is a highly contagious pathogen causing porcine enzootic pneumonia, which elicits prolonged inflammatory response modulated by pattern recognition receptors (PRRs). Although significant advances have been achieved in understanding the Toll-Like receptors that recognize , the role of nucleotide-binding oligomerization domain 1 (NOD1) in infected cells remains poorly understood. This study revealed that activates the NOD1-RIP2 pathway and is co-localized with host NOD1 during infection. siRNA knockdown of NOD1 significantly impaired the TRIF and MYD88 pathway and blocked the activation of TNF-α. In contrast, NOD1 overexpression significantly suppressed proliferation. Furthermore, we for the first time investigated the interaction between mhp390 and NOD1 receptor, and the results suggested that mhp390 and NOD1 are possibly involved in the recognition of These findings may improve our understanding of the interaction between PRRs and and the function of NOD1 in host defense against infection.

The primary cause of viral encephalitis (VE) is invasion of the central nervous system (CNS) by the virus, which leads to neuroinflammation and poses a significant threat to global public health. Microglia, as CNS-resident macrophages, play a crucial role in neuroinflammation and are often identified as the preferred target for the prevention or treatment of VE. In this study, we used pseudorabies virus (PRV)-induced VE in mice and pigs as a model to investigate the regulation of microglial responses during viral encephalitis and explored the mechanism of microglial activation.

The role of innate receptors in initiating the early inflammatory response to helminth larval stages in affected tissues during their life cycle within the host remains poorly understood. Given its pivotal role in detecting microbial elements and eliciting immune responses, exploring the NOD1 receptor could offer crucial insights into immune responses to parasitic infections. By using the larval ascariasis model, the acute model for early Ascaris sp.
