Regulating inflammatory microglia presents a promising strategy for treating neurodegenerative and autoimmune disorders, yet effective therapeutic agents delivery to these cells remains challenge. This study investigates modified lipid nanoparticles (LNP) mRNA hyperactivated microglia, particularly those with pro-inflammatory characteristics, utilizing supervised machine learning (ML) classifiers. We developed screened library of 216 LNP formulations varying compositions, N/P ratios, hyaluronic acid (HA) modifications. The transfection efficiency eGFP was assessed in the BV-2 murine cell line under different immunological states, including resting activated conditions (LPS-activated IL4/IL13-activated). ML-guided morphometric analysis tracked phenotypes various subtypes before after transfection. Four ML classifiers were investigated predict phenotypic changes based on design parameters. Multi-Layer Perceptron (MLP) neural network emerged as best-performing model, achieving weighted F1-scores ≥0.8. While it accurately predicted responses from LPS-activated cells, struggled IL4/IL13-activated cells. MLP model validated by predicting performance four unseen delivering BV2 HA-LNP2 optimal formulation target IL10 mRNA, effectively suppressing phenotypes, evidenced shifts morphology, increased expression, reduced TNF-α levels. also evaluated human iPSC-derived confirming its efficacy modulating responses. highlights potential tailored techniques enhance therapy neuroinflammatory disorders leveraging carrier's immunogenic properties modulate microglial

The selective removal of misfolded, aggregated, or aberrantly overexpressed protein plays an essential role in maintaining protein-dominated biological processes. In parallel, the precise knockout abnormal proteins is inseparable from accurate identification within complex environments. Guided by these precepts, small molecules, antibodies, are commonly used as recognition tools for developing targeted degradation (TPD) technology. Indeed, TPD has shown tremendous prospects chronic diseases, rare cancer research, and other fields. Meanwhile, aptamers short RNA DNA oligonucleotides that can bind to target with high specificity strong affinity. Accordingly, actively designing constructing this perspective, we provide a brief introduction technology its current progress, summarize application challenges. Recent advances aptamer-based reviewed, together corresponding challenges outlooks.

Lipid nanoparticle (LNP)-mediated nucleic acid therapies, including mRNA protein replacement and gene editing hold great potential in treating neurological disorders neurodegeneration, brain cancer, stroke. However, delivering LNPs across the blood-brain barrier (BBB) after systemic administration remains underexplored. In this work, we engineered a high-throughput screening transwell platform for BBB (HTS-BBB), specifically optimized LNPs. Unlike most assays, which only assess transport an endothelial monolayer, HTS-BBB simultaneously measures LNP transfection of cells themselves. We then use to screen library 14 made with structurally diverse ionizable lipids demonstrate it is predictive

Small nucleic acid drugs, composed of nucleotides, represent a novel class pharmaceuticals that differ significantly from conventional small molecule and antibody-based therapeutics. These agents function by selectively targeting specific genes or their corresponding messenger RNAs (mRNAs), further modulating gene expression regulating translation-related processes. Prominent examples within this category include antisense oligonucleotides (ASO), interfering (siRNAs), microRNAs (miRNAs), aptamers. The emergence drugs as focal point in contemporary biopharmaceutical research is attributed to remarkable specificity, facile design, abbreviated development cycles, expansive target spectrum, prolonged activity. Overcoming challenges such poor stability, immunogenicity, permeability issues have been addressed through the integration chemical modifications drug delivery systems. This review provides an overview current status prospective trends development. Commencing with historical context, we introduce primary classifications mechanisms drugs.

Lipid nanoparticles (LNPs) are now highly effective transporters of nucleic acids to the liver. This liver-specificity is largely due their association with certain serum proteins, most notably apolipoprotein E (ApoE), which directs them liver cells by binding low-density lipoprotein (LDL) receptors on hepatocytes. The liver's distinct anatomy, its various specialized cell types, also influences how LNPs taken up from circulation, cleared, and they in delivering treatments. In this review, we consider factors that facilitate LNP's targeting explore latest advances liver-targeted LNP technologies. Understanding targeted can help for design optimization nanoparticle-based therapies. Comprehension cellular interaction biodistribution not only leads better treatments diseases but delivers insight directing other tissues, potentially broadening range therapeutic applications.

Gene therapy holds great promise in the treatment of genetic diseases. It is now possible to make DNA modifications using CRISPR system. However, a major problem remains: delivery these CRISPR-derived technologies specific organs. Lipid nanoparticles (LNPs) have emerged as very promising method. when delivering LNPs intravenously, most cargo trapped by liver. Alternatively, injecting them directly into organs, such brain, requires more invasive procedures. Therefore, developing crucial for their future clinical use. Modifying composition lipids allows deliveries some In this review, we identified effective compositions and proportions target lungs, muscles, heart, liver, spleen, bones.
