From: Evidence for long-term sensitization of the bowel in patients with post-infectious-IBS

No evidence for low-grade inflammation in rectal biopsy samples of PI-IBS patients. (A) Relative mRNA expression for inflammatory markers normalized to β-actin in rectal biopsies of HV (n = 9) and PI-IBS (n = 8) patients. (B) Counting of plasma cells, B cells, CD3+ T cells, eosinophils, IgE+ cells and mast cells, in HV (n = 9) and PI-IBS (n = 8) rectal biopsies (as indicated). Mann-Whitney U test, *p < 0.05; **p < 0.01. HV = healthy volunteer, IFN = interferon, IL = interleukin, MCP-1 = monocyte chemoattractant protein-1, PI-IBS = post-infectious IBS, TNF = tumor-necrosis factor.
