LAMA3, LAMB3, and LAMC2 mRNA levels had a weak negative correlation with immunoinhibitory genes including ADORA2 and CD160, immunostimulatory genes including CXCL12, KLRK1, and TNFRSF14, and MHC molecules such as HLA-DPB1 in PAAD. This evidence concerns the gene HLA-DPB1 and pancreatic adenocarcinoma.
