Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Abstract

Abstract Image

mRNA-loaded lipid nanoparticles (mRNA-LNPs) show great therapeutic potential, but their use in central nervous system (CNS) disorders is limited by poor blood–brain barrier (BBB) penetration. Intranasal (IN) administration can bypass the BBB via olfactory/trigeminal pathways, enabling direct brain targeting and rapid screening of brain-specific lipid nanoparticles (LNPs). Using a peptide-based ionizable lipid platform, we systematically evaluated how LNP surface charge affects IN brain delivery and found that positively charged mRNA-LNPs produced superior brain transfection. Iterative in vivo screening yielded an intranasal brain-targeting LNP (INBT LNP) that efficiently traverses the olfactory and trigeminal nerves, drives brain-specific mRNA expression, and minimizes off-target expression in peripheral organs. Co-delivery of mRNAs encoding brain-derived neurotrophic factor (BDNF) and interleukin-10 (IL-10) using INBT LNPs significantly reduced neuroinflammation, inhibited neuronal death, and improved cognition in a repetitive mild traumatic brain injury (rmTBI) mouse model. Overall, this work establishes a noninvasive, patient-compliant, intranasal mRNA-LNP platform for brain delivery, offering a promising therapeutic strategy for TBI and other CNS disorders.
