Statins are highly effective and widely prescribed cholesterol lowering drugs. However, statins cross the blood-brain barrier decrease neural in animal models, raising concern that long-term statin use may impact cholesterol-dependent structures functions brain. Cholesterol is a fundamental component of cell membranes experimentally decreasing membrane has been shown to alter morphology vitro. In addition, brain regions undergo adult neurogenesis rely on local for manufacture new neuronal membranes. Thus be particularly vulnerable use. Here we asked whether oral treatment impacts juveniles, either by numbers cells formed or altering structure neurons. The children adolescents received less attention than older adults, with few studies potential unintended effects young brains.

Astrocytes play a pivotal role in maintaining brain energy homeostasis, supporting neuronal function through glycolysis and lipid metabolism. This review explores the metabolic intricacies of astrocytes both physiological pathological conditions, highlighting their adaptive plasticity diverse functions. Under normal modulate synaptic activity, recycle neurotransmitters, maintain blood–brain barrier, ensuring balanced supply protection against oxidative stress. However, response to central nervous system pathologies such as neurotrauma, stroke, infections, neurodegenerative diseases like Alzheimer’s Huntington’s disease, undergo significant morphological, molecular, changes. Reactive upregulate fatty acid oxidation meet increased demands, which can be protective acute settings but may exacerbate chronic inflammation disease progression. emphasizes need for advanced genetic, tools further understand astrocyte heterogeneity reprogramming states.

Major depressive disorder (MDD) is a common mental with chronic tendencies that seriously affect regular work, life, and study. However, its exact pathogenesis remains unclear. Patients MDD experience systemic localized impairments in glucose metabolism throughout the disease course, disrupting various processes such as uptake, glycoprotein transport, glycolysis, tricarboxylic acid cycle (TCA), oxidative phosphorylation (OXPHOS). These may result from mechanisms including insulin resistance, hyperglycemia-induced damage, stress, astrocyte abnormalities, mitochondrial dysfunction, leading to insufficient energy supply, altered synaptic plasticity, neuronal cell death, functional structural damage reward networks. mechanical changes contribute of severely interfere prognosis. Herein, we summarized impairment pathophysiological patients MDD. In addition, briefly discussed potential pharmacological interventions for alleviate MDD, glucagon-like peptide-1 receptor agonists, metformin, topical insulin, liraglutide, pioglitazone, encourage development new therapeutics.

Ischemic stroke, a leading cause of disability and mortality worldwide, is characterized by the sudden loss blood flow in specific area brain. Intravenous thrombolysis with recombinant tissue plasminogen activator only approved pharmacological treatment for acute ischemic stroke; however, aforementioned has significant clinical limitations, thus there an urgent need development novel mechanisms therapeutic strategies stroke. Astrocytes, abundant versatile cells central nervous system, offer crucial support to neurons nutritionally, structurally physically. They also contribute blood‑brain barrier formation regulate neuronal extracellular ion concentrations. Accumulated evidence revealed involvement astrocytes regulation host neurotransmitter metabolism, immune response repair, different metabolic characteristics can process suggesting that targeted astrocyte reprogramming may prognosis In present review, current understanding multifaceted along its regulatory factors pathways, as well promote polarization balance, which hold promise immunometabolism‑targeted therapies were summarized.

The regulation of energy in the brain has garnered substantial attention recent years due to its significant implications various disorders and aging. brain's metabolism is a dynamic tightly regulated network that balances demand supply by engaging complementary molecular pathways. crosstalk among these pathways enables system switch preferred fuel source based on substrate availability, activity levels, cell state-related factors such as redox balance. Brain production relies multi-cellular cooperation continuously supplied from blood limited internal stores. Astrocytes, which interface with neurons vessels, play crucial role coordinating metabolic activity, their dysfunction can have detrimental effects health. This review characterizes major substrates (glucose, lactate, glycogen, ketones lipids) astrocyte health, focusing developments field.

Phospholipase D (PLD) is an enzyme that consists of six isoforms (PLD1–PLD6) and has been discovered in different organisms including bacteria, viruses, plants, mammals. PLD involved regulating a wide range nerve cells’ physiological processes, such as cytoskeleton modulation, proliferation/growth, vesicle trafficking, morphogenesis, development. Simultaneously, PLD, which also plays essential role the pathogenesis neurodegenerative neuroimmune diseases. In this review, family members, characterizations, structure, functions related signaling pathways, therapeutic values was summarized, then five representative diseases Alzheimer disease (AD), Parkinson’s (PD), etc. were selected examples to tell involvement these neurological Notably, recent advances development tools for studying therapy envisaged novel interventions.

Obesity, type 2 diabetes (T2D), and Alzheimer's disease (AD) are pathologies that affect millions of people worldwide. They have no effective therapy difficult to prevent control when they develop. It has been known for many years these diseases pathogenic aspects in common. We highlight this review neuroglial cells (astroglia, oligodendroglia, microglia) play a vital role the origin, clinical-pathological development, course brain neurodegeneration. Moreover, we include new results T2D-AD mouse model (APP+PS1 mice on high-calorie diet) investigating.
