Membrane peptidases play important roles in cell activation, proliferation and communication. Human fibroblast-like synoviocytes express considerable amounts of aminopeptidase N/CD13, dipeptidyl peptidase IV/CD26, and neprilysin/CD10, transmembrane proteins previously proposed to be involved in the regulation of intra-articular levels of neuropeptides and chemotactic mediators as well as in adh...

A novel molecular scaffold has been synthesized, and its synthesis and incorporation into new analogues of biologically active molecules will be discussed. A comparison of the inhibitory activity of these compounds to the known type-2 diabetes compound (sitagliptin) against dipeptidyl peptidase-4 (DPP-4) will be shown.

Dipeptidyl peptidase-4 inhibitors (DPP-4Is) inhibit the inactivation of incretin hormones while also affecting the immune system, since CD26/DPP-4 is involved in immune regulation. The current study shows that the use of DPP-4Is as therapy for type 2 diabetes patients may induce joint symptoms with decrease in plasma SDF-1α level.

This article is a brief review of the current non-insulin agents for diabetes mellitus in the United States, namely, sulfonylureas, biguanides, thiazolidinediones, meglitinides, α-glucosidase inhibitors, glucacon-like peptide-1 receptor agonists, dipeptidyl-peptidase-4 inhibitors, amylin agonists, bromocriptine, and colesevelam.

Type 2 diabetes is a chronic metabolic derangement that results from defects in both insulin action and secretion. New thiazolidinedione insulin sensitizers have been recently launched. New approaches with mechanisms different from current therapies are being explored, including novel ligands of peroxisome proliferator-activated receptor, glucagon receptor antagonists, dipeptidyl peptidase IV i...

An association between remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome and insulin or dipeptidyl peptidase-4 (DPP4) inhibitor therapy were previously reported. We encountered four cases of RS3PE syndrome with type 2 diabetes mellitus or impaired glucose tolerance (IGT) without insulin or DPP4 inhibitor medication.

In a search for plant homologues of dipeptidyl peptidase III (DPP III) family, we found a predicted protein from the moss Physcomitrella patens (UniProt entry: A9TLP4), which shared 61% sequence identity with the Arabidopsis thaliana uncharacterized protein, designated Nudix hydrolase 3. Both proteins contained all conserved regions of the DPP III family, but instead of the characteristic hexap...
