title: [Circulating mature NK (Leu11+) cells positive for IL2 receptor and HLA-DR in patients with various liver diseases and asymptomatic HBsAg carriers].
abstract: IL2R+ Leu11+ cells (A) and HLADR+ Leu11+ cells (B) of peripheral blood in patients with various liver diseases and ASCs were measured using double colour immunofluorescence assay of MoAb with FACS flow cytometry. 1) The mean % of IL2R+ Leu11+ cells which was 0.5 +/- 0.2 in healthy controls, decreased significantly in HCC in comparison with CALD, ASC and healthy controls, and in ASC rather than in healthy controls. They (A) were less than 0.1% in eight of thirteen cases with HCC, in one of twenty cases with CALD and of eleven ASCs, respectively. 2) In the mean % of HLADR+ Leu11+ cells which was 2.9 +/- 1.8 in healthy controls there was not a significant difference among HCC, CALD, ASC, AH and healthy controls. They (B) were less than 0.1% only in one case with HCC. 3) The value of fluorescence intensity of IL2R on IL2R+ Leu11+ cells reduced in B-CALD, ASC, AH and HCC, and one of HLADR on HLADR+ Leu11+ cells increased in CALD. These results suggested that the decrease of IL2R+ Leu11+ cells was due to the existence of HCC.
