The Conserved Transcriptional Response to Adversity
Abstract
Gene expression profiling studies of people exposed to chronic threat have identified a Conserved Transcriptional Response to Adversity (CTRA) in circulating immune cells. This physiological pattern is characterized by up-regulated expression of genes involved in inflammation and down-regulated expression of genes involved in Type I interferon responses. The CTRA is mediated by beta-adrenergic signaling pathways that transduce sympathetic nervous system activity into changes in transcription factor activity and hematopoietic output of myeloid lineage immune cells (monocytes, neutrophils, and dendritic cells). Recent research has begun to identify the CNS processes that regulate peripheral CTRA activity, define its implications for disease, and explore the role of positive psychosocial factors in buffering such effects. The CTRA provides a genomic framework for understanding PNI relationships and connecting macro-level psychosocial processes to the micro-level biology of health and disease.
