Patients who suffer an acute ischaemic stroke, the most common form of a stroke where the blood supply to the brain is blocked, will be given the anti-clotting drug in addition to other medications during the first critical hours. We now need to test it to see if it has a positive impact on people who have suffered a stroke,' Prof Jackson said. 'We know from Phase 1 trials in healthy people that this antiplatelet drug is safe and well tolerated. The new drug will be trialled at stroke units across the country including at the Royal Prince Alfred, Prince of Wales, John Hunter Hospital in Newcastle, Royal Adelaide and Royal Melbourne Hospital. 'It does this without an added risk of bleeding, and we know bleeding leads to more strokes so this drug may help reduce risk of another stroke.' 'It has the ability to attack different components of the blood clot than tPA alone and the new combination therapy looks very promising in experimental models. 'In our preclinical models, we have shown that our anti-clotting drug, when combined with tPA, not only dissolves a blood clot from a stroke more effectively than tPA alone but it can stop the clot from reforming,' Prof Jackson said.

Rapamycin can reduce Rho-A mediated cytoskeletal rearrangements by inhibiting mTOR s6K (hypothetical).However the drug is ineffective for many patients and researchers are working to identify new anti-clotting methods that reduce stroke injury. Rapamycin increases autophagy leading to enhanced cell viability and tight junction expression (based on cell culture and animal studies). Rapamycin can increase eNOS activity and improves CBF in Alzheimer's Disease (AD) mouse models. On Friday, American pharmaceutical giant Merck announced that new data from clinical trials of its Molnupiravir drug showed a reduced risk of hospitalization or death from COVID by up to 50. Excess calcium entry into the endothelial cell leads to cytoskeletal re-arrangements by myosin light chain phosporylation and stress fibre formation leading to BBB opening.

Endothelial cells: Stroke/hypoxia can cause reduced CBF, endothelial cell death and tight junction breakdown. Rapamycin can reduce MMP-9 expression following stroke (shown in animal models). Rapamycin may reduce constriction by RhoA-GTP (hypothetical). Pericyte: Stroke/hypoxia causes pericyte constriction and MMP-9 release (animal and cell culture). Rapamycin can potentially reduce the retraction of astrocytic endfeet and improve BBB permeability by inhibiting RhoA-GTP (hypothetical). Rapamycin treatment stops transition from cytotropic to cytotoxic phenotype in cell culture. Astrocyte: Stroke/hypoxia causes conversion of astrocytes from cytotropic to cytotoxic driven by mTOR and retraction of astrocytes from the BBB driven by Rho-GTP. There is significant potential in applying this old drug in new ways to improve functional outcomes for patients after stroke. Suggested neurovascular effects of rapamycin. This review highlights the potential use of rapamycin as a multimodal therapy, acting on the blood-brain barrier, cerebral blood flow and inflammation, as well as directly on neurons. Ischemic stroke cerebral blood flow inflammation mTOR rapamycin. This review highlights the potential use of rapamycin as a multimodal therapy, acting on the blood-brain barrier, cerebral blood flow and inflammation, as well as directly on neurons. Recent evidence suggests that rapamycin is neuroprotective, not only via neuronal autophagy but also through its broader effects on other cells of the neurovascular unit. A new anti-clotting drug could significantly improve outcomes for stroke patients, with promising signs of improved blood flow to the brain to reduce instances of death and disability. A new anti-clotting drug that shows promise for stroke patients will be trialled across the country.

One such therapy already in use in transplant medicine is the mTOR inhibitor rapamycin. New drug 'very promising' for stroke care. Inducing this effect pharmacologically could improve clinical outcomes. Endogenous neuroprotection has been shown to be, in part, due to changes in mTOR signalling pathways and the instigation of productive autophagy. A therapy that could extend this window by protecting neurons may improve outcome. The window for the administration of these therapies is narrow, hampered by the necessity of rapidly imaging patients.

Currently, proven effective therapies have been limited to thrombolysis and thrombectomy. The significant morbidity that accompanies stroke makes it one of the world's most devastating neurological disorders.
