A small molecule for stroke therapy
Better therapies for motor impairments after stroke are greatly needed. In mice and nonhuman primates, Abe et al.
found that edonerpic maleate enhanced synaptic plasticity and
functional recovery after a traumatic insult to the brain (see the
Perspective by Rumpel). This recovery of motor function was accompanied
by functional reorganization of the cortex.
Abstract
Brain
damage such as stroke is a devastating neurological condition that may
severely compromise patient quality of life. No effective
medication-mediated intervention to accelerate rehabilitation has been
established. We found that a small compound, edonerpic maleate,
facilitated experience-driven synaptic glutamate AMPA
(α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic-acid) receptor
delivery and resulted in the acceleration of motor function recovery
after motor cortex cryoinjury in mice in a training-dependent manner
through cortical reorganization. Edonerpic bound to
collapsin-response-mediator-protein 2 (CRMP2) and failed to augment
recovery in CRMP2-deficient mice. Edonerpic maleate enhanced motor
function recovery from internal capsule hemorrhage in nonhuman primates.
Thus, edonerpic maleate, a neural plasticity enhancer, could be a
clinically potent small compound with which to accelerate rehabilitation
after brain damage.
