The Role of Th-17 Cells and γδ T-Cells in Modulating the Systemic Inflammatory Response to Severe Burn Injury

Burns are a global public health problem, accounting for an estimated 265,000 deaths annually. Inflammation is essential in supplying the growth factors, cytokines and chemokines needed to recruit T-cells and myeloid cells to the site of a burn injury for wound healing. However, major burns generate a marked pathophysiological inflammatory response through a widespread release of abundant pro-inflammatory mediators that predispose patients to a systemic inflammatory response syndrome, sepsis and multi-organ failure. Recently, there has been promising investigation into the role of γδ T-cells and Th-17 cells in the regulation and propagation of this inflammatory response. This study reviews the current literature on the post-burn immune response.
