Making good of a tricky start: How IgE and mast cells manage a protective sway in food allergy

The immune and nervous systems respond to dangerous stimuli to maintain homeostasis. In a recent issue of Nature, Florsheim et al. and Plum et al. uncover the crosstalk between immunoglobulin E (IgE)-mast-cell-mediated immune activation and neural responses driving behavioral avoidance of allergenic food.
