#Meningeal γδ T cells regulate #anxiety-like behavior via IL-17a signaling in neurons

Interleukin (IL)-17a has been highly conserved during evolution of the vertebrate immune system and widely studied in contexts of infection and autoimmunity. Studies suggest that IL-17a promotes behavioral changes in experimental models of autism and aggregation behavior in worms. Here, through a cellular and molecular characterization of meningeal γδ17 T cells, we defined the nearest central nervous system–associated source of IL-17a under homeostasis. Meningeal γδ … Continue reading #Meningeal γδ T cells regulate #anxiety-like behavior via IL-17a signaling in neurons

#Sleep duration and affective reactivity to #stressors and positive events in daily life

Objective: Experimental evidence suggests that inadequate sleep disrupts next-day affective processing and evokes greater stress reactivity. However, less research has focused on whether sleep predicts next-day affective reactivity to naturally occurring stressors and positive events in daily life, as well as the reversed direction of association (i.e., affective reactivity to daily events as predictors of subsequent sleep). The purpose of this study was to evaluate … Continue reading #Sleep duration and affective reactivity to #stressors and positive events in daily life
