Figure 1. Rate of neutrophil survival and apoptosis.

Figure 1

Neutrophils isolated from 60 HBD, 44 AASV patients, 8 PV patients, 18 TP, 21 SLE patients, and 20 RA patients were cultured in vitro in AIM-V medium. The percentage of surviving neutrophils (1a) and apoptotic neutrophils (1b) was measured after 20 hours. % Neutrophil survival = % of annexin-V negative and 7-AAD negative cells after 20 hour culture. % Neutrophil apoptosis = % of annexin-V positive and 7-AAD negative cells after 2o hour culture. HBD = healthy blood donors. AASV = ANCA-Associated Systemic Vasculitis. PV = Polycythemia Vera. TP = renal transplant recipients. SLE = Systemic Lupus Erythematosus. RA = Rheumatoid Arthritis.
