Wakefulness affects synaptic and network activity by increasing extracellular astrocyte-derived adenosine [PDF]

, 2012
Loss of sleep causes an increase in sleep drive and deficits in hippocampal-dependent memory. Both of these responses are thought to require activation of adenosine A1 receptors (adorA1Rs) and release of transmitter molecules including ATP, which is ...

Broth depending production of extracellular enzymes by enterobacteria isolated from dairy food (Serbian cheese) [PDF]

Kragujevac Journal of Science, 2020
In this paper, we investigated, for the first time, the enzyme activity of enterobacteria from cheese from Southeastern Serbia (Sokobanja), which was produced in a traditional way.

Stronger microbial nutrient limitations in subsoil along the precipitation gradient of agroecosystem: insights from soil enzyme activity and stoichiometry

Frontiers in Ecology and Evolution, 2023
IntroductionSoil extracellular enzymes are central in terrestrial ecosystem responses to climate change, and their research can be crucial for assessing microbial nutrient demand.

Neutrophil extracellular traps in inflammatory disorders [PDF]

, 2014
A novel feature of polymorphonuclear granulocyte (PMN) biology is their ability to generate neutrophil extracellular traps (NETs) via a distinct process of cell death termed NETosis.

Development of antigen-specific ELISA for circulating autoantibodies to extracellular matrix protein 1 in lichen sclerosus [PDF]

, 2004
Lichen sclerosus is a common, acquired chronic inflammatory skin disease of unknown etiology, although circulating autoantibodies to the glycoprotein extracellular matrix protein 1 (ECM1) have been detected in most patients’ sera.

Field and lab conditions alter microbial enzyme and biomass dynamics driving decomposition of the same leaf litter

Frontiers in Microbiology, 2013
Fluctuations in climate and edaphic factors influence field decomposition rates and preclude a complete understanding of how microbial communities respond to plant litter quality. In contrast, laboratory microcosms isolate the intrinsic effects of litter

Bacterial Tradeoffs in Growth Rate and Extracellular Enzymes

Frontiers in Microbiology, 2019
Like larger organisms, bacteria possess traits, or phenotypic characteristics, that influence growth and impact ecosystem processes. Still, it remains unclear how these traits are organized across bacterial lineages.

Soil degradation regulates the effects of litter decomposition on soil microbial nutrient limitation: Evidence from soil enzymatic activity and stoichiometry

Frontiers in Plant Science, 2023
Soil microorganisms could obtain energy and nutrients during litter decomposition with the help of soil extracellular enzymes. The litter types were among the most critical factors that affect soil extracellular enzyme activities.

Extracellular Matrix Enzymes and Immune Cell Biology [PDF]

Frontiers in Molecular Biosciences, 2021
Remodelling of the extracellular matrix (ECM) by ECM metalloproteinases is increasingly being associated with regulation of immune cell function. ECM metalloproteinases, including Matrix Metalloproteinases (MMPs), A Disintegrin and Metalloproteinases (ADAMs) and ADAMs with Thombospondin-1 motifs (ADAMTS) play a vital role in pathogen defence and have ...

Impact of Trametes versicolor and Phanerochaete chrysosporium on differential breakdown of pesticide mixtures in soil microcosms at two water potentials and associated respiration and enzyme activity. [PDF]

, 2008
This study has examined the effect of inoculation of soil microcosms with Trametes versicolor and Phanerochaete chrysosporium on wood chips on differential degradation of pesticides (simazine, trifluralin and dieldrin, 10 mg kg−1 soil) at two water ...
