In addition, species-specific differences exist in terms of TLR expression, regulation and function. These observations suggest that caution should be exercised in extrapolating the results of the innate antiviral activity of t-way between the species and cell types.
Viruses from several families preferred infecting CNS neurons, and magnitude of cell death mediated by neurotropic virus may be an important factor in the severity and clinical outcome of infection. Sun controls an effective antiviral innate neural response, which ones The replication of the virus can be generated by an adaptive immune response can be critical to irreversible loss of these cells, essentially to prevent critical. However, we have limited exposure to the PRR antiviral pathways that are active in neurons of the central nervous system. TLR3 expression in human neurons, it was reported that West Nile virus replication in cortical neurons is improved isolation of TLR3 � � Mice and neural precursor cells shore Respond to stimulation by poly proliferation and the formation of neurospheres in a manner dependent TLR3 Dependent.
In addition, studies of virus-mediated induction of type I IFN in the neurons of the central nervous system in vitro and in vivo is shown. In addition to antiviral putative functions, the PRR were brought pathways in neuronal development, neuronal regeneration and neuroinflammatory diseases. Taken together, these reports indicate that neurons in the central nervous system can PRR Verm Assets, which have different physiological functions k, But the full Ausma their activity t and downstream components, which are activated to mediate yet to be determined. In this report we use two global approaches and targeted way to PRR expression and activity of t in response to RLR and TLR ligands examined. We found that human neural cell-dependent Show Independent differentiation responses to selective stimulation, TLR3, TLR4, MDA5 and RIG-Imediated.
Furthermore, detailed genetic and pharmacological studies have shown that some neurons innate immune signaling pathways dependent Were ngig of PI3K activity t. These results show that human neural cells are immunologically active and possess specific and non-licensed PRR signaling pathways that may play a functional r The Protector in the pathogenesis of neurotropic viruses.
