Altered pattern of tumor necrosis factor-alpha production in peripheral blood monocytes from Crohn's disease

Figure 1 Intracellular tumor necrosis factor-alpha expression in peripheral monocytes. Intracellular TNF-α expression in peripheral monocytes derived from patients affected by Crohn’s disease (CD), ulcerative colitis (UC) and healthy donors (HD), in basal condition (A), or after stimulation with Pam₃CSK₄ (B), MDP-L18 (C), LPS (D) or Poly I:C (E). Data are presented as mean ± SEM. Statistical significance is denoted by letters (^aP < 0.05, ^bP < 0.01, ^cP < 0.001 vs HD).
