Morphine Tolerance Pathway Identified in Mice
Morphine Tolerance Pathway Identified in Mice
David Adam | Sep 20, 2021
Prolonged exposure to morphine triggers cells in the spine to release signaling molecules that increase pain sensitivity and dull the relief of the drug. Blocking this activity could improve pain management.

Putative Exercise Hormone Irisin Boosts Mouse Brainpower
Sophie Fessl | Sep 10, 2021
Mice lacking irisin didn’t exhibit the cognition improvements that typically follow exercise, and in mouse models of Alzheimer’s disease, treatment with the hormone reduced cognitive decline.
