We’re excited to see CureAlz-supported research continuing to shed light on how exercise benefits the brain. Dr. Christiane Wrann’s earlier work demonstrated that the hormone irisin, released from muscles during physical activity, plays a pivotal role in brain health by potentially mitigating a hallmark feature of Alzheimer's disease—the accumulation of amyloid beta plaques.
In the new study led by Dr. Wrann, irisin once again emerged as a potential neuroprotective factor—this time in a preclinical model of multiple sclerosis, in which it reduced symptoms and preserved neurons and synapses.
These findings reinforce a powerful idea: the biology of exercise may unlock new therapeutic pathways across neurodegenerative diseases. We’re proud to support research that brings us closer to treatments that protect the brain—not just manage disease.

Exercise-mediated neuroprotection in a mouse model of multiple sclerosis is reduced in mice lacking the irisin-encoding gene, Fndc5, and can be recapitulated by peripheral administration of irisin.
