  • Patent number: 10596201
    Abstract: An acellular soft tissue-derived matrix includes a collagenous tissue that has been delipidated and decellularized. Adipose tissue is among the soft tissues suitable for manufacturing an acellular soft tissue-derived matrix. Exogenous tissuegenic cells and other biologically-active factors may be added to the acellular matrix. The acellular matrix may be provided as particles, a slurry, a paste, a gel, or in some other form. The acellular matrix may be provided as a three-dimensional scaffold that has been reconstituted from particles of the three-dimensional tissue. The three-dimensional scaffold may have the shape of an anatomical feature and serve as a template for tissue repair or replacement. A method of making an acellular soft tissue-derived matrix includes steps of removing lipid from the soft tissue by solvent extraction and chemical decellularization of the soft tissue.

  • Publication number: 20190328787
    Abstract: Described herein are methods for producing and utilizing T cells comprising chimeric antigen receptors (CAR) comprising a portion of the extracellular domain of a Tumor Necrosis Factor (TNF) superfamily receptor ligand, e.g., A PRoliferation-In-Ligand (APRIL). The CAR T cells of this present invention overcome resistance to anti-BCMA targeted therapies and utilize dimerizing and trimerizing transmembrane domains for optimal function. Further, this invention is related to methods of treating cancer, plasma cell diseases or disorders, or autoimmune diseases or disorders.

  • Publication number: 20190142572
    Abstract: Allografts for soft tissue repair, including breast reconstruction and other plastic surgery procedures, are disclosed. One allograft is made from decellularized dermal tissue and constitutes a collagen matrix having substantially uniform density and porosity. Another allograft is a hybrid bilayer tissue form that is made from decellularized dermal and adipose tissues. Methods for making both allografts are also disclosed.

  • Patent number: 9676858
    Abstract: We have constructed bispecific antibody engaging molecules which have one arm that specifically engages a tumor cell which expresses the human EGFRvIII mutant protein on its surface, and a second arm that specifically engages T cell activation ligand CD3. The engaging molecules are highly cytotoxic and antigen-specific. These may be used as therapeutic agents.

  • Publication number: 20110177612
    Abstract: The present invention relates to methods of identifying whether a candidate compound is a modulator of a G protein-coupled receptor (GPCR). In preferred embodiments, the GPCR is human. In other preferred embodiments, the GPCR is coupled to Gi and lowers the level of intracellular cAMP. In other preferred embodiments, the GPCR is expressed endogenously by adipocytes. In further preferred embodiments, the GPCR inhibits intracellular lipolysis. In other further preferred embodiments, the GPCR is a nicotinic acid receptor. The present invention also relates to methods of using a modulator of said GPCR. Preferred modulator is agonist. Agonists of the invention are useful as therapeutic agents for the prevention or treatment of metabolic-related disorders, including dyslipidemia, atherosclerosis, coronary heart disease, stroke, insulin resistance, and type 2 diabetes.
