L. reuteri increases oxytocin levels in the PVN of the hypothalamus in Shank3B−/− Rag2−/− mice. (A) Oxytocin immunoreactivity in the PVN of Shank3B−/−-Rag2−/− mice treated with either vehicle or L. reuteri. (B) Oxytocin-positive cell (n = 4 mice per group; Shank3B−/−-Rag2−/− + vehicle versus Shank3B−/−-Rag2−/− +
L. reuteri [unpaired t test, t = 2.519, P = 0.0453]). (C) Oxytocin immunofluorescence intensity (n = 4 mice per group; Shank3B−/−-Rag2−/− + vehicle versus Shank3B−/−-Rag2−/− +
L. reuteri [unpaired t test, t = 3.124, P = 0.0205]). *, P < 0.05. Bar graphs show means ± the SEM with individual data points.
