Non-T(H)1 cytokines are augmented systematically early in Guillain-Barré syndrome

Abstract

The T(H)1 vs non-T(H)1 cytokine balance in Guillain-Barré syndrome (GBS) is unknown. Using enzyme-linked immunospot (ELISPOT) assays, we observed elevated numbers of interleukin (IL)-6 and IL-10-secreting blood mononuclear cells (BMNC) during the acute phase in untreated patients, and low levels of tumor necrosis factor alpha-secreting BMNC in the recovery phase of GBS. Numbers of IL-12p70-secreting BMNC were not affected over the course of GBS. The non-T(H)1 cytokine profile observed early in GBS may explain the self-limited clinical course associated with GBS.
