Moreover, a cohort study in melanoma tissues revealed negative associations between intratumoral members of the genera Algibacter and Epilithonimonas and CD8+ T cell infiltration, while the Algibacter genus was also negatively correlated with overexpression of the chemokines CXCL9, CXCL10 and CCL5 [114]. This evidence concerns the gene CXCL9 and melanoma.
