Brain extracellular space as a diffusion barrier [PDF]

Computing and Visualization in Science, 2011
The extracellular space (ECS) consists of the narrow channels between brain cells together with their geometrical configuration and contents. Despite being only 20-60 nm in width, the ECS typically occupies 20% of the brain volume. Numerous experiments over the last 50 years have established that molecules moving through the ECS obey the laws of ...

Promotion of Lung Cancer Metastasis by SIRT2‐Mediated Extracellular Protein Deacetylation

Advanced Science, 2023
Acetylation of extracellular proteins has been observed in many independent studies where particular attention has been given to the dynamic change of the microenvironmental protein post‐translational modifications.

Astrocytic Ion Dynamics: Implications for Potassium Buffering and Liquid Flow [PDF]

, 2019
We review modeling of astrocyte ion dynamics with a specific focus on the implications of so-called spatial potassium buffering, where excess potassium in the extracellular space (ECS) is transported away to prevent pathological neural spiking.

Extracellular cysteine in connexins: Role as redox sensors [PDF]

, 2016
Indexación: Scopus.Connexin-based channels comprise hemichannels and gap junction channels. The opening of hemichannels allow for the flux of ions and molecules from the extracellular space into the cell and vice versa.

Extracellular space preservation aids the connectomic analysis of neural circuits

eLife, 2015
Dense connectomic mapping of neuronal circuits is limited by the time and effort required to analyze 3D electron microscopy (EM) datasets. Algorithms designed to automate image segmentation suffer from substantial error rates and require significant ...

Viruses on the Move in the Extracellular Space [PDF]

Plant Physiology, 2019
Positive-strand (+) RNA viruses act as their own messengers, encoding an RNA-dependent RNA polymerase that can replicate their sense RNA genome. This allows (+) RNA viruses to replicate outside the nucleus, within replication complexes formed from host organelle membranes often called ...

Extracellular vimentin is expressed at the rear of activated macrophage-like cells: Potential role in enhancement of migration and phagocytosis

Frontiers in Cell and Developmental Biology, 2022
Macrophages have a vital role in the immune system through elimination of cell debris and microorganisms by phagocytosis. The activation of macrophages by tumour necrosis factor-α induces expression of extracellular cell-surface vimentin and promotes ...

Gastropod-derived haemocyte extracellular traps entrap metastrongyloid larval stages of Angiostrongylus vasorum, Aelurostrongylus abstrusus and Troglostrongylus brevior [PDF]

, 2017
Background: Phagocyte-derived extracellular traps (ETs) were recently demonstrated mainly in vertebrate hosts as an important effector mechanism against invading parasites.

Formation of Extracellular Traps - the Effective Mechanism of Organism Protection from Pathogen

Проблемы особо опасных инфекций, 2012
Summarized and analyzed are modern literature data on capability of cells (neutrophils, eosinophils and labrocytes) realizing the mechanisms of innate immunity, to form extracellular traps that capture and kill pathogens by secretion of DNA and ...
