چکیده انگلیسی
Tissue kallikrein (TK) was previously shown to take most of its biological effects through bradykinin receptors. In this study, we assumed that TK mediated neurite outgrowth was independent of bradykinin receptors. To test the hypothesis, we investigated TK-induced neurite outgrowth and its signaling mechanisms in cultured primary neurons and human SH-SY5Y cells. We found that TK stimulation could increase the number of processes and mean process length of primary neurons, which were blocked by epidermal growth factor receptor (EGFR) inhibitor or down-regulation, small interfering RNA for flotillin-2 and extracellular signal-regulated kinase (ERK) 1/2 inhibitor. Moreover, TK-induced neurite outgrowth was associated with EGFR and ERK1/2 activation, which were inhibited by EGFR antagonist or RNA interference and flotillin-2 knockdown. Interestingly, inhibition of bradykinin receptors had no significant effects on EGFR and ERK1/2 phosphorylation. In the present research, our data also suggested that EGFR and flotillin-2 formed constitutive complex that translocated to around the nuclei in the TK stimulation. In sum, our findings provided evidence that TK could promote neurite outgrowth via EGFR, flotillin-2 and ERK1/2 signaling pathway in vitro.
