The present study examined the specificity of guinea pig erythrocyte (E) and erythrocyte-antibody-complement (EAC) rosette formation assays with suspensions of canine peripheral blood lymphocytes. Neutrophils, monocytes, and lymphocytes bound EAC but not erythrocyte-antibody (EA) controls. Similarly, all three cell types formed rosettes with guinea pig E. Adherence of guinea pig E to these cells was apparently mediated by natural cytophilic antibodies present in the serum used in the suspension medium. The nonspecificity of the guinea pig E-rosette formation assay with canine lymphocytes renders the technique unreliable for the identification of thymus-derived lymphocytes in dogs.
本研究检测了豚鼠红细胞(E)和红细胞-抗体-补体(EAC)花环形成试验对犬外周血淋巴细胞悬液的特异性。中性粒细胞、单核细胞和淋巴细胞能结合EAC,但不能结合红细胞-抗体(EA)对照。同样,这三种细胞类型都能与豚鼠E形成花环。豚鼠E与这些细胞的黏附显然是由悬浮培养基中所用血清中存在的天然嗜细胞抗体介导的。豚鼠E花环形成试验对犬淋巴细胞的非特异性使得该技术在鉴定犬的胸腺来源淋巴细胞时不可靠。
