Procedure for assessing myeloperoxidase and inflammatory mediator responses in hairless mouse skin

J Appl Toxicol. 2000 Dec:20 Suppl 1:S137-9. doi: 10.1002/1099-1263(200012)20:1+<::aid-jat667>3.0.co;2-d.

Abstract

A preparation procedure for making multiple inflammatory biomarker measurements from the same skin tissue was assessed. The backs of euthymic hairless mice were exposed to sulfur mustard (HD) vapor for 6 min. Animals were euthanized 24 h following exposure, dorsal skin tissue was excised and 12-mm, full-thickness biopsy punches of the exposed skin sites were taken. Specimens were snap-frozen, crushed to a powder using a biopulverizer unit, solubilized in buffer and centrifuged. Supernatant was assayed for pro-inflammatory cytokines and the acute-phase reactive protein, serum amyloid P (SAP). Myeloperoxidase (MPX), which is indicative of neutrophil infiltration into the skin, was associated with the pellet fraction. Results indicate an elevation of interleukin-6, SAP and MPX in mouse skin tissue specimens 24h following HD vapor exposure. The tissue preparation procedure allows the use of a single skin specimen to make multiple inflammatory endpoint measurements requiring different preparation processes, and it will be used in subsequent studies to characterize further the inflammatory nature of HD-exposed skin tissue.
