| Abstract: | Objective To explore the expression of Toll-like receptor family（TLRs）in mouse glioma cell line GL261 and effects of TLR2 activation on migration capacity of GL261 cells. Methods The expression of TLRs in GL261 was detected by qRT-PCR. Transwell migration assays were performed to determine the migration capacity of GL261 cells stimulated with Pam3CSK4, a TLR2 ligand. The change of migration capacity after silencing TLR2 in GL261 was examined by transwell assays. Results TLR2 of the TLRs family was highly expressed in GL261 cells. Pam3CSK4 stimulation enhanced migration capacity of GL261 cells was induced. Conclusion Triggering of TLR2 expressed by GL261 cell line enhanced its migration capacity, and the effect was reduced with down-regulation of TLR2. |
