Pertussis toxin (PTX) is an exotoxin produced by Bordetella pertussis. It is known to exert adjuvant activities inducing Th1-launched immune responses. In this study, we show that PTX can selectively block the expression of CD1a isoform during the differentiation of human monocytes into dendritic cells. In fact, dendritic cells differentiated from monocytes in the presence of PTX do not express CD1a on their surface, unlike CD1b and CD1c isoforms, which are normally regulated. The impaired CD1a expression on cell membrane depends, at least partially, on decreased mRNA transcription and does not affect cellular capability to respond to other maturation stimuli. Since CD1a(+) dendritic cells are involved in the early steps of primary immune response, the interference of PTX in the CD1a expression may be relevant for its employment as adjuvant.
