This pathological process is associated with inflammation and oxidative stress. Proanthocyanidin B2 (PCB2), with its potent antioxidant properties, has been shown to alleviate demyelination in the cuprizone (CPZ) mouse model. It attenuates neuroinflammation and oxidative stress in both the cerebral microenvironment and astrocytes (AS). The xCT\/GSH\/GPX4 axis is a key regulatory pathway for oxidative stress. Therefore, we hypothesize that PCB2 can alleviate CPZ\u2010induced demyelination by regulating the xCT\/GSH\/GPX4 axis in AS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study utilized forty C57BL\/6 mice, randomly allocated into four groups of ten: a control group, a control group supplemented with PCB2 (60\u2009mg\/kg\/day), a CPZ\u2010exposed group, and a CPZ\u2010exposed group supplemented with PCB2 (60\u2009mg\/kg\/day). The control groups received a standard diet, whereas the CPZ groups were given the same diet supplemented with 0.2% CPZ for 6\u2009weeks. From the fifth week onwards, the control and CPZ groups were administered physiological saline via intraperitoneal injection, whereas the PCB2\u2010supplemented groups received PCB2 for 2\u2009weeks. Immunofluorescence staining, Western blot, and ELISA elucidated the cellular\/molecular mechanisms of PCB2 targeting the xCT\/GSH\/GPX4 axis in AS to alleviate demyelination in\u00a0vivo and in\u00a0vitro.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In this study, PCB2 markedly
