Abstract

Here, we review the functional roles of cyclic ADP-ribose and CD38, a transmembrane protein with ADP-ribosyl cyclase activity, in mouse social behavior via the regulation of oxytocin (OXT) release, an essential component of social cognition. Herein we describe data detailing the molecular mechanism of CD38-dependent OXT secretion in CD38 knockout mice. We also review studies that used OXT, OXT receptor (OXTR), or CD38 knockout mice. Additionally, we compare the behavioral impairments that occur in these knockout mice in relation to the OXT system and CD38. This review also examines autism spectrum disorder (ASD), which is characterized by social and communication impairments, in relation to defects in the OXT system. Two single nucleotide polymorphisms (SNPs) in the human CD38 gene are possible risk factors for ASD via inhibition of OXT function. Further analysis of CD38 in relation to the OXT system may provide a better understanding of the neuroendocrinological roles of OXT and CD38 in the hypothalamus and of the pathophysiology of ASD. This article is part of a Special Issue entitled Oxytocin, Vasopressin, and Social Behavior.

TL;DR

This review argues that CD38, via cyclic ADP-ribose and calcium signaling, is required for oxytocin secretion and normal social behavior in mice, and that human CD38 variants may contribute to autism spectrum disorder (ASD) risk. It summarizes CD38, OXT, and OXTR knockout mouse phenotypes plus human CD38 SNP and plasma OXT findings.

Key findings

  • CD38 knockout mice show social and maternal behavioral deficits: CD38−/− pups emitted fewer ultrasonic vocalizations per 2-min session (average reduction 38%) than wild-type controls, and CD38−/− dams had longer pup-retrieval latency (76 ± 8 s) than wild-type dams (43 ± 3 s; p < 0.01).
  • CD38−/− mice have reduced plasma and cerebrospinal fluid OXT levels but elevated hypothalamic/pituitary OXT, and the phenotype was normalized by subcutaneous OXT injection or viral re-expression of human CD38.
  • In humans, the CD38 intronic SNP rs3796863 was significantly associated with high-functioning autism in American subjects (p < 0.005, n = 104), while the exonic R140W SNP was found in 3 of 29 ASD subjects (10.3%) versus 3 of 315 controls (allelic frequency 0.0048; ASD frequency 0.052; p < 0.029).
  • Plasma OXT was lower in R140W carriers (161.3 ± 26.5 pg/ml, n = 12) than in non-carrier relatives (345.8 ± 61.3 pg/ml, n = 10; p < 0.01); among ASD subjects, five R140W carriers had lower OXT (79.2 ± 16.6 pg/ml) than ASD subjects lacking the mutation (147.7 ± 15.0 pg/ml; p < 0.01, n = 26) and than 101 control adults (198.2 ± 24.7 pg/ml; p < 0.01).

Methods

  • Narrative review of mouse and human studies on CD38, cADPR, OXT, OXTR, and social behavior, including CD38−/−, Oxt−/−, and Oxtr−/− mouse models.
  • Human data included CD38 mRNA/protein expression in brain, CD38 SNP screening in 29 unrelated ASD subjects and 201 non-clinical controls from Kanazawa, additional ASD/control cohorts, 252 trios and 104 HFA trios, 315 healthy controls, and three R140W proband families.
  • Analyses summarized include genetic association, haplotype transmission disequilibrium testing, clinical/AQ evaluation, and plasma OXT/AVP measurements in carriers versus non-carriers.

Limitations

  • The paper states that many fundamental questions remain: whether CD38 activity is sensitive to environmental and social contexts, whether CD38–ASD association implies immunological irregularity, and which additional molecules interact with CD38 to regulate OXT secretion.
  • The paper notes that the intronic SNP’s functional importance remains to be determined, that the fetal/infant exogenous-OXT hypothesis needs empirical testing, and that larger-scale studies with increased statistical power are warranted.
  • Evident from the text: this is a review rather than a systematic primary study, some human analyses rely on small samples (e.g., 3 ASD families, 5 R140W ASD carriers), and mouse findings may not fully translate to human ASD pathophysiology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
