Abstract
Dendritic cells (DC) are a heterogeneous population of specialized antigen presenting cells that exhibit complex trafficking properties. DC differentiated in vitro from both peripheral monocytes and CD34+ cells expressed mRNA for platelet activating factor (PAF) receptor. Expression of PAF receptor was increased by TNF alpha, a prototypic inflammatory cytokine that induces differentiation and in vivo mobilization of DC. PAF induced in vitro directional migration of DC obtained from both precursor cells through its specific receptor. Since DC are highly motile cells, protein chemoattractants as well as bioactive phospholipids are likely to contribute to tissue localization of DC, in vivo.
