In vivo and in absence of a thymus, the enforced expression of the Notch ligands delta-1 or delta-4 promotes T cell development with specific unique effects.
Abstract : The role of Notch signaling in T cell commitment during lymphoid development is well established. However, the identity of the ligand that triggers this critical signal in vivo is still unclear. By overexpressing Delta-1 and Delta-4 ligands in the hemopoietic cells of athymic nu/nu host mice, we demonstrate that, in vivo and in the absence of a thymus, Delta-1 or Delta-4 expression is sufficient to promote T cell development from the most immature progenitor stages to complete maturation of both CD8(+) and CD4(+) alphabeta T cells. The mature T cells developing in a Delta-1- or Delta-4-enriched environment express a diverse TCR repertoire, are able to proliferate upon in vitro TCR stimulation, but show different profiles of cytokine production after in vitro anti-CD3 stimulation.
