Previous work has shown that certain β(3)-peptides can effectively mimic the side chain display of an α-helix and inhibit interactions between proteins, both in vitro and in cultured cells. Here we describe a β(3)-peptide analog of GLP-1, CC-3(Act), that interacts with the GLP-1R extracellular domain (nGLP-1R) in vitro in a manner that competes with exendin-4 and induces GLP-1R-dependent cAMP signaling in cultured CHO-K1 cells expressing GLP-1R.

Mast cells, immune sentinels that respond to various stimuli in barrier organs, provide defense by expressing pattern recognition receptors, such as Toll-like receptors (TLRs). They may affect inflammatory responses and wound healing. Here, we investigated the effect of TLR2/6-stimulated mast cells on wound healing in keratinocytes.

P2X receptors (P2XRs) are adenosine 5'-triphosphate (ATP)-gated ion channels comprising homomeric and heteromeric trimers of seven subtypes (P2X1-P2X7) that confer different rates of desensitization. The helical recoil model of P2XR desensitization proposes stability of the cytoplasmic cap sets the rate of desensitization, but timing of its formation is unclear for slow-desensitizing P2XRs. We report cryo-electron microscopy structures of full-length wild-type human P2X4 receptor in apo closed, antagonist-bound inhibited, and ATP-bound desensitized states.

Background: Type 2 diabetes (T2D) causes increased health care resource utilization (HCRU) and costs in the United States. People with T2D are more likely to have atherosclerotic cardiovascular disease (ASCVD), which is associated with significant morbidity and mortality. Medical associations recommend cardioprotective antidiabetic medications, including sodium-glucose cotransporter-2 inhibitors (SGLT2is) and glucagon-like peptide 1 receptor agonists (GLP-1 RAs), to reduce the risk of cardiovascular events in patients with T2D with established, or a high risk of, ASCVD, but not all eligible patients receive these medications.

Background: Both glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and continuous glucose monitoring (CGM) have been shown to improve glycated hemoglobin A1c (A1c) levels among patients with type 2 diabetes mellitus (T2DM). Recently, a US real-world study found statistically significant improvements in A1c levels among patients using GLP-1 RA and a CGM device, compared with a matched cohort receiving only GLP-1 RA.

Objectives: To assess the cost-effectiveness from a US payer perspective of initiating CGM (FreeStyle Libre Systems) in people living with T2DM using a GLP-1 RA therapy, compared with GLP-1 RA alone.
