Mitochondria‐associated membranes (MAMs) are contact sites between the endoplasmic reticulum and mitochondria that regulate calcium signaling, lipid metabolism, autophagy, and stress responses. This review outlines their molecular organization, roles in cellular homeostasis, and how dysfunction drives neurodegeneration, metabolic disease, cancer, and ...

Trapping of spermine, Kukoamine A, and polyamine toxin blockers in GluK2 kainate receptor channels
Kainate receptors (KARs) are a subtype of ionotropic glutamate receptor (iGluR) channels, a superfamily of ligand-gated ion channels which mediate the majority of excitatory neurotransmission in the central nervous system. KARs modulate neuronal circuits

One of the most effective medications used for various cardiac diseases and syndromes to improve symptoms and, in some cases, prognosis, are betablockers (BBs) and calcium channel blockers (CCBs).

Voltage-independent SK-channel dysfunction causes neuronal hyperexcitability in the hippocampus of Fmr1 knock-out mice [PDF]
Neuronal hyperexcitability is one of the major characteristics of fragile X syndrome (FXS), yet the molecular mechanisms of this critical dysfunction remain poorly understood. Here we report a major role of voltage-independent potassium (

Blockade of current through single calcium channels by trivalent lanthanide cations. Effect of ionic radius on the rates of ion entry and exit. [PDF]
Currents flowing through single dihydropyridine-sensitive Ca2+ channels were recorded from cell-attached patches on C2 myotubes. In the presence of dihydropyridine agonist to prolong the duration of single-channel openings, adding micromolar ...

Molecular determinants of signal transduction in tropomyosin receptor kinases
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Do beta-blockers prevent heart disease and strokes in people with high blood pressure? Evidence update - Summary of a Cochrane Review [PDF]
In people with high blood pressure, there is no evidence that beta-blockers reduce the number of deaths. Beta-blockers reduce the risk of stroke but are less effective than calcium channel blockers (CCBs) or renin-angiotensin system (RAS ...

Excess Ca2+ ions activate the Calcium‐Sensing Receptor (CaSR), which subsequently drives the uptake of excess inorganic phosphate (Pi) via the Pi transporter (Pit−1) in chondrocytes. This mechanism causes a toxic increase in intracellular Pi concentration, ultimately leading to chondrocyte apoptosis and pathological mineralization. Excess extracellular

Age‐Related Changes in Myeloid Cells and Their Impact on Subcutaneous Melanoma Growth in Mice
Our findings reveal that age‐related changes in subcutaneous melanoma growth and immunotherapy response are context‐dependent. In models where tumor growth and treatment resistance increase with age, this effect is partly driven by enhanced immunosuppression from myeloperoxidase‐active Gr‐1⁺ myeloid cells.
