- Cutting down the hematopoietic tree: E-cadherin reveals a landscape of differentiating basophils and mast cells
GATA-2–mediated E-cadherin expression marks early progenitors primed to the basophil and mast cell lineages in mouse hematopoiesis (see the related Research Article by Wanet et al.).
Research Articles
- Continuous human uterine NK cell differentiation in response to endometrial regeneration and pregnancy
Human uterine NK cells continuously differentiate in response to the monthly regeneration of the endometrium and during pregnancy.
- Innate cell microenvironments in lymph nodes shape the generation of T cell responses during type I inflammation
Distinct myeloid cell microenvironments in LNs promote divergent T cell programming during type I inflammation.
- E-cadherin is regulated by GATA-2 and marks the early commitment of mouse hematopoietic progenitors to the basophil and mast cell fates
E-cadherin expression on mouse hematopoietic progenitors marks their commitment to the basophil and mast cell fates at an early stage.
- IL-17 controls central nervous system autoimmunity through the intestinal microbiome
IL-17 is a key safeguard of intestinal homeostasis, indirectly modulating the autoimmune response against CNS antigens.

- TregGF-β: Deletion of TGF-β in Tregs revisited
Treg-specific ablation of TGF-β clarifies the complicated role of Treg-derived TGF-β in immunosuppression in vivo.
- Basophils getting on your nerves? Itching for clarity on flares in atopic dermatitis
Flares of acute itch in the setting of atopic dermatitis may engage a novel neuroimmune axis that includes basophils, LTC4, and sensory neurons.
About The Cover
ONLINE COVER Progenitor Potential. This month's cover shows granule-bearing mouse mast cells derived from a 14-day in vitro culture of E-cadherin–expressing progenitor cells isolated from bone marrow. Wanet et al. identified E-cadherin as an early GATA-2–regulated marker of basophil and mast cell progenitor cell populations that was maintained as these two hematopoietic lineages matured. A Focus commentary by Dahlin discusses where the pro-BMP and pre-BMP populations characterized by Wanet et al. fit within a landscape model of hematopoietic cell differentiation.
