Abstract:
NK cell based cancer immunotherapy, and particularly genetically modified NK92 cell-based immunotherapy is enhanced by expression CXCL12 and/or by suppression or deletion of CXCR4 in the natural killer cells to so reduce aggregation, rejection, and/or fratricide of the natural killer cells.
Abstract:
The invention relates to plasmids capable of expressing a protein targeting immune cells when transformed into a lactic acid bacterial cell, wherein the protein is chosen from the group consisting of murine and human CXCL12 1α; CXCL17 and Ym1. The invention further relates to lactic acid bacteria transformed with a said plasmid, as well as the use of said lactic acid bacteria for wound healing in humans and animals.
Abstract:
Tetrapeptides consisting of (I or V)-X1-K-X2, where X1 can be selected from E, Q or K, and X2 can be selected from M, F, I, W, or V, exhibit diverse bioactivities. They are multi-functional effector molecules to stimulate keratinocytes migration; neutralize the proinflammatory effect of bacterial cell wall components such as lipoteichoic acids of the Gram-positive S. aureus; and induce angiogenesis in cultured human umbilical vein endothelial cells. The downregulation of pro-inflammatory condition was also demonstrated using SOR-300-FT psoriasis skin model for representative peptide. The bioactivity was also supported by gene profiling study upon treatment of normal skin tissues using EPIDERM TM skin substitutes. The inventive peptides with diverse bioactivities are useful for treating various skin conditions including, but not limited to, acute or chronic wounds, striae distensae, aging skin, hair control, inflammatory skins such as psoriasis, atopic dermatitis and rosacea and for unwanted hair removal or for conditions such as removal of skin tags.
Abstract:
The present invention provides a non-viral vector which comprises a sequence encoding an RNA replicase and a nuclear localisation sequence. The vector may also comprise a nucleotide sequence of interest (NOI). The vector may be used to deliver an NOI to a target cell.
Abstract:
Methods are described pertaining to the use of fractalkine (FKN, CX3CL1 ) and its receptor CX3CRI for treatment of neuroinflammation and/or neurodegeneration. Also included are methods for treatment of neuroinflammation and/or neurodegenerative diseases, comprising: administering to cells of a subject in need of such treatment, an adeno-associated virus that comprises a functional fractalkine gene operably linked to transcriptional control elements. The methods are used to treat or ameliorate Parkinson's disease, neuroinflammatory and/or neurodegenerative diseases including, but not limited to, Alzheimer's disease, epilepsy, aging, and traumatic brain injury.
Abstract:
This application is directed to chemokine-immunoglobulin fusion polypeptides and chemokine-polymer conjugates. The fusion polypeptides and conjugates can be used for treating chemokine receptor-mediated disorders and modulating inflammation, inflammatory cell motility, cancer cell motility, or cancer cell survival.
Abstract:
Provided are compositions and methods for inhibiting cell growth. The cells that are targeted by the compositions and methods of the invention express an antigen, a mimotope of the antigen, or a CXCR4 chemokine receptor. The method entails administering to an individual a polynucleotide encoding an immunoglobulin Fc and an antigen expressed by the cells or a mimotope of the antigen. The method also involves administering to the individual a composition which contains a polynucleotide encoding an immunoglobulin Fc and an antagonist peptide of a CXCR4 chemokine receptor expressed by the cells. Also provided are proteins encoded by the polynucleotides.
Abstract:
The invention provides compositions and methods of treating various conditions, including tumors, with compositions comprising dendritic cells expressing exogenous chemokines.
Abstract:
A method of treating a cardiomyopathy in a subject includes administering directly to or expressing locally in a weakened, ischemic, and/or peri-infarct region of myocardial tissue of the subject an amount of SDF-1 effective to cause functional improvement in at least one of the following parameters: left ventricular volume, left ventricular area, left ventricular dimension, cardiac function, 6-minute walk test, or New York Heart Association (NYHA) functional classification.
