Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

open access: yesPhytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Altered hippocampal gene expression, glial cell population, and neuronal excitability in aminopeptidase P1 deficiency

open access: yesScientific Reports, 2021
Inborn errors of metabolism are often associated with neurodevelopmental disorders and brain injury. A deficiency of aminopeptidase P1, a proline-specific endopeptidase encoded by the Xpnpep1 gene, causes neurological complications in both humans and ...

Activatable smart contrast agents for photoacoustic imaging

open access: yesSmart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Analyzing the Binding of Co(II)-specific Inhibitors to the Methionyl Aminopeptidases from \u3cem\u3eEscherichia coli\u3c/em\u3e and \u3cem\u3ePyrococcus furiosus\u3c/em\u3e [PDF]

open access: yes, 2009
Methionine aminopeptidases (MetAPs) represent a unique class of protease that is capable of the hydrolytic removal of an N-terminal methionine residue from nascent polypeptide chains.

Depth‐dependent mechanisms regulate accumulation of plant‐ and microbial‐derived residues under long‐term nitrogen addition in a semiarid grassland

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐ and microbial‐derived residues constitute the primary sources of soil organic carbon (SOC) in grassland ecosystems. However, their differential responses to chronic nitrogen (N) enrichment and the depth‐dependent mechanisms governing their accumulation remain ...

A Molecular Analysis of the Aminopeptidase P-Related Domain of PID-5 from Caenorhabditis elegans

open access: yesBiomolecules, 2023
A novel protein, PID-5, has been shown to be a requirement for germline immortality and has recently been implicated in RNA-induced epigenetic silencing in the Caenorhabditis elegans embryo.

Proteolysis at the extracellular matrix interface: Molecular architects and regulators in health and disease

open access: yesThe FEBS Journal, EarlyView.
The extracellular matrix (ECM) is a dynamic scaffold that orchestrates tissue architecture and cellular communication. A critical but underexplored interplay between proteases and cluster of differentiation molecules (CD) governs ECM turnover and directs cell fate.

Potential Activities of Freshwater Exo- and Endo-Acting Extracellular Peptidases in East Tennessee and the Pocono Mountains

open access: yesFrontiers in Microbiology, 2018
Proteins constitute a particularly bioavailable subset of organic carbon and nitrogen in aquatic environments but must be hydrolyzed by extracellular enzymes prior to being metabolized by microorganisms.
