KAT14 and pemphigus foliaceus: Five genes were found to be differently expressed in CD4+ T cells from patients with EPF without oral corticoid treatment and presenting active disease, compared to controls from PF endemic regions: ZEB2 (zinc finger E-box binding homeobox 2), KAT2B (lysine acetyltransferase 2B), and PHF20 (PHD finger protein 20) were overexpressed in patients, while KAT14 (lysine acetyltransferase 14) and JADE1 (jade family PHD finger 1) were underexpressed (Table 3).
