  • Publication number: 20230183297
    Abstract: The present invention relates to methods of treating a disease characterised by aberrant cell proliferation (e.g., a cancer) in a human subject in need thereof. In particular, the present invention relates to treating the above conditions by administering a therapeutically effective amount of at least one agent that increases activation of a receptor of at least one type II interferon and/or type I interferon, and administering to the subject at least one agent that inhibits the Hedgehog (Hh) signalling pathway (e.g., Vismodegib). Also provided are pharmaceutical compositions, including controlled release pharmaceutical compositions, containing at least one agent that increases activation of a receptor of at least one type II interferon and/or type I interferon (e.g., a checkpoint inhibitor), an inhibitor of Hh signalling pathway, and a controlled release matrix such as a SiO2 matrix gel.

  • Patent number: 11273170
    Abstract: The present invention relates to methods of treating cancer in a human subject in need thereof. In particular, the present invention relates to treating a cancer by administering a recombinant virus which expresses one or more biotherapeutic agents in a subject, and administering to the subject a nucleotide analogue or nucleotide precursor analogue chemotherapeutic agent. The invention further relates to method for treating cancer by administering a nucleotide analogue or nucleotide precursor analogue chemotherapeutic agent and a caspase inhibitor, and, optionally, also administering a recombinant virus expressing one or more biotherapeutic agents in the subject. The invention also relates to a method for treating cancer by administering purified interferon gamma to a subject and administering to the subject a nucleotide analogue or nucleotide precursor analogue chemotherapeutic agent.

  • Publication number: 20080201122
    Abstract: The present invention relates generally to a computer model of an adaptive immune response. One embodiment of the invention relates to a computer model of an adaptive immune response within the framework of signals conveyed at the site of antigen exposure. Another embodiment of the model includes a representation of complex physiological regulatory mechanisms related to, for example, cellular dynamics, mediator production, antigen-presenting cell (APC) recruitment, APC maturation, lymphocyte activation, lymphocyte trafficking, and/or lymphocyte effector function. In another embodiment, the model can account for mediator production in response to antigen within a chronically inflamed peripheral tissue, as well as the regulatory effects of mediators on APC and lymphocyte population dynamics, including maturation, activation, and apoptosis, and the regulatory effects of mediators produced by APCs and lymphocytes on a chronically inflamed peripheral tissue.
