Good morning all! Today’s digest includes two articles discussing the role of the local tissue microbiome in cancer. In the first, Zhu et al. explore the relationship between the intratumor microbiome, immune cell infiltration, and patient survival in the context of melanoma. The second study by Wilkie et al. examines how lipopolysaccharide produced by the commensal breast microbiota impacts cancer growth.

Additionally, there is a paper by Radojević et al. in which the authors found an association between the fecal microbiota and immunogenicity of peripheral blood monocyte-derived dendritic cells in healthy donors; a study by Kim et al. showing that diet and microbiome derived amino acids impact gut enterocyte communication with the brain in Drosophila; and a paper by Tandon et al. investigating the impact of the reciprocal transplantation of water from the surface and bottom of lakes with different trophic states on microbial community composition and function.
