摘要:
Provided herein, inter alia, are compositions and kits comprising a bacterial cell and a tumor penetrating agent. Also provided are methods of treating cancer in a subject including the step of administering to the subject an effective amount of a bacterial cell and a tumor penetrating agent. Provided are methods of stimulating an immune system in a subject. The methods include administering to the subject an effective amount of a bacterial cell and a tumor penetrating agent. Also provided are methods of enhancing delivery of an anti-cancer agent to a tumor cell including the step of contacting the tumor cell with a bacterial cell, a tumor penetrating agent and an anti-cancer agent.
摘要:
In one embodiment, a single modality cancer immunotherapy regimen that includes a therapeutic composition is provided. Such a therapeutic composition may include a Salmonella strain comprising a plasmid that expresses an shRNA molecule that suppresses the expression of an immunosuppressive target and suppresses tumor growth. In some aspects, the Salmonella strain is an attenuated Salmonella typhimurium strain. In other aspects, the immunosuppressive target is STAT3, IDO1, IDO2, Arginase 1, iNOS, CTLA-4, TGF-β, IL-10, pGE2 or VEGF. In one embodiment, the immunosuppressive target is IDO1 or Arg1 and the shRNA molecule is any one of SEQ ID NO:5-14.
