Coexistence of Competing Microbial Strains under Twofold Environmental Variability and Demographic Fluctuations [PDF]
New J. Phys 25, 123010 (2023), 2023 Microbial populations generally evolve in volatile environments, under conditions fluctuating between harsh and mild, e.g. as the result of sudden changes in toxin concentration or nutrient abundance. Environmental variability thus shapes the long-time population dynamics, notably by influencing the ability of different strains of microorganisms to ...

From Bacterial Poisons to Toxins: The Early Works of Pasteurians
Toxins, 2022 We review some of the precursor works of the Pasteurians in the field of bacterial toxins. The word “toxin” was coined in 1888 by Ludwig Brieger to qualify different types of poison released by bacteria.

Molecular Aspects of Secretory Granule Exocytosis by Neurons and Endocrine Cells [PDF]
, 1994 Neuronal communication and endocrine signaling are fundamental for integrating the function of tissues and cells in the body. Hormones released by endocrine cells are transported to the target cells through the circulation.

Structural and functional substrates of tetanus toxin in an animal model of temporal lobe epilepsy
Brain Structure and Function, 2014 The effects of tetanus toxin (TeNT) both in the spinal cord, in clinical tetanus, and in the brain, in experimental focal epilepsy, suggest disruption of inhibitory synapses.

Epileptic high-frequency network activity in a model of non-lesional temporal lobe epilepsy [PDF]
, 2010 High-frequency cortical activity, particularly in the 250–600 Hz (fast ripple) band, has been implicated in playing a crucial role in epileptogenesis and seizure generation. Fast ripples are highly specific for the seizure initiation zone.

Loss of AP-3 function affects spontaneous and evoked release at hippocampal mossy fiber synapses [PDF]
Proc Natl Acad Sci U S A (20/10/2006) sous presse, 2006 Synaptic vesicle (SV) exocytosis mediating neurotransmitter release occurs spontaneously at low intraterminal calcium concentrations and is stimulated by a rise in intracellular calcium. Exocytosis is compensated for by the reformation of vesicles at plasma membrane and endosomes.

The light chain but not the heavy chain of botulinum A toxin inhibits exocytosis from permeabilized adrenal chromaffin cells [PDF]
, 1989 The heavy and light chains of botulinum A toxin were separated by anion exchange chromatography. Their intracellular actions were studied using bovine adrenal chromaffin cells permeabilized with streptolysin O.
