TL;DR: This refined analysis has identified, among others, a previously unknown dendritic cell population that potently activates T cells and reclassify pDCs as the originally described “natural interferon-producing cells (IPCs)” with weaker T cell proliferation induction ability.

TL;DR: In this paper, the authors performed single-cell RNA sequencing of ~2400 cells isolated from healthy blood donors and enriched for HLA-DR + lineage − cells, which led them to identify and validate six Dendritic cells (DCs) and four monocyte subtypes.

TL;DR: A shift in the haemopoietic composition of fetal liver during gestation away from being predominantly erythroid, accompanied by a parallel change in differentiation potential of HSC/MPPs is demonstrated, which is validated to produce an integrated map of fetal liver haematopoiesis.

TL;DR: In this paper, the transcriptomes of more than 500,000 single cells from developing human fetal skin, healthy adult skin, and adult skin with atopic dermatitis and psoriasis were compared across development, homeostasis, and disease.

TL;DR: The innate immune response’s transcriptional divergence between species and variability in expression among cells is characterized, suggesting that this expression pattern has evolved as a mechanism for fine-tuned regulation to achieve an effective but balanced response.
