To investigate stroke‐induced changes in pan‐lactylation across different brain cell types, we performed immunofluorescence co‐staining of pan‐Kla with markers of neurons (MAP2 or NeuN), astrocytes (GFAP or S100β), microglia (IBA1), and oligodendrocytes (Olig2 or MBP). The gene discussed is MBP; the disease is Stroke.
