Most crude venom from Polybiapaulista is composed of short, linear peptides; however, only five of these peptides are structurally and functionally characterized. Therefore, the peptides in this venom were profiled using ...

Peptides represent a large class of cell signaling molecules, and they are mainly produced by the classical secretory pathway or during protein degradation. The peptide profile of Danio rerio (zebrafish) shows a lack of ...

Parkinson's disease (PD) is a chronic neurodegenerative disorder mainly attributed to the progressive loss of dopaminergic neurons in the substantia nigra, which leads to uncontrolled voluntary movements causing tremors, ...

Increasing resistance in antibiotic and chemotherapeutic treatments has been pushing studies of design and evaluation of bioactive peptides. Designing relies on different approaches from minimalist sequences and endogenous ...

Previous studies have shown that cowpea protein positively interferes with cholesterol metabolism. In this study, we evaluated the ability of the fraction containing peptides of <3 kDa, as well as that of the Gln-Asp-Phe ...

Cells produce and use peptides in distinctive ways. In the present report, using isotope labeling plus semi-quantitative mass spectrometry, we evaluated the intracellular peptide profile of TAP1/beta 2m(-/-) (transporter ...

We have covalently conjugated an N-terminus Plasmodium vivax apical membrane antigen-1 (AMA-1) peptide to functionalized carbon nanotubes (f-CNT). Immunological characterization of this molecular conjugate revealed that ...

Many scorpion accidents occur in the Brazilian Amazonian region and are frequently caused by Tityus obscurus. Approximately 5% of the crude venom of this species is composed of short linear, non-disulfide-bridged peptides, ...
