The use of multiplexing to identify cytokine and chemokine networks in the immune-inflammatory response to trauma.

Abstract

SIGNIFICANCE\nThe immune-inflammatory responses that follow trauma contribute to clinical trajectory and patient outcomes. While remarkable advances have been made in trauma services and injury management, clarity on how the immune system in humans responds to trauma is lagging behind. Recent Advances : Multiplexing platforms have transformed our ability to analyze comprehensive immune mediator responses in human trauma. In parallel, with the establishment of large datasets, computational methods have been adapted to yield new insights based on mediator patterns. These efforts have added an important data layer to the emerging multi-omic characterization of the human response to injury.\n\n\nCRITICAL ISSUES\nOutcome after trauma is greatly affected by the host immune-inflammatory response. Excessive or sustained responses can contribute to organ damage. Hence, understanding the pathophysiology behind traumatic injury is of vital importance.\n\n\nFUTURE DIRECTIONS\nThis review summarizes our work in the study of circulating immune mediators in trauma patients. Our foundational studies into mediator levels represent an important contribution to the concepts and computational challenges that these large datasets present. We hope to see further integration and understanding of multi-omics strategies in the field of trauma that can aid in patient endotyping and in potentially identifiying certain therapeutic targets in the future.
