This article discusses neurological and psychiatric disorders associated with SARS-CoV-2 virus infection, taking into account biological pathomechanisms and psychosocial factors. The long COVID-19 along with the \"brain fog\" phenomenon were considered in the study. The purpose of the study is to analyse and discuss the available information from the scientific literature on the possible association between SARS-CoV-2 virus infection and the occurrence of neuropsychiatric disorders with different degrees of severity and temporal correlation. To discuss the correlation of COVID-19 with the occurrence of neuropsychiatric disorders, a systematic literature review was conducted using the following databases: PubMed, Elsevier and Google Scholar. The following keywords were used when searching the materials used: \"neuropsychiatric disorders\", \"COVID-19\", \"SARS-CoV-2\", \"NeuroCOVID\", \"cytokine storm\" and \"long COVID-19\". Focusing on the characteristics of the materials and methods used, as well as the results obtained and conclusions reached in each article, 164 publications of research, meta-analysis, review and case reports were included in the study. Neuropsychiatric disorders resulting from SARS-CoV-2 virus infection are multifactorial in nature. The main elements responsible for the varied pattern of symptoms include direct and indirect central nervous system effects of the disease, individual patient conditions, psychosocial factors, severity of immune responses and severity of infection. The neuropsychiatric effects of SARS-CoV-2 infection can be divided into symptoms directly related to the neurological and psychiatric zones and mixed disorders.</p>","PeriodicalId":16665,"journal":{"name":"Journal of NeuroVirology","volume":" ","pages":"116-130"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143795681","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}

Aim of this study is to evaluate clinical course of PLWH affected by PML treated with pembrolizumab. We report four consecutive PLWH with clinical and radiological evidence of PML and JCV-DNA detection in cerebrospinal fluid (CSF). Pembrolizumab was administered to all four PLWH alongside cART. Radiological and laboratory follow-up were performed at the end of the medical protocol. Clinically, 3 out of 4 PLWH showed an improvement in neurological deficits, partially reacquiring the lost functions, and they are alive at 3.5 years, 14 months, and 9 months, respectively; the fourth patient died shortly after treatment due to worsening respiratory conditions. In all the PLWH completing treatment, a decrease of about 80-90% of the specific PD-1 activity was observed. Prolonged survival and stabilization of radiological findings have been observed, along with clinical improvement and partial recovery of acquired deficits in 3 out of 4 PLWH.

In the present study, we demonstrated that OLR1 expression was upregulated during ectopic expression of Tat or soluble Tat stimulus in BV-2 microglial cells. Moreover, OLR1 signaling was proved to facilitate Tat-triggered inflammatory response and alleviated the microglia-derived conditioned media-mediated HT-22 neural cells apoptosis in a NF-κB-dependent manner. Conversely, Tat augmented OLR1 expression via NF-κB signaling pathway. Finally, in mouse models, we determined that silencing of OLR1 significantly ameliorated Tat‑induced neuroinflammation and hippocampal neuronal death.

The batIFIT5 was expressed in HEK-293T cells, which were infected with RABV genetic lineages isolated from Eptesicus furinalis (IP 964/06) and Tadarida brasiliensis (IP 3214/19), at varying infectious doses (pure, 100, 10, and 1). Direct immunofluorescence was performed to assess the effect of batIFIT5 on virus replication through the counting of fluorescent foci. Subsequently, after the expression of batIFIT5, 1 MOI was selected and used to evaluate the potential antiviral effect. Immunofluorescence was performed 24 and 48 h after infection. As a result, the viral concentration remained similar in the presence of batIFIT5 across distinct infectious doses.
