NR3C1 and Anxiety: The fact that some behavioral and biological pathology markers were detected (as increased maternal care and USV together with increased GABA serum levels as well as decrease Morc1 mRNA) but no difference in others was shown (such as Nr3c1 mRNA and glutamate serum levels together with no altered anxiety) might indicate that long term MS exposure induces subclinical depressive changes but by the time of measurement only alters some markers and not all at once.
