Abstract
Type 2 innate lymphoid cells (ILC2s) are important producers of type 2 cytokines whose role in hematological cancers remains unclear. ILC2s are a heterogeneous population encompassing distinct subsets with different tissue localization and cytokine responsiveness. In this study, we investigated the role of bone marrow (BM) ILC2s and interleukin (IL)-33-stimulated ILC2s in multiple myeloma, a plasma cell malignancy that develops in the BM. We found that myeloma growth was associated with phenotypic and functional alterations of BM ILC2s, characterized by an increased expression of maturation markers and reduced cytokine response to IL-2/IL-33. We identified a population of KLRG1hi ILC2s that ..
