我们比较了HLA-ABC(I类)和HLA-DR(II类)抗原在新鲜人供体角膜组织、在McCarey-Kaufman(M-K)培养基中储存72小时后的供体角膜、同种异体移植排斥和慢性疱疹性角膜基质炎患者的角膜扣上的分布。与新鲜组织相比,在M-K培养基中孵育对HLA抗原的分布几乎没有影响。与对照角膜相比,在角膜内皮细胞、基质细胞和排斥性同种异体移植物的基底上皮细胞上均检测到HLA I类和II类抗原。角膜内皮细胞在疱疹按钮没有表达可检测的HLA抗原。HLA-DR阳性Langerhan细胞在排斥反应角膜中央上皮和疱疹性角膜中均可见,而在对照角膜中除利姆布斯外均未见。基于这些观察结果,基于与细胞炎症相关的因子诱导供体纽扣中细胞上的I类HLA-ABC和II类HLA-DR抗原,提出了人类角膜同种异体移植排斥的理论。
We compared the distribution of HLA-ABC (class I) and HLA-DR (class II) antigens on fresh human donor corneal tissue, donor corneas following a 72-hour storage in McCarey-Kaufman (M-K) medium, and corneal buttons from patients with allograft rejection and with chronic herpetic stromal keratitis. Incubation in M-K media had little or no effect on the distribution of HLA antigens as compared with fresh tissue. In contrast to control corneas, both HLA class I and II antigens were detected on corneal endothelial cells, cells in the stroma, and on basal epithelial cells in rejected allografts. Corneal endothelium in herpetic buttons did not express detectable HLA antigens. HLA-DR positive Langerhan's cells were demonstrated in the central corneal epithelium of rejected allografts, as well as in herpetic corneas, but not in control corneas except at the limbus. Based upon these observations, a theory of corneal allograft rejection in humans is proposed based upon the induction of class I HLA-ABC and class II HLA-DR antigens on cells in the donor button by a factor(s) associated with cellular inflammation.
