Abstract
In mammalians, social life and circadian rhythms find their neurobiological basis in a network that includes the dopaminergic system. The malfunctioning of dopamine pathways can lead to various disorders such as Attention-Deficit/Hyperactivity and Obsessive/compulsive disorders. A useful research approach is to exploit animal models that carry a functional silencing of SLC6A3 gene, encoding the dopamine transporter (DAT). Hyperactivity, working memory deficits, and asocial tendencies are core features in truncated-DAT rats, for example. We investigated how inheritance and maternal caring style influence circadian rhythms and social behaviours in DAT heterozygous (HET) rats, belonging to four groups: Mat-P, Mat-M, Mix-P, and Mix-M (Mat label stands for care from wild-type dam, Mix label stands for care by heterozygous dam; M label stands for maternal wild-DAT and P label stands for paternal wild-DAT). In Experiment 1, we monitored 24/7 the spontaneous locomotor activity of peri-adolescent subjects. Hyperactivity occurred only in P-asset subjects (with maternal-origin truncated-DAT allele) at specific bins of the day. In Experiment 2, we observed social interactions of the same rats. Mix-M subjects (raised by HET dams and/or inheriting the wild-DAT allele from mothers) tend to interact with all rats; Mat-P (cared by WT dams and/or inheriting the truncated-DAT allele from mothers) seem to be ignored, when acting as stimulus subjects. Overall, results confirm complex modulations for circadian cycle and social life: flexible DAT expression in HET subjects depends on epigenetic combinations of parental inheritance and early experiential factors. Once confirmed, these data could shed light on trans-generational contributions to dopaminergic-related disorders.

Neural networks during delay discounting as trans-disease marker: A meta-analytical review. J Psychiatr Res 2021; 139:62-70. [PMID: 34044265 DOI: 10.1016/j.jpsychires.2021.05.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 04/13/2021] [Accepted: 05/01/2021] [Indexed: 11/30/2022]
Abstract
Delay discounting reflects a devaluation of delayed long-term benefits but pursuing immediate rewards. Higher discounting rates (h-DR) are found ubiquitous in many diseases and unhealthy conditions, particularly in addiction disorder (AD), attention-deficit/hyperactivity disorder (ADHD), and obesity. Thus, h-DR was considered to be a common benchmark across many diseases facilitating to understand one disease to relevant others, which was called trans-disease process. However, the common and specific neural biomarkers associated with this process has not yet been studied well. We performed a voxel-wise task-related neuroimaging meta-analysis to clarify the neural pattern of trans-disease process across AD, ADHD and obesity. We recruited 19 eligible papers, including 9 AD papers (154 patients), 6 ADHD papers (106 patients) and 4 obesity studies (94 patients). Neuroimaging meta-analysis demonstrated the presence of neural biomarkers of trans-disease process: these patients showed inadequate brain response in caudate, ventromedial and dorsolateral prefrontal cortex (dlPFC) than do of healthy controls (HCs). Disease-specific neural patterns were also found, with prominent hypoactivation in parahippocampal-striatum network for AD, hyperactivation in dopamine-projection striatum network for ADHD and decreased activity in dorsal anterior cingulate cortex and dlPFC for obesity. This study provided robust evidence to reveal the neural substrates of trans-disease process, as well further promoted the triple brain network model in favor of the theoretical developments of these neuropsychiatric disorders.
