Innate lymphoid cells (ILCs) represent a diverse family of cells of the innate immune system, which play an important role in regulation of tissue homeostasis, immunity and inflammation. Emerging evidence has highlighted the importance of ILCs in both protective immunity to respiratory infections and their pathological roles in the lungs. Therefore, the aim of this review is to summarize the current knowledge, interpret and integrate it into broader perspective, enabling greater insight into the role of ILCs in respiratory diseases...

The transcription factor T-bet has been associated with increased susceptibility to systemic and organ-specific autoimmunity, but the mechanism by which T-bet expression promotes neuroinflammation remains unknown. In this study, we demonstrate a cardinal role of T-bet-dependent NKp46(+) innate lymphoid cells (ILCs) in the initiation of CD4(+) TH17-mediated neuroinflammation. Loss of T-bet specifically in NKp46(+) ILCs profoundly impaired the ability of myelin-reactive TH17 cells to invade central nervous system (CNS) tissue and protected the mice from autoimmunity...

REVIEW
Hui Peng, Zhigang Tian
Although natural killer (NK) cells were initially named for their spontaneous tumor-killing capacity, their concept has been greatly expanded with more than 40 years of extensive investigation. Currently, NK cells are known as a heterogeneous population of innate lymphoid cell (ILC) family, consisting of different subsets with unique phenotypic and functional features. Recent studies have shown that tissue-resident NK (trNK) cells, which are distinct from conventional NK (cNK) cells, preferentially distribute in non-lymphoid tissues, such as the liver, uterus, salivary gland, and adipose...

OBJECTIVES: The aim of this study was to describe the procedural aspects and outcomes of retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) through ipsilateral collateral channels (ILCs). BACKGROUND: Retrograde CTO PCI via ILCs is rarely performed, usually when no other retrograde options exist, and available evidence derives mostly from case reports. METHODS: A large retrospective multinational registry was compiled, including all consecutive patients undergoing retrograde CTO PCI through ILCs at 6 centers between September 2011 and October 2016...

Group 3 innate lymphoid cells (ILC3) promote lymphoid organogenesis and potentiate immune responses against bacterial infection. However, how ILC3 cells are developed and maintained is still unclear. Here, we show that carboxypeptidase CCP2 is highly expressed in common helper-like innate lymphoid progenitors, the progenitor of innate lymphoid cells, and CCP2 deficiency increases ILC3 numbers. Interleukin-7 receptor subunit alpha (IL-7Rα) is identified as a substrate of CCP2 for deglutamylation, and IL-7Rα polyglutamylation is catalyzed by polyglutamylases TTLL4 and TTLL13 in common helper-like innate lymphoid progenitors...

Fibrosis is the result of dysregulated tissue regeneration and is characterized by excessive accumulation of matrix proteins that become detrimental to tissue function. In Crohn's disease, this manifests itself as recurrent gastrointestinal strictures for which there is no effective therapy beyond surgical intervention. Using a model of infection-induced chronic gut inflammation, we show that Rora-deficient mice are protected from fibrosis; infected intestinal tissues display diminished pathology, attenuated collagen deposition, and reduced fibroblast accumulation...

Innate lymphoid cells (ILCs) play a central role conferring protection at the mucosal frontier. In this study, we have identified a requirement of the transcription factor Zbtb1 for the development of RORγt+ ILCs (ILC3s). Zbtb1-deficient mice lacked NKp46+ ILC3 cells in the lamina propria of the small and large intestine. This requirement of Zbtb1 was cell intrinsic, as NKp46+ ILC3s were not generated from Zbtb1-deficient progenitors in bone marrow chimeras and Zbtb1-deficient RORγt+ CCR6-NKp46- ILC3s didn't generate NKp46+ ILC3s in co-cultures with OP9-DL1 stroma...

To investigate the clinicopathological characteristics and to determine whether there is a differential effect of race and examine survival outcomes according to race, 18,295 breast invasive lobular carcinoma (ILC) patients were identified in the Surveillance, Epidemiology, and End Result (SEER) database, which includes White patients (n=15,936), Black patients (n=1,451) and patients of other races (including American Indians/Alaskan Natives and Asian/Pacific Islanders) (n=908). The Black ILC patients presented a higher rate of advanced histological grades and American Joint Committee on Cancer (AJCC) stages, a higher rate of lymph node (LN) involvement and a lower rate of progesterone receptors (PR)-positivity than the White patients and other races...

Avoiding destruction by immune cells is a hallmark of cancer, yet how tumors ultimately evade control by natural killer (NK) cells remains incompletely defined. Using global transcriptomic and flow-cytometry analyses and genetically engineered mouse models, we identified the cytokine-TGF-β-signaling-dependent conversion of NK cells (CD49a(-)CD49b(+)Eomes(+)) into intermediate type 1 innate lymphoid cell (intILC1) (CD49a(+)CD49b(+)Eomes(+)) populations and ILC1 (CD49a(+)CD49b(-)Eomes(int)) populations in the tumor microenvironment...

BACKGROUND: Invasive lobular carcinoma (ILC) comprises around 10 - 15% of invasive breast cancers. Few prior studies have demonstrated a unique pattern of metastases between ILC and the more common invasive ductal carcinoma (IDC). To our knowledge, such data is limited to first sites of distant recurrence. We aimed to perform a comparison of the metastatic pattern of ILC and IDC at first distant recurrence as well as over the entire course of metastatic disease. METHODS: We used a prospectively collated database of patients with metastatic breast cancer...

PURPOSE: Invasive micropapillary carcinoma (IMPC) of the breast has distinct histological features and molecular genetic profiles. Gains/amplifications of 8q24 are found associated with IMPC. Although the prostate stem cell antigen (PSCA) gene is located at chromosome 8q24, and found over-expressed in prior studies, its prognostic values and biological significance in IMPC have not been well studied. METHODS: Fluorescence in situ hybridization (FISH) was used to assess the frequencies of PSCA copy number gains in IMPC, invasive ductal carcinoma of no special type (IDC-NST), and invasive lobular carcinoma (ILC) samples...

Endoplasmic reticulum (ER) stress is commonly observed in intestinal epithelial cells (IECs) and can, if excessive, cause spontaneous intestinal inflammation as shown by mice with IEC-specific deletion of X-box-binding protein 1 (Xbp1), an unfolded protein response-related transcription factor. In this study, Xbp1 deletion in the epithelium (Xbp1(ΔIEC) ) is shown to cause increased expression of natural killer group 2 member D (NKG2D) ligand (NKG2DL) mouse UL16-binding protein (ULBP)-like transcript 1 and its human orthologue cytomegalovirus ULBP via ER stress-related transcription factor C/EBP homology protein...

BACKGROUND: Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) are predominant and well-documented types of invasive breast cancers (IBC). However, clinical outcomes of other types of IBC (i.e., uncommon IBC), which collectively account for about 20% of all IBC cases, are largely unknown. METHODS: We identified all IBC cases diagnosed in 2004-2006 (n=159,293) and 2010-2011 (n=118,822) from the Surveillance, Epidemiology and End Results (SEER) database...

BACKGROUND: Pathogenesis of atopic dermatitis (AD) involves interaction between type 2 cells that include basophils, mast cells, innate lymphoid type 2 cells (ILC2), and Th2 cells. Levels of IL-4 and IL-13 are elevated in AD patients. OBJECTIVE: Here, we investigated the distribution of type 2 cells and the source of IL-4 and IL-13 in skin and blood of AD relative to psoriasis. METHODS: Lesional skin biopsies and blood were collected from patients...

Innate lymphoid cells (ILCs) are newly identified innate lymphocytes in humans and mice that are important and effective cells of innate immunity and regulate adaptive immunity. ILCs have been found to promote the start, regulation and resolution of inflammation. ILCs play an important role in the progress of infection, inflammation and tissue repair in the mouse model, and clinic researches also indicate the importance of ILCs in human health and disease. Based on the previous related researches, the types of ILCs and the role of these populations in promoting acute and chronic inflammation as well as resolution inflammation and tissue repair were mainly reviewed to provide new insights for the further study...

CONTEXT: Indigofera suffruticosa Miller (Fabaceae) and I. truxillensis Kunth produce compounds, such as isatin (ISA) and indirubin (IRN), which possess antitumour properties. Their effects in mammalian cells are still not very well understood. OBJECTIVE: We evaluated the activities of ISA and/or IRN on cell viability and apoptosis in vitro, their genotoxic potentials in vitro and in vivo, and the IRN- and ISA-induced expression of ERCC1 or BAX genes. MATERIALS AND METHODS: HeLa and/or CHO-K1 cell lines were tested (3 or 24 h) in the MTT, Trypan blue exclusion, acridine orange/ethidium bromide, cytokinesis-blocked micronucleus (CBMN) and comet (36, 24 and 72 h) tests after treatment with IRN (0...

T cell homeostasis critically depends on interleukin-7 (IL-7). In this issue of Immunity, Martin et al. (2017) provide evidence that IL-7 availability is regulated through a "cytokine sink" involving innate lymphoid cells that compete for and consume IL-7 and thereby restrict T cell homeostasis in lymphoid organs.

BACKGROUND: Invasive pleomorphic lobular carcinoma (IPLC) has been associated with a worse prognosis compared with classic invasive lobular carcinoma (cILC); however, studies are small and conflicting. We seek to examine the prognosis of women with IPLC compared with cILC. METHODS: A retrospective review of women with breast cancer at a single institution from 2003 to 2012 identified 193 women with invasive lobular carcinoma (ILC). IPLC was defined as ILC with a pathological description of primarily pleomorphic features and Nottingham histological grade score of 7, 8, or 9 or overall grade of 3 or mixed classic/pleomorphic features and overall grade of 3...

Recent studies identified an emerging role of group 2 and 3 innate lymphoid cells (ILCs) as key players in the generation of T-dependent and T-independent antibody production. In this retrospective case-control study CD117(+) ILCs (including the majority of ILC2 and ILC3) were reduced in patients with common variable immunodeficiency (CVID). The reduction in CD117(+) ILCs was distinctive to CVID and could not be observed in patients with X linked agammaglobulinemia (XLA). Patients with a more pronounced reduction in CD117(+) ILC numbers showed significantly lower numbers of peripheral MZ-like B cells and an increased prevalence of chronic, non-infectious enteropathy...
