Clinical Study

In Crohn's Disease, Anti-TNF- 𝜶 Treatment Changes the Balance between Mucosal IL-17, FOXP3, and CD4 Cells

Table 2

mRNA expression of L-17, IL-23, FOXP3, IFN- 𝛾 and TNF- 𝛼 in ileal and colonic biopsy samples taken before (0) and 3 months after the beginning of anti-TNF- 𝛼 treatment. Median (range) mRNA levels are expressed as relative units in relation to in-house calibrator (phytohemagglutinin-stimulated peripheral blood monocytes). Asterix: statistically significant differences between patients and control subjects.
