| Research Abstract |
Previously, we published a manuscript entitled "Impairment of IFN-α production capacity in patients with hepatitis C virus and the risk of the development of hepatocellular carcinoma" in World J Gastroenterology, which forms the basis of this project. The project entailed the establishment of a database of IFN-α production and blood tests spanning 17 years by the Louis Pasteur Center for Medical Research. Data for IFN-α production was obtained retrospectively over a 17-year period by examining medical records in a study population of 2,315 individuals, of which 112 healthy controls and 20 HCV-infected patients were selected. Sixty percent of the HCV-infected patients had impaired or declining IFN-α production in comparison to 17% in the healthy control group. Mean IFN-α levels were lower in patients who developed hepatocellular carcinoma than in the HCV-infected patients who remained cancer-free. These results have been published in J IFN ＆ Cytokine Research as "Impaired interferon-a production and the risk of cancer development." Further, we established the methodto detect IFN-α producing cells by Sendai virus stimulation using FACS, and the main IFN-α producing cells were plasmacytoid dendritic cells. This method will be useful to understand the analysis of impaired IFN-α production.
