Increased IL-17A levels in mothers transfected with
pCpG-MuIl17a resulted in elevated levels of
kynurenine (KYN) in the dams and fetus. (a) Relative
IL-17Ra and IL-17Rc mRNA levels in
embryonic day 14.5 (E14.5) fetal brains derived from pCpG-mcs- or
pCpG-MuIl17a gene-transfected mothers at E12.5
(N = 4-5 mice per group, 2 independent experiments). Serum (b) and
placenta (c) concentrations of tryptophan (TRP) metabolites in E18.5
dams (N = 7-11 mice per group, 3 independent experiments) after pCpG-mcs
or pCpG-MuIl17a gene transfection into pregnant dams on
E12.5. (d) Concentrations of TRP metabolites in fetal plasma at E18.5
(N = 3-5 pooled plasma per group). (e) Schematic presentation of E18.5
fetal brain structure. Hipp, hippocampus; LGE, lateral ganglionic
eminence; MGE, medial ganglionic eminence; POa, preoptic area; St,
striatum. (f and g) Concentrations of TRP metabolites were measured in
fetal brain regions of subpallium (f) and pallium (g) (N = 6-9 fetus per
group, 2 independent experiments). Data are presented as
means ± standard error of the mean (SEM). Student’s
t-test, *P < .05,
**P < .01, ***P < .001,
****P < .0001, vs control mice.
