Cyanobacterial Septal Junctions: Properties and Regulation

open access: yesLife, 2018
Heterocyst-forming cyanobacteria are multicellular organisms that grow as chains of cells (filaments or trichomes) in which the cells exchange regulators and nutrients.

Comparative Analysis of the Major Polypeptides from Liver Gap Junctions and Lens Fiber Junctions [PDF]

open access: yes, 1982
Gap junctions from rat liver and fiber junctions from bovine lens have similar septilaminar profiles when examined by thin-section electron microscopy and differ only slightly with respect to the packing of intramembrane particles in freeze-fracture ...

Regulation of intercellular coupling in acute and chronic heart disease

open access: yesBrazilian Journal of Medical and Biological Research, 2000
Effective pump function of the heart depends on the precise control of spatial and temporal patterns of electrical activation. Accordingly, the distribution and function of gap junction channels are important determinants of the conduction properties of ...

The multifarious regulation of the apical junctional complex [PDF]

open access: yesOpen Biology, 2020
Epithelial cells form highly organized polarized sheets with characteristic cell morphologies and tissue architecture. Cell–cell adhesion and intercellular communication are prerequisites of such cohesive sheets of cells, and cell connectivity is ...

Hydraulic fracturing in cells and tissues: fracking meets cell biology [PDF]

open access: yes, 2017
The animal body is fundamentally made of water. A small fraction of this water is freely flowing in blood and lymph, but most of it is trapped in hydrogels such as the extracellular matrix (ECM), the cytoskeleton, and chromatin.

Adherens, tight, and gap junctions in ependymal cells: A systematic review of their contribution to CSF-brain barrier

open access: yesFrontiers in Neurology, 2023
IntroductionThe movement of fluids and solutes across the ependymal barrier, and their changes in physiologic and disease states are poorly understood.

Regulation of gap junctions by protein phosphorylation

open access: yesBrazilian Journal of Medical and Biological Research, 1998
Gap junctions are constituted by intercellular channels and provide a pathway for transfer of ions and small molecules between adjacent cells of most tissues.

PSD-95 Is Associated with the Postsynaptic Density and Not with the Presynaptic Membrane at Forebrain Synapses [PDF]

open access: yes, 1996
PSD-95, a prominent protein component of the postsynaptic density (PSD) fraction from rat forebrain, has been localized by light microscopy to dendrites of hippocampal neurons (Cho et al., 1992) and to the presynaptic plexus of cerebellar basket cells ...

The structural organization and protein composition of lens fiber junctions. [PDF]

open access: yes, 1989
The structural organization and protein composition of lens fiber junctions isolated from adult bovine and calf lenses were studied using combined electron microscopy, immunolocalization with monoclonal and polyclonal anti-MIP and anti-MP70 (two putative

7-Ketocholesterol modulates intercellular communication through gap-junction in bovine lens epithelial cells

open access: yesCell Communication and Signaling, 2004
Background Connexin43 (Cx43) is an integral membrane protein that forms intercellular channels called gap junctions. Intercellular communication in the eye lens relies on an extensive network of gap junctions essential for the maintenance of lens ...
