pathways that enable zebrafish to restore their tail fins. "The ability to regenerate body parts such as those that are damaged by injury or disease," said Dr. Randall Moon, professor of pharmacology at the University of Washington (UW), an investig...
Protein's effects essential for kidney-to-bladder urine transfer
...Immunobiology, the immune synapse is a specialized communication
structure created by two immune cells. According to the theory, this communication
activates immune cells to fight invaders. Swat had hypothesized that DLGH1 might help move structure...

Research yields new insights into the cause of diabetes
...e beta cells. But without the islet architecture, communication
among the beta cells breaks down and the cells fail to respond to glucose by secreting insulin. Thus, PERK-deficiency both hampers cell-to-cell signaling of glucose levels and greatly diminishes insulin production at the cellular level. The Penn St...
