OVA-induced intestinal mast cell degranulation is impaired in
TSLPR-deficient mice. (A) Frequency of lineage negative
cKit+IgE+ mast cells isolated from small intestine;
IgE presence on surface of mast cells was determined by MFI. (B)
MCPT1 blood levels 2 hours after intragastric OVA challenge. Significance was
assessed by 1-way ANOVA (*P < .05, **P
< .01, ***P < .001, ****P
< .0001, ns = not significant). MFI,
Mean fluorescent intensity.
