Toll‐like receptor‐mediated eosinophil–basophil differentiation: autocrine signalling by granulocyte–macrophage colony‐stimulating factor in cord blood haematopoietic progenitors

Eosinophils are multi-functional leucocytes that play a role in inflammatory processes including allergy and infection. Although bone marrow (BM) inflammatory cells are the main source of eosinophil-basophil (Eo/B) differentiation-inducing cytokines, a recent role has been demonstrated for cytokine induction through Toll-like receptor (TLR)-mediated signalling in BM progenitors. Having previously demonstrated that cord blood (CB) progenitors …
