  • Publication number: 20200215110
    Abstract: This disclosure is directed to methods of preparing dendritic cells or other CD40 bearing antigen-presenting cells and methods of treating an infectious disease by using the dendritic cells or other antigen-presenting cells in combination with anti-chemorepellant agents. This disclosure is further directed to methods of preparing T cells and methods of treating an infectious disease by using activated T cells optionally in combination with anti-chemorepellant agents. The antigen presenting cells of the disclosure are activated by incubation with a pathogen or pathogen-infected cells and fusion proteins. The T cells of the disclosures are activated by incubation with activated antigen-presenting cells that were activated by incubation with a pathogen or pathogen-infected cells and a fusion protein. In particular, the fusion protein comprises an antigen-binding domain, e.g., an antibody or antibody fragment, and a stress protein domain.

  • Publication number: 20190269729
    Abstract: This invention is directed to the treatment of cancers, e.g., inflammatory breast cancer, with NK (natural killer) cells wherein the cells are modified ex vivo such that their ability to overcome the chemorepellant effect of a tumor is enhanced. The cells may be genetically modified ex vivo and/or modified by contacting the cells ex vivo with an anti-chemorepellant agent. This invention also provides ex vivo modified NK cells, which are modified such that they express no or substantially no CXCR4 on their cell surface, or express CXCR7, or express a chimeric antigen receptor, or combinations thereof. The invention also relates to methods for treating a patient having a tumor, e.g., inflammatory breast cancer, by administering the modified NK cells, with or without treatment with other conventional anticancer treatments, e.g. , chemotherapy, radiotherapy, viral therapies, hormonal therapies, as well as other immunotherapies and anti-chemorepellant therapies.
