Ischemic stroke, caused by a blockage of blood flow to the brain, is a common cause of death and disability. Treatments are urgently needed to improve patient outcomes, because recovery currently depends largely on the timely injection of a blood clot-dissolving drug. Priorities for therapy include limiting inflammation at the ischemic site and rebuilding neuronal connections damaged by the stroke. However, a molecule that can achieve these therapeutic effects has remained elusive.
In a study to be published in Stroke, researchers from Osaka University provide new hope for patients. They have identified two proteins, R-spondin 3 (RSPO3) and LGR4, that trigger a cascade of reactions in cells (i.e., a signaling pathway) to reduce inflammation in the ischemic brain. RSPO3 and LGR4 also stimulate the growth of extensions from neurons, a process called neurite outgrowth.
