Responses of CAFs after PDT:Production of TGFβ-1 induces a quiescent in tumor cells after PDT (47, 132–134)Induction of tumor progression (135)Secretion of IL1β, which induces tumor promotion (136)Production of CXCL12, which avoids the contact between T cells and cancer cells (137). The gene discussed is TGFB1; the disease is neoplasm.
