PV and SST neurons in the anterior cingulate cortex regulate social disorders in adulthood induced by sensory abnormalities in childhood.

ABSTRACT:

Objective

Childhood sensory abnormalities experience has a crucial influence on the structure and function of the adult brain. The underlying mechanism of neurological function induced by childhood sensory abnormalities experience is still unclear. Our study was to investigate whether the GABAergic neurons in the anterior cingulate cortex (ACC) regulate social disorders caused by childhood sensory abnormalities experience.

Methods

We used two mouse models, complete Freund's adjuvant (CFA) injection mice and bilateral whisker trimming (BWT) mice in childhood. We applied immunofluorescence, chemogenetic and optogenetic to study the mechanism of parvalbumin (PV) neurons and somatostatin (SST) neurons in ACC in regulating social disorders induced by sensory abnormalities in childhood.

Results

Inflammatory pain in childhood leads to social preference disorders, while BWT in childhood leads to social novelty disorders in adult mice. Inflammatory pain and BWT in childhood caused an increase in the number of PV and SST neurons, respectively, in adult mice ACC. Inhibiting PV neurons in ACC improved social preference disorders in adult mice that experienced inflammatory pain during childhood. Inhibiting SST neurons in ACC improved social novelty disorders in adult mice that experienced BWT in childhood.

Conclusions

Our study reveals that PV and SST neurons of the ACC may play a critical role in regulating social disorders induced by sensory abnormalities in childhood.

Project description:ObjectiveThe anterior cingulate cortex (ACC) is critical for both stress and inhibitory control processes and has been implicated in childhood trauma. This prospective study tested the hypothesis that early trauma moderates the association between inhibitory control during late childhood and ACC stress reactivity during adolescence.MethodSixty-four adolescents were stratified into higher- or lower-childhood-trauma groups. Inhibitory control was indicated by fewer errors on a Stroop Color-Word task. Personalized stress cues during functional magnetic resonance imaging assessed neural correlates of stress in adolescents.ResultsUsing a priori-defined anterior (rCZa) and posterior rostral cingulate zones of the ACC, associated with Stroop Color-Word task performance in prior meta-analyses, Stroop errors correlated inversely with activation in the rCZa during stress-cue exposure (r = -.23, p = .04). Childhood trauma moderated the association between Stroop errors and rCZa stress reactivity (interaction = -1.26, p = .02, 95%CI = -2.33,-0.20), where Stroop errors were inversely associated with brain activation among those with higher childhood trauma (simple slopes = -.83, p = .007, 95%CI = -1.40,-0.25). Low stress-related rCZa activation inversely (R2 = 0.19, b = -0.43, p = .001, 95%CI = -4.11,-1.06) and Stroop errors directly (R2 = 0.09, b = 0.27, p = .048, 95%CI = 0.02, 5.8) associated with baseline subjective anxiety while controlling for childhood trauma.ConclusionsThis is the first study to demonstrate a moderating role of childhood trauma on the relationship between inhibitory control and stress-related ACC activation. Childhood trauma may portend neurodevelopmental changes that impede recruitment of control-associated ACC-functioning during distress, which may relate to dysregulation of stress-induced affective responses. Further work is needed to elucidate relationships between childhood trauma and addictive behaviors precipitated by stress.

Project description:The subgenual anterior cingulate cortex (sgACC) is a key node of the descending antinociceptive system with sex differences in its functional connectivity (FC). We previously reported that, in a male-prevalent chronic pain condition, sgACC FC is abnormal in women but not in men. This raises the possibility that, within a sex, sgACC FC may be either protective or represent a vulnerability to develop a sex-dominant chronic pain condition. The aim of this study was to characterize sgACC FC in a female-dominant chronic pain condition, carpal tunnel syndrome (CTS), to investigate whether sgACC abnormalities are a common feature in women with chronic pain or unique to individuals with pain conditions that are more prevalent in the opposite sex. We used fMRI to determine the resting state FC of the sgACC in healthy controls (HCs, n = 25, 18 women; 7 men) and people with CTS before (n = 25, 18 women; 7 men) and after (n = 17, 13 women; 4 men) successful surgical treatment. We found reduced sgACC FC with the medial pre-frontal cortex (mPFC) and temporal lobe in CTS compared with HCs. The group-level sgACC-mPFC FC abnormality was driven by men with CTS, while women with CTS did not have sgACC FC abnormalities compared with healthy women. We also found that age and sex influenced sgACC FC in both CTS and HCs, with women showing greater FC with bilateral frontal poles and men showing greater FC with the parietal operculum. After surgery, there was reduced sgACC FC with the orbitofrontal cortex, striatum, and premotor areas and increased FC with the posterior insula and precuneus compared with pre-op scans. Abnormally reduced sgACC-mPFC FC in men but not women with a female-prevalent chronic pain condition suggests pain-related sgACC abnormalities may not be specific to women but rather to individuals who develop chronic pain conditions that are more dominant in the opposite sex. Our data suggest the sgACC plays a role in chronic pain in a sex-specific manner, and its communication with other regions of the dynamic pain connectome undergoes plasticity following pain-relieving treatment, supporting it as a potential therapeutic target for neuromodulation in chronic pain.
