Abstract Psychosocial stress has profound effects on the body, including immune system and brain 1,2 . Although a large number of pre-clinical clinical studies have linked peripheral alterations to stress-related disorders such as major depressive disorder (MDD) 3 , underlying mechanisms are not well understood. Here we show that expression circulating myeloid cell-specific proteinase, matrix metalloproteinase 8 (MMP8), is increased in serum humans with MDD stress-susceptible mice following chronic social defeat (CSDS). In mice, this increase leads extracellular space neurophysiological changes nucleus accumbens (NAc), altered behaviour. Using combination mass cytometry single-cell RNA sequencing, performed high-dimensional phenotyping cells circulation demonstrate monocytes strongly affected by stress. both traffic showed Mmp8 We further MMP8 directly infiltrates NAc parenchyma controls ultrastructure space.

The lateral septum (LS) is a midline, subcortical structure that critical regulator of social behaviors. Mouse studies have identified molecularly distinct neuronal populations within the LS, which control specific facets behavior. Despite its known molecular heterogeneity in mouse and role regulating behavior, comprehensive profiling human LS has not been performed. Here, we conducted single-nucleus RNA sequencing (snRNA-seq) to generate transcriptomic profiles compared recently collected snRNA-seq datasets. Our analyses TRPC4 as conserved marker while FREM2 enriched only LS. We also identify cell type marked by OPRM1, gene encoding μ-opioid receptor. Together, these results highlight transcriptional robust genes for

Background Social motivation is posited as a key factor in the expression of autism phenotype. However, lack precision both conceptualization and measurement has impeded thorough understanding its diverse presentation associated outcomes. This study addresses this gap by identifying subgroups characterized deficits distinct facets social motivation, relative to normative benchmarks. Methods Data were from 509 participants with autism, aged 5‐to‐21 years ( M = 10.43, SD 3.67; 81% male), enrolled Healthy Brain Network. Latent profile analysis was employed identify unique configurations reticence, seeking, maintaining derived comprehensive multi‐instrument symptom screening measures. Pearson's chi‐square tests one‐way variance performed explore subgroup differences demographic characteristics, cognitive abilities, co‐occurring psychopathologies, other aspects functioning. Results Four identified: Engaged n 247), exhibiting fewest challenges across each area; Inhibited 143), high mild few maintaining; Aloof 68), seeking but relatively low reticence; Avoidant 52), highest all areas. Subgroups did not differ terms chronological age or sex. The exhibited functioning while greatest challenges, profiles falling between. Conclusions highlights heterogeneous nature benchmarks, suggesting potential avenues for tailored interventions aimed at addressing specific experienced individuals within subgroup. Nevertheless, there remains need develop more refined tools capable capturing even finer‐grained expressions facilitating further characterization individual diagnostic boundaries.

Chronic stress remodels brain homeostasis, in which persistent change leads to depressive disorders1. As a key modulator of homeostasis2, it remains elusive whether and how autophagy is engaged dynamics. Here we discover that acute activates, whereas chronic suppresses, mainly the lateral habenula (LHb). Systemic administration distinct antidepressant drugs similarly restores function LHb, suggesting LHb as common target. Genetic ablation neuronal promotes susceptibility, enhancing exerts rapid antidepressant-like effects. controls excitability, synaptic transmission plasticity by means on-demand degradation glutamate receptors.
