Latest Patents

Bernard Payrastre holds a patent for the "Use of PI3KC2B inhibitors for the preservation of vascular endothelial cell barrier integrity." This invention addresses the critical issue of ischemia, a condition characterized by reduced blood flow and oxygen to an organ. The patent highlights the importance of re-establishing blood flow and re-oxygenation after an ischemic episode to limit irreversible damage. However, it also acknowledges the potential damaging consequences of reperfusion, such as increased vascular permeability, which contributes to edema and tissue damage. Payrastre's research demonstrates that genetic inhibition of PI3K-C2β reduces cerebral infarction in two ischemia/reperfusion models and improves neurological outcomes. This genetic inhibition stabilizes the blood-brain barrier after ischemic stroke and reduces inflammation. The invention provides a method for preserving vascular endothelial cell barrier integrity in patients by administering a therapeutically effective amount of a PI3KC2β inhibitor.
