HaCaT cell monolayers were treated with 0.5 μg/ml HBD2 in serum free media for 24 h, before addition of 5 μg/ml V8, or vehicle control, for a further 24 h. Cells were then collected and centrifuged at 3000 rpm for 5 min. Dry cell pellet stored at -80 °C prior to analysis. n = 5 per condition. Log fold changes and p values generated using LIMMA pathway⁴³. Table shows proteins with the greatest differences in detection levels between HBD2-protected and unprotected cells after exposure to V8, largest to smallest with Uniprot protein code, gene code, fold change, p.mod value, protein name and brief description of function. Protein descriptions made using UniProt database information⁴⁶.
