CAV1 and hypertensive disorder: In this study, we confirmed that caveolin-1 is expressed at significantly higher relative levels in neutrophils from patients with hypertension (HTN) compared to neutrophils from normotensive individuals (NTI) (1.22 ± 0.071 vs. 1.05 ± 0.068; p = 0.0391) with the band detected at ∼24 kDa (Figure 2A).
