Abstract
Background: Despite long-standing and worldwide efforts, hemorrhagic stroke remains a critical clinical syndrome that exerts a heavy toll on affected individuals and their families due to the lack of preventive and therapeutic targets.
Objective: To clarify the pathogenesis of hemorrhagic stroke and to identify novel therapeutic targets. Method: Targeting pericytes, the typical mural cells of microvessels, could serve as a way to modulate microvascular permeability, development, and maturation by regulating endothelial cell functions and modulating tissue fibrosis and inflammatory responses. Results: Pericytes in hemorrhagic stroke may exert the following functions: before bleeding, the morphological aberration and dysfunction of pericytes may lead to aneurysm formation, angiopsathyrosis, and hemodynamic disturbances, ultimately causing vasculature rupture. In the acute phase after hemorrhage, pericytes are faced with a complicated bleeding environment, which results in the death of pericytes, blood-brain barrier damage, pericyte-mediated inflammatory cascades, white matter impairment, and ultimately aggravated neural injury. In the recovery period post-hemorrhage, in situ pericytes are activated and differentiate into neurons, glia and endothelial cells to repair the neural vascular network. Moreover, many pericytes are recruited to the lesion and contribute to blood-brain barrier remodeling, thus facilitating neurovascular functional recovery after stroke. Conclusion: Due to the multiple functions of pericytes in the development of vascular rupture and hemorrhagic stroke pathophysiology, additional drugs and trials targeting pericytes and evaluations of their effectiveness are required in future investigations to develop new strategies for the prevention and treatment of hemorrhagic stroke.Keywords: Hemorrhagic stroke, pericytes, prevention, subarachnoid hemorrhage (SAH), therapy, vascular.

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
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
Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...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
