Beschreibung:
To identify molecular mechanisms by which early life social conditions might influence adult risk of disease in rhesus macaques (Macaca mulatta), we analyze changes in basal leukocyte gene expression profiles in 4-month-old animals reared under adverse social conditions. Compared to the basal condition of maternal rearing (MR), leukocytes from peer-reared (PR) animals and PR animals provided with an inanimate surrogate mother (surrogate/peer reared; SPR) show enhanced expression of genes involved in inflammation, cytokine signaling, and T lymphocyte activation, and suppression of genes involved in several innate antimicrobial defenses including Type I Interferon antiviral responses. Promoter-based bioinformatic analyses implicate increased activity of CREB and NF-kB transcription factors and decreased activity of Interferon Response Factors (IRFs) in structuring the observed differences in gene expression. Transcript origin analyses identify monocytes and CD4+ T lymphocytes as primary cellular mediators of transcriptional up-regulation and B lymphocytes as major sources of down-regulated genes. These findings show that adverse social conditions can become embedded within the basal transcriptome of primate immune cells within the first 4 months of life, and they implicate sympathetic nervous system-linked transcription control pathways as candidate mediators of those effects and potential targets for health-protective intervention.
