N-acetylmuramyl-L-alanyl-D-isoglutamine (MDP), an apparently nonimmunogenic bacterial peptidoglycan-derived small peptide, was found to induce a polyarthritis the rat similar to that induced by Freund's complete adjuvant when injected in the form of an oil emulsion. An oil emulsion of its isomer, N-acetylmuramyl-L-alanyl-L-isoglutamine, which unlike MDP has no immunostimulatory activity, failed to induce the disease.
N-乙酰胞壁酰-L-丙氨酰-D-异谷氨酰胺(MDP)是一种明显无免疫原性的细菌肽聚糖衍生小肽,当以油乳剂形式注射时,发现它能在大鼠中诱发一种类似于弗氏完全佐剂诱发的多关节炎。其异构体N-乙酰胞壁酰-L-丙氨酰-L-异谷氨酰胺的油乳剂,与MDP不同,没有免疫刺激活性,不能诱发该病。
