  • Patent number: 8846386
    Abstract: Disclosed herein are nucleic acid molecules comprising a nucleotide sequence of sVEGF-2, proteins encoded by those sequences and antibodies that bind to the protein. Also disclosed are methods for inhibiting or enhancing expression or activity of sVEGFR-2 and methods for inhibiting graft rejection, particularly cornea graph rejection. Also described are methods for inhibiting lymphangiogenesis and lymphatic endothelial cell proliferation by administering an effective amount of sVEGFR-2 and methods for treating lymphedema by inhibiting the activity of sVEGFR-2.

  • Patent number: 8778616
    Abstract: The results presented herein demonstrate the specific expression of CCR3 in CNV endothelial cells in humans with AMD, and despite the expression of its ligands, eotaxin-1, -2, and -3, neither eosinophils nor mast cells are present in human CNV. The genetic or pharmacological targeting of CCR3 or eotaxins as disclosed herein inhibited injury-induced CNV in mice. CNV suppression by CCR3 blockade was due to direct inhibition of endothelial cell proliferation, and was uncoupled from inflammation as it occurred in mice lacking eosinophils or mast cells and was independent of macrophage and neutrophil recruitment. CCR3 blockade was more effective at reducing CNV than vascular endothelial growth factor-A (VEGF-A) neutralization, which is currently in clinical use, and, unlike VEGF-A blockade, not toxic to the mouse retina. In vivo imaging with CCR3-targeting quantum dots located spontaneous CNV invisible to standard fluorescein angiography in mice before retinal invasion.

  • Publication number: 20140178309
    Abstract: A method of protecting a cell includes inhibiting an inflammasome, MyD88, IL-18, VDAC1, VDAC2, caspase-8, and/or NF?B of the cell. Administering an inhibitor of MyD88, IL-18, VDAC1, VDAC2, caspase-8, and/or NF?B can protect the cell from Alu-RNA-induced degeneration. Protecting a cell, such as an retinal pigment epithelium (RPE), can be therapeutically useful in the context of age-related macular degeneration and geographic atrophy.

  • Patent number: 8481508
    Abstract: Provided are methods and compositions for the treatment or prevention of macular degeneration or other diseases or disorders associated with activation of TLR3. Administration of double stranded RNAs having a length of 22 nucleotides or less treats or prevents macular degeneration or other diseases or disorders associated with activation of TLR3 due to the ability of the RNAs to bind to but not activate TLR3. Furthermore, all double stranded RNAs (both targeted and non-targeted) of 22 nucleotides or less in length can bind to but not activate TLR3 and thereby treat or prevent such conditions. Also provided of a method for increasing the specificity of a desire siRNA target knockdown, the method comprising administering an amount of a target siRNA sufficient to knockdown a target gene and an amount of a double stranded RNA of 22 nucleotides or less which prevents the target siRNA from activating TLR3.
