Glucocorticoid dexamethasone down-regulates basal and vitamin D3 induced cathelicidin expression in human monocytes and bronchial epithelial cell line

Highlights • Glucocorticoid (GC) dexamethasone down-regulates basal mRNA expression of the antimicrobial peptide genes CAMP (cathelicidin antimicrobial peptide), DEFB1 (human beta defensin 1), LZY (lysozyme) and SLPI (secretory leukocyte proteinase inhibitor 1) in THP-1 monocytes. • Dexamethasone re...

description Highlights • Glucocorticoid (GC) dexamethasone down-regulates basal mRNA expression of the antimicrobial peptide genes CAMP (cathelicidin antimicrobial peptide), DEFB1 (human beta defensin 1), LZY (lysozyme) and SLPI (secretory leukocyte proteinase inhibitor 1) in THP-1 monocytes. • Dexamethasone reduces vitamin D3 enhanced human cathelicidin ( CAMP ) gene expression in THP-1 monocytes, primary human monocytes and in the bronchial epithelial cell line BCi NS 1.1. • The Glucocorticoid receptor inhibitor RU486 prevents dexamethasone mediated inhibition of CAMP gene.
