To further investigate the role of P4HB and ERp57 in B. cenocepacia interaction with 9HTEo-cells, we have carried out infection experiments in presence of 50 μg/ml of a function-blocking anti-P4HB antibody30 or of an anti-ERp57 antibody, after pre-treating the cells for 30 minutes with the antibodies. The gene discussed is PDIA3; the disease is infection.
