In fact, a high abundance of intratumor Lachnoclostridium was positively linked to the expression of chemokines C-C motif chemokine ligand 5 (CCL5), C-X-C motif chemokine ligand 10 (CXCL10), CXC motif chemokine ligand 9 (CXCL9), which, together, were associated with significantly increased patient survival and reduced mortality in cutaneous melanoma. The gene discussed is CCL5; the disease is cutaneous melanoma.
