Abstract: System for customizing visual field (VF) tests uses a machine learning model (15) trained on retina images (12A, 12C, 12D), including optical coherence tomography (OCT), optical coherence tomography angiography (OCTA), fundus, and/or fluorescein angiography images. In operation, in preparation for administering a specific VF test (13) to a patient, a retina image of the patient is submitted to the present machine model, which responds by synthesizing a VF prediction for the patient. The synthesized VF may be used to optimize the specific VF test prior to administering it to the patient.

Abstract: Methods and compositions for inhibiting or preventing neurodegeneration, specifically hippocampal, cortical, and/or retinal ganglion cell neurons (RGC), and degeneration and/or cell loss or treating related disorders and diseases comprising administering to a subject an effective amount of one or more lipoxin compounds and/or lipoxin analogues such that degeneration and/or cell loss of neurons is inhibited or prevented.

Abstract: Disclosed herein are methods of inducing neuronal outgrowth of a neuron. The methods comprise contacting the neuron with an agent that binds receptor protein tyrosine phosphatase ? (RPTP?), to thereby induce neuronal outgrowth of the neuron. The agent may induces clustering of RPTP? and/or inhibit binding of chondroitin sulfate proteoglycan (CSPG) to RPTP?. Examples of suitable agents are heparan sulfate proteoglycan, heparan sulfate, heparan sulfate oligosaccharides, or heparin oligosaccharides. Additional agents are also disclosed. The neuron can be a CNS neuron or peripheral neuron. Also disclosed herein are methods of treating neuronal injury in a subject comprising, administering to the subject an agent that binds RPTP?. Administration may be to a site of neuronal injury, to thereby induce neuronal outgrowth at the site of neuronal injury.

Abstract: A method of promoting neural cell regeneration is carried out by contacting a neural cell with a compound that inhibits the binding of a chondroitin sulfate proteoglycan (CSPG) to a cellular (e.g., trans-membrane) PTP? protein. The neural cell is associated with an injury or neurodegenerative condition.

Abstract: Transmembrane B ephrins and their Eph receptors signal hi-directionally. The presently claimed invention describes a cytoplasmic protein, designated PDZ-RGS3, which binds B ephrins through a PDZ domain, and has a regulator of heterotrimeric G protein signaling (RGS) domain. PDZ-RGS3 mediates signaling from the ephrin-B cytoplasmic tail. SDF-1, a chemokine with a G protein coupled receptor, or BDNF, act as chemoattractants for cerebellar granule cells, with SDF-1 action being selectively inhibited by soluble EphB receptor. The claimed invention reveals a pathway that links reverse signaling to cellular guidance, uncovers a novel mode of control for G proteins, and demonstrates a mechanism for selective regulation of responsiveness to neuronal guidance cues.

Abstract: The present invention relates to the discovery of a novel EPH receptor ligand, referred to hereinafter as “Elf-1”, which protein has apparently broad involvement in the formation and maintenance of ordered spatial arrangements of differentiated tissues in vertebrates, and can be used to generate and/or maintain an array of different vertebrate tissue both in vitro and in vivo.

Abstract: We describe here a new class of protein tyrosine phosphatases (PTP), called “PTP-NP” (for neural and pancreatic) receptors. The sequence of an exemplary PTP-NP gene (SEQ ID No. 1) indicates it encodes a receptor type PTP (SEQ ID No. 2) with a single tyrosine phosphatase domain. Comparison of PTP-NP with the other known PTPs reveals a cysteine-conserved motif in the extracellular domain and, together with their homology in the phosphatase domain, this defines a new subclass of receptor type PTPs.

Abstract: Disclosed is a method of isolating a ligand from a sample, the method including: providing a hybrid molecule including the receptor for the ligand covalently bonded to the first member of a specific binding pair; contacting sample with the hybrid molecule to form an affinity complex between the ligand and the hybrid molecule; and isolating the affinity complex using the second member of the specific binding pair. Also disclosed is a c-kit ligand, nucleic acid encoding such a ligand, and recombinant cells containing such nucleic acid. The c-kit ligand may be used to stimulate hematopoietic cell growth.
