Researchers at Baylor College of Medicine, the University of Michigan, and collaborating institutions working with animal models of graft-versus-host disease reported in Immunity that alterations in the gut microbiome are connected to an increase in the oxygen levels in the intestine that follows immune-mediated intestinal damage. Pharmacologically reducing intestinal oxygen levels alleviated the microbial imbalance and reduced the severity of the intestinal disease.
A study published in the journal Immunity reveals a mechanism that allows triple negative breast cancer to develop resistance to therapy. Researchers at Baylor College of Medicine showed that lipid accumulation in tumor cells and nearby immune cells promotes immune suppression, but disrupting lipid formulation reverses treatment resistance and the immunosuppressive microenvironment.
