The Role of B-cell Receptor Signaling in Lymphoid Malignancies
Kochmannová, Kateřina ; Havránek, Ondřej (advisor) ; Štěpánek, Ondřej (referee)
The aim of this thesis is to review current knowledge about tumor-specific B cell receptor (BCR) signaling and related novel therapy options in B-cell malignancies with the main focus on non-Hodgkin lymphomas (NHL). To a certain degree, the pathogenic BCR signaling mirrors normal forms of BCR signaling, antigen-induced and tonic. Differences between antigen- dependent and antigen-independent forms of BCR signaling are well characterized in two major subtypes of diffuse large B-cell lymphoma, the most common type of NHL. In addition to the conventional chemotherapy, several BCR inhibitors targeting BTK and PI3K have been approved for the treatment of lymphoid malignancies. However, improvements in the tumor specificity, toxicity profiles and patients selection are needed. A better understanding of BCR signaling deregulation and overall tumor pathogenesis is believed to further improve NHL treatment outcomes.
