Molecular mechanisms of atherosclerosis: role of connexins

open access: yes, 2012
Atherosclerosis is an immuno-inflammatory disease of arteries, involving complex intercellular interactions. Direct communication through hemichannels and gap junction channels formed by connexins is important in atherosclerosis.

SnapShot: Connexins and Disease

open access: yesCell, 2017
The connexin family of membrane proteins enable gap junction formation and homeostasis, supporting communication between adjacent cells. This SnapShot highlights mutations in different connexins associated with human pathologies and how they affect gap junction function.

Connexins as therapeutic targets in neurological and neuropsychiatric disorders

open access: yes, 2021
Astrocytes represent the reticular part of the central nervous system; gap junctions formed by connexins Cx43, Cx30- and Cx26 provide for homocellular astrocyte-astrocyte coupling, whereas connexins Cx30, Cx32, Cx43, and Cx47 connect astrocytes and ...

AMPK‐mediated prevention of vascular dysfunction with metformin: Experimental and population‐based evidence

open access: yesBritish Journal of Pharmacology, EarlyView.
Angiotensin II induces vascular inflammation, senescence, extracellular matrix (ECM) degradation and endothelial dysfunction, thus impairing SK+/IK+ channel function and reducing endothelial‐dependent hyperpolarisation (EDH). Metformin activates AMPK, increasing SK+/IK+ channel function and restoring vasorelaxation.

Tunnelling Nanotube‐Mediated Lysosome Sharing Promotes Osteocyte Survival via Transcellular Autophagy

open access: yesCell Proliferation, EarlyView.
This study provides the first definitive identification of tunnelling nanotubes (TNTs) between cultured osteocytes and shows TNT‐mediated lysosome transfer from healthy to stressed cells, restoring autophagic flux and preventing apoptosis. This discovery of transcellular autophagy reveals a new survival mechanism in osteocytes, offering potential ...

Pannexin 1 Is Critically Involved in Feedback from Horizontal Cells to Cones

open access: yesFrontiers in Molecular Neuroscience, 2017
Retinal horizontal cells (HCs) feed back negatively to cone photoreceptors and in that way generate the center/surround organization of bipolar cell receptive fields. The mechanism by which HCs inhibit photoreceptors is a matter of debate.

Regulation of cardiovascular connexins by mechanical forces and junctions

open access: yes, 2017
Connexins form a family of transmembrane proteins that consists of 20 members in humans and 21 members in mice. Six connexins assemble into a connexon that can function as a hemichannel or connexon that can dock to a connexon expressed by a neighbouring ...

Regulation of connexin expression

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2005
Gap junctions contain cell-cell communicating channels that consist of multimeric proteins called connexins and mediate the exchange of low-molecular-weight metabolites and ions between contacting cells. Gap junctional communication has long been hypothesized to play a crucial role in the maintenance of homeostasis, morphogenesis, cell differentiation,

Mitochondrial transfer in acute myeloid leukaemia and multiple myeloma: Mechanisms, consequences and potential therapeutic opportunities

open access: yesThe FEBS Journal, EarlyView.
Mitochondria can be transferred from bone marrow cells to cancer cells in acute myeloid leukaemia and multiple myeloma, boosting tumour energy production, growth, and drug resistance. This review highlights key transfer mechanisms and shows how targeting mitochondrial movement and dynamics may offer new therapeutic strategies to limit cancer ...
