Tissue targeted antigenic activation of the immune response to cancers

The invention provides in part methods of treating cancers of a specific organ or tissue by administering a composition that is antigenically specific for one or more microbes that are pathogenic in the specific organ or tissue in which the cancer is situated. The formulations of the invention thereby facilitate activation of a treatment response to a cancer in a particular tissue or organ. The compositions may for example include killed or attenuated microbial pathogens, and may be administered at sites distant from the cancer, for example the skin. In some embodiments, microbial species of endogenous flora that are known to cause infection in the relevant organ or tissue may be used in the formulation of the antigenic compositions. In alternative embodiments, exogenous microbial pathogens that are known to cause infection in the relevant organ or tissue may be used in the formulation of the antigenic compositions. The administration of the immunogenic compositions may be repeated relatively frequently over a relatively long period of time. In embodiments for intradermal or subcutaneous injection, dosages may be adjusted so that injections reproduce a consistent visible delayed inflammatory immune reaction at the successive site or sites of administration.

Tissue targeted complement modulators

Systemic suppression of the complement system has been shown to be effective to treat inflammatory disease, yet at the potential cost of compromising host defense and immune homeostasis. Herein disclosed are methods for antigen-specific targeting of complement inhibitors that show that complement inhibitors targeted to the proximal tubular epithelium protect against tubulointerstitial injury and renal dysfunction in a rat model of nephrosis. It is shown that appropriate targeting of a systemically administered complement inhibitor to a site of disease markedy enhances efficacy and obviates the need to systemically inhibit complement. Additionally, it is shown by specifically inhibiting the terminal pathway of complement, that the membrane attack complex (MAC) plays a key role in proteinuria-induced tubulointerstitial injury, thus establishing the MAC as a valid target for pharmacological intervention in proteinuric disorders. The disclosed are compositions can be used in methods of treating pathogenic diseases and inflammatory conditions by modulating the complement system.
