Stimulation of 5HT3 receptors in the NTS increases arterial pressure independently of GABA(A) receptors and baroreflex sensitivity, with an exaggerated response in spontaneously hypertensive rats.

May implicate NTS 5HT3 receptors in hypertensive pressor responses; hypothesis-generating in animals and should not change practice.
Tsukamoto et al. (2000) studied this question.
