Abstract:
To investigate the expression of serine metabolism related genes and inflammatory relat-ed genes in CD4+T cells of healthy and cows with ketosis.Firstly,CD4+T cells in peripheral blood of dairy cows were isolated by magnetic bead sorting.Second,expression of serine metabolism re-lated genes PHGDH,PAST1,PSPH,SHMT1,SHMT2,SDS,SFXN1 and inflammation related genes IL-6,IFN-γ,IL-17A,FOXP3,IL-10,TGF-β in CD4+T cells in healthy and ketosis cows was detected by fluorescence quantitative PCR.The transcription levels of PHGDH,PAST1 and PSPH in CD4+T cells of ketosis cows were significantly increased compared with healthy cows(P<0.01),the transcription level and translation level of SDS were significantly increased(P<0.01).The transcription levels of SHMT2 were significantly decreased(P<0.05).Transcription and translation levels of SFXN1 were significantly decreased(P<0.05).The transcription level of SHMT1 was decreased but not significantly.Compared with healthy cows,the transcription levels of IL-6,IFN-γ and IL-17A in CD4+T cells of ketosis cows were significantly increased(P<0.01),the transcription levels of IL-10,TGF-β and FOXP3 were significantly decreased(P<0.05).The results showed that the expression of genes related to serine synthesis increased,the expression of genes related to serine decomposition decreased,the expression of pro-inflammatory factors increased,and the expression of anti-inflammatory factors decreased,suggesting that serine metab-olism plays an important role in the inflammatory process of dairy cows.
