FIG 4.

Role of the 5-HT₃ receptor in intestinal secretion induced by rotavirus infection. Potential difference (PD) was measured in jejunal segments (4 mice per group) from wild-type and 5-HT₃ receptor KO pups at 48 hpi. PD was measured every 30 min over 2 h in Ussing chambers. There was no significant difference between infected wild-type and 5-HT₃ receptor KO mice. This suggests that the 5-HT₃ receptor does not play a major role in rotavirus-induced electrolyte secretion. mV, millivolt. Data are expressed as mean with SEM. Two-way ANOVA test.
