摘要:
The present disclosure provides recombinant bacterial cells that have been engineered with genetic circuitry which allow the recombinant bacterial cells to sense a patient's internal environment and respond by turning an engineered metabolic pathway on or off. When turned on, the recombinant bacterial cells complete all of the steps in a metabolic pathway to achieve a therapeutic effect in a host subject. These recombinant bacterial cells are designed to drive therapeutic effects throughout the body of a host from a point of origin of the microbiome. Specifically, the present disclosure provides recombinant bacterial cells that comprise an amino acid catabolism enzyme for the treatment of diseases and disorders associated with amino acid metabolism, including cancer, in a subject. The disclosure further provides pharmaceutical compositions and methods of treating disorders associated with amino acid metabolism, such as cancer.

摘要:
The present disclosure provides methods for treating a disease or disorder by administering a programmed recombinant bacterial cell to a subject, wherein the programmed recombinant bacterial cell expresses a heterologous gene in response to an exogenous environmental condition in the subject, and wherein the programmed recombinant bacterial cell is no longer viable after either sensing the presence or absence of the same or a different exogenous environmental signal, which ultimately leads to the expression of a toxin which kills the recombinant bacterial cell. The disclosure further comprises the programmed recombinant bacterial cells, and pharmaceutical compositions comprising the programmed recombinant bacterial cells.
