The latest paper of Magda Winiarska PhD. research team in the latest version of Leukemia


On January 10th the latest study have been published in the Leukemia magazine. The study was focused on the effect of B-cell receptor signaling pathway inhibitors on surface CD20 levels and antitumor efficacy of anti-CD20 monoclonal antibodies. For the first time researchers have reported that blocking the activity of BCR signaling pathway using small molecule inhibitors leads to dramatic decrease in surface CD20 levels as assessed in a panel of 16 cell lines and 30 primary B-cell tumor samples. As a consequence, inhibition of BCR signaling pathway leads to substantial decrease in antitumor efficacy of anti-CD20 mAbs. Published results are of great clinical importance and indicate that therapeutic modalities combining BCR inhibitors and anti CD20 mAbs should be introduced consciously and in well planned schemes.

The work was the result of a multicenter collaboration involving scientists from: Depatment of Immunology Medical University of Warsaw, Department of Experimental Hematooncology Medical Univeristy of Lublin, International Centre for Genetic Engineering and Biotechnology Monterotondo (Italy) and IBiSA Cancer Immunomonitoring Platform, Aix-Marseille Université w Marseille (France)
