    Abstract The relevance of innate lymphoid cells (ILC) for anti-infectious immunity remains a matter of constant debate. At the same time, evidence for additional, non-immune related functions of ILC is steadily increasing. In the thymus, non-immune functions of ILC were shown for group 3 ILC (ILC3), which regulate differentiation and proliferation of thymic epithelial cells. In this issue of the European Journal of Immunology, Withers and colleagues [Eur. J. Immunol. 2018. 48: 1481-1491] now show that ILC2, a subset of ILCs specialized in tissue protection and regeneration, are the major ILC subset in the adult thymus, heavily outnumbering ILC3. These findings raise novel questions on the function of thymic ILC, and warrant re-evaluation of the importance of ILC2 and their cytokines during thymic function and repair.

    Abstract Tissue inflammation is a hallmark of tumour microenvironments. In the bone marrow, tumour-associated inflammation impacts normal niches for haematopoietic progenitor cells and mature immune cells and supports the outgrowth and survival of malignant cells residing in these niche compartments. This Review provides an overview of our current understanding of inflammatory changes in the bone marrow microenvironment of myeloid and lymphoid malignancies, using acute myeloid leukaemia and multiple myeloma as examples and highlights unique and shared features of inflammation in niches for progenitor cells and plasma cells. Importantly, inflammation exerts profoundly different effects on normal bone marrow niches in these malignancies, and we provide context for possible drivers of these divergent effects. We explore the role of tumour cells in inflammatory changes, as well as the role of cellular constituents of normal bone marrow niches, including myeloid cells and stromal cells. Integrating knowledge of disease-specific dynamics of malignancy-associated bone marrow inflammation will provide a necessary framework for future targeting of these processes to improve patient outcome.

    Abstract n this issue of Blood, Hazenberg and Spits provide a detailed overview of human innate lymphoid cell (ILC) subsets and their development and distribution throughout the human body, discussing these cells in the context of human disease. In the same issue, Munneke et al for the first time link ILCs to human hematopoietic malignancies by identifying a clear correlation between the presence of activated ILCs after induction chemotherapy and the absence of acute graft-versus-host disease (GVHD) development following subsequent hematopoietic stem cell transplantation (HSCT).

    Abstract In the developing human fetus, lymph nodes and Peyer's patches are formed during the first and second trimester of pregnancy. The cells responsible for this process, lymphoid tissue inducer (LTi) cells, share a number of characteristics with Natural Killer (NK) cells and produce cytokines related to inflammation. Here I will discuss recent advances in our understanding of human lymph node development, in particular the characterization of LTi cells and the relationship of these innate lymphocytes to conventional NK cells.

    Abstract Purpose of review: Innate lymphoid cells (ILC) have emerged as modulators of conditioning-induced tissue damage and development of graft-versus-host disease (GVHD) in the context of allogeneic hematopoietic stem cell transplantation (HSCT). This review highlights experimental and clinical evidence for a role of ILC in GVHD pathogenesis.
    Recent findings: ILC are well known for their role in epithelial homeostasis and innate immunity. In addition, recent studies identified ILC as architects of intestinal responses to tissue damage after experimental radio and chemotherapy. Group 3 ILC, and their signature cytokine IL-22, can enhance intestinal stem cell regeneration and protect the stem cell niche from damage during experimental HSCT. Moreover, in leukemia patients undergoing HSCT conditioning, appearance of activated group 3 ILC prior to transplant is correlated to reduced incidence of acute GVHD.
    Summary: ILC have a profound impact on the recovery from tissue damage and severity of GVHD in experimental models. Together with the available data from leukemia patients, this argues for in-depth analysis of the mechanisms of ILC function and the translation of experimental findings to clinical application. Ultimately, control of ILC activation, or of the cytokines they produce, could be employed to reduce GVHD lesion in patients receiving allogeneic HSCT.

    Abstract Human bone marrow permanently harbors high numbers of neutrophils, and a tumor-supportive bias of these cells could significantly impact bone marrow-confined malignancies. In individuals with multiple myeloma, the bone marrow is characterized by inflammatory stromal cells with the potential to influence neutrophils. We investigated myeloma-associated alterations in human marrow neutrophils and the impact of stromal inflammation on neutrophil function. Mature neutrophils in myeloma marrow are activated and tumor supportive and transcribe increased levels of IL1B and myeloma cell survival factor TNFSF13B (BAFF). Interactions with inflammatory stromal cells induce neutrophil activation, including BAFF secretion, in a STAT3-dependent manner, and once activated, neutrophils gain the ability to reciprocally induce stromal activation. After first-line myeloid-depleting antimyeloma treatment, human bone marrow retains residual stromal inflammation, and newly formed neutrophils are reactivated. Combined, we identify a neutrophil-stromal cell feed-forward loop driving tumor-supportive inflammation that persists after treatment and warrants novel strategies to target both stromal and immune microenvironments in multiple myeloma.

    Abstract Innate lymphoid cells (ILCs) are immune cells that lack a specific antigen receptor yet can produce an array of effector cytokines that in variety match that of T helper cell subsets. ILCs function in lymphoid organogenesis, tissue remodeling, antimicrobial immunity, and inflammation, particularly at barrier surfaces. Their ability to promptly respond to insults inflicted by stress-causing microbes strongly suggests that ILCs are critical in first-line immunological defenses. Here, we review current data on developmental requirements, lineage relationships, and effector functions of two families of ILCs: (a) Rorγt-expressing cells involved in lymphoid tissue formation, mucosal immunity, and inflammation and (b) type 2 ILCs that are important for helminth immunity. We also discuss the potential roles of ILCs in the pathology of immune-mediated inflammatory and infectious diseases including allergy.
