回复霉素A(Rev.A)是一种表皮生长因子依赖性细胞生长的抑制剂,由放线菌菌株的培养液产生。评估了Rev. A调节携带三硝基苯基(TNP)特异性表面IgM(sIgM)的A20-HL B淋巴瘤细胞向OVA(323-339)/I-Ad特异性克隆T细胞呈递抗原(Ag)的能力。Rev. A处理抑制了通过sIgM内化的Ag呈递,但不抑制通过液相胞饮作用的Ag呈递。Rev. A处理降低了蛋白质合成,但放线菌酮引起的蛋白质合成的类似降低对sIgM介导的Ag呈递的抑制要小得多。Rev. A处理降低了A20-HL细胞中sIgM的再表达率、孵育3小时期间通过sIgM内化的Ag量以及通过sIgM内化的TNP-OVA产生的抗原肽。建议Rev. A处理影响从早期内体到晚期内吞隔室的通过sIgM内化的Ag的细胞内运输。Rev. A可能为研究Ag的细胞内转运,特别是通过sIgM内化的Ag提供有用的工具。
Reveromycin A (Rev.A) is an inhibitor of epidermal growth factor-dependent cell growth that is produced from the culture broth of an actinomycete strain. Rev.A was assessed for its ability to regulate antigen (Ag) presentation by A20-HL B lymphoma cells bearing trinitrophenyl (TNP)-specific surface IgM (sIgM) to cloned T cells specific for OVA(323-339)/I-Ad. Rev.A-treatment inhibited the presentation of Ag internalized via sIgM, but not of Ag via fluid-phase pinocytosis. Rev.A-treatment decreased protein synthesis, but a similar decrease in protein synthesis by cycloheximide induced much less inhibition of sIgM-mediated Ag presentation. Rev.A-treatment decreased the rate of re-expression of sIgM in A20-HL cells, the amount of Ag internalized via sIgM during 3 hours of incubation, and the generation of antigenic peptides from TNP-OVA internalized via sIgM. Rev.A-treatment was suggested to affect intracellular trafficking from early endosomes into late endocytic compartments of Ag internalized via sIgM. Rev.A might provide a useful tool for studying intracellular transport of Ag, especially Ag internalized via sIgM.
