2022 年 5 月在非流行国家确认的猴痘病毒 (MPXV) 爆发引起了人们对新型正痘病毒大流行潜力的担忧。关于 MPXV 感染或接种痘苗疫苗 (VACV) 情况下的 MPXV 免疫力,人们知之甚少。与牛痘一样,T 细胞可能对 MPXV 的整体免疫力做出重要贡献。在这里,我们利用 VACV 免疫表位数据库 (IEDB) 中提供的表位信息来预测 CD4+ 和 CD8+ T 细胞反应识别的潜在 MPXV 靶点。我们发现 VACV 表位和 MPXV 之间存在高度保守性,并确定了 T 细胞免疫显性靶标。这些分析使得肽池的设计能够通过实验检测一组接种疫苗的个体中的 VACV 特异性 T 细胞反应和 MPXV 交叉反应 T 细胞。我们的研究结果将有助于监测 MPXV 感染和疫苗接种后的细胞免疫。格里福尼等人。开发了正痘和猴痘特异性表位库来测量自然感染和疫苗接种中猴痘 T 细胞的反应。通过检测 Dryvax 疫苗接种者的 PBMC 中的记忆 T 细胞反应来验证这些池。大多数 Dryvax 疫苗 CD4 反应具有细胞毒性并产生颗粒酶 B。
The monkeypox virus (MPXV) outbreak confirmed in May 2022 in non-endemic countries is raising concern about the pandemic potential of novel orthopoxviruses. Little is known regarding MPXV immunity in the context of MPXV infection or vaccination with vaccinia-based vaccines (VACV). As with vaccinia, T cells are likely to provide an important contribution to overall immunity to MPXV. Here, we leveraged the epitope information available in the Immune Epitope Database (IEDB) on VACV to predict potential MPXV targets recognized by CD4+ and CD8+ T cell responses. We found a high degree of conservation between VACV epitopes and MPXV and defined T cell immunodominant targets. These analyses enabled the design of peptide pools able to experimentally detect VACV-specific T cell responses and MPXV cross-reactive T cells in a cohort of vaccinated individuals. Our findings will facilitate the monitoring of cellular immunity following MPXV infection and vaccination. Grifoni et al. developed orthopox- and monkeypox-specific epitope pools to measure monkeypox T cell responses in natural infection and vaccination. The pools were validated by detection of memory T cell responses in PBMCs from Dryvax vaccinees. A majority of the Dryvax-vaccinee CD4 responses were cytotoxic and produced granzyme B.
