We found a significant correlation between NOD2 mRNA and hBD2 (r = 46; P = 0.039), psoriasin (r = 0.67; P = 0.0016), SKALP/elafin (r = 0.65; P = 0.0026). In unstimulated, PAM-stimulated, and MDP-stimulated normal keratinocytes, NOD2, RIP2, CARL, and SKALP/elafin expression significantly (P < 0.05) increased from 6 h to 48 h. In unstimulated, PAM-stimulated, and MDP-stimulated HS keratinocytes, RIP2, CARL, and SKALP/elafin expression significantly (P < 0.05) declined from 6 h to 48 h. mRNA expression of HS keratinocytes at 6 h was significantly increased for NOD2 (unstimulated, PAM, MDP), CARL (unstimulated, PAM, MDP), and SALP/elafin (unstimulated, PAM) as compared to normal keratinocytes.We have shown for the first time that the NOD2 signalling is activated in HS and might contribute to the pathogenesis via induction of AMPs and activation of other pathways such as NFκB signalling. 000169037 536__ $$0G:(DE-HGF)POF4-311$$a311 - Zellbiologie und Tumorbiologie (POF4-311)$$cPOF4-311$$fPOF IV$$x0 000169037 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo01.inet.dkfz-heidelberg.de 000169037 7001_ $$aHessam, S.$$b1 000169037 7001_ $$aSkrygan, M.$$b2 000169037 7001_ $$aBakirtzi, M.$$b3 000169037 7001_ $$0P:(DE-He78)a9aa7740c4c6f243d651d9bd35ed7fdf$$aKasakovski, D.$$b4$$udkfz 000169037 7001_ $$aBechara, F.
