The microbiota is emerging as a fundamental contributor to the metabolic health of the host, and its interplay with the immune system is increasingly being investigated (Zheng et al. 2020). It is therefore not surprising that many behavioral ecologists studying MHC-related odors have recently brought up to date the potential role of microbiota in MHC-related odor production, a hypothesis stated several decades ago (Singh et al. 1990) but rarely tested. The review of Schubert et al. (2021) is therefore very timely.

深入研究 MHC 相关的气味：对 Schubert 等人的评论。

微生物群正在成为宿主代谢健康的基本贡献者，并且越来越多地研究其与免疫系统的相互作用（Zheng 等人，2020 年）。因此，许多研究 MHC 相关气味的行为生态学家最近提出了微生物群在 MHC 相关气味产生中的潜在作用也就不足为奇了，这是几十年前提出的假设（Singh 等人，1990 年），但很少得到验证。舒伯特等人的评论。(2021) 因此非常及时。
