Science Translational Medicine: Infection Could Help Patients' Immune Systems Tolerate Liver Transplant

Viruses aren't typically known for the good things they can do, but a new study reports that a history of hepatitis C infection in liver transplant patients actually restrains the anti-transplant immune responses some patients experience.In this way, the infection by the virus helps the body tolerate the new organ and may prevent rejection of the transplant. The research appears in the 25 June issue of Science Translational Medicine.

Science Translational Medicine: Transplant From Pigs Helps Regrow Human Muscle

People who have lost large amounts of muscle from traumatic accidents or military wounds can regrow these muscles with the help of a new procedure, researchers report in the 30 April issue of Science Translational Medicine. The technique, developed by Stephen Badylak and Brian Sicari and colleagues at the University of Pittsburgh, uses an implanted biological scaffold made of extracellular matrix (ECM) from pigs to coax a person's own stem cells into becoming muscle cells. The extracellular matrix is a structure that in animals is made up primarily of proteins and carbohydrates. The matrix surrounds cells and gives them a nourishing environment. . .
