Abstract: This disclosure provides improved lipid-based compositions, including lipid nanoparticle compositions, and methods of use thereof for delivering nucleic acids in vivo. These compositions have reduced immune activation resulting in accelerated blood clearance and/or anti-drug antibodies and they have an improved toxicity profile and therapeutic index in vivo.

Abstract: The present invention provides compositions comprising amiloride amino acid and peptide conjugates. Efficient methods are also provided for administering the compositions for treating cancer and for delivering an amiloride conjugate into cancer cells in a subject in need thereof.

Abstract: The present invention relates to isolated 18-mer peptides corresponding to amino acid residues 369-386 of human plasminogen activator inhibitor 1 (PAI-1) and fragments thereof, compositions that include such peptides, and uses of such compositions for treating thromboembolic diseases and pathological conditions associated with neurological damage.

Abstract: The present invention relates to recombinant chimeric proteins comprising a surfactant protein precursor N-terminally fused to a plasminogen activator or comprising a mature surfactant protein N-terminally or C-terminally fused to a plasminogen activator. The invention is also directed to the corresponding nucleic acid molecules encoding such fusion proteins as well as to a method for their production. The invention further refers to a pharmaceutical composition comprising such a fusion protein and to pharmacological uses of an inventive fusion protein for the prevention and/or treatment of inflammatory and interstitial lung diseases.

Abstract: Described are methods of modulating stem/progenitor cell recruitment involving molecules that agonize the formation of plasmin stimulating the recruitment of stem/progenitor cells, including hematopoietic and endothelial precursor cells. Conversely, antagonists of plasmin can inhibit recruitment of the stem cells. In addition, the identification of the uPA receptor (uPAR) as a retention signal for stem cells in their niche suggests a novel method for increased engraftment and isolation of multipotent stem cells.

Abstract: The invention concerns the use of inhibitors of the urokinase type of plasminogen activator (uPA) appearing in the anterior segment of the eye, for the treatment and prevention of corneal ulcers and other disorders. The invention further concerns pharmaceutical compositions, comprising inhibitors of uPA, preferably eye drops and eye ointments. The pharmaceutical compositions according to the invention preferably comprise PAI-2 protein or a derivative thereof retaining uPA-inhibiting capacity, or a tripeptide aldehyde inhibitor, preferably the D-Phe-Pro-Arg-aldehyde (Ald-1). The PAI-2 protein, used according to the invention, is preferably produced through bacterial expression, as a fusion protein.

Abstract: This application describes methods of treatment involving a protease for activating the blood clotting factor VII, which (a) activates blood clotting factor VII, (b) is inhibited by the presence of aprotinin, (c) is increased in its activity by the presence of at least one of the following: calcium ions, heparin, or heparin related substances, and (d) in SDS-PAGE, on subsequent staining in the non-reduced state, has one or more bands in the molecular weight range from 50 to 75 kDa, and in the reduced state has a band at 40 to 55 kDa and one or more bands in the molecular weight range from 10 to 35 kDa, and a band, which corresponds to a proenzyme, in the molecular weight range from 60 to 65 kDa.
