Effects of CD4⁺CD25⁺ Treg cells deficiency on levels of serotonin (5-HT) (A) and its metabolite, 5-HIAA, (B) within the hippocampus (n = 5–8).

Abstract

<p>After the behavioral tests, the prefrontal cortex and hippocampus were dissected from the mice and homogenized. Each supernatant sample was injected into a reversed phase HPLC column. The amounts of monoamines and metabolites were then determined using an electrochemical detector. Data were analyzed using separate one-way ANOVA followed by a <i>post hoc</i> Newman-Keuls test. * <i>p</i><0.05 <i>vs.</i> the non-stressed control group. Vertical bars indicate the S.E.</p
