  • Publication number: 20250025501
    Abstract: Provided herein are genetically modified ungulate cells expressing a chimeric antigen receptor. Also provided herein are transgenic ungulate cells that can be used as cell carriers for the delivery of oncolytic viruses in cancer therapy. Also provided are transgenic ungulates comprising these cells, methods of making these cells, and methods of treating cancer by administering these cells to a subject in need thereof. Also provided are transgenic ungulate cells that express a chimeric antigen receptor and uses thereof.

  • Publication number: 20220062393
    Abstract: This document provides methods and materials involved in reducing cardiac xenograft rejection. For example, methods and materials for preparing transgenic pigs expressing reduced or no endogenous Sda or SDa-like glycans derived from the porcine ?1,4 N-acetyl-galactosaminyl transferase 2 (B4GALNT2) glycosyltransferase and/or reduced or no endogenous ?-Gal antigens, methods and materials for modifying the xenograft recipient's immunological response to non-Gal antigens (e.g. CD46, CD59, CD9, PROCR, and ANXA2) to reduce cardiac xenograft rejection, and methods and materials for monitoring the progress of xenotransplant immunologic rejection are provided.

  • Publication number: 20020187132
    Abstract: Methods for the selective targeting of a transgene to the media of coronary arteries or the highly efficient transfer of a transgene to the myocardium, based on chemical modifications of a normothermic cardiac perfusion system, are described. The described methods can be used to introduce recombinant genes into donor hearts for the treatment of the complications of heart transplantation, including rejection, infection and cardiac allograft vasculopathy. Also described are perfusion solutions and kits and articles of manufacture.
