  • Publication number: 20220098594
    Abstract: Described herein are compositions and methods for modulating cellular senescence of a cell or induction of the senescence-associated secretory phenotype (SASP) in a cell. The methods generally comprise modulating the level or activity of IRE1a as a mean to control cellular senescence and induction of the SASP. Also described are methods for treating and preventing ocular vascular diseases comprising contacting cells in an eye of a subject with a biguanide compound and ophthalmic compositions comprising a biguanide compound.

  • Patent number: 11058575
    Abstract: There is described a method for delivering exogenous biomolecules into an eye. The method generally has the steps of injecting, into a region of the eye, a mixture having a plurality of exogenous biomolecules and a plurality of plasmonic structures, the plasmonic structures having a plasmonic resonance wavelength, the plasmonic structures adjoining membranes of target cells in said region due to said injecting; and irradiating said region of said eye with a laser beam having a wavelength being offset to said plasmonic resonance wavelength, said irradiating causing the plasmonic structures to form pores in said membranes of said target cells, allowing at least some of the exogenous biomolecules to be delivered into the target cells via said pores.
