These obstacles include the presence of the blood-brain barrier BBB , which restricts the entry of therapeutic agents into the brain, as well as issues related to poor bioavailability and unfavorable pharmacokinetic profiles.

Unfortunately, many therapeutically promising compounds have failed to overcome these hurdles and demonstrate efficacy in treating AD.

Methods: The PEGylated chitosan nanoconjugate was developed and evaluated for delivery of anti-Alzheimer natural extract of Salvia officinalis and Melissa officinalis to the brain. The nano-conjugates S-PCN and M-PCN were developed by ionic gelation technique.

Result: The nanoconjugates S-PCN and M-PCN were evaluated for various optical and in-vitro parameters. MTT assay on UCSDi-SAD human astrocytoma cells indicated IC50 values of 0.

The In vitro assessments using cell lines have confirmed the improved uptake and distribution of nanoconjugates compared to free extracts. These findings were validated through confocal microscopy and apoptosis assays, revealing a substantial increase in the accumulation of nanoconjugates within the brain.

The targeting potential OF M- PCN over S-PCN was found to be 2-fold significant. Conclusion: Based on the findings, it can be inferred that biodegradable PEGylated chitosan nanoconjugates hold promise as effective nano-targeting agents for delivering anti-Alzheimer drugs to the brain.

The incorporation of PEGylated chitosan nanoparticles in this approach demonstrates enhanced delivery capabilities, ultimately leading to improved therapeutic out-comes. Keywords: PEGylation , chitosan , nanoparticles , natural extract , Alzheimer disease , brain targeting.

The authors suggest that as carotenoids offer various health benefits, but their poor solubility and stability present challenges, chitosan-based delivery systems such as nanoemulsions, liposomes, polysaccharide nanoparticles, and nanogels could ensure better carotenoid availability and retention of nutritional value.

Carotenoids are natural compounds found in various organisms and plants but not produced by the human body. Lipid-based systems involve coating nanoemulsions and nanoliposomes with chitosan, while biopolymeric systems use chitosan alone or combined with other polysaccharides to create polysaccharide-based vehicles and biopolymeric nanogels.

The authors report that chitosan-coated nanoemulsions NEs , characterised by small droplet sizes either as oil-in-water or water-in-oil, are a promising method for delivering bioactive molecules.

The authors therefore suggest that water-soluble chitosan coating could be an effective strategy in the food industry to produce β-carotene emulsions with enhanced stability.

The authors report that chitosan-based nanocarriers are also effective in enhancing the stability and bioavailability of poorly soluble bioactive molecules compared to lipid- or protein-based nanocarriers.

These nanoencapsules significantly improved lutein's bioavailability in both in vitro and in vivo tests, with higher lutein levels in the plasma, liver, and eyes of mice compared to non-encapsulated lutein.

Poly ethylene oxide methoxycinnamoylphthaloyl-chitosan PCPLC exhibited high encapsulation and loading efficiency, along with excellent stability at high temperatures.

The researchers used an ionic-gelation method to encapsulate Fx within chitosan dispersed in glycolipid, concluding that the nanoencapsulation improved Fx's bioavailability. Authors: Alessandra Verardi, Paola Sangiorgio, Catia Giovanna Lopresto, Patrizia Casella, and Simona Errico.

In this research, Chitosan Microbeads based 3D scaffolds were optimized and adapted to be integrated onto planar MEAs to study and better understand the functional properties of biomimetic 3D hippocampal networks. Chitosan Microbeads both treated and untreated with adhesion factors were tested.

Whereas, both proved to be reliable supports, able to sustain the neuronal populations during the growth in a 3D space.

In addition, the Chitosan Microbeads provided both a morphological and structural development of a functional network. This research demonstrated that the neuronal network itself was responsible for the assembly and the stabilization of the 3D chitosan based structure.

In conclusion, chitosan seems to be a promising scaffolding-support for developing 3D neuronal networks towards the design and implementation of brain-on-a-chip microsystems. With all this, the Researchers have recently demonstrated that 3D hippocampal networks, made by self-assembled glass microbeads as scaffold, and coupled to micro-electrode arrays MEAs , represent a suitable in vitro model for neurophysiological studies alternative and complementary to the older 2D neuronal network models.

Matrix stiffness and composition are the most critical properties of the 3D system as they can influence growth dynamics, synaptic density, and electrophysiological activity of the neuronal network. In conclusion, a soft porous hydrogel microbeads platform is developed which mimics the physico-chemical characteristics of the Extra Cellular Matrix ECM , for the growth of 3D neuronal networks.

Advanced therapies which combine cells with biomaterial-based carriers are recognized as an emerging and powerful method to treat challenging diseases, such as spinal cord injury SCI. By enhancing transplanted cell survival and grafting, biomimetic hydrogels can be properly engineered to encapsulate cells and locate them at the injured site in a minimally invasive way. Nose-to-brain delivery presents a promising alternative route compared Chitosan for cognitive function classical blood—brain Exceptional ingredient purity passage, especially for the cogniitve of high functioh weight drugs. In general, macromolecules are rapidly degraded in Clear complexion secrets environment. Chitodan, nanoparticulate systems Chitosam be fog to ufnction biomolecules from premature degradation. Chitosan for cognitive function, targeting fynction on the surface of nanoparticles are able to improve bioavailability by enhancing cellular uptake due to specific binding and longer residence time. In this work, transferrin-decorated chitosan nanoparticles are used to evaluate the passage of a model protein through the nasal epithelial barrier in vitro. It was demonstrated that strain-promoted azide—alkyne cycloaddition reaction can be utilized to attach a functional group to both transferrin and chitosan enabling a rapid covalent surface-conjugation under mild reaction conditions after chitosan nanoparticle preparation. The intactness of transferrin and its binding efficiency were confirmed via SDS-PAGE and SPR measurements.
