Microorganisms comprising a maltose-inducible promoter and methods of use in producing biologics and introducing biologics to sites in a maltose-dependent manner. The microorganisms include a maltose-inducible promoter operably connected to a coding sequence of a biologic. The biologic may be a polypeptide or a nucleic acid. Polypeptide biologics may include lytic proteins and/or secreted proteins. Nucleic acid biologics may include antisense RNA, other types of RNA, or other types of nucleic acids. The microorganisms can be used to produce the biologics and/or introduce the biologics to in vitro or in vivo sites in a maltose-dependent manner. The microorganisms can also be used in maltose-dependent gene silencing.

Microorganisms and methods for producing biologics and introducing biologics to sites

Methods and microorganisms for systemically introducing a polypeptide in the bloodstream of a subject. The methods of the invention include administering into the gastrointestinal tract of a subject a bacterium configured to express and produce and release the polypeptide. The bacterium is administered in an amount effective to introduce the polypeptide in the bloodstream of the subject, preferably in a detectable amount. The microorganisms of the invention include lactic acid bacteria, such as, that comprise a recombinant gene configured to express a polypeptide to be systemically introduced.
