The Broad Institute of MIT and Harvard has announced a new research alliance with Novo Nordisk A/S in diabetes and cardiometabolic diseases. The collaboration will focus on advancing three programs over the next 3 years.
Research led by Duke University and the German Center for Diabetes Research shows the glucose-dependent insulinotropic polypeptide (GIP) receptor plays an essential role in the action of the type 2 diabetes drug Mounjaro (tirzepatide; Eli Lilly and Co.) in human pancreatic islets.
Nearly everyone with diabetes for >20 years will develop diabetic retinopathy or uveitis, which are collectively among the most common causes of premature blindness. Melanocortin is a short peptide that not only controls pigmentation, but that is most importantly expressed constitutively in the intraocular space where it serves essential functions suppressing inflammation in the retina, ultimately preventing blindness.
Type 1 diabetes mellitus (T1DM) is an autoimmune disease in which the person’s immune system destroys its own pancreatic islet cells that leads to complete loss of insulin production. Allogeneic pancreatic islet cell transplantation has been shown to replenish the vanished β-cell population and provide glycemic control, restoration of hypoglycemia awareness, and protection from severe hypoglycemic events. However, with allogeneic transplantation, there is a need for life-long immunosuppression to protect the islet grafts from allo- and autoimmunity.
Researchers at Indiana University School of Medicine are exploring avenues to heal wounds by identifying proteins that are active in fetuses, but largely inactive in adults and absent in diabetic adults. They have identified a protein called nonselenocysteine-containing phospholipid hydroperoxide glutathione peroxidase, or NPGPx, that fits the bill and could be the basis for therapies aimed at diabetic wound healing. NPGPx is a direct transcriptional target of miR-29. miR-29 is downregulated in fetal tissue, thus NPGPx is active in fetal tissue but becomes mostly inactive in the skin after birth.
Metabolic health is at an odd juncture. With the advent of glucagon-like peptide (GLP-1) agonists, pharmacologically induced weight loss has matured into a viable therapeutic option at long last. And research into the drug class is continuing apace.
Genprex Inc. has entered into a license agreement with the University of Pittsburgh designed to strengthen its diabetes program. The agreement grants Genprex a worldwide, exclusive license to certain patent applications and related technology and a worldwide, nonexclusive license to use certain related know-how, all related to modulating autoimmunity in type 1 diabetes by using gene therapy.
Scientists from Orsobio Inc. and affiliated organizations have described preclinical data for the novel liver-targeted mitochondrial protonophore TLC-6740, being developed for the treatment of metabolic disease. In vitro, mild mitochondrial uncoupling caused by TLC-6740 had pleotropic metabolic benefits in multiple cell lines. TLC-6740 increased mitochondrial potential, oxygen consumption rate and tricarboxylic acid (TCA) cycle flux, and it also inhibited de novo lipogenesis with EC50 values of 6.9 µM.
It is largely known that oral drug delivery for macromolecules is often limited by the degradative environment of the gastrointestinal tract. Researchers from the Massachusetts Institute of Technology and their collaborators have presented Robocap, an oral mucus-clearing drug-delivery capsule that enhances the gastrointestinal absorption of drugs.
