Now we just need more followup to get this into a protocol with defined diagnosis entry points. Which will never occur, unless YOU have the money to hire researchers to accomplish that. Our fucking failures of stroke associations will once again do nothing and let possible solutions slip away.

If you were to suffer a stroke,
would you want your brain to create more stem cells, replace the damaged
neurons or repair the broken blood vessels?
A new study led by Dr. Jing Wang shows that fine tuning a single molecular pathway may allow the brain to accomplish all three of these crucial tasks.
The study, published in Stem Cell Reports,
focuses on a pathway called aPKC-CBP. Dr. Wang and her colleagues found
that blocking this pathway early after a stroke can stimulate pericytes
(which wrap around blood vessels in the brain) to become stem cells.(Will this also stop pericytes from strangling neurons in the neuronal cascade of death?)
But if you permanently block the
pathway, it prevents the stem cells from becoming neurons and exhausts
the pericytes so they can’t help with blood vessel repair during the
chronic phase after a stroke. The paper thus suggests that the aPKC-CBP
pathway may need to be blocked at the early phase of a stroke, then
reactivated during the chronic phase of a stroke to get the optimal mix
of cells for stroke repair and functional recovery. While this research
was done in laboratory models, compounds that target the aPKC-CBP
pathway are already being tested in human clinical trials for other
conditions.

Funding: This research was possible because of generous donations to The Ottawa Hospital for Regenerative Medicine research.
The researchers also received support from the J.P. Bickell Foundation,
the Heart and Stroke Foundation (HSF), the HSF Canadian Partnership for
Stroke Recovery and the Canadian Institutes of Health Research.
