The fate of CD8+ T cells during infection is linked to their developmental origin [Naïve_Timestamp]

Project description:During immune ontogeny the thymus is colonized by distinct waves of hematopoietic stem cells that give rise to unique lineages of immune cells. In this report, we asked whether the developmental origin of CD8+ T cells influences their response to infection later in adulthood. To answer this question, we developed a system to ‘timestamp’ CD8+ T cells in situ at various stages of development (1d and 28d) and examined their behavior at 8 weeks of age. We found that neonatal-derived CD8+ T cells have an intrinsic propensity to become memory phenotype cells prior to infection and are the first cells to proliferate and become effectors after microbial challenge. These data indicate that there are developmental layers in the adult CD8+ T cell response to infection and that the heterogeneity in the effector pool is linked to the variation in the developmental origins of the responding cells. This dataset profiles gene expression in 1day- and 28day-timestamped naïve CD8+ T cells in 8 week old mice.

To answer this question, we developed a system to ‘timestamp’ CD8+ T cells in situ at various stages of development (1d and 28d) and examined their behavior after post-thymic differentiation.

This dataset profiles chromatin accessibility in 1day- and 28day-timestamped virtual memory (CD44hi) and "true naive" (CD44 lo) CD8+ T cells in cells that had undergone the same amount of post-thymic maturation (4 weeks, transgenic mice, different sorts).

This dataset profiles gene expression in 1day- and 28day-timestamped virtual memory (CD44hi) CD8+ T cells aged for 4 weeks of post-thymic differentiation and then transferred into congenically marked recipients. Timestamped cells were recovered 5 days following infection with Listeria monocytogenes.

Hemogenic endothelial fate mapping reveals dual developmental origin of mast cells.

Project description:Hematopoiesis occurs in distinct waves. ‘Definitive’ hematopoietic stem cells (HSC) with the potential for all blood lineages emerge in the aorta-gonado-mesonephros (AGM), while ‘primitive’ progenitors, whose potential is thought to be limited to erythrocytes, megakaryocytes and macrophages (MΦ), arise earlier in the yolk sac (YS). Here, we questioned whether other YS lineages exist that have not been identified, partially owing to limitations of current lineage tracing models. We established the use of Cdh5CreERT2 for hematopoietic fate mapping, which revealed the YS origin of mast cells (MC). YS derived MC are replaced by definitive MC, which maintain themselves independently from the BM in the adult. Replacement occurs with tissue specific kinetics. MC in the skin, but not other organs, remain largely YS derived prenatally and are phenotypically and transcriptomically distinct from definite adult MC. We conclude that dual hematopoietic origin is not MΦ specific, but shared between these two myeloid lineages.
