Abstract: Polypeptides, nucleic acids, and compositions thereof are provided that include a targeting moiety. The polypeptides, nucleic acids, and compositions that comprise them, can be used in methods to treat subjects, to alter CAR-expressing cells in subjects who may suffer from a disease such as a cancer or a pathogen.

Abstract: The present disclosure relates to a method of modulating one or more genetically modified cells, e.g., chimeric antigen receptor (CAR)-expressing cells, ex vivo and/or in vivo.

Abstract: Compositions and methods to increase the in vivo capacity of CD8+ T cells to kill HIV-infected and reactivated latent HIV-infected T cells (LHITC) to functionally cure HIV infection or improve the clinical course. Compositions and methods to increase the in vivo capacity of CD8+ T cells to kill CMV or CMV-infected cells are also provided.

Abstract: This invention provides methods for treating subjects infected with human immunodeficiency virus (HIV) which comprise administering to the subjects a radiolabeled antibody or agent effective to kill HIV infected cells, where the antibody or agent is specific for a HIV envelope glycoprotein. The invention also provides compositions and methods for making compositions of radiolabeled antibodies or agents to HIV envelope glycoproteins for treatment of HIV infection.

Abstract: Transgenic non-human animals are described comprising a transgene for a species-specific pathogen and transgene(s) for at least one receptor restricting infection of the pathogen to the host species. Also described is a method for creating the transgenic non-human animal of this invention and a method for screening an agent for the ability to inhibit infection by a species-specific virus using said transgenic non-human animal. The transgenic animal of this invention has a sustained productive viral infection and does not develop a virus-specific immune response, thereby resulting in an extremely useful self-contained system to investigate the factors modulating in vivo replication of human pathogens, the pathophysiological effect of pathogen replication and production, and the effectiveness of novel therapies and vaccines modifying or inhibiting the course of pathogenesis.

Abstract: This invention is directed to a chimeric mouse capable of mounting murine cellular and humoral immune response, where the chimeric mouse is tolerant of human tissue implanted therein. The chimeric mouse of this invention is capable of developing murine T cells and producing murine IgG antibodies, which T cells and antibodies are tolerant of the human tissue implanted in the mouse. This allows for the challenge of the vaccinated mouse with human-specific pathogens and determining the capacity of the vaccine to protect the cells in the implanted tissue from infection. This invention is also directed to a method for the development of the chimeric mouse, as well as to the use of the chimeric mouse for the screening of vaccines for human-specific pathogens.
