As the global aging problem intensifies, the incidence of neurodegenerative diseases (such as Alzheimer’s Disease, AD) is increasing year by year. Brain aging (Brain Aging, BA) is one of the significant risk factors for neurodegenerative diseases, but it does not completely align with chronological age (Chronological Age, CA). Traditional methods f...

Detrimental influence of Arginase-1 in infiltrating macrophages on poststroke functional recovery and inflammatory milieu

Medicine, Neurology, Life Sciences, Biochemistry, Immunology,
 

The Detrimental Role of Arginase-1 in Macrophages After Ischemic Stroke Academic Background Ischemic stroke remains one of the leading causes of long-term disability worldwide. Although arginase-1 (Arg1) is typically associated with anti-inflammatory responses and tissue repair, its specific role in post-stroke recovery remains unclear. Arg1 is pre...
