چکیده

Herpes simplex virus 1 (HSV-1) is a common virus that can rarely invade the human central nervous system (CNS), causing devastating encephalitis. The permissiveness to HSV-1 of the various relevant cell types of the CNS, neurons, astrocytes, oligodendrocytes, and microglia cells, as well as their response to viral infection, has been extensively studied in humans and other animals. Nevertheless, human CNS cell-based models of anti-HSV-1 immunity are of particular importance, as responses to any given neurotropic virus may differ between humans and other animals. Human CNS neuron cell lines as well as primary human CNS neurons, astrocytes, and microglia cells cultured/isolated from embryos or cadavers, have enabled the study of cell-autonomous anti-HSV-1 immunity in vitro. However, the paucity of biological samples and their lack of purity have hindered progress in the field, which furthermore suffers from the absence of testable primary human oligodendrocytes. Recently, the authors have established a human induced pluripotent stem cells (hiPSCs)-based model of anti-HSV-1 immunity in neurons, oligodendrocyte precursor cells, astrocytes, and neural stem cells, which has widened the scope of possible in vitro studies while permitting in-depth explorations. This mini-review summarizes the available data on human primary and iPSC-derived CNS cells for anti-HSV-1 immunity. The hiPSC-mediated study of anti-viral immunity in both healthy individuals and patients with viral encephalitis will be a powerful tool in dissecting the disease pathogenesis of CNS infections with HSV-1 and other neurotropic viruses.

Herpes simplex virus-1 evasion of CD8+ T cell accumulation contributes to viral encephalitis.

Herpes simplex virus-1 (HSV-1) is the most common cause of sporadic viral encephalitis, which can be lethal or result in severe neurological defects even with antiviral therapy. While HSV-1 causes encephalitis in spite of HSV-1-specific humoral and cellular immunity, the mechanism by which HSV-1 evades the immune system in the central nervous system (CNS) remains unknown. Here we describe a str...

Complete ablation of tumor necrosis factor decreases the production of IgA, IgG, and IgM in experimental central nervous system tuberculosis

Objective(s): This study aimed to explore the contribution of tumor necrosis factor (TNF) in the recruitment of B-cell and secretion of immunoglobulins (Igs) during cerebral tuberculosis (TB).Materials and Methods: In this work, the contributing role of TNF in regulating Ig secretions was investigated by comparing wild type TNF (TNFf/f),...

Role for cell-mediated immunity in the resistance of mice to subcutaneous herpes simplex virus infection.

The role of cell-mediated immunity in the resistance of young adult mice to subcutaneous herpes simplex virus (HSV) type I infection was studied in mice receiving immunosuppressive doses of antilymphocyte sera (ALS) or antithymocyte sera (ATS). The effectiveness of these treatments to reduce cell-mediated responses was measured by their ability to prolong the life of allografts transplanted to ...

Innate lymphotoxin receptor mediated signaling promotes HSV-1 associated neuroinflammation and viral replication

Host anti-viral innate immunity plays important roles in the defense against HSV-1 infection. In this study, we find an unexpected role for innate LT/LIGHT signaling in promoting HSV-1 replication and virus induced inflammation in immunocompromised mice. Using a model of footpad HSV-1 infection in Rag1(-/-) mice, we observed that blocking LT/LIGHT signaling with LTβR-Ig could significantly dela...

Maternal Antiviral Immunoglobulin Accumulates in Neural Tissue of Neonates To Prevent HSV Neurological Disease

While antibody responses to neurovirulent pathogens are critical for clearance, the extent to which antibodies access the nervous system to ameliorate infection is poorly understood. In this study on herpes simplex virus 1 (HSV-1), we demonstrate that HSV-specific antibodies are present during HSV-1 latency in the nervous systems of both mice and humans. We show that antibody-secreting cells en...
