Fig. 7. Upregulation of neuronal IL-13 is driven by neuronal activity and nuclear calcium signaling upon traumatic brain injury.

a, b Upregulation of IL-13 mRNA expression upon blunt, closed TBI in mouse (3 h post injury). Chemogenetic suppression of inhibitory PV interneurons enhances the upregulation of IL-13 mRNA at baseline and after trauma (Saline Sham vs Saline TBI: p < 0.0001; Saline Sham vs PSEM Sham: p = 0.0150; Saline TBI vs PSEM TBI: p = 0.0742). N = 3; n = SS: 332; ST: 422; PS: 382; PT: 319 neurons. c, d Neuronal nuclear calcium buffering (PV.NLS) strongly reduces IL-13 mRNA at baseline and upon TBI (Control Sham vs Control TBI: p = 0.0141; Control Sham vs PV.NLS Sham: p = 0.00141; Control TBI vs PV.NLS TBI: p = 0.0069). N = 3; n = MS: 427; MT: 394; PS: 215; PT: 385 neurons. Scale bar: 20 μm. *: p < 0.05; **: p < 0.01; ****: p < 0.0001. b, d One-way ANOVA with Sidak’s multiple comparison.
