We investigated the role of interleukin 2 receptor expression (IL 2R) on T cell in chronic liver disease. IL 2R was determined by analysing T cell surface Tac antigen with anti-Tac, a monoclonal antibody that binds at or near the binding site for IL 2, using a fluorescence-activated cell sorter. The percentage of Tac+ cells in T cell fraction from peripheral blood mononuclear cells in unstimulated cultures was 7.9 +/- 2.1% (+/- SD) in controls. A similar value was obtained in asymptomatic carriers of HBsAg (ASC), in patients with chronic active hepatitis (CAH) and liver cirrhosis (LC). Upon stimulatin with recombinant IL 2, there was a small but significant increase in Tac+ cells. The percentages of Tac+ cells in IL 2-stimulated cultures were significantly lower in ASC (P less than 0.01), patients with CAH (P less than 0.01) and LC (P less than 0.05) as compared to controls (16.4 +/- 4.4%). Percentages of Tac+ cells after stimulation with phytohemagglutinin P (PHA-P) in ASC and CAH did not differ from controls (74.9 +/- 5.9%). Only patients with LC showed diminished Tac+ cells (P less than 0.01) compared to controls. During a 4-wk course of recombinant IL 2 therapy, a serial study on 5 HBeAg-positive patients with CAH was done, and the results showed that Tac+ cells were significantly diminished 2 wk (P less than 0.01) and 4 wk (P less than 0.05) after starting therapy in comparison with pretreatment levels in IL 2-stimulated cultures.(ABSTRACT TRUNCATED AT 250 WORDS)

D008103	Liver Cirrhosis	Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules.

D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D006509	Hepatitis B	INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.	Hepatitis B Virus Infection
D006521	Hepatitis, Chronic	INFLAMMATION of the LIVER with ongoing hepatocellular injury for 6 months or more, characterized by NECROSIS of HEPATOCYTES and inflammatory cell (LEUKOCYTES) infiltration. Chronic hepatitis can be caused by viruses, medications, autoimmune diseases, and other unknown factors.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D015375	Receptors, Interleukin-2	Receptors present on activated T-LYMPHOCYTES and B-LYMPHOCYTES that are specific for INTERLEUKIN-2 and play an important role in LYMPHOCYTE ACTIVATION. They are heterotrimeric proteins consisting of the INTERLEUKIN-2 RECEPTOR ALPHA SUBUNIT, the INTERLEUKIN-2 RECEPTOR BETA SUBUNIT, and the INTERLEUKIN RECEPTOR COMMON GAMMA-CHAIN.
