In our study, some inflammatory Interleukin-2 , Interleukin-6, Interferon-γ, Tumor Necrosis Factor-α and anti-inflammatory Interleukin-4 and Interleukin-10 cytokine genes expressions and Triggering Receptor Expressed On Myeloid Cells- 1, which contributes to the pathology of acute and chronic inflammatory diseases; Human Leukocyte Antigen-G5, which suppresses the immune response; the expression levels of transcription factor Forkhead box-P3 expressed in regulatory T-lymphocytes and Cluster of Differentiation (CD)14 genes, which are thought to be biomarkers in various infectious diseases and expressed in monocytes, will be measured from peripheral blood samples obtained from liver transplant patients before, 1 month and 6 months after the operation. In addition, the classical liver markers Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Platelet Count (PLT), Alpha Feto Protein (AFP), Direct Bilirubin (Bilirubin D), Total Bilirubin (Bilirubin T) and C- Levels of biochemical parameters such as Reactive Protein (CRP) will be measured. In the light of the data to be obtained, it is aimed to find biomarkers with high predictive value for rejection and infection after liver transplantation.

Liver transplantation is the transplantation of the liver, which is completely or partially removed by surgical intervention, from a living or brain-dead cadaver to the recipient. Today, organ transplantation procedures are carried out successfully in many centers in our country.Liver transplantation has become the most effective treatment method for acute and chronic liver failure due to different reasons.The life expectancy of individuals with advanced liver disease, which was limited to months before liver transplantation, was extended with liver transplantation and the quality of life was improved with this treatment method. However, since most of the organ transplants are made from genetically different donors, tissue compatibility between the donor and the recipient remains a problem.Therefore, the recipient's immune response to donor graft antigens should be considered.

In recent years, the application of advanced surgery and new immunosuppressive approaches has made it possible to successfully transplant almost any vital organ or tissue. However, due to both infection and genetic factors, an immune response to the donor organ may develop and cause organ rejection. At this point, we think that early diagnosis and discovery of immune response parameters that distinguish infection from rejection may be important.In our study, some inflammatory Interleukin-2 , Interleukin-6, Interferon-γ, Tumor Necrosis Factor-α and anti-inflammatory Interleukin-4 and Interleukin-10 cytokine genes expressions and Triggering Receptor Expressed on Myeloid Cells-1, which contributes to the pathology of acute and chronic inflammatory diseases; Human Leukocyte Antigen-G5, which suppresses the immune response; the expression levels of transcription factor Forkhead box-P3 expressed in regulatory T-lymphocytes and Cluster of Differentiation (CD)14 genes, which are thought to be biomarkers in various infectious diseases and expressed in monocytes, will be measured from peripheral blood samples obtained from liver transplant patients before, 1 month and 6 months after the operation. In addition, the classical liver markers Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Platelet Count (PLT), Alpha Feto Protein (AFP), Direct Bilirubin (Bilirubin D), Total Bilirubin (Bilirubin T) and C- Levels of biochemical parameters such as Reactive Protein (CRP) will be measured. In the light of the data to be obtained, it is aimed to find biomarkers with high predictive value for rejection and infection after liver transplantation.
