Spliceosomal GTPase Eftud2 regulates microglial activation and polarization
Elongation factor Tu GTP binding domain protein 2 (Eftud2) is a spliceosomal GTPase that serves as an innate immune modulator restricting virus infection. Microglia are the resident innate immune cells and the key players of immune response in the central nervous system. However, the role of Eftud2...

description | Elongation factor Tu GTP binding domain protein 2 (Eftud2) is a spliceosomal GTPase that serves as an innate immune modulator restricting virus infection. Microglia are the resident innate immune cells and the key players of immune response in the central nervous system. However, the role of Eftud2 in microglia has not been reported. In this study, we performed immunofluorescent staining and western blot assay and found that Eftud2 was upregulated in microglia of a 5xFAD transgenic mouse model of Alzheimer’s disease. Next, we generated an inducible microglia-specific Eftud2 conditional knockout mouse line (CX3CR1-CreER; Eftud2f/f cKO) via Cre/loxP recombination and found that Eftud2 deficiency resulted in abnormal proliferation and promoted anti-inflammatory phenotype activation of microglia. Furthermore, we knocked down Eftud2 in BV2 microglia with siRNA specifically targeting Eftud2 and found that Eftud2-mediated regulation of microglial proinflammatory/anti-inflammatory phenotype activation in response to inflammation might be dependent on the NF-κB signaling pathway. Our findings suggest that Eftud2 plays a key role in regulating microglial polarization and homeostasis possibly through the NF-κB signaling pathway. |
