The cellular interactions involved in maintaining CD4+ T-cell memory have hitherto not been identified. In this report, we have investigated the role played by B cells in this process. We show that that long-lasting helper T-cell memory depends on the presence of B cells, but that direct antigen presentation by B cells is not required. These findings provide new insights into the mechanisms which underlie helper T-cell memory. They also suggest that the efficacy of future vaccines will depend critically on the inclusion of B- as well as T-cell epitopes.
迄今为止,维持CD4+ T细胞记忆所涉及的细胞间相互作用尚未明确。在本报告中,我们研究了B细胞在此过程中所起的作用。我们发现,持久的辅助性T细胞记忆依赖于B细胞的存在,但并不需要B细胞直接呈递抗原。这些发现为辅助性T细胞记忆的潜在机制提供了新的见解。它们还表明,未来疫苗的效力将严重依赖于同时包含B细胞表位和T细胞表位。
