Peripheral organs, especially the kidney, and liver, may be affected by the onset of molecular responses following brain tissue damage. While secondary injury responses post TBI has been well studied in the brain, the effect/consequences of these responses in the peripheral organs have not yet been fully elucidated.

Animal behaviour capacities and neuronal damage were assessed via behavioural tests, tyrosine hydroxylase (TH) staining, and immunofluorescence. Levels of HSF1, miR-214-3p, nuclear factor of activated T cells 2 (NFATc2), and neuroinflammatory factors were detected via RT-qPCR, Western blotting, and ELISA.Binding relationships between HSF1 and miR-214-3p, miR-214-3p, and NFATc2 were tested via dual-luciferase or chromatin immunoprecipitation assays. Functional rescue experiments were designed to confirm the roles of miR-214-3p and NFATc2. HSF1 expression in brain tissues was downregulated upon MPTP treatment. HSF1 overexpression reduced motor deficits and loss of dopaminergic neurons, increased TH-positive neurons, and repressed neuroinflammation and micro-glia activation. Mechanically, HSF1 bound to the miR-214-3p promoter to increase its expression and inhibited NFATc2 transcription. miR-214-3p downregulation or NFATc2 overexpression reversed the inhibition of HSF1 overexpression on neuroinflammation and microglia activation.
