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

The 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.

HISTOCHEMICAL DEMONSTRATION OF AMINOPEPTIDASE [PDF]

Journal of Histochemistry & Cytochemistry, 1956
A histochemical method for demonstration of aminopeptidase in tissue sections using the substrates l-leucyl β-naphthylamide and dl-alanyl β-naphthylamide is presented. The method may also be quantitated on tissue sections. The successful histochemical demonstration of the enzyme with both substrates is dependent upon the use of frozen-

Mechanisms of HIV Protein Degradation into Epitopes: Implications for Vaccine Design

Viruses, 2014
The degradation of HIV-derived proteins into epitopes displayed by MHC-I or MHC-II are the first events leading to the priming of HIV-specific immune responses and to the recognition of infected cells.

Proteolytic remodelling of the extracellular matrix by pericytes

The FEBS Journal, EarlyView.
Pericytes are specialised perivascular cells intimately connected with endothelial cells and essential for the maintenance of vascular beds. They contribute to the formation and remodelling of the extracellular matrix by actively secreting proteases and protease inhibitors.

Type II Secretion-Dependent Aminopeptidase LapA and Acyltransferase PlaC Are Redundant for Nutrient Acquisition during Legionella pneumophila Intracellular Infection of Amoebas

mBio, 2018
Legionella pneumophila genes encoding LapA, LapB, and PlaC were identified as the most highly upregulated type II secretion (T2S) genes during infection of Acanthamoeba castellanii, although these genes had been considered dispensable on the basis of the

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Land use overrides climatic controls on soil organic nitrogen transformations: Contrasting responsiveness between forest and cropland ecosystems

Functional Ecology, Volume 40, Issue 7, Page 2128-2142, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil organic nitrogen (SON) transformation is critical for global nutrient cycling and ecosystem productivity, yet how its responsiveness to climate change differs across diverse land use types remains poorly resolved.

Biochar and Sediment Amendments Alter Soil Nitrogen Mineralization: Microbial Biomass and Extracellular Enzyme Activity

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Co‐application of Mn‐modified biochar and fishpond sediment markedly improves soil pH, organic carbon, microbial biomass, and nitrogen mineralization, demonstrating a synergistic effect that enhances soil fertility, microbial activity, and nutrient cycling for sustainable agricultural management.

Aminopeptidases do not directly degrade tau protein

Molecular Neurodegeneration, 2010
Background Tau hyperphosphorylation and aggregation to form intracellular neurofibrillar tangles is prevalent in a number of tauopathies. Thus there is current interest in the mechanisms involved in Tau clearance. It was recently reported that Tau can be

Tolerance to Phosphorus Deficiency Improves Seed Phytic Acid‐to‐Iron Molar Ratios in Common Bean

Plant, Cell &Environment, Volume 49, Issue 7, Page 4152-4165, July 2026.
ABSTRACT Although significant advances have been achieved in the biofortification of common beans to overcome deficiencies in Zinc (Zn) and iron (Fe), the mechanisms involved remain poorly understood. We thus explored the relationships between phosphorus nutrition and Zn and Fe accumulation in four bean genotypes (Edar, Nizok, Colorado and Chimbolos ...
