Cytokines play a major role in both acute and chronic inflammatory processes, including those produced by sulfur mustard (HD). This study describes responses of normal human epidermal keratinocyte (NHEK) cells to 2,2'-dichlorodiethyl sulfide, sulfur mustard (HD), defined by interleukin-1 beta (IL-1beta), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNF-alpha) release. A new method for detaching cell to cell adhesion between keratinocytes has been applied. ⋯ IL-6 was released in a concentration-dependent manner, 3.6-fold up to 8.4-fold, respectively, in supernatant. These pro-inflammatory mediators IL-1beta, IL-8, TNF-alpha and IL-6 may play an important role in HD injury. The present findings suggest that cytokine changes detected could be used as potential biomarkers of cutaneous vesicant injury.
