Dataset Summary
TitleMeningeal γδ T cells producing IL-17 control synaptic plasticity and cognitive behaviour
DescriptionThe conventional notion of “immune privilege” of the brain has been revised to accommodate its infiltration, at steady state, by immune cells that participate in normal neurophysiology (Louveau, Trends Immunol 2015; Kipnis science 2016; Filiano, Nat Rev Neurosciences 2017). Surprisingly, such neuroimmune functions have been linked to “pro-inflammatory” cytokines like IL-4 or IFN-α, shown to control behavioural and social cognition (Derecki, JEM 2010; Filiano, Nature 2016). Here we identify a pro-cognitive role for IL-17 in short-term memory that derives from a previously unknown meningeal-resident γδ T cell subset. This was mostly composed of foetal thymic-derived Vγ6+ T cells, found in the meninges at birth and persisting throughout life, where they were strikingly polarized towards IL-17 production. In fact, γδ T cells were the overwhelming source of meningeal IL-17, whereas IFN-γ was mostly provided by T cells. To assess whether the constitutive production of IL-17 by γδ T cells influenced the cognitive performance of mice, we tested TCRδ-/-, IL-17-/- and respective WT littermate control mice in classical learning paradigms. We observed that mice deficient either for γδ T cells or IL-17 displayed impaired short-term memory in the Y maze paradigm, while retaining normal long-term spatial memory in the Morris water maze. A detailed proteomics analysis of the hippocampus provided mechanistic insight into reduced plasticity of the glutamatergic synapses in the absence of IL-17, which associated with impaired Long Term Potentiation (LTP). Conversely, IL-17 enhanced glial cell production of Brain Derived Neurotropic Factor (BDNF), whose exogenous provision rescued the LTP defect of IL-17-/- animals. Altogether, our data demonstrate that foetal-derived γδ T cells populate the brain meninges where they regulate synaptic plasticity and short-term memory through a non-inflammatory IL-17-dependent mechanism.
