Unexpected steps in plasma-cell differentiation.

abstract：:In allergic patients, small amounts of allergen activate mast cells and trigger an immune cascade that can result in anaphylactic shock. In a recent issue of Science, Choi et al. (2018) show that dendritic cells sample the lumen of blood vessels and use microvesicles to trigger mast cell degranulation and anaphylaxis....
