Abstract
Background: Dementia cases are increasing as the population ages, leading to increased financial costs. Several neuronal diseases including ischemic and hemorrhagic stroke involve cerebrovascular injury or pathophysiology. Cerebrovascular injury is closely tied to blood brain barrier (BBB) disruption. Many studies have shown a significant association between BBB dysfunction and neurological diseases. Therefore, an understanding of the molecular mechanisms which regulate BBB permeability and disruption is essential for establishing future therapeutic strategies to alter dementia disease progression related to cerebrovascular injury, so-called vascular cognitive impairment (VCI). microRNAs (miRs) are small non-coding RNAs that regulate gene expression through targeting of mRNA transcripts. miRs have been implicated in the development and progression of various illnesses, including vascular disease. However, the role of miRs in BBB breakdown or permeability and VCI development has not yet been well clarified.
Method: Research content related to the origins of VCI and the role of the BBB in pathologic development and therapeutic targeting are reviewed, including current relevant animal models. We draw from the published literature regarding microRNA candidates that are associated with modulation of BBB structure and function. Results: In this review, we summarize the current knowledge about VCI, explore the potential role of miRs in BBB breakdown and VCI progression, and identify potential candidate miRs for development of new treatment strategies. Conclusion: miRs constitute a promising novel avenue as future therapeutic options for alteration of both BBB permeability and development of VCI.Keywords: Alzheimer's disease, microRNA, tight junction, vascular cognitive impairment, vascular dementia (VaD).

Advancements in Robotic and AI-based Drug Discovery and Delivery for Neurological Disorders
Neurological disorders, including Alzheimer's disease, Parkinson's disease, epilepsy, and brain tumors, pose significant challenges in drug delivery due to the blood-brain barrier's intricate structure and the complexity of neuronal networks. Traditional drug delivery methods often fall short in reaching therapeutic concentrations within the central nervous system, limiting treatment efficacy and ...read more
Advances of natural products, bio-actives and novel drug delivery system against emerging viral infections
Due to the increasing prevalence of viral infections and the ability of these human pathogens to develop resistance to current treatment strategies, there is a great need to find and develop new compounds to combat them. These molecules must have low toxicity, specific activity and high bioavailability. The most suitable ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Nanoemulsions in cancer therapy
Solid tumors are characterized by leaky vascular structure, defective angiogenesis and high interstitial fluid load, providing opportunities for nanoparticles to preferentially exudate and be retained in tumors. This phenomenon is commonly referred to as the enhanced permeability and retention (EPR) effect, which is considered to be an important reason why ...read more
