Standard therapy of patients with B cell non-Hodgkin lymphoma (B-NHL) predominantly consists of chemotherapy combined with anti-CD20 (e.g., rituximab) immunotherapy. However, relapse of aggressive B-NHL occurs frequently, and this may coincide with therapy resistance. This demonstrates the urgent need for exploring new lymphoma-targeted therapies. We review here recent insights in the pathophysiology of B-NHL and discuss CD20 and three alternative membrane targets (B cell receptor, immune checkpoints PD-1/PD-L1, tetraspanin CD37) that are currently in the spotlight for B-NHL treatment. Furthermore, we present a novel concept in which the plasma membrane organization of the lymphoma B cell determines the efficacy of membrane-targeted therapies, and this has consequences for treatment application and clinical outcome in patients with B cell lymphoma.
