The ability of differently structured, purified peptidoglycans (PG) to induce interleukin 1 (IL1) secretion was compared. PG from Bacillus megaterium and Staphylococcus aureus stimulated the production of IL1 by mouse peritoneal macrophages and human adherent mononuclear cells, whereas PG from Micrococcus lysodeikticus and Corynebacterium poinsettiae were inactive. There was a correlation between the ability of PG to induce IL1 secretion and previously demonstrated immunoenhancing activities (adjuvant effect, increase of resistance to tumor growth) of PG. PG solubilization by lysozyme decreased but did not abolish the PG effect on IL1 secretion. Active PG induced IL1 production in nude mice and in the C3H/HeJ strain (which is unresponsive to lipopolysaccharides).
比较了不同结构的纯化肽聚糖(PG)诱导白细胞介素1(IL1)分泌的能力。巨大芽孢杆菌和金黄色葡萄球菌的PG刺激小鼠腹腔巨噬细胞和人贴壁单核细胞产生IL1,而溶壁微球菌和猩猩棒状杆菌的PG则无活性。PG诱导IL1分泌的能力与先前证明的PG免疫增强活性(佐剂效应、增强对肿瘤生长的抵抗力)之间存在相关性。溶菌酶使PG溶解可降低但并未消除PG对IL1分泌的作用。活性PG可在裸鼠和C3H/HeJ品系(对脂多糖无反应)中诱导IL1产生。
