This technology includes a transgenic reporter mouse that expresses a fluorescent protein called mt-Keima, to be used to detect and quantify in vivo mitophagy. This fluorescent protein was originally described by a group in Japan and shown to be able to measure both the general process of autophagy and mitophagy. We extended these results by creating a living animal so that we could get a measurement for in vivo mitophagy. Our results demonstrate that our mt-Keima mouse allows for a straightforward and practical way to quantify mitophagy in vivo.
This technology includes a generated polyclonal antibody in rabbit that detects the mitochondrial uniporter (MCU) protein. This antibody was created by immunizing rabbits with a synthesized sequence of the MCU protein and can be used to identify and quantify MCU protein in various tissues. The polyclonal nature of the antibody ensures it recognizes multiple epitopes on the MCU, enhancing detection reliability. This technology is crucial for understanding MCU's role in mitochondrial function and mammalian physiology.
Summary:
The National Eye Institute seeks research co-development partners and/or licensees for novel methods of cryopreserving cells, tissues, and organs via FOXO1 activation and other mechanisms.
The limited choice in cell types available for in vitro studies has become an obstacle in hibernation research.
Researchers at the National Eye Institute for the first time have successfully established iPSC line(s) from a mammalian hibernator, which can be potentially used to generate various cell types and tissue models for in-depth mechanistic studies of hibernation and coldness tolerance in vitro.
Researchers at the National Eye Institute (NEI) have discovered an invention describing a composition and method(s) of using such composition for preserving viability of cells, tissues, or organs at a low temperature (around 4ºC). Current cold storage solutions or methods for cells, tissues, and organs are suboptimal due to irreversible damage to cold-sensitive tissue or organ transplants that need a longer term of storage for facilitating clinical practices.
Approximately one-third of non-syndromic retinal dystrophies involve a defect in a ciliary protein. Non-syndromic retinal ciliopathies include retinitis pigmentosa, cone dystrophy, cone-rod dystrophy, macular dystrophy, and Leber-congenital amaurosis (LCA). Many CEP290-LCA patients also exhibit auditory and olfactory defects. Induced pluripotent stem cells (iPS) cells were derived from patients with LCA and unaffected relatives.
The National Eye Institute (NEI) seeks research collaborations and/or licensees for the use of these iPS cells.
The Huh-7 cell line underwent a detailed sub-cloning process to enhance its effectiveness for Hepatitis E Virus (HEV) infection studies. This involved diluting and culturing cells in 96-well plates until confluent monolayers formed, followed by selection and expansion of the most suitable cells. The sub-clone S10-3, derived from this process, was identified as the most efficient for transfection and infection by HEV.
This technology includes antibodies for TMC1 protein as a treatment for hearing loss. TMC1 is one of the common genes causing hereditary hearing loss. Our laboratory used synthetic peptides corresponding to the TMC1 protein to immunize rabbits. The resulting antisera were shown to bind to TMC1 protein expressed in heterologous expression systems. TMC1 protein is required for the transduction of sound into electrical impulses in inner ear sensory cells.
This technology includes a vaccine for lowering plasma triglycerides by inducing the formation of autoantibodies against either ANGPTL3 or ANGPTL4, which are inhibitors of Lipoprotein Lipase. This was done by conjugating synthetic peptides based on ANGPTL3 or ANGPTL4 to virus- like particles (VLPS). Injection of the vaccine in animal models was shown to induce the autoantibody against the target and to lower plasma triglycerides.
