We investigated the association of age and CM experiences with ELOVL2 methylation in peripheral blood mononuclear cells (PBMC). Furthermore, we investigated ELOVL2 methylation in the umbilical cord blood mononuclear cells (UBMC) of newborns of mothers with and without CM. PBMC and UBMC were isolated from 113 mother “newborn dyads and genomic DNA was extracted. Mothers with and without CM experiences were recruited directly postpartum. Mass array spectrometry and pyrosequencing were used for methylation analyses of ELOVL2 intron 1, and exon 1 and 5 2 end, respectively. ELOVL2 5 2 end and intron 1 methylation increased with higher age but were not associated with CM experiences. On the contrary, overall ELOVL2 exon 1 methylation increased with higher CM, but these changes were minimal and did not increase with age. Maternal CM experiences and neonatal methylation of ELOVL2 intron 1 or exon 1 were not significantly correlated. Our study suggests region-specific effects of chronological age and experienced CM on ELOVL2 methylation and shows that the epigenetic biomarker for age within the ELOVL2 gene does not show accelerated biological aging years after CM exposure.

History of child maltreatment and telomere length in immune cell subsets: Associations with stress- and attachment-related hormones / Christina BOECK in Development and Psychopathology, 30-2 (May 2018)  

Public ISBD [article]  inDevelopment and Psychopathology > 30-2 (May 2018) . - p.539-551 Titre : History of child maltreatment and telomere length in immune cell subsets: Associations with stress- and attachment-related hormones Type de document : Texte imprimé et/ou numérique Auteurs : Christina BOECK, Auteur ; Sabrina KRAUSE, Auteur ; Alexander KARABATSIAKIS, Auteur ; Katharina SCHURY, Auteur ; Harald GÜNDEL, Auteur ; Christiane WALLER, Auteur ; Iris-Tatjana KOLASSA, Auteur Article en page(s) : p.539-551 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Experiencing maltreatment during childhood can have long-lasting consequences for both mental and physical health. Immune cell telomere length (TL) shortening might be one link between child maltreatment (CM) experiences and adverse health outcomes later in life. While the stress hormone cortisol has been associated with TL attrition, the attachment-related hormone oxytocin may promote resilience. In 15 mothers with and 15 age- and body mass index-matched mothers without CM, we assessed TL in peripheral blood mononuclear cells and selected immune cell subsets (monocytes, naive, and memory cytotoxic T cells) by quantitative fluorescence in situ hybridization, as well as peripheral cortisol and oxytocin levels. Memory cytotoxic T cells showed significantly shorter TL in association with CM, whereas TL in monocytes and naive cytotoxic T cells did not significantly differ between the two groups. Across both groups, cortisol was negatively associated with TL, while oxytocin was positively associated with TL in memory cytotoxic T cells. These results indicate that long-lived memory cytotoxic T cells are most affected by the increased biological stress state associated with CM. Keeping in mind the correlational and preliminary nature of the results, the data suggest that cortisol may have a damaging and oxytocin a protective function on TL.
