TNF and neuroblastoma: As for the innate immune responses, no significant differences in the Borrelia induced cytokine IL-1β, IL-6, IL-10, or TNF secretion between groups were found in our study, whereas in a previous study by Sjöwall et al. [21], an increased number of Borrelia-induced TNF-secreting DCs were found in asymptomatic adults as compared to patients with a history of NB [21].
