Fig 5. Serum concentrations of the pro-inflammatory cytokine MCP-1 declined during the study course.

Analysis of MCP-1 serum levels was performed at the beginning of the bilberry intake (week 1) and subsequently in intervals of 2 weeks (week 3, week 5 and week 7). Red dots are derived from patients that reached remission (n = 7) at the end of the study whereas black dots belong to patients that did not reach remission (n = 3). Overall, a decline in MCP-1 serum levels at the end of the study was registered only in patients reaching remission.
