Fig. 5From: MicroRNAs: emerging driver of cancer perineural invasionPrediction of PNI invasion pattern. MiRNAs constitutes a bridge of the crosstalk between tumor cells and stromal cells, including natural killer (NK) cells including regulatory T cells (Treg cells), tumor-associated macrophages (TAMs) and cancer-associated fibroblasts (CAFs), and regulates the process of PNI. How does miRNAs mediate PNI, through collective invasion, single cell invasion or both?Back to article page
