Recent research has revealed that the oral microbiota P. gingivalis can translocate to the pancreas and upregulate the expression of CXCR4 (C-X-C chemokine receptor type 4) in pancreatic cancer cells, a chemokine receptor capable of binding to the fimbriae of P. gingivalis [87]. The gene discussed is CXCR4; the disease is pancreatic neoplasm.
