Fig. 1: AIM2 levels were measured in CSF from patients.

a Western blot assay for the AIM2 protein in CSF samples from control and SAH patients; b Western blot assay for the AIM2 protein in CSF samples from SAH patients with different Hunt-Hess grade (Control, n = 10; SAH, n = 24; Hunt-Hess grade I–II, n = 15; III–V, n = 9). Samples were run on the same gel but were noncontiguous. Data are presented as the mean ± S.E.M. ****P < 0.0001. AIM2, absent in melanoma 2; CSF cerebrospinal fluid; CTL control; SAH subarachnoid haemorrhage.
