More than 60% of the treated Lyme neuroborreliosis patients reported one or more symptoms in the Lyme-specific questionnaire (Table 1); however, no correlation was found between these self-reported symptoms and the number of B. burgdorferi B31-specific IFN-γ-secreting T cells/2.5 × 105 PBMCs (rs, 0.200; P = 0.235). The gene discussed is IFNG; the disease is Lyme disease.
