Molecular mechanisms driving homeostatic plasticity of neurotransmitter release

open access: yesFrontiers in Cellular Neuroscience, 2013
Homeostatic plasticity is a process by which neurons adapt to the overall network activity to keep their firing rates in a reasonable range. At the cellular level this kind of plasticity comprises modulation of cellular excitability and tuning of ...

Control of neurotransmitter release by two distinct membrane-binding faces of the Munc13-1 C1C2B region

open access: yeseLife, 2021
Munc13-1 plays a central role in neurotransmitter release through its conserved C-terminal region, which includes a diacyglycerol (DAG)-binding C1 domain, a Ca2+/PIP2-binding C2B domain, a MUN domain and a C2C domain.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Molecular mechanisms that stabilize short term synaptic plasticity during presynaptic homeostatic plasticity. [PDF]

open access: yes, 2018
Presynaptic homeostatic plasticity (PHP) compensates for impaired postsynaptic neurotransmitter receptor function through a rapid, persistent adjustment of neurotransmitter release, an effect that can exceed 200%.

Discriminating depression, physical and social anhedonia by neurotransmitter related challenge tests [PDF]

open access: yes, 2016
The aim of this study was to investigate, if anhedonia, a salient component of depression, shows similar response patterns to neurotransmitter challenge tests as depression, and if the two questionnaire based components Physical (PA) and Social (SA ...

Dynamic control of neurotransmitter release by presynaptic potential

open access: yesFrontiers in Cellular Neuroscience, 2016
Action potentials in the mammalian brain are thought to represent the smallest unit of information transmitted by neurons to their postsynaptic targets. According to this view, neuronal signaling is all-or-none or digital.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Key determinants of the dual clamp/activator function of Complexin

open access: yeseLife
Complexin determines magnitude and kinetics of synchronized secretion, but the underlying molecular mechanisms remained unclear. Here, we show that the hydrophobic face of the amphipathic helix at the C-terminus of Complexin II (CpxII, amino acids 115 ...

NKCC1: A key regulator of glioblastoma progression

open access: yesMolecular Oncology, EarlyView.
Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

Imaging striatal dopamine release using a nongenetically encoded near infrared fluorescent catecholamine nanosensor. [PDF]

open access: yes, 2019
Neuromodulation plays a critical role in brain function in both health and disease, and new tools that capture neuromodulation with high spatial and temporal resolution are needed.
