Research progress on the role of inflammatory mediators in the pathogenesis of epilepsy

open access: yesIbrain, Volume 11, Issue 1, Page 44-58, Spring 2025.
In the central nervous system, activated immune cells lead to the overproduction of inflammatory mediators through the corresponding signal pathway. Under the stimulation of inflammatory factors, neuroinflammation ultimately occurs. Overexpression of inflammatory mediators and activated immunocytes plays an important role in the emergence and ...

Glucosamine-mediated immunomodulation after stroke is sexually dimorphic

open access: yesBrain, Behavior, & Immunity - Health, 2020
Growing evidence suggests that galectin-3 (Gal-3) is instrumental in orchestrating innate immune response and microglia activation following different brain pathologies. However, its role remains controversial. We recently showed that a readily available

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

open access: yesMacromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...
