Abstract
Ischemic brain injury is implicated in the pathophysiology of stroke and brain trauma, which are among the top killers worldwide, and intensive studies have been performed to reduce neural cell death after cerebral ischemia. Alpha 2- adrenergic agonists have been shown to improve the histomorphological and neurological outcome after cerebral ischemic injury when administered during ischemia, and recent studies have provided considerable evidence that alpha 2-adrenergic agonists can protect the brain from ischemia/reperfusion injury. Thus, alpha 2-adrenergic agonists are promising potential drugs in preventing cerebral ischemic injury, but the mechanisms by which alpha 2-adrenergic agonists exert their neuroprotective effect are unclear. Activation of both the alpha 2-adrenergic receptor and imidazoline receptor may be involved. This mini review examines the recent progress in alpha 2-adrenergic agonists - induced neuroprotection and its proposed mechanisms in cerebral ischemic injury.

Advances in Neuroinflammation and Neuroprotection: Mechanisms and Therapeutic Frontiers
It offers a comprehensive exploration of neuroinflammatory and neuroprotective pathways that play central roles in a range of neurological disorders, including stroke, traumatic brain injury, and neurodegenerative diseases such as Alzheimer’s and Parkinson’s. This issue invites research on the cellular and molecular mechanisms driving neuroinflammation, such as the roles of ...read more
Advances in paediatric and adult brain cancers: emerging targets and treatments
Brain tumors are the most common solid tumors affecting children and adolescents, with up to 5,000 children diagnosed per year. Pediatric brain tumors, because of their location, are often untreatable and their clinical management can cause significant long-term impairment to intellectual and neurological function with epilepsy and neurodegeneration. Other than ...read more
Emotion (Dys)regulation: An integration of Pharmacological, Neurobiological, and Psychological Frameworks
Emotion regulation is a critical aspect of mental well-being and interpersonal relationships. To fully understand and effectively address emotion regulation, an integrative approach that considers pharmacological, neurobiological, and psychological frameworks is essential. Pharmacological interventions, such as medications targeting neurotransmitter imbalances, can play a significant role in managing emotional dysregulation. Understanding ...read more
Enhancing Neuropharmacology with Home Cage Monitoring, Advanced Delivery and Stimulation Technologies, and Artificial Intelligence
Home cage monitoring (HCM) technologies have revolutionized neuropharmacological research by enabling continuous, non-invasive observation of rodents in their natural environments. Complementary advancements such as 24/7 continuous drug delivery systems (e.g., implantable pumps) and wireless neurostimulation methods—including optogenetics—offer precise methods for modulating neural activity and administering pharmacological agents without disrupting the ...read more
