Molecular Diffusion through Cyanobacterial Septal Junctions

mBio, 2017
Heterocyst-forming cyanobacteria grow as filaments in which intercellular molecular exchange takes place. During the differentiation of N2-fixing heterocysts, regulators are transferred between cells.

Primary cultures of chick osteocytes retain functional gap junctions between osteocytes and between osteocytes and osteoblasts [PDF]

, 2008
The inaccessibility of osteocytes due to their embedment in the calcified bone matrix in vivo has precluded direct demonstration that osteocytes use gap junctions as a means of intercellular communication.

Dynamic changes in connexin expression correlate with key events in the wound healing process. [PDF]

, 2003
Wound healing is a complex process requiring communication for the precise co-ordination of different cell types. The role of extracellular communication through growth factors in the wound healing process has been extensively documented, but the role of

Gap-junctional coupling between neutrophils and endothelial cells [PDF]

, 2003
Communication between leukocytes and endothelial cells is crucial for inflammatory reactions. Paracrine cross-talk and outside-in signaling (via adhesion molecules) have been characterized as communication pathways to date.

Nitric oxide enhances de novo formation of endothelial gap junctions [PDF]

, 2003
Objective: Gap junctions (formed by connexins, Cx) are important for functional coordination of cells in the vascular wall. However, little is known about their physiological regulation in this tissue.

Gap junctions, dendrites and resonances : a recipe for tuning network dynamics [PDF]

, 2013
Gap junctions, also referred to as electrical synapses, are expressed along the entire central nervous system and are important in mediating various brain rhythms in both normal and pathological states.

Cyanobacterial Septal Junctions: Properties and Regulation

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

Metallothionein 2 activation by pravastatin reinforces epithelial integrity and ameliorates radiation-induced enteropathy

EBioMedicine, 2021
: Background: Radiotherapy or accidental exposure to ionizing radiation causes severe damage of healthy intestinal tissues. Intestinal barrier function is highly sensitive to ionizing radiation, and loss of epithelial integrity results in mucosal ...

Functional implications of calcium permeability of the channel formed by pannexin 1. [PDF]

, 2006
Although human pannexins (PanX) are homologous to gap junction molecules, their physiological function in vertebrates remains poorly understood. Our results demonstrate that overexpression of PanX1 results in the formation of Ca(2+)-permeable gap ...

Regulation of intercellular coupling in acute and chronic heart disease

Brazilian 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 ...
