摘要:
Provided are compositions and methods useful in regenerating damaged tissue, especially cardiac tissue, by delivering to the site of injury an miRNA that can reduce, for example, the expression of phosphatase and tensin homolog (PTEN). The compositions and methods of the disclosure may be generally applied to deliver an miRNA to a cell or tissue such as, but not limited to, a neuron, a smooth muscle cell, or a tumor cell. The compositions comprise a transmembrane carrier peptide conjugated, optionally by a linker, to an oligonucleotide complementary to an miRNA. The carrier peptide facilitates the entry of the miRNA into cells and for delivery to a tissue of an animal or human may be mixed with an extracellular matrix-derived hydrogel carrier.
摘要:
Protein kinase inhibitors and more specifically inhibitors of the protein kinase c-Jun amino terminal kinase are herein described. Additionally, JNK inhibitor sequences, chimeric peptides, nucleic acids encoding same as well as pharmaceutical compositions for treating pathophysiologies associated with JNK signaling are herein provided.

Plenty of SII3 (POSH) and INK-interacting protein 1 (JIP-1) function as a multi-protein scaffold network for TCR-mediated JNK1 activation in CD8+ T-cells. Disruption of the POSH/JIP-1 complex led to profound defects in the activation of JNK1, as well as deficient activation or induction of the transcription factors c-Jun, T-bet and Eomesodermin Furthermore, disruption of the POSH/JIP complex in CD8+T-cells resulted in impaired proliferation, decreased cytokine expression and the inability to control tumors. Collectively, these data identify a mechanism for the specific regulation of TCR-dependent JNK1 activation and function that is key for CD8+ T-cell responses. The disclosure describes a group of compounds that individually or in concert target a common set of biological pathways important in T cell function, activation of innate inflammation, ischemic reperfusion injury, HIV release and oncogenesis.
摘要:
The application provides data from a clinical trial of a PSD-95 inhibitor in subjects undergoing endovascular repair of an aneurysm in or otherwise affecting the CNS. The subjects were stratified by whether the aneurysm ruptured before performing the endovascular surgery. Rupture is associated with higher mortality or increased debilitation if a subject survives. The trial provided evidence of significant benefit in subjects with and without aneurysm rupture before endovascular was surgery performed. Surprisingly, the subjects benefiting most from treatment as judged both by pathology and neurocognitive outcome were those in which the aneurysm had ruptured causing a subarachnoid hemorrhage. These data constitute evidence that a PSD-95 inhibitor is beneficial not only in ischemic and hemorrhagic stroke but in forms of hemorrhage in or affecting the CNS, particularly, subarachnoid hemorrhage.
