Connexin hemichannels: novel mediators of toxicity [PDF]

Archives of Toxicology, 2014
Tissue homeostasis is driven by a myriad of extracellular, intracellular and intercellular signaling networks. Direct communication between neighboring cells is typically controlled by gap junctions (Decrock et al. 2009; Nielsen et al. 2012; Vinken et al. 2011).

Macrophage‐Fibroblast Crosstalk Shapes Wound Repair Signaling In Vitro

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
Intercellular communication between macrophages and fibroblasts is critical for wound healing. Macrophages promoted fibroblast scratch closure through contact‐dependent mechanisms independent of connexins. In contrast, fibroblasts regulated macrophage cytokine secretion via connexin‐43–mediated contact signaling that increased IL10 and paracrine ...

The Neuroglial Dialog Between Cannabinoids and Hemichannels [PDF]

Frontiers in Molecular Neuroscience, 2018
The formation of gap junctions was initially thought to be the central role of connexins, however, recent evidence had brought to light the high relevance of unopposed hemichannels as an independent mechanism for the selective release of biomolecules during physiological and pathological conditions.

Inhibition of astroglial hemichannels prevents synaptic transmission decline during spreading depression

Biological Research
Background Spreading depression (SD) is an intriguing phenomenon characterized by massive slow brain depolarizations that affect neurons and glial cells.

Neuronal involvement in muscular atrophy

Frontiers in Cellular Neuroscience, 2014
The innervation of skeletal myofibers exerts a crucial influence on the maintenance of muscle tone and normal operation. Consequently, denervated myofibers manifest atrophy, which is preceded by an increase in sarcolemma permeability.

Glucose metabolic reprogramming as a driver of immunosuppression in the tumour microenvironment

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.
Glucose metabolic reprogramming is a central driver of immunosuppression in the tumour microenvironment, orchestrating immune dysfunction through multiple interconnected mechanisms. Glucose competition establishes a selective bioenergetic hierarchy that constrains antitumour immunity, whereas lactate accumulation and its reciprocal crosstalk with ...

Electrophysiology of Single and Aggregate Cx43 Hemichannels

PLoS ONE, 2012
Connexin43 (Cx43) is the most ubiquitous gap junction protein in the human body and is essential for cell-to-cell communication in a variety of organs and organ systems. As a result, Cx43 is responsible for mediating both electrical and chemical signals, passing dissolved solutes and small signaling molecules between cells in a coordinated fashion ...

A Cationic Block Co‐Polymer for Gene Delivery in the Posterior Segment of the Eye

Journal of Biomedical Materials Research Part A, Volume 114, Issue 5, May 2026.
ABSTRACT Diseases of the back of the eye such as neovascular age‐related macular degeneration (nAMD) are vision threatening and treatment is burdensome for patients, often requiring ocular injections every other month. Injection risks and logistics lower patient compliance; however, even patients receiving optimal treatment can deteriorate.

Hemichannels: new roles in astroglial function

Frontiers in Physiology, 2014
The role of astrocytes in brain function has evolved over the last decade, from support cells to active participants in the neuronal synapse through the release of gliotransmitters.

Connexin Regulation and Modulation of Neural Stem Cell Differentiation Induced by Cell‐Permeable Itaconate

Journal of Cellular Physiology, Volume 241, Issue 5, May 2026.
The immunometabolite itaconate modulates the connexin profile of neural stem cells, and it upregulates Cx36‐based channels, promoting the differentiation toward a neuronal phenotype. These effects were abolished by connexin blockade, supporting a role for itaconate in the neuroimmune axis in inflammatory and neurodegenerative disorders. ABSTRACT Neural
