  • Publication number: 20240425863
    Abstract: Ischemic conditions are a leading cause of death for both men and women, Ischemia, a condition characterized by reduced blood flow and oxygen to an organ. Re-establishment of blood flow, or reperfusion, and re-oxygenation of the affected area following an ischemic episode is critical to limit irreversible damage. However, reperfusion also associates potentially damaging consequences. For instance, increased vascular permeability is an important contributor to edema and tissue damage following ischemic events. Here the inventors shows that genetic inhibition of PI3K-C2? reduces cerebral infarction in two ischemic/reperfusion (I/R) models and improves neurological outcome. The genetic inhibition stabilizes the blood-brain barrier (BBB) after ischemic stroke and reduces inflammation.

  • Publication number: 20240366804
    Abstract: The present invention relates to novel biocompatible imaging particles comprising superparamagnetic iron oxide (SPIO) assembled into submicromiter-sized clusters within a biodegradable polycathecolamine or polyserotonine matrix, their synthesis and use in imaging techniques. These particles overcome the issues of toxicity and unreliable signal of the molecules from the prior art by providing similar contrast to that of the microparticles of iron oxide and rapidly disassemble into isolated SPIO particles once they reach the acidic lysosomal compartment of the MPS cells, thus enabling their digestion.

    Abstract: Ischemic conditions are a leading cause of death for both men and women. Ischemia, a condition characterized by reduced blood flow and oxygen to an organ. Re-establishment of blood flow, or reperfusion, and re-oxygenation of the affected area following an pot ischemic episode is critical to limit irreversible damage. However, reperfusion also associates potentially damaging consequences. For NI instance, increased vascular permeability is an important contributor to edema and tissue damage following ischemic events. Here the inventors shows that genetic inhibition of PI3K-C2? reduces cerebral infarction in two ischemia/reperfusion (UR) models and improves neurological outcome. The genetic inhibition stabilizes the blood-brain barrier (BBB) after ischemic stroke and reduces inflammation.

  • Patent number: 10239953
    Abstract: Disclosed herein is a bispecific inhibitor for use in treating thrombotic disorders, such as acute thrombotic disorders like stroke and thromboembolism. The bispecific inhibitor is based on monoclonal antibodies targeting TAFI and PAI-1, and shows efficacy in the presence or the absence of plasminogen activators such as tissue-type plasminogen activator (tPA).

  • Publication number: 20130058939
    Abstract: The invention relates to a protein or peptide consisting of a kringle protein or peptide and its use for the treatment of neurological or neurodegenerative disorders, in particular stroke. The invention relates also to an isolated antibody of fragment thereof which binds to the N-terminal domain of the NMDA receptor subunit NR1 (anti-NR1 antibody), whereas binding of the antibody or the fragment thereof prevents the cleavage of the extracellular domain of the NR1 subunit, or the fragment and its use for the treatment of neurological or neurodegenerative disorders, in particular stroke. The invention relates further to a pharmaceutical composition containing said kringle protein or peptide or anti-NR1 antibody.
