The macaque Social Responsiveness Scale was previously adapted from the Social Responsiveness Scale, an instrument designed to assess social and autistic trait variation in humans. To better understand potential biological underpinnings of this behavioral variation, we evaluated the trait-like consistency of several biological measures previously implicated in autism (e.g., arginine vasopressin, oxytocin, and their receptors, as well as ERK1/2, PTEN, and AKT(1-3) from the RAS-MAPK and PI3K-AKT pathways). We also tested which biological measures predicted macaque Social Responsiveness Scale-Revised scores. METHODS: Cerebrospinal fluid and blood samples were collected from N = 76 male monkeys, which, as a sample, showed a continuous distribution on the macaque Social Responsiveness Scale-Revised. In a subset of these subjects (n = 43), samples were collected thrice over a 10-month period. The following statistical tests were used: "Case 2A" intra-class correlation coefficients of consistency, principal component analysis, and general linear modeling. RESULTS: All biological measures (except AKT) showed significant test-retest reliability within individuals across time points. We next performed principal component analysis on data from monkeys with complete biological measurement sets at the first time point (n = 57), to explore potential correlations between the reliable biological measures and their relationship to macaque Social Responsiveness Scale-Revised score; a three-component solution was found. Follow-up analyses revealed that cerebrospinal fluid arginine vasopressin concentration, but no other biological measure, robustly predicted individual differences in macaque Social Responsiveness Scale-Revised scores, such that monkeys with the lowest cerebrospinal fluid arginine vasopressin concentration exhibited the greatest social impairment. Finally, we confirmed that this result held in the larger study sample (in which cerebrospinal fluid arginine vasopressin values were available from n = 75 of the subjects). CONCLUSIONS: These findings indicate that cerebrospinal fluid arginine vasopressin concentration is a stable trait-like measure and that it is linked to quantitative social trait variation in male rhesus monkeys.

Blood oxytocin concentration positively predicts contagious yawning behavior in children with autism spectrum disorder / Michael G. MARISCAL in Autism Research, 12-8 (August 2019)

PARKER, Auteur Article en page(s) : p.1156-1161 Langues : Anglais (eng) Mots-clés : autism  contagion  empathy  oxytocin  social functioning  yawning Index. décimale : PER Périodiques Résumé : Research suggests that children with autism spectrum disorder (ASD) may have reduced empathy, as measured by an impaired contagious yawn response, compared to typically developing (TD) children. Other research has failed to replicate this finding, instead attributing this phenomenon to group differences in attention paid to yawn stimuli. A third possibility is that only a subgroup of children with ASD exhibits the impaired contagious yawn response, and that it can be identified biologically. Here we quantified blood concentrations of the "social" neuropeptide oxytocin (OXT) and evaluated yawning behavior and attention rates during a laboratory task in children with ASD (N = 34) and TD children (N = 30) aged 6-12 years. No group difference in contagious yawning behavior was found. However, a blood OXT concentration x group (ASD vs. TD) interaction positively predicted contagious yawning behavior (F1,50 = 7.4987; P = 0.0085). Specifically, blood OXT concentration was positively related to contagious yawning behavior in children with ASD, but not in TD children. This finding was not due to delayed perception of yawn stimuli and was observed whether attention paid to test stimuli and clinical symptom severity were included in the analysis or not. These findings suggest that only a biologically defined subset of children with ASD exhibits reduced empathy, as measured by the impaired contagious yawn response, and that prior conflicting reports of this behavioral phenomenon may be attributable, at least in part, to variable mean OXT concentrations across different ASD study cohorts. Autism Res 2019, 12: 1156-1161. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: People with autism may contagiously yawn (i.e., yawn in response to another's yawn) less often than people without autism. We find that people with autism who have lower levels of blood oxytocin (OXT), a hormone involved in social behavior and empathy, show decreased contagious yawning, but those who have higher blood OXT levels do not differ in contagious yawning from controls. This suggests that decreased contagious yawning may only occur in a biologically defined subset of people with autism.

Cerebrospinal Fluid Vasopressin Concentration Is a Biomarker of Autistic Social Impairment and Hypothalamic Vasopressin Gene Expression in Humans / Ozge OZTAN in Autism Research, 19-3 (March 2026)

Recent ASD biomarker discovery efforts have found that cerebrospinal fluid (CSF) concentration of vasopressin, a hypothalamic neuropeptide critical for mammalian social functioning, is significantly lower in children with ASD and newborns later diagnosed with ASD. Low CSF vasopressin concentration is also linked to ASD social (but not repetitive) behavior symptom severity. These findings suggest that CSF vasopressin measurement may have clinical utility, but CSF surveillance requires invasive sampling procedures that will be difficult to integrate into routine clinical care without strong justification (i.e., CSF vasopressin is a valid proxy for hypothalamic vasopressin production, whereas blood vasopressin is not). We therefore obtained neuropathological specimens and patient data (N?=?18) to investigate this possibility. In Study 1, we capitalized on the unique opportunity to test the reproducibility and robustness of the relationship between CSF vasopressin concentration and ASD behavioral symptoms in a sample demographically and methodologically distinct from prior work. This relationship held across age, antemortem to postmortem biospecimens, quantification platforms, clinical instruments, evaluators, and symptom type. In Study 2, we found in concomitantly collected postmortem samples that CSF vasopressin concentration significantly and positively predicted hypothalamic vasopressin gene expression, whereas blood vasopressin concentration did not. These findings establish CSF vasopressin as a brain-derived, mechanistically relevant biomarker of social difficulties in ASD, and suggest that CSF vasopressin measurement may be useful for ASD detection and/or identification of individuals who will benefit from pharmacological enhancement of brain vasopressin signaling.

Naturally occurring low sociality in female rhesus monkeys: A tractable model for autism or not? / Ozge OZTAN in Molecular Autism, 15 (2024)

Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder (ASD) is characterized by persistent social interaction impairments and is male-biased in prevalence. We have established naturally occurring low sociality in male rhesus monkeys as a model for the social features of ASD. Low-social male monkeys exhibit reduced social interactions and increased autistic-like trait burden, with both measures highly correlated and strongly linked to low cerebrospinal fluid (CSF) arginine vasopressin (AVP) concentration. Little is known, however, about the behavioral and neurochemical profiles of female rhesus monkeys, and whether low sociality in females is a tractable model for ASD. METHODS: Social behavior assessments (ethological observations; a reverse-translated autistic trait measurement scale, the macaque Social Responsiveness Scale-Revised [mSRS-R]) were completed on N = 88 outdoor-housed female rhesus monkeys during the non-breeding season. CSF and blood samples were collected from a subset of N = 16 monkeys across the frequency distribution of non-social behavior, and AVP and oxytocin (OXT) concentrations were quantified. Data were analyzed using general linear models. RESULTS: Non-social behavior frequency and mSRS-R scores were continuously distributed across the general female monkey population, as previously found for male monkeys. However, dominance rank significantly predicted mSRS-R scores in females, with higher-ranking individuals showing fewer autistic-like traits, a relationship not previously observed in males from this colony. Females differed from males in several other respects: Social behavior frequencies were unrelated to mSRS-R scores, and AVP concentration was unrelated to any social behavior measure. Blood and CSF concentrations of AVP were positively correlated in females; no significant relationship involving any OXT measure was found. LIMITATIONS: This study sample was small, and did not consider genetic, environmental, or other neurochemical measures that may be related to female mSRS-R scores. CONCLUSIONS: Dominance rank is the most significant predictor of autistic-like traits in female rhesus monkeys, and CSF neuropeptide concentrations are unrelated to measures of female social functioning (in contrast to prior CSF AVP findings in male rhesus monkeys and male and female autistic children). Although preliminary, this evidence suggests that the strong matrilineal organization of this species may limit the usefulness of low sociality in female rhesus monkeys as a tractable model for ASD.
