    Abstract: Tuberculosis (TB), which is a frequent and important infectious disease caused by Mycobacterium tuberculosis , has resulted in an extremely high burden of morbidity and mortality. The importance of intestinal dysbacteriosis in regulating host immunity has been implicated in TB, and accumulating evidence suggests that microRNAs (miRNAs) might act as a key mediator in maintaining intestinal homeostasis through signaling networks. However, the involvement of miRNA in gut microbiota, TB and the host immune system remains unknown. Here we showed that intestinal dysbacteriosis increases the susceptibility to TB and remotely increased the expression of miR-21 in lung. Systemic antagonism of miR-21 enhanced IFN-γ production and further conferred immune protection against TB. Molecular experiments further indicated that miR-21a-3p could specifically target IFN-γ mRNA. These findings revealed regulatory pathways implicating intestinal dysbacteriosis induced-susceptibility to TB: intestinal dysbiosis→lung miRNA→targeting IFN-γ→impaired anti-TB immunity. This study also suggested that deregulated miRNAs by commensal bacteria could become promising targets as TB therapeutics.

    Abstract: Infection and nutrition are intricately interacted and further influence human health. Infections are a worldwide health problem and malnutrition plays a significant role in the emergence of infection. Growing evidence suggests that the optimization of dietary nutrients intake is crucial in maintaining systemic immunity and may help improve resistance to infections. In this review, we explore a wide range of topics including interactions between nutrients and various infectious diseases. We also discuss the role of diet-induced gut microbiota in the infection-nutrition cycle and review how dietary-microbiome crosstalk may affect disease development and progression, which may provide an attractive option to the design of a diet leading to favorable outcomes in the future. We will also present evidence and propose mechanisms of nutrients that may specifically modulate host immunity and metabolism to infectious pathogens and also cover its influence on nutrition, focusing on immuno-nutrients. We provide representative nutrients in the present review based on their intensive studies and wide acceptance of their immuno-modulating properties. Moreover, the efficacy and translational cost of their plausible utility to be anti-infective nutrients are also reviewed. Finally, we highlight the current progress and challenges to gain a better understanding of the research into microbiota, infectious diseases, and nutrition with an emphasis on future research directions.
