这篇讲什么
科学家发现,免疫系统中一条长期被忽视的CD1通路专门识别脂质而非蛋白质片段,可能解释毒藤皮疹、蜂蜇肿痛和尘螨过敏等反应。实验室研究显示,毒藤中的漆酚成分可与皮肤哨兵细胞上的CD1结合并激活T细胞,而CD1系统还与溃疡性结肠炎、克罗恩病乃至癌症监测有关。由于CD1蛋白种类远少于MHC蛋白,针对它的药物和疫苗可能具有更广的适用性。
原文开头
A little-known arm of the immune system respond to lipids, with a protein called CD1 driving reactions to bee stings, bacteria, and possibly poison ivy MITCH LESLIE For a hiker who unwittingly brushes the leaf of poison ivy, weeks of suffering can start within a few hours, when an itchy red rash appears at the contact site. In the days that follow, blisters erupt and the urge to scratch can become maddening. Even after the blisters begin to burst and crust over, the skin will need days more to heal. Unpleasant encounters with poison ivy and its noxious relatives are common, but they have long posed a biological puzzle. …
