":{"name":"NeuroImmune pharmacology and therapeutics","volume":"2 1","pages":"139 - 151"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46930059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
