Nyati and colleagues1 described a cohort of 65 patients with Guillain-Barré syndrome (GBS) with characteristic lymphocyte cytokine expression profiles in response to Campylobacter jejuni outer membrane protein stimulation. While their findings followed the T helper (Th) 1/Th2 paradigm, they should be interpreted with caution before robust conclusions are drawn.
