New research indicates that the social amoeba Dictyostelium discoideum recognizes distinctions between Gram(-) and Gram(+) bacterial prey and responds discriminately to these two groups of bacteria. These findings may lend insight to the origins of microbial pattern recognition in innate immunity.
新的研究表明，黏菌（Dictyostelium discoideum）能够区分革兰氏阴性和革兰氏阳性细菌猎物，并对这两组细菌做出有区别的反应。这些发现可能有助于深入了解先天免疫中微生物模式识别的起源。
