Metabolites released by the gut microbiota may influence host metabolism and immunity. We have tested the hypothesis that inulin-type fructans (ITF), by promoting microbial production of short-chain fatty acids (SCFA), influence cancer cell proliferation outside the gut. Mice transplanted with

The recent global resurgence of arthritogenic alphaviruses, in particular chikungunya virus (CHIKV), highlights an urgent need for the development of therapeutic intervention strategies. While there has been significant progress in defining the pathophysiology of alphaviral disease, relatively little is known
