This study demonstrates that fetal mast cells can be sensitized by maternal IgE crossing the placenta via Fc receptors. These sensitized cells remain reactive after birth, leading to stronger allergic responses upon first exposure to allergens. The findings suggest that allergies may partly originate before birth, redefining how early-life immune programming is understood.
DescriptionThe study shows that blocking GM-CSF reduces liver fibrosis by limiting CD206+ macrophage accumulation. This suggests a promising therapeutic pathway....
This paper identifies a subset of dendritic cells (cDC1s) that regulate bacterial infections by recruiting neutrophils through VEGFα secretion. It....
This research reveals that epidermal γδ T cells originate from yolk sac hematopoiesis rather than traditional stem cells. These cells....
