Mitochondrial dysfunction plays a central role in the pathogenesis of numerous neurodegenerative diseases, including Parkinson’s, Alzheimer’s, and Huntington’s disease. Brain transfection techniques aimed at modulating mitochondrial genes or delivering therapeutic nucleic acids offer promising avenues to restore mitochondrial function and halt disease progression. However, targeting mitochondria within neurons poses unique challenges due to their subcellular…

Multifunctional nanocarriers that combine gene delivery with imaging capabilities are transforming brain research by enabling simultaneous visualization and manipulation of neural cells. These advanced platforms integrate therapeutic nucleic acids with imaging agents such as fluorescent dyes, magnetic resonance imaging (MRI) contrast materials, or radionuclides, allowing real-time tracking of delivery, distribution, and gene expression in vivo….

Electroporation is a physical transfection method that uses short electrical pulses to transiently permeabilize cell membranes, allowing direct entry of nucleic acids into cells. It has been widely adopted for gene delivery in adult neural tissue due to its efficiency, low immunogenicity, and ability to target localized brain regions without relying on viral vectors. Despite…

Brain endothelial cells form the inner lining of cerebral blood vessels and constitute a crucial component of the blood-brain barrier (BBB). Targeting these cells with therapeutic genes can modulate BBB function, enhance drug delivery, or address vascular pathologies linked to neurological diseases. Nanoparticle-based delivery systems have emerged as promising vehicles for gene transfer to brain…

RNA interference (RNAi) technology has become a powerful tool for silencing oncogenes and therapeutic targets in brain tumor research. By delivering small interfering RNA (siRNA) or short hairpin RNA (shRNA) molecules, researchers can specifically downregulate gene expression and investigate tumor biology or test novel treatment strategies. However, achieving efficient and sustained gene silencing in brain…

Calcium phosphate nanoparticles have been explored as a biocompatible and efficient non-viral vector for transfecting brain cells both in vitro and in vivo. Their natural biodegradability, low toxicity, and ability to facilitate endosomal escape make them a promising alternative to viral vectors and synthetic polymers for gene delivery in neural applications. The fundamental mechanism relies…

Magnetofection is an innovative gene delivery technique that utilizes magnetic nanoparticles coupled with nucleic acids, allowing researchers to direct genetic material to specific brain regions using externally applied magnetic fields. This method offers several advantages including enhanced transfection efficiency, spatial targeting, and reduced dosage of genetic material, making it particularly attractive for applications in brain…

The blood-brain barrier (BBB) serves as the major obstacle for delivering genetic material to the brain via systemic routes. Consequently, developing accurate in vitro and ex vivo BBB models is critical for screening and optimizing brain transfection vectors and delivery methods before in vivo studies. Recent advances in BBB modeling have produced more physiologically relevant…

Neural stem cells (NSCs) are pivotal for brain development, repair, and plasticity, making them a prime target for genome editing approaches aimed at understanding gene function or correcting disease mutations. However, delivering CRISPR/Cas9 components effectively and safely into NSCs poses unique challenges due to their quiescent nature, sensitivity to DNA damage, and the need for…

Brain transfection techniques, whether viral or non-viral, introduce foreign genetic material and delivery vehicles into the delicate neural environment. One often overlooked consequence is microglial activation, the brain’s resident immune response, which can significantly influence both experimental outcomes and therapeutic safety. Understanding the mechanisms and impacts of microglial activation is critical for designing brain transfection…
