A sequential vesicle pool model with a single release sensor and a Ca(2+)-dependent priming catalyst effectively explains Ca(2+)-dependent properties of neurosecretion. [PDF]
Neurotransmitter release depends on the fusion of secretory vesicles with the plasma membrane and the release of their contents. The final fusion step displays higher-order Ca(2+) dependence, but also upstream steps depend on Ca(2+).

Neurosecretion Competence [PDF]
The phenotype of neurosecretory cells is characterized by clear vesicles and dense granules, both discharged by regulated exocytosis. However, these organelles are lacking completely in a few neurosecretion-incompetent clones of the pheochromocytoma PC12

A TRPV channel modulates C. elegans neurosecretion, larval starvation survival, and adult lifespan. [PDF]
For most organisms, food is only intermittently available; therefore, molecular mechanisms that couple sensation of nutrient availability to growth and development are critical for survival. These mechanisms, however, remain poorly defined.

REST-governed gene expression profiling in a neuronal cell model reveals novel direct and indirect processes of repression and up-regulation. [PDF]
The role of REST changes in neurons, including the rapid decrease of its level during differentiation and its fluctuations during many mature functions and diseases, is well established. However, identification of many thousand possible REST-target genes,

Ependymal and Neural Stem Cells of Adult Molly Fish (Poecilia sphenops, Valenciennes, 1846) Brain: Histomorphometry, Immunohistochemical, and Ultrastructural Studies [PDF]
This study was conducted on 16 adult specimens of molly fish (Poecilia sphenops) to investigate ependymal cells (ECs) and their role in neurogenesis using ultrastructural examination and immunohistochemistry.

Designing New Natural-Mimetic Phosphatidic Acid: A Versatile and Innovative Synthetic Strategy for Glycerophospholipid Research. [PDF]
We report the role of the fatty acyl chains in biological activities of phosphatidic acids (PA). Several PA probes having two different fatty acyl chains were synthesized through a multi‐steps synthesis and bearing various fluorophores or photo‐cross‐linkers (PCL).

Aluminum Exposure Impairs Electrochemically Measured Vesicular Storage and Exocytosis via Iron Homeostasis Dysregulation. [PDF]
Al3+ competes with Fe3+ for transferrin (Tf) binding and enters cells via transferrin receptor (TfR)‐mediated endocytosis, disrupting cellular iron homeostasis. Intracellular vesicle impact electrochemical cytometry (IVIEC) and single‐cell amperometry (SCA), which record the oxidation of dopamine, reveal increased neurotransmitter storage and ...
