Summary
Transferrin-modified Rutin liposomes (Tf-Rutin-Lip) were developed to improve Rutin
Area of Science:
- * Pharmacology and Drug Delivery
- * Nanotechnology in Medicine
- * Neuroscience and Neurodegenerative Diseases
Background:
- * Rutin, a flavonoid, shows promise for treating neurological disorders like Alzheimer's disease.
- * Rutin's therapeutic potential is hindered by poor solubility, low bioavailability, and limited blood-brain barrier (BBB) penetration.
- * Liposomes offer a promising delivery system to overcome these limitations.
Purpose of the Study:
- * To develop and characterize transferrin-modified Rutin liposomes (Tf-Rutin-Lip) for enhanced brain targeting.
- * To evaluate the safety and efficacy of Tf-Rutin-Lip in crossing the BBB and improving Rutin's pharmacokinetic profile.
- * To optimize liposome preparation conditions for maximum therapeutic benefit.
Main Methods:
- * Liposomes encapsulating Rutin were prepared using the thin-film dispersion method and optimized via response surface methodology.
- * Transferrin (Tf) was covalently attached to liposomes to create Tf-Rutin-Lip.
- * Toxicity on bEnd.3 cells, BBB tight junction integrity, in vitro/in vivo brain targeting, and pharmacokinetics were assessed.
Main Results:
- * Optimized Tf-Rutin-Lip preparation involved specific lipid ratios, temperature, hydration, sonication, and surfactant concentrations.
- * Tf-Rutin-Lip demonstrated no toxicity to bEnd.3 cells and did not disrupt BBB tight junctions.
- * Tf-Rutin-Lip showed enhanced cellular uptake and BBB penetration, significantly increasing Rutin's Cmax, AUC, and half-life.
Conclusions:
- * Transferrin modification effectively enhances the brain-targeting capability of Rutin-loaded liposomes.
- * Tf-Rutin-Lip exhibits favorable safety profiles and improved pharmacokinetic properties compared to free Rutin.
- * This novel delivery system holds potential for improving Rutin's efficacy in treating brain disorders.

11.4K
Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...

01:19Drug Absorption Mechanism: Carrier-Mediated Membrane Transport
5.7K
Certain large, lipid-insoluble drug molecules that resemble amino acids, peptides, or glucose, require specialized carrier proteins to facilitate their diffusion across cell membranes. This transport can occur through either facilitated diffusion, which does not require energy input, or active transport, which does require energy input.
Facilitated diffusion is a passive process that utilizes human Solute Carrier (SLC) transporters. These transporters bind to the drug, undergo structural...

4.6K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

3.5K
Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
926
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

177
Stimuli-activated drug delivery systems are designed to release drugs in response to specific physical, chemical, or biological stimuli. These systems often utilize hydrogels—three-dimensional, hydrophilic polymer networks capable of swelling in aqueous environments and retaining significant fluid volumes. Upon exposure to particular stimuli, these hydrogels undergo structural transitions that allow the embedded drug to be released. Due to this adaptive behavior, such systems are also...
