About this Research Topic
Innate Lymphoid Cells (ILCs) are an emerging category of tissue- resident immune players, which are key in maintaining mucosal homeostasis. ILCs contribute to preserve the delicate equilibrium between the host and the numerous commensals that cohabitate with the host; they also participate in shaping appropriate immune response to invading pathogens at mucosal barriers. Emerging evidence indicates that ILCs continuously integrate stimuli coming from the surrounding environment, such as dietary products and metabolites, and stimuli coming from the hosts, including cytokines and neurotrophic factors. ILCs also seed non-mucosal tissues, such as adipose tissue and secondary lymphoid organs, where they contribute to regulation of metabolic processes, to lymphoid organogenesis and wound healing. In this Topic of Frontiers in Immunology experts in the field will review aspects of:
- ILC diversity and functional polarization;
- ILC development;
- ILC function in health and disease;
- Redundancy between ILCs and T cells;
- ILC plasticity;
- Similarities and differences between “old” and “new” ILCs.
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
