CXCL5 and colon adenocarcinoma: CXCL5 expression is characteristic of colon adenocarcinoma (Chen et al, 2019; Situ et al, 2022; Lin et al, 2021) and colitis (Keates et al, 1997; Z’Graggen et al, 1997; Rieder et al, 2001), but CXCL5+ cells are also occasionally found scattered in the healthy colon (Z’Graggen et al, 1997), indicating highly localized induction of this cytokine.
