We also performed immunostaining using the TREK-1 antibody in brain sections after traumatic intracranial hypertension (Figure 3(a)), and the results showed that RDC and CDC both increased the expression of TREK-1 with the higher levels of TREK-1 in the CDC group (Figure 4(b)). The gene discussed is KCNK2; the disease is intracranial hypertension.
