  • Publication number: 20250059507
    Abstract: Compositions of matter and methods of treatment based on generation of T cells capable of ameliorating or treating pathologies associated with improper immune activation. Chimeric antigen receptor (CAR) T cells are generated which possess tolerogenic properties based on enhanced expression of NR2F6. NR2F6 is enhanced through transfection of cells with a modified siRNA sequence. NR2F6 expression is upregulated through tissue culture modification, and NR2F6 expression vectors are introduced to the cell of interest.

  • Patent number: 11712474
    Abstract: Disclosed are means of stimulating systemic immunity and reduction of post-surgery tumor metastasis through the concurrent intralymphatic inhibition of NR2F6 and treatment with cannabidiol. In some embodiments NR2F6 is inhibited by high pressure transient delivery of short interfering RNA into tumor draining lymph nodes concurrent with systemic administration of cannabidiol. This combination may be performed together with means that induce immunogenic tumor cell death. Through the combination of immunogenic cell death and immune stimulation, the invention provides a means of enhancing the abscopal effect and in some embodiments to cause immunological mediated destruction primary and secondary neoplasia.

  • Patent number: 11241427
    Abstract: Disclosed are compounds useful for alteration of NR2F6 activity. In some embodiments of the invention compounds disclosed are utilized for stimulation of NR2F6 activity, alone, or in combination with PKC activation. In other embodiments, the invention teaches use of compounds for inhibition of NR2F6 activation. Stimulation of NR2F6 within the context of the invention is useful, intra alia, for induction of immune inhibition, or stimulation of cellular proliferation without significant induction of differentiation. Inhibition of NR2F6 is desired in situations where the practitioner of the invention seeks to augment immune response, or induce cellular differentiation. In another embodiment, inhibition of NR2F6 expression is desired in situations where inhibition of cancer or cancer stem cells is needed.

  • Publication number: 20210403866
    Abstract: Cancer associated inflammation has been reported to act as an immune suppressive mechanism through augmentation of myeloid suppressor cells, as well as downregulation of T cell receptor (TCR) signaling through the cleavage of the CD3 zeta chain. The teachings herein show the effects of concurrent anti-inflammatory treatment of dendritic cells (DC) using cannabidiol (CBD) together with inhibition of an immunological checkpoint, that is, silencing of NR2F6. Mixed lymphocyte cultures are used to increased potency of dendritic cells to stimulate allogeneic T cell proliferative and cytokine responses by the combination of NR2F6 gene silencing together with CBD. CBD alone appeared to inhibit DC maturation and allogestimulatory activity. These data support the utilization of small molecule inhibitors of NR2F6 together with CBD as combination therapies for immune modulation.

  • Publication number: 20210317180
    Abstract: Disclosed are compositions of matter, cells, and methodologies for generation of chimeric antigen receptor (CAR) cells with inhibited or absent NR2F6 activity. In one embodiment, a CAR possessing affinity to a tumor antigen is transfected onto T cells that possess reduced or absent NR2F6 activity, said reduction or absence of NR2F6 activity leading to increased production of cytokines associated with inhibition of tumor growth, metastasis or angiogenesis, and/or augmentation of tumor cytotoxicity. Inhibition of NR2F6 activity may be performed ex vivo on said T cells or in vivo by administration of small molecule inhibitors, siRNA, shRNA or gene editing. In some embodiments other immune cells are substituted for CAR-T cells.

  • Patent number: 11090332
    Abstract: Disclosed are antigen specific cancer vaccines in which immunogenic epitopes are produced intracellularly by administration of modified mRNA encoding said immunogenic epitopes. In one embodiment of the invention, said modified mRNA encodes peptides derived from the protein survivin. By directly inducing gene expression of the antigens to which an immune response is desired, immunogenic peptides are generated intracellularly, thus allowing for a wider repertoire of epitopes to be presented to the adaptive immune system, which augments likelihood of successful induction of immunity.

  • Publication number: 20210059962
    Abstract: Disclosed are means, methods, and compositions of matter for stimulation of T regulatory (Treg) cells by cannabidiol. In one embodiment, administration of cannabidiol is performed in an animal suffering from autoimmunity.
