Abstract:

Bifidobacterium has been developed for the oral delivery of peptides and has the added beneficial effect on our bodies through its probiotic properties. Here, we utilize Bifidobacterium as a delivery system to orally deliver Glucagon like peptide-2 (GLP-2). We constructed vector derived from pET-31b(+) to construct a Bifidobacterium longum expressing GLP-2. We then determined the bioactivity of recombinant Bifidobacterium in Caco-2 cells. Finally, we quantified newly synthesized ApoB48 and chylomicron production in mice infused with exogenous GLP-2 or Bifidobacterium expressing GLP-2. Results based on secretion of the triglyceride (TG)-rich lipoprotein (TRL)-ApoB48 and secretion of chylomicron revealed that recombinant Bifidobacterium was efficient in treating intestinal dysfunction,suggesting an alternative way to use Bifidobacterium as a delivery system to deliver GLP-2 for gastrointestinal nutrition coordination.
