Abstract

Age-related concentrations of myelin basic protein serum factor (MBP-SF), an endogenous neuroantigen detected and quantitated by inhibition of binding of rat myelin basic protein (RMBP) antibody with 125I-RMBP reagent antigen and immunochemically indistinguishable from native RMBP in this respect, reach peak levels as high as 21 ng/microliter among 2-3-wk-old normal suckling Lewis rats. Levels then progressively decline to low, usually undetectable levels of less than or equal to 0.6 ng/microliter MBP-equivalents in adult animals by 7 wk of age. MBP-SF levels are inversely related to the age-related increasing capacity of maturing Lewis rats to develop experimental allergic encephalomyelitis (EAE) after sensitization to MBP of syngeneic, but not xenogeneic, origin. MBP-SF appears to be an endogenous neuroimmunoregulatory product of potential importance for immunologic tolerance to autologous RMBP in Lewis rats.

摘要

髓鞘碱性蛋白血清因子(MBP - SF)是一种内源性神经抗原,通过抑制大鼠髓鞘碱性蛋白(RMBP)抗体与¹²⁵I - RMBP试剂抗原的结合来检测和定量,在这方面与天然RMBP在免疫化学上难以区分。在2至3周龄的正常哺乳Lewis大鼠中,与年龄相关的MBP - SF浓度达到峰值水平,高达21纳克/微升。到7周龄时,其水平随后逐渐下降至成年动物中低水平,通常低于或等于0.6纳克/微升MBP当量,通常无法检测到。MBP - SF水平与成熟Lewis大鼠在对同基因而非异种来源的MBP致敏后发生实验性变应性脑脊髓炎(EAE)的年龄相关增加能力呈负相关。MBP - SF似乎是一种内源性神经免疫调节产物,对Lewis大鼠对自身RMBP的免疫耐受具有潜在重要性。
