Existing is Ordinary: resistance maps in the curricula and teaching

ABSTRACT: Faced nowadays with the words teaching, curriculum and school, the verb to resist sounds like an inescapable premise to the possibilities of fairer, more solidary and democratic social forms. Based on results from researches on the production of curricula and teachers training, we seek, through teacher narratives, to map resistance movements of the public and the common in everyday practices. We argue that forms of resistance do not necessarily arise as responses to hegemonic logics and to agendas that reduce life to economic interests. To resist, in the dialogue that we establish with authors from the field of philosophy, of the new epistemologies and of the studies of everyday life, implies in the ordinary and everyday production of the forms of existence.</p

Background and ObjectivesInhibition of de novo pyrimidine synthesis in proliferating T and B lymphocytes by teriflunomide, a pharmacological inhibitor of dihydroorotate dehydrogenase (DHODH), has been shown to be an effective therapy to treat patients with MS in placebo-controlled phase 3 trials. Nevertheless, the underlying mechanism contributing to the efficacy of DHODH inhibition has been only partially elucidated. Here, we aimed to determine the impact of teriflunomide on the immune compartment in a longitudinal high-dimensional follow-up of patients with relapse-remitting MS (RRMS) treated with teriflunomide.MethodsHigh-dimensional spectral flow cytometry was used to analyze the phenotype and the function of innate and adaptive immune system of patients with RRMS before and 12 months after teriflunomide treatment. In addition, we assessed the impact of teriflunomide on the migration of memory CD8 T cells in patients with RRMS, and we defined patient immune metabolic profiles.ResultsWe found that 12 months of treatment with teriflunomide in patients with RRMS does not affect the B cell or CD4 T cell compartments, including regulatory TREG follicular helper TFH cell and helper TH cell subsets. In contrast, we observed a specific impact of teriflunomide on the CD8 T cell compartment, which was characterized by decreased homeostatic proliferation and reduced production of TNFα and IFNγ. Furthermore, we showed that DHODH inhibition also had a negative impact on the migratory velocity of memory CD8 T cells in patients with RRMS. Finally, we showed that the susceptibility of memory CD8 T cells to DHODH inhibition was not related to impaired metabolism.DiscussionOverall, these findings demonstrate that the clinical efficacy of teriflunomide results partially in the specific susceptibility of memory CD8 T cells to DHODH inhibition in patients with RRMS and strengthens active roles for these T cells in the pathophysiological process of MS.</p
