And with a great stroke association following up on promising
research this would be looked at to create stroke protocols for stroke repair. We
need to repair 12 km (7.5 miles) of connections for each minute of infarct. But fucking nothing will be done with this because we have NO stroke leadership and NO stroke strategy. You're screwed because all the stroke medical professionals in the world can't get their act together and solve all the problems in stroke.
New Material to Help Repair Brain Tissue Damaged by Stroke
One of the reasons why strokes are so devastating is that brain
tissue does not exhibit the same healing mechanisms as other tissues
that repair themselves quickly. Integrin proteins are responsible for
some of the healing processes, including getting new cells to move and
having them adhere to the extracellular matrix, and these are not
strongly present within damaged brain tissue. In order to get the brain
to heal itself better than on its own, a team led by UCLA scientists has
come up with a material that is similar to the extracellular matrix and
that promotes the activity of integrin to heal nearby tissues.The hydrogel-based material, which has already been successfully tried in post-stroke mice, features vascular endothelial growth factor and a molecule that promotes α3/α5β1 integrin binding, which the researchers have shown leads to much stronger and less leaky blood vessels than a molecule that promotes αvβ3 integrin binding.
The studied mice demonstrated considerable repair of their brain tissues following a stroke, which bodes well that humans will also react similarly to this new approach to stroke care. Hopefully clinical trials will soon be underway to validate the new technology.
