Under Inflammatory bowel disease (IBD), impaired intestinal barrier from lumen is highly associated with ongoing IBD symptoms and it also contributes as a precursor for IBD. Current IBD therapeutics lack on mucosal regeneration, which the unmet needs could be the next first in class therapeutics for IBD. Here, we propose NIPEP-IBD, a synthetically modified peptide that promotes adhesion, migration, and differentiation of intestinal epithelial cells via interaction of integrin beta 1. From NIBEC’s specialized peptide discovery platform screening, specifically sequenced peptide has been selected for regenerative functional peptide, termed NIPEP-IBD.
