Biological and Immunological Characterization of a Human Liver Immunoregulatory Protein
Gabriele E. Schrempf‐Decker, Diethard P. Baron, Norbert W. Brattig, Hermann Bockhorn, Peter A. Berg – 1 January 1983 – The liver immunoregulatory protein (LIP) was originally characterized as human liver‐derived soluble factor which inhibited the alloantigen and phytohemagglutinin‐induced proliferation of human lymphocytes (1). Soluble extracts prepared under the same experimental conditions from kidney, spleen, heart, lymph nodes, and erythrocytes did not exert any inhibitory activity (2). The purpose of this study was to characterize the immunobiological properties of LIP.
