[...] a worldwide collaboration involving more than 40 scientists and three hospitals led by researchers at Sanford Burnham Prebys has demonstrated a causal link between the gut microbiome and the immune system's ability to fight cancer. Together, the researchers identified a cocktail of 11 bacterial strains that activated the immune system and slowed the growth of melanoma in mice.
[...] Transferring these 11 bacterial strains to regular mice that lack intestinal bacteria (germ-free) induced anti-tumor immune response and slowed tumor growth.
To confirm that the results were relevant in human disease, the scientists obtained tissue samples from three cohorts of people with metastatic melanoma who subsequently received checkpoint inhibitor treatment. Indeed, reduced expression of UPR components (sXBP1, ATF4 and BiP) correlated with responsiveness to treatment, suggesting that there are potentially predictive biomarkers for the selection of patients who should receive immune checkpoint therapy.
