TNF and familial Mediterranean fever: Specifically, PMNs from the FMF patients displayed higher apoptosis rates compared to the control subjects in response to LPS (45.75 ± 13.8 vs. 15.76 ± 4.12%; p < 0.05), TNFα (50.17 ± 7.41 vs. 18.44 ± 3.81%; p < 0.01, respectively), MDP (29.5 ± 10.21 vs. 10.86 ± 1.29%; p = 0.05), CSK4 (46.77 ± 9.49 vs. 14.61 ± 1.66%; p < 0.01), ATP (24.38 ± 5.04 vs. 7.25 ± 0.85%; p < 0.01), and colchicine (39.62 ± 11.86 vs. 8.22 ± 1.41%; p < 0.05).
