Moreover, to determine which cell types express IL-33 and ST2 in a rat model of noncompressive lumbar disk herniation, double staining was performed using anti-IL-33 or anti-ST2 antibodies and antibodies specific for neurons (NeuN), astrocytes (GFAP), microglia (OX-42), or oligodendrocytes (Olig-2). The gene discussed is RBFOX3; the disease is lumbar disc herniation.
