David Esteban, Associate Professor of Biology, received one of nine research grants made by the Patient-Led Research Collaborative to fund high-impact projects that seek to understand the causes, diagnostics, and treatments of Long COVID. His funded project, entitled “Microbial metabolites as disease-modifying factors in Long-COVID,” will investigate the production of, and response to, microbially derived AhR ligands in the microbiomes of people with Long COVID.
