Filamentous hemagglutinin (FHA) is an important adhesin of the whooping cough agent Bordetella pertussis and is contained in most acellular pertussis vaccines. Recently, FHA was proposed to exert an immunomodulatory activity through induction of tolerogenic IL-10 secretion from dendritic cells. We have re-evaluated the cytokine-inducing activity of FHA, placing specific emphasis on the role of the residual endotoxin contamination of FHA preparations. We show that endotoxin depletion did not affect the capacity of FHA to bind primary human monocyte-derived dendritic cells, while it abrogated the capacity of FHA to elicit TNF-alpha and IL-10 secretion and strongly reduced its capacity to trigger IL-6 production.
