title: Shades of grey--the blurring view of innate and adaptive immunity.
abstract: This special issue of Nature Reviews Immunology focuses on the types of lymphocyte that blur the traditional boundaries between the innate and adaptive immune systems. The development and functional properties of 'innate-like' B and T cells and natural killer (NK) cells are reviewed and the emerging understanding of newly discovered innate lymphoid cells (ILCs) is considered.
