Methionine enkephalin upregulates the immune function of RAW264.7 cells to inhibit the infection of Nelson Bay orthoreoviruses.

ABSTRACT: Preliminary research has found that MENK can upregulate the antiviral state of macrophages to inhibit influenza virus infection. To further study the immunomodulatory mechanism of MENK in macrophages against reovirus, we used RNA-Seq technology to analyze the genomic changes between macrophages infected with Nelson Bay orthoreoviruses (Miyazaki) after MENK pretreatment and those infected with Miyazaki alone. A total of 3,624 genes were screened, with 1,817 genes upregulated and 1,447 genes downregulated. Differentially expressed genes were mainly enriched in the cell cycle (ko04110), FoxO signaling pathway (ko04068), cell adhesion molecules (ko04514), Fc receptor-mediated endocytosis (ko04666), and antigen processing and presentation pathways (ko04612). Key genes such as IL6ST, TNFR2, CCL2
