ObjectiveThis study aimed the role of the CCL5/CCR5 axis in the perineural invasion of salivary adenoid cystic carcinoma (SACC) cells.MethodsImmunohistochemical analysis and flow cytometric analysis were conducted to detect the expression of the chemokine receptor CCR5 in SACC cells. Enzyme linked immunosorbent assay (ELISA) was performed to determine the expression of CCL5 in the supernate of human nerve cells. The flow cytometric analysis was applied to observe the changes in F-actin in SACC-LM cells, which were pretreated with CCL5. To assess the effects of the CCL5/CCR5 axis on the migration and invasion of SACC-LM cells, we performed a scratch test and invasion assay under CCL5 stimulation.ResultsCCR5 was highly expressed in SACC cells. The concentration of CCL5 in the supernatant of human nerve cells was (359.2±15.8), (696.4±22.6) pg·mL-1. The CCL5/CCR5 axis promoted the migration and invasion of SACC-LM cells.ConclusionThe CCL5/CCR5 axis may be involved in the perineural invasion of SACC cells.
