英文摘要 | Toll like receptor (TLR) signaling cascades are under precise regulations to ensure the proper immune responses during various pathogen invasions. The neuregulin receptor degradation protein-1 (Nrdp1) has been demonstrated to be a novel negative regulator of TLR signaling by targeting MyD88 to induce degradation in mammals. In the present study, an Nrdp1 homologue, CgNrdp1, was identified from the genome of Pacific oyster Crassostrea gigas. It contained an open reading frame encoding a polypeptide of 315 amino acids which shared high identities with other homologues from different species. There was a conserved RING domain in CgNrdp1, indicating the functional E3 ubiquitin ligase activity. The bacterially expressed recombinant CgNrdp1 and CgMyD88 showed much stronger affinity compared to control groups in the ELISA assay, showing the interacting ability between CgNrdp1 and CgMyD88. When CgMyD88 or HsMyD88 was co-transfected with CgNrdp1 into HEK293T cells, the luciferase activities of NF-kappa B were significantly decreased compared to those in MyD88 single-transfection groups, indicating the conserved negative regulating function of CgNrdp1 on the MyD88 induced TLR signaling. These results indicated that CgNrdp1 was a negative regulator of TLR signaling in oyster and the Nrdp1-MyD88 axis was functional and highly conserved from mollusks to mammals in the negative regulation of TLR signaling. |
