title: [Interleukin-1-like factor from human B-lymphocytes transformed by the Epstein-Barr virus].
abstract: The NC-37, EBV-transformed human B-lymphoblastoid cell line spontaneously produces interleukin (IL)-1-like factor, which is able to stimulate proliferation of mouse thymocytes and human fibroblasts. The IL-1-like factor production can be enhanced by prodigiozan and by the conditioned medium of human peripheral blood mononuclear cells. The NC-37 cells have a membrane-associated form of IL-1-like factor also. The molecular mass of the intracellular precursor of this factor determined by gel-filtration is 35-40 kDa, and that of the secretory form--18-20 kDa. The secretory form has the following isoelectric points: 4.5; 6.8; 7.2-8.4.
