Allergens induce type-2 immunity, but unresolved questions remain about initiation of this response. In this issue, Perner et al. propose that cutaneous activation of TRPV1 sensory neurons by protease allergens stimulates release of substance P to induce migration of Th2-skewing CD301b DC to draining lymph nodes.
过敏原会引发 2 型免疫,但关于该反应的启动仍存在一些悬而未决的问题。在本期杂志中,Perner 等人提出,蛋白酶过敏原激活皮肤中的 TRPV1 感觉神经元会刺激 P 物质的释放,从而诱导偏向 Th2 的 CD301b DC 向引流淋巴结迁移。
