摘要：

Neuronal death and neuroinflammation has been considered as the main contributors to the progression and deterioration of HFMD caused by CV-A10. Necroptosis is a lytic and inflammatory form of cell death that plays a crucial role in viral pathogenicity. Herein, our study showed that CV-A10-infected SH-SY5Y cells induced necroptosis via activating RIPK3-depedent pathway, but not requiring RIPK1, and meanwhile triggered the release of inflammatory cytokines. Moreover, RIPK3-mediated necroptosis was also involved in virus production, which did not require RIPK1 either. Finally, it was further verified that TLR3 drove RIPK3-mediated cell death by sensing CV-A10 RNA and activating RIPK3. Collectively, our study demonstrated that initiation of necroptosis in SH-SY5Y cells induced by CV-A10 accelerated the formation of inflammatory response and promoted virus replication through triggering a TLR3-initiated RIPK3-dependent pathway of necroptosis, which advanced the current understanding of necroptosis for the neuropathogenesis of CV-A10 infection.Copyright © 2025 Elsevier Ltd.
