Recent Advancements in the Characterization of D‐Amino Acid and Isoaspartate Post‐Translational Modifications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT One of the great triumphs of mass spectrometry‐based peptide and protein characterization is the characterization of their modifications as most modifications have a characteristic mass shift. What happens when the modification does not change the mass of the peptide?

Thermometer Ions, Internal Energies, and In‐Source Fragmentation in Ambient Ionization

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Ionization and fragmentation are at the core of mass spectrometry. But they are not necessarily separated in space, as in‐source fragmentation can also occur. Here, we survey the literature published since our 2005 review on the internal energy and fragmentation in electrospray ionization sources.

Episodic Ethanol Exposure in Adolescent Rats Causes Residual Alterations in Endogenous Opioid Peptides

Frontiers in Psychiatry, 2018
Adolescent binge drinking is associated with an increased risk of substance use disorder, but how ethanol affects the central levels of endogenous opioid peptides is still not thoroughly investigated.

Cerebrospinal Fluid Proenkephalin Predicts Striatal Atrophy Decades before Clinical Motor Diagnosis in Huntington's Disease

Movement Disorders, EarlyView.
Abstract Background Huntington's disease (HD) is characterized by early, selective, progressive vulnerability of striatal medium spiny neurons (MSNs). Proenkephalin (PENK), a precursor of opioid peptides abundantly expressed in MSNs, is a promising biomarker of striatal integrity, but region‐specific associations and its potential for early‐stage ...

Design of Experiments (DoE)‐Optimized Polymeric Oxytocin Nanoparticles for Enhanced Nose‐to‐Brain Delivery

Small, EarlyView.
Intranasal (IN) delivery of PEGylated PLGA nanoparticles (NPs) loaded with oxytocin (OT) (OT‐NP‐PEG) is investigated as a strategy to enhance OT transport to the brain for treating autism and other neuropsychiatric disorders. The optimized NP formulation demonstrates appropriate physicochemical characteristics, improved stability, and enhanced mucosal ...

The dopamine D1-D2 receptor heteromer in striatal medium spiny neurons: evidence for a third distinct neuronal pathway in basal ganglia

Frontiers in Neuroanatomy, 2011
Dopaminergic signaling within the basal ganglia has classically been thought to occur within two distinct neuronal pathways; the direct striatonigral pathway which contains the dopamine D1 receptor and the neuropeptides dynorphin and substance P, and the
