Social interactions profoundly influence animals' life. The quality of social interactions and many everyday life decisions are determined by a proper perception, processing and reaction to others' emotions. Notably, alterations in these social processes characterize a number of neurodevelopmental disorders, including autism spectrum disorders and schizophrenia. Increasing evidences support an implication of immune system vulnerability and inflammatory processes in disparate behavioral functions and the aforementioned neurodevelopmental disorders. In this review, we show a possible unifying view on how immune responses, within and outside the brain, and the communication between the immune system and brain responses might influence emotion recognition and related social responses. In particular, we highlight the importance of combining genetics, immunology and microbiology factors in understanding social behaviors. We underline the importance of better disentangling the whole machinery between brain-immune system interactions to better address the complexity of social processes.

免疫学和微生物学：它们如何影响社会认知和情感识别？

社会互动深刻地影响着动物的生活。社交互动和许多日常生活决定的质量取决于对他人情绪的正确感知、处理和反应。值得注意的是，这些社会过程的改变是许多神经发育障碍的特征，包括自闭症谱系障碍和精神分裂症。越来越多的证据支持免疫系统脆弱性和炎症过程在不同的行为功能和上述神经发育障碍中的影响。在这篇综述中，我们展示了一个可能的统一观点，即大脑内外的免疫反应，以及免疫系统和大脑反应之间的交流如何影响情绪识别和相关的社会反应。特别是，我们强调结合遗传学、免疫学和微生物学因素在理解社会行为方面的重要性。我们强调了更好地解开脑免疫系统相互作用之间的整个机制以更好地解决社会过程的复杂性的重要性。
