ABSTRACT
OBJECTIVE:
To explore the role of Erbin protein and nucleotide-binding oligomerization domain 2/receptor-interacting serine/threonine protein kinases (NOD2/RICK) in GTS-21 activating cholinergic anti-inflammatory pathway.METHODS:
Experiments were randomly divided into four groups normal control (NC) group, muramyl dipeptide (MDP) group, 10âµg/mL MDP, GTS-21 (GTS) group, 10âµg/mL MDP plus 50âµg/mL GTS-21 (α7 nAChRs agonist), Erbin shRNA interference (sh-Erbin) group sh-Erbin RNA plus 10âµg/mL MDP and 50âµg/mL GTS-21. We extract specimens at the point of 1, 6, and 24âh after stimulation of MDP in Raw264.7 macrophages.RESULTS:
After stimulation of MDP, the NLR2 mRNA, RICK and Erbin protein, nuclear factor (NF)-κB activity, the pro-inflammatory cytokines tumor necrosis factor (TNF)-α and HMGB1 were significantly increased in MDP group (Pâ<0.05). The expression peak of TNF-α is at 1 h. The peak of HMGB1 is at 24âh. Compared with MDP group, the NLR2 mRNA, RICK, NF-κB, TNF-α, and HMGB1 were significantly decreased, but the Erbin was increased in GTS group (Pâ<0.05). Compared with GTS group, the NLR2 mRNA, RICK, NF-κB, TNF-α, and HMGB1 increase in sh-Erbin group (Pâ<0.05).CONCLUSION:
GTS-21 could significantly inhibit MDP-induced pro-inflammatory cytokines responses via activating cholinergic anti-inflammatory pathway, and the Erbin might be the key negative regulatory protein in NLR2/RICK signal transduction.
