To examine the non-immunological effects of RTX on PAN induced cytoskeletal defects, podocytes were grown under growth restrictive conditions for 12 days and subsequently incubated with media containing 10% FBS in the presence of 30 µg/ml PAN (Sigma, Munich, Germany), 100 µg/ml MabThera (Roche, Basel, Switzerland) or the combination of both for 48 h. All experiments were performed at least three times starting on growth-restricted days 12–14 (methodology previously described in13 (link)).
