Multi-purpose protein regulates new protein synthesis and immune cell development
... Zhang says. "This is the first indication that a sensor
for protein folding in the endoplasmic reticulum can also signal the nucleus to regulate gene rearrangements required for B cell differentiation," Kaufman says. "It's a completely unexpected observation. Learning more about the IRE1 signaling pathway...
Light therapy may combat fungal infections, new evidence suggests
