Damage-induced signalling mechanisms in the neonatal rat cochlea. [PDF]

, 2007
Sound overstimulation and exposure to ototoxic drugs damage cochlear hair cells (HCs) and cause their death. The surrounding support cells maintain an epithelial barrier and the appropriate physiological environment for surviving HCs during pathological ...

Large conductance Ca2+-activated K+ (BK) channel: Activation by Ca2+ and voltage

Biological Research, 2006
Large conductance Ca2+-activated K+ (BK) channels belong to the S4 superfamily of K+ channels that include voltage-dependent K+ (Kv) channels characterized by having six (S1-S6) transmembrane domains and a positively charged S4 domain. As Kv channels, BK

Plasma Gelation as an Overlooked Determinant of Transfection Efficiency in Protein Corona‐Coated Lipid Nanoparticles: Implications for In Vitro–In Vivo Translation

Advanced Healthcare Materials, EarlyView.
Upon contact with plasma, lipid nanoparticles (LNPs) rapidly acquire a protein corona (PC) that redefines their biological identity. In calcium‐containing environments, these coronated particles trigger the formation of a gel‐like plasma network, profoundly altering their transport properties and reducing their effective availability.

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration

Advanced Healthcare Materials, EarlyView.
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...

Swelling-activated Ca2+ channels trigger Ca2+ signals in Merkel cells.

PLoS ONE, 2008
Merkel cell-neurite complexes are highly sensitive touch receptors comprising epidermal Merkel cells and sensory afferents. Based on morphological and molecular studies, Merkel cells are proposed to be mechanosensory cells that signal afferents via ...

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Two-pore channel-2 controls calmodulin-dependent STIM1 inactivation

Nature Communications
Lysosomal two-pore channels (TPC) trigger Ca2+ release from the endoplasmic reticulum (ER). The ensuing ER Ca2+ depletion activates STIM1-gated store-operated Ca2+ entry (SOCE) channels that sustain Ca2+ signals regulating fundamental cellular processes.
