Significant ( P < .05 ) decreases in mRNA expression of genes related to hyperplasia ( K16 and MKI67 ) , T cells , and dendritic cells ( CD1b and CD1c ) and potent inhibition of TH2-associated chemokines ( CCL17 , CCL18 , CCL22 , and CCL26 ) were noted without significant modulation of TH1-associated genes ( IFNG ) .
