KCs内质网应激增加了肝组织内M1型KCs数量，降低了肝组织内活化肝星状细胞数量

Endoplasmic reticulum stress KCs increases the number of M1 KCs and reduces the number of activated hepatic stellate cells in the liver. A: Immunohistochemical staining for detection of M1 type KC (×400); B: Number of CD16-positive cells in the liver (^*P < 0.05); C: Detection of the number of active hepatic stellate cells by immunohistochemical staining (×400); D: Number of activated hepatic stellate cells in the liver (^*P < 0.05); E, F: Serum level of TNF-α and its mRNA expression (^*P < 0.05).
