Resident microorganisms, known as the microbiota, are essential for many physiological functions
including protection against pathogens. Microbiota is indeed required for proper immune system
development and function, and can also host-independently protect against infections. Thus, a coconstructed view of host defense involving both host and microbiota, named “co-immunity”, has been
proposed, and the idea of an “immunological holobiont” has been suggested. Yet this view of coimmunity might be too limited, as experimental work has shown that the immune system is involved
in functions other than defense, essentially development and repair. Microbiota, through coimmunity, is thereby most likely involved in these functions, although strong evidence is currently
lacking. Moreover, as our point of view is mainly host-centered, we may miss the implications of coimmunity at broaderscales, including cellular and populational levels. Intriguingly, co-immunity effects
could be beneficial for one function and/or one level, while detrimental for others. All these elements
should be taken into consideration for microbiota manipulation, in order to avoid potentially harmful
side effects.
