Provided herein are compositions and methods for the treatment of type 1 diabetes (T1D) in mammalian subjects. The compositions include lactic acid fermenting bacteria (LAB) expressing an IL-2 gene and a T1D-specific self-antigen (e.g., proinsulin (PINS)) gene. Exemplary methods include: orally administering to a mammalian subject, a therapeutically effective amount of the composition. The composition can be administered to the subject mucosally, resulting in delivery of the LAB into the gastrointestinal tract, where the LAB is released. Bioactive polypeptides expressed by the LAB are thus administered via mucosal delivery. The LAB may be selected to deliver a low-dose of IL-2 to the subject. The methods may not require concomitant systemic anti-CD3 antibody treatment. The methods may be suited for subjects possessing residual beta-cell function, e.g., those with recent-onset T1D.
The current disclosure provides microorganisms, such as lactic acid bacteria (e.g., Lactococcus lactis) containing an exogenous nucleic acid encoding an IL-10 polypeptide and an exogenous nucleic acid encoding a T1D-specific antigen (e.g., a proinsulin) polypeptide, wherein both exogenous nucleic acids are integrated into the bacterial chromosome. Such microbial strains are suitable for human therapy. The disclosure further provides compositions (e.g., pharmaceutical compositions) methods of using the microorganisms and compositions, e.g., for the treatment of type 1 diabetes (T1D), including those with residual beta-cell function, e.g., recent-onset T1D. The microorganism may be administered orally, delivers the microorganism into the gastrointestinal tract, where it is released and expresses the bioactive polypeptides. The methods of the present disclosure are particularly well suited for subjects possessing residual beta-cell function, e.g., for subjects with recent-onset T1D.

The present invention comprises the discovery and development of an effective cryoprotectant composition, without containing skim milk or any other animal-derived compounds, to achieve long-term stability of freeze-dried lactic acid bacteria (LAB), at different temperatures, whereby the retention of viability of the freeze-dried LAB after 6 months of storage, preferably after 9 months of storage, more preferably after 12 months of storage is more than 50%. The invention is in the field of producing freeze dried bacteria, in particular Lactic acid bacteria. More in particular, the invention relates to the use of a novel combination of cryoprotectants for increasing the viability of bacteria after freeze drying, improving the texture of the lyofilized cake for easy grinding and improving the long term stability of the freeze dried bacteria at different temperature conditions. The invention further relates to such freeze dried bacteria for use in food industry or in human or animal health applications. More in particular, the invention relates to the increased viability and long-term storage of recombinant bacteria capable of expressing heterologous proteins or peptides and administered to humans or animals for therapeutic or vaccination purposes.

The invention is in the field of use of engineered microbes for the delivery and administration of therapeutic peptidesor proteins to humans or animals suffering from a disease, or the use of engineered microbes for the delivery of antigens such as for vaccination purposes. More in particular, the invention relates to a recombinant microbe that has reduced capacity of colonizing the mucosa in comparison to its wild type ancestor, in particular when residing in the alimentary tract as part of a treatment or vaccination of a human or animal. In particular, the recombinant microbe contains an inactive thymidylate synthase gene that causes the reduced capability for the microbe to colonize in the alimentary tract. The invention also covers the use of said recombinantmicrobes comprising nucleic acids or vectors for expressing heterologous or homologous proteins; and also for delivery, especially therapeutic delivery, of the said proteins to animals or humans.

Lactococcus and useful as promoters. The invention further relates to vectors comprising the nucleic acids and host cells transformed therewith. The invention also covers the use of host cells comprising the nucleic acids or vectors for expressing heterologous or homologous proteins; and also for delivery, especially therapeutic delivery, of the said proteins to subjects.
