The chromogranins (chromogranin A and chromogranin B), secretogranins (secretogranin II
and secretogranin III), and additional related proteins (7B2, NESP55, proSAAS, and VGF) …

The field of proteomics is undergoing rapid development in a number of different areas
including improvements in mass spectrometric platforms, peptide identification algorithms …

Background Probiotic bacteria are known to modulate host immune responses against
various pathogens. Recently, extracellular vesicles (EVs) have emerged as potentially …

The GalNAc O-glycosylation on Ser/Thr residues of extracellular proteins has not been well
characterized from a proteomics perspective. We previously reported a sialic acid capture …

The adrenal medulla is composed predominantly of chromaffin cells producing and
secreting the catecholamines dopamine, norepinephrine, and epinephrine. Catecholamine …

Neuropeptides are essential for cell–cell communication in neurological and endocrine
physiological processes in health and disease. While many neuropeptides have been …

Neuropeptides mediate cell–cell signaling in the nervous and endocrine systems. The
neuropeptidome is the spectrum of peptides generated from precursors by proteolysis within …

Low-molecular weight proteins and peptides (LMWPs,< 30 kDa) in human plasma serve as
potential biomarkers or drug targets and are endowed with desirable traits for biological and …

Neuropeptides are short peptides in the range of 3–40 residues that are secreted for cell-cell
communication in neuroendocrine systems. In the nervous system, neuropeptides comprise …

Peptide hormones and neuropeptides are signaling molecules that control diverse aspects
of mammalian homeostasis and physiology. Here we provide evidence for the endogenous …
