Objective: We examined the effect of beta-adrenoceptor (AR) blockade in the preclinical phase of experimental autoimmune encephalomyelitis (EAE), the most commonly used model of multiple sclerosis, on the development of primary CD4+ T-cell responses in draining lymph nodes (dLNs). Methods: CD11b+ cell migration to dLNs, CD4+ T-cell activation/proliferation, and IL-17+ CD4+ (Th17) cell numbers in dLN and spinal cord (SC) were examined in male and female Dark Agouti rats using flow cytometry analysis. Results: Irrespective of sex, in propranolol-treated (PT) rats, migration of CD11b+ antigen-presenting cells from the site of immunization to dLNs was impaired compared with saline-treated controls and consequently the frequency of all CD11b+ cells in dLNs and activated cells among them, too. This correlated with decreased expression of CCL19/21 transcripts in dLNs. Consistently, the frequency of activated/proliferating cells among dLN CD4+ T cells was reduced in PT rats. Additionally, prop...ranolol reduced the number of Th17 cells in dLNs and SC. Consistently, male and female PT rats exhibited a decreased incidence of EAE and prolonged duration of the asymptomatic disease phase. Conclusion: This study suggests that sympathetic dysregulation is involved in the outbreak of clinical EAE. (C) 2019 S. Karger AG, Basel
