Abstract

Mice depleted of lymphocytes expressing the alpha beta or the gamma delta T-cell receptor for antigen (TCR) by antibody treatment were infected orally with Salmonella enteritidis. In both groups of treated mice, the 50% lethal dose decreased, suggesting that both the alpha beta TCR+ and the gamma delta TCR+ subsets contribute to resistance to oral infection. These data provide further evidence for the contribution of gamma delta T cells in the response to bacterial infections.

摘要

通过抗体处理使表达抗原αβ或γδ T细胞受体(TCR)的淋巴细胞耗竭的小鼠经口感染肠炎沙门氏菌。在两组经处理的小鼠中,50%致死剂量均降低,这表明αβ TCR+和γδ TCR+亚群均有助于抵抗经口感染。这些数据为γδ T细胞在细菌感染应答中的作用提供了进一步的证据。
