Bactericidal/permeability-increasing protein is expressed by human dermal fibroblasts and upregulated by interleukin 4.
The bactericidal/permeability-increasing protein (BPI) is an antibiotic- and endotoxin-neutralizing protein of granulocytes and epithelial cells. Constitutive expression of BPI, which increases upon interleukin 4 stimulation, by human dermal fibroblast was demonstrated, suggesting an important role of BPI in gram-negative bacterial clearance and a dampened response to endotoxin in the skin.
