Možganski edem se pojavi pri različnih patologijah možganov (npr. možganske poškodbe, ishemije, okužbe) in lahko privede do hudih okvar možganov, tudi smrti. Zanj je značilno prekomerno kopičenje vode v znotrajceličnem in zunajceličnem prostoru, ki je posledica porušene ionske homeostaze, predvsem i ...

Oznake:
astrocytes;aerobic glycolysis;d-glucose;
Astroglial aerobic glycolysis, a process during which d-glucose is converted to l-lactate, a brain fuel and signal, is regulated by the plasmalemmal receptors, including adrenergic receptors (ARs) and purinergic receptors (PRs), modulating intracellular Ca2+ and cAMP signals. However, the extent to ...

Most cases of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) have cytoplasmic inclusions of TAR DNA-binding protein 43 (TDP-43) in neurons and non-neuronal cells, including astrocytes, which metabolically support neurons with nutrients. Neuronal metabolism largely depends on t ...

astrocytes;dopamine;volumen transmitter;cyclic AMP;L-lactate;energy metabolism;
Astrocytes maintain homeostasis of the central nervous system and supply neurons with metabolic substrates essential for synaptic plasticity and learning. Upon stimulation by noradrenaline (NA), released primarily by locus coeruleus (LC) neurons and acting via volume transmission, astrocytes enhance ...

Drosophila;Ca2+ excitability;astrocytes;neuromodulator;neurons;octopamine;stress response;
Aim: Octopamine in the Drosophila brain has a neuromodulatory role similar to that of noradrenaline in mammals. After release from Tdc2 neurons, octopamine/tyramine may trigger intracellular Ca2+ signaling via adrenoceptor-like receptors on neural cells, modulating neurotransmission. Octopamine/tyra ...

Oznake:
astrocytes;ketamine;cholesterol;
Ketamine is an antidepressant with rapid therapeutic onset and long-lasting effect, although the underlying mechanism(s) remain unknown. Using FRET-based nanosensors we found that ketamine increases [cAMP]i in astrocytes. Membrane capacitance recordings, however, reveal fundamentally distinct mechan ...

Oznake:
astrocytes;vesicles;confocal microscopy;
The plasticity of astrocytes is fundamental for their principal function, maintaining homeostasis of the central nervous system throughout life, and is associated with diverse exposomal challenges. Here, we used cultured astrocytes to investigate at subcellular level basic cell processes under contr ...

G-protein-coupled receptors (GPCRs) represent a family with over 800 members in humans, and one-third of these are targets for approved drugs. A large number of GPCRs have unknown physiologic roles. Here, we investigated GPR27, an orphan GPCR belonging to the family of super conserved receptor expre ...

Oznake:
astrocytes;stress stimuli;metabolism;
When the brain is in a pathological state, the content of lipid droplets (LDs), the lipid storage organelles, is increased, particularly in glial cells, but rarely in neurons. The biology and mechanisms leading to LD accumulation in astrocytes, glial cells with key homeostatic functions, are poorly ...
