Impairing one sensory modality enhances another by reconfiguring peptidergic signalling in Caenorhabditis elegans [PDF]
Animals that lose one sensory modality often show augmented responses to other sensory inputs. The mechanisms underpinning this cross-modal plasticity are poorly understood. We probe such mechanisms by performing a forward genetic screen for mutants with

E. coli infection disrupts the epithelial barrier and activates intrinsic neurosecretory reflexes in the pig colon [PDF]
This study aims to assess the barrier integrity and possible activation of enteric neural pathways associated with secretion and motility in the pig colon induced by an enterotoxigenic Escherichia coli (ETEC) challenge.

V-ATPase modulates exocytosis in neuroendocrine cells through the activation of the ARNO-Arf6-PLD pathway and the synthesis of phosphatidic acid [PDF]
Although there is mounting evidence indicating that lipids serve crucial functions in cells and are implicated in a growing number of human diseases, their precise roles remain largely unknown.

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 ...

The Role of Vti1a in Biological Functions and Its Possible Role in Nervous System Disorders [PDF]
Vesicle transport through interaction with t-SNAREs 1A (Vti1a), a member of the N-ethylmaleimide-sensitive factor attachment protein receptor protein family, is involved in cell signaling as a vesicular protein and mediates vesicle trafficking.

Presynaptic Acetylcholine Receptors Modulate the Time Course of Action Potential-Evoked Acetylcholine Quanta Secretion at Neuromuscular Junctions [PDF]
For effective transmission of excitation in neuromuscular junctions, the postsynaptic response amplitude must exceed a critical level of depolarization to trigger action potential spreading along the muscle-fiber membrane.

The Role of Nicotinic Receptors on Ca2+ Signaling in Bovine Chromaffin Cells [PDF]
Chromaffin cells have been used as a physiological model to understand neurosecretion in mammals for many years. Nicotinic receptors located in the cells’ membrane are stimulated by acetylcholine, and they participate in the exocytosis of chromaffin ...

Brevenal inhibits pacific ciguatoxin-1B-induced neurosecretion from bovine chromaffin cells.
Ciguatoxins and brevetoxins are neurotoxic cyclic polyether compounds produced by dinoflagellates, which are responsible for ciguatera and neurotoxic shellfish poisoning (NSP) respectively. Recently, brevenal, a natural compound was found to specifically

Substance P immunoreactivity exhibits frequent colocalization with kisspeptin and neurokinin B in the human infundibular region. [PDF]
Neurons synthesizing neurokinin B (NKB) and kisspeptin (KP) in the hypothalamic arcuate nucleus represent important upstream regulators of pulsatile gonadotropin-releasing hormone (GnRH) neurosecretion.
