To determine whether γδ T cells could potentially infiltrate prostate tumors, we analyzed the SU2C/PCF dataset that contained metastatic bone and soft tissue tumor biopsies from 118 mCRPC individuals (24) to measure expression levels of 14 TCR-γ genes (TRGV9, TRGV10, TRGVB, TRGV7, TRGV4, TRGV5, TRGV2, TRGV3, TRGVA, TRGV6, TRGV5P, TRGV11, TRGV1, and TRGV8). This evidence concerns the gene TRGV4 and neoplasm.
