Over the past three decades, the role of vascular inflammation
as amechanismthat participates in the progression of
hypertension has gained increasingly strong footing through
a tremendous amount of supportive reports [11–13]. Khraibi
et al. [14] have found that chronic immunosuppressive therapy
with cyclophosphamide significantly attenuated blood
pressure (BP) elevation inOkamoto spontaneously hypertensive
rats (SHR). This finding supported the hypothesis regarding
the involvement of inflammatory reaction in hypertension.
In the following year, Norman et al. [15] demonstrated
that the development of hypertension was delayed by correcting
the immune imbalance state in SHR. Their works
continued to show that immunological dysfunction is one
of the key aetiologies of hypertension [16]. Dzielak [17]
pointed out an inflammatory involvement in hypertension
by observing an alteration in the serum immunoglobulin
levels in both patients and laboratory animals. Furthermore,
the interaction between inflammatory cells and endothelial
cells was increased in hypertensive patients [18].
