Exploring the insulin secretory properties of the PGD2-GPR44/DP2 axis in vitro and in a randomized phase-1 trial of type 2 diabetes patients.

AIMS/HYPOTHESIS:GPR44 (DP2, PTGDR2, CRTh2) is the receptor for the pro-inflammatory mediator prostaglandin D2 (PGD2) and it is enriched in human islets.In rodent islets, PGD2 is produced in response to glucose, suggesting that the PGD2-GPR44/DP2 axis may play a role in human islet function during hyperglycemia.Consequently, the aim of this work was

Purification of reversibly oxidized proteins (PROP) reveals a redox switch controlling p38 MAP kinase activity.

Oxidation of cysteine residues of proteins is emerging as an important means of regulation of signal transduction, particularly of protein kinase function.Tools to detect and quantify cysteine oxidation of proteins have been a limiting factor in understanding the role of cysteine oxidation in signal transduction.As an example, the p38 MAP kinase is

Paraphrenia: a lost concept

Introduction Paraphrenia consists on a syndrome of insidious development with a chronic delirium of great phenomenological richness, predominating productive or delusional-hallucinatory forms and with time it evolves to pure fabulation.Delusions appear in 100% of cases predominating persecution, reference and false identifications.It is a classic t
