脾切除和脾切除的患者被包裹的细菌感染的发生率很高,对多糖疫苗没有反应。为了了解脾的缺失是否与明确的B细胞缺陷有关,我们分析了外周血中的B细胞亚群。我们发现,在没有脾的患者中,一种称为免疫球蛋白(Ig)M记忆的B细胞群体缺乏。IgM记忆B细胞的缺失不仅与脾切除患者对包裹细菌的免疫反应受损有关,也与脾完整的个体的免疫反应受损有关。我们发现,幼儿(0-2岁)对肺炎球菌感染的生理性和暂时性易感性与循环中的IgM记忆B细胞和血清抗多糖IgM的缺乏有关。我们还证明,在一小部分常见变量免疫缺陷患者中,IgM记忆B细胞是检测不到的,这些患者有被包裹的细菌反复和侵袭性感染。因此,IGM Memory B细胞的生成和/或生存需要脾,并负责保护其免受被包裹的细菌的侵袭。
Splenectomized and asplenic patients have a high incidence of infections by encapsulated bacteria and do not respond to polysaccharide vaccines. To understand whether the absence of the spleen is associated with a defined B cell defect, we analyzed B cell subsets in the peripheral blood. We found that a population of B cells known as immunoglobulin (Ig)M memory is lacking in patients without spleen. The absence of IgM memory B cells correlates with an impaired immune response to encapsulated bacteria not only in splenectomized patients, but also in individuals with an intact spleen. We show that the physiological and transient predisposition to pneumococcal infections of young children (0–2 yr) is associated with the lack of circulating IgM memory B cells and of serum antipolysaccharide IgM. We also demonstrate that IgM memory B cells are undetectable in a fraction of patients with common variable immunodeficiency, who have recurrent and invasive infections by encapsulated bacteria. IgM memory B cells, therefore, require the spleen for their generation and/or survival and are responsible for the protection against encapsulated bacteria.
