Mast cells (MCs) comprise two lineages that differ in tissue localization and ontologic origin. Derakhshan et al. define the transcriptomes of these lineages during airway inflammation, identifying distinct programs associated with each lineage and a role for TGF-β signaling in inducible MC development.


Jagn1 deficiency results in alterations in the endoplasmic reticulum (ER) and Golgi apparatus of antibody-producing cells, reduced antibody secretion, and aberrant IgG N-glycosylation. The data uncover a key role for JAGN1 and ER stress in antibody glycosylation and humoral immunity in mice and humans.
