Background. Th22 cells are a recently identified CD4+ T helper subset and have been implicated in the pathogenesis of certain diseases in humans, but the role of Th22 cells in liver cirrhosis (LC) remains unclear.
Objectives. The aim of the study was to investigate the expression and clinical significance of intrahepatic Th22 cells in LC tissues.
Material and Methods. Samples of liver tissue of 20 LC patients and 12 normal controls (NC) were collected. Interleukin 22 (IL-22), IL-22R1 mRNA and aryl hydrocarbon receptor (AHR) expression were examined using quantitative reverse transcription polymerase chain reaction (RT-PCR). The protein expression of Th22 and CD4+ cells in liver tissue was measured with immunohistochemistry.
Results. The number of intrahepatic Th22 and CD4+ cells increased markedly in LC patients and the number of Th22 cells positively correlated with the number of CD4+ cells (p < 0.05). Moreover, the number of Th22 cells positively correlated with the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), as well as the Child-Pugh score in LC patients (p < 0.05). The expression of IL-22, IL-22R1 and AHR in LC patients was significantly increased compared with the NC group (p < 0.05).
Conclusion. Our findings suggest that the expression of intrahepatic Th22 cells increased in LC patients and was associated with the progression of LC.
