[Linear and adhesive phenotype of tumor lymphocytes and clinical course of chronic leucosis]

Determination of chronic lymphatic leukemia immunological phenotype, performed by the authors, was based upon the study of quantitative expression of membrane differentiation antigens on peripheral blood lymphocytes. The research included study of co-expression of adhesion molecules, belonging to the following families: beta 2 integrins (CD 11 beta, CD 18), immunoglobulins (CD 50), and CD 38 on tumor blood B-lymphocytes of various CD-types and T-lymphocytes in chronic leucosis. The authors developed a functional model of trans-endothelial migration of peripheral blood lymphocytes in chronic chronic lymphatic leukemia, taking into account their membrane adhesive characteristics and serum level of CD 50. The researchers determined clinical importance of the expression of linear and adhesive antigens on peripheral blood lymphocytes, and soluble HLA-1 (sHLA-1) serum levels in patients with chronic lymphatic leukemia.
