C. diff captures blood cell cofactor to build defensive shield

Vanderbilt University Medical Center scientists have identified a C. diff protein system that senses and captures heme (part of hemoglobin) to build a protective shield that fends off threats from our immune system and antibiotics.

Protecting the injured kidney

Leslie Gewin and colleagues have upended conventional dogma about Wnt/beta-catenin signaling in the kidney, finding that it protects against chronic kidney disease rather than promoting it.
