Reconstructing the free-energy landscape of Met-enkephalin using dihedral Principal Component Analysis and Well-tempered Metadynamics [PDF]
, 2012 Well-Tempered Metadynamics (WTmetaD) is an efficient method to enhance the reconstruction of the free-energy surface of proteins. WTmetaD guarantees a faster convergence in the long time limit in comparison with the standard metadynamics. It still suffers however from the same limitation, i.e.

Proenkephalin, neutrophil gelatinase-associated lipocalin, and estimated glomerular filtration rates in patients with sepsis [PDF]
, 2017 Background: Proenkephalin (PENK) has been suggested as a novel biomarker for kidney function. We investigated the diagnostic and prognostic utility of plasma PENK in comparison with neutrophil gelatinase-associated lipocalin (NGAL) and estimated ...

Proceedings of the National Academy of Sciences of the United States of America, 1977 The brain peptides alpha- and beta-endorphin, leucine- and methionine-enkephalin, as well as the opiate normorphine, have been evaluated by microiontophoresis for their effects on neuronal activity in several regions of the rat brain. In cerebral cortex,

The Opioid System in Temporal Lobe Epilepsy: Functional Role and Therapeutic Potential
Frontiers in Molecular Neuroscience, 2017 Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease.

Influence of Mutations of Conserved Arginines on Neuropeptide Binding in the DPP III Active Site
Molecules, 2023 Dipeptidyl peptidase III (DPP III), a zinc exopeptidase, is involved in the final steps of intercellular protein degradation and has a marked affinity for opioid peptides such as enkephalins and endomorphins.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis
BMEMat, EarlyView.This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

A drug delivery strategy: binding enkephalin to asialoglycoprotein receptor by enzymatic galactosylation. [PDF]
PLoS ONE, 2014 Glycosylation of biopharmaceuticals can mediate cell specific delivery by targeting carbohydrate receptors. Additionally, glycosylation can improve the physico-chemical (drug-like) properties of peptide based drug candidates.

Biased Metropolis Sampling for Rugged Free Energy Landscapes [PDF]
AIP Conference Proceedings Vol.690, 63-73 (2003), 2003 Metropolis simulations of all-atom models of peptides (i.e. small proteins) are considered. Inspired by the funnel picture of Bryngelson and Wolyness, a transformation of the updating probabilities of the dihedral angles is defined, which uses probability densities from a higher temperature to improve the algorithmic performance at a lower temperature.
