Chronic migraine (CM) is a disabling neurological disease. Astragaloside IV (AS-IV), a natural product derived from Astragalus membranaceus, shows great potential in treating chronic pain by relieving inflammation and oxidative stress. This study aimed to investigate the effects and mechanisms of action of AS-IV on CM.

Priego and colleagues identify a secreted glycoprotein TIMP1, expressed downstream of the transcription factor STAT3, in a subpopulation of STAT3+ reactive astrocytes as a mediator of immunosuppression in late-stage brain metastases. The STAT3 inhibitor silibinin enhances the preclinical efficacy of the combined PD-1/CTLA4 immune checkpoint blockade, providing a rationale to translate the combination therapy into clinical use for this underserved patient group with poor prognosis. See related article by Priego et al.

Alzheimer's Disease (AD) is a chronic neurodegenerative disorder characterized by the accumulation of toxic amyloid-beta (Aβ) plaques and neurofibrillary tangles (NFTs) of tau protein in the brain. Microglia, key immune cells of the central nervous system, play an important role in AD development and progression, primarily through their responses to Aβ and NFTs. Initially, microglia can clear Aβ, but in AD, chronic activation overwhelms protective mechanisms, leading to sustained neuroinflammation that enhances plaque toxicity, setting off a damaging cycle that affects neurons, astrocytes, cerebral vasculature, and other microglia.

Currently, research on optic nerve injury predominantly focuses on the retina and optic nerve, but emerging evidence suggests that optic nerve injury also affects advanced visual structures like the superior colliculus (SC) and primary visual cortex (V1 region). However, the exact mechanisms have not been fully explored. This study aims to investigate the characteristics and mechanisms of pathology in the SC and V1 region after optic nerve crush (ONC) to deepen our understanding of the central mechanism of visual injury.

Neurodegenerative diseases are characterized by progressive loss of neurons and persistent inflammation. Neurons are terminally differentiated cells, and lost neurons cannot be replaced since neurogenesis is restricted to only two neurogenic niches in the adult brain, whose neurogenic potential decreases with age. In this regard, the astrocytes reprogramming into neurons may represent a promising strategy for restoring the lost neurons and rebuilding neural circuits.
