Abstract
Type 1 diabetes (T1D) arises from autoimmune-mediated destruction of insulin-producing pancreatic beta cells. Recent advancements in the technology of generating pancreatic beta cells from human pluripotent stem cells (SC-beta cells) have facilitated the exploration of cell replacement therapies for treating T1D. However, the persistent threat of autoimmunity poses a significant challenge to the survival of transplanted SC-beta cells. Genetic engineering is a promising approach to enhance immune resistance of beta cells as we previously showed by inactivating the Renalase (Rnls) gene. Here, we demonstrate that Rnls loss of function in beta cells shapes autoimmunity by mediating a regulatory natural killer (NK) cell phenotype important for the induction of tolerogenic antigen-presenting cells. Rnls-deficient beta cells mediate cell-cell contact-independent induction of hallmark anti-inflammatory cytokine Tgfβ1 in NK cells. In addition, surface expression of regulatory NK immune checkpoints CD47 and Ceacam1 is markedly elevated on beta cells deficient for Rnls. Altered glucose metabolism in Rnls mutant beta cells is involved in the upregulation of CD47 surface expression. These findings are crucial to better understand how genetically engineered beta cells shape autoimmunity, giving valuable insights for future therapeutic advancements to treat and cure T1D.

Abstract
The Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), also known as CD66a, is a member of the immunoglobulin superfamily. CEACAM1 was shown to be a prognostic marker in patients suffering from cancer. In this review, we summarize pre-clinical and clinical evidence linking CEACAM1 to tumorigenicity and cancer progression. Furthermore, we discuss potential CEACAM1-based mechanisms that may affect cancer biology.

Abstract
Quantitative differences in signal transduction are to date an understudied feature of tumour heterogeneity. The MAPK Erk pathway, which is activated in a large proportion of human tumours, is a prototypic example of distinct cell fates being driven by signal intensity. We have used primary hepatocyte precursors transformed with different dosages of an oncogenic form of Ras to model subclonal variations in MAPK signalling. Orthotopic allografts of Ras-transformed cells in immunocompromised mice gave rise to fast-growing aggressive tumours, both at the primary location and in the peritoneal cavity. Fluorescent labelling of cells expressing different oncogene levels, and consequently varying levels of MAPK Erk activation, highlighted the selection processes operating at the two sites of tumour growth. Indeed, significantly higher Ras expression was observed in primary as compared to secondary, metastatic sites, despite the apparent evolutionary trade-off of increased apoptotic death in the liver that correlated with high Ras dosage. Analysis of the immune tumour microenvironment at the two locations suggests that fast peritoneal tumour growth in the immunocompromised setting is abrogated in immunocompetent animals due to efficient antigen presentation by peritoneal dendritic cells. Furthermore, our data indicate that, in contrast to the metastatic-like outgrowth, strong MAPK signalling is required in the primary liver tumours to resist elimination by NK (natural killer) cells. Overall, this study describes a quantitative aspect of tumour heterogeneity and points to a potential vulnerability of a subtype of hepatocellular carcinoma as a function of MAPK Erk signalling intensity.

CEACAM-1 Induced CSF3-receptor Downregulation in Bone Marrow Associated With Refractory Neutropenia in Advanced Cirrhosis. J Clin Transl Hepatol 2022; 10:53-62. [PMID: 35233373 PMCID: PMC8845158 DOI: 10.14218/jcth.2021.00331] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 10/07/2021] [Accepted: 10/20/2021] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND AND AIMS Cirrhosis patients exhibit cytopenia, and, at times refractory neutropenia to granulocyte colony-stimulating factor (G-CSF), which acts through the CSF3-receptor (CSF3R), and changes in CSF3R can affect the response. We conducted this study to assess the CSF3R status and its relevance in cirrhotic patients. METHODS Cirrhotic patients (n=127) and controls (n=26) with clinically indicated bone marrow (BM) examination were studied. BM assessment was done by qRT-PCR and immunohistochemistry (IHC) for CSF3R. Circulating G-CSF, CSF3R, and carcinoembryonic antigen cell adhesion molecule-1 (CEACAM1) were measured. BM hematopoietic precursor cells and their alterations were examined by flow cytometry. The findings were validated in liver cirrhosis patients who received G-CSF for severe neutropenia. RESULTS The mean age was 48.6±13.4 years, and 80.3% were men. Circulatory CSF3R reduction was noted with the advancement of cirrhosis, and confirmed by qRT-PCR and IHC in BM. CSF3R decline was related to decreased hematopoietic stem cells (HSCs) and downregulation of CSF3R in the remaining HSCs. Cocultures confirmed that CEACAM1 led to CSF3R downregulation in BM cells by possible lysosomal degradation. Baseline low peripheral blood-(PB)-CSF3R also predisposed development of infections on follow-up. Decreased CSF3R was also associated with nonresponse to exogenous G-CSF treatment of neutropenia. CONCLUSIONS Advanced liver cirrhosis was associated with low CSF3R and high CEACAM1 levels in the BM and circulation, making patients prone to infection and inadequate response to exogenous G-CSF.

Down-regulation of HLA-B-associated transcript 3 impairs the tumoricidal effect of natural killer cells through promoting the T cell immunoglobulin and mucin domain-containing-3 signaling in a mouse head and neck squamous cell carcinoma model. Immunobiology 2021; 227:152127. [PMID: 34968777 DOI: 10.1016/j.imbio.2021.152127] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 07/09/2021] [Accepted: 07/25/2021] [Indexed: 11/22/2022]
Abstract
Head and neck squamous cell carcinoma (HNSCC) arises from the malignant mucosal epithelium of the oral cavity, pharynx, and larynx. Natural killer (NK) cells are fundamental immune cells shaping the anti-HNSCC response. Elucidation of the regulatory mechanisms of NK cell activity is crucial for understanding anti-HNSCC immunity. In this study, we characterized the expression and function of HLA-B-associated transcript 3 (Bat3) in NK cells in a mouse HNSCC model. We found that Bat3 expression was down-regulated in HNSCC-infiltrating NK cells. SCC VII, the mouse HNSCC cell line used in this model, induced Bat3 downregulation through direct cell-to-cell contact. By applying lentivirus-mediated silencing of Bat3, we discovered that Bat3 knockdown impaired the tumoricidal effect of NK cells on SCC VII cells and Hepa1-6RAE1, a genetically modified liver cancer cell line. Furthermore, Bat3 knockdown resulted in a significant decrease in perforin, granzyme B, interferon-γ, and tumor necrosis factor-α in NK cells upon co-culture with SCC VII cells. Further investigations revealed that Bat3 knockdown promoted the binding of T cell immunoglobulin and mucin domain-containing-3 (Tim-3) to Fyn and thus activated the Tim-3 signaling. Blockade of Tim-3 with a neutralizing Tim-3 antibody counteracted the effect of Bat3 knockdown on NK cell cytotoxicity. Taken together, our data suggest that HNSCC might down-regulate Bat3 expression to augment Tim-3 signaling and ultimately suppress the tumoricidal activity of NK cells. This study unveils a novel mechanism by which HNSCC evades NK cell killing, and sheds light on designing novel anti-HNSCC immunotherapy targeting Bat3 and Tim-3 signaling.

Abstract
Background Natural killer (NK) cells can recognize and kill cancer cells directly, but their activity can be attenuated by various inhibitory molecules expressed on the surface. The expression of epithelial cell adhesion molecule (EpCAM), a potential marker for cancer stem cells (CSCs), is known to be strongly associated with poor clinical outcomes in hepatocellular carcinoma (HCC). NK cells targeting CSCs may be a promising strategy for anti-tumor therapy, but little is known about how they respond to EpCAMhigh CSCs in HCC. Methods EpCAM expression was assessed by immunohistochemistry in 280 human HCC tissues obtained from curative surgery. To investigate the functional activity of NK cells against liver CSCs, EpCAMhigh and EpCAMlow Huh-7 cells were sorted by flow cytometry. The functional role of carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), which is related to NK cells, was determined by in vitro co-culture of NK cells and hepatoma cells using Hepa1–6 mouse hepatoma cells, as well as in vivo experiments using C57/BL6 mice. Results The frequency of recurrence after curative surgery was higher in patients with positive EpCAM expression than in those with negative EpCAM expression. In subsequent analysis based on the anatomical location of EpCAM expression, patients with peritumoral EpCAM expression showed worse prognosis than those with pantumoral EpCAM expression. Co-culture experiments demonstrated that CEACAM1 was upregulated on the surface of EpCAMhigh HCC cells, resulting in resistance to NK cell-mediated cytotoxicity. Inversely, silencing CEACAM1 restored cytotoxicity of NK cells against EpCAMhigh Huh-7 cells. Moreover, neutralizing CEACAM1 on the NK cell surface enhanced killing of Huh-7 cells, suggesting that homophilic interaction of CEACAM1 is responsible for attenuated NK cell–mediated killing of CEACAM1high cells. In mouse experiments with Hepa1–6 cells, EpCAMhigh Hepa1–6 cells formed larger tumors and showed higher CEACAM1 expression after NK cell depletion. NK-mediated cytotoxicity was enhanced after blocking CEACAM1 expression using the anti-CEACAM1 antibody, thereby facilitating tumor regression. Moreover, CEACAM1 expression positively correlated with EpCAM expression in human HCC tissues, and serum CEACAM1 levels were also significantly higher in patients with EpCAM+ HCC. Conclusion Our data demonstrated that EpCAMhigh liver CSCs resist NK cell–mediated cytotoxicity by upregulation of CEACAM1 expression.

Abstract
Recently, impacts of microRNAs have been unraveled in human diseases, and we aimed to confirm the role of miR-30b/30d in fulminant hepatic failure (FHF). Expression of miR-30b/30d and CEACAM1 in serum of FHF patients and healthy people was measured by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western blot analysis. Mice FHF models were established by injection of D-Galn and lipopolysaccharide, and were treated with miR-30b/30d mimics. Oxidative stress, liver injury, and inflammatory reaction in mouse liver tissues were measured using oxidative stress-related factor kits, hematoxylin-eosin staining and enzyme-linked immunosorbent assay, respectively. Moreover, cell cycle distribution and apoptosis of hepatocytes of mice were determined by flow cytometry, and the target relation between miR-30b/30d and CEACAM1 was confirmed by bioinformatic method and dual luciferase reporter gene assay. MiR-30b/30d expression was positively, and CEACAM1 expression was negatively related to prognosis of FHF patients. Up-regulation of miR-30b/30d attenuated oxidative stress, liver injury, and inflammatory reaction, and improved survival rate of FHF mice. Furthermore, elevated miR-30b/30d ameliorated apoptosis and cell cycle arrest of hepatocytes of FHF mice. CEACAM1 was a target gene of miR-30b/30d. This study highlights that up-regulated miR-30b/30d attenuates the progression of FHF by targeting CEACAM1, which may be helpful to FHF treatment.

Abstract
Viruses and natural killer (NK) cells have a long co-evolutionary history, evidenced by patterns of specific NK gene frequencies in those susceptible or resistant to infections. The killer immunoglobulin-like receptors (KIR) and their human leukocyte antigen (HLA) ligands together form the most polymorphic receptor-ligand partnership in the human genome and govern the process of NK cell education. The KIR and HLA genes segregate independently, thus creating an array of reactive potentials within and between the NK cell repertoires of individuals. In this review, we discuss the interplay between NK cell education and adaptation with virus infection, with a special focus on three viruses for which the NK cell response is often studied: human immunodeficiency virus (HIV), hepatitis C virus (HCV) and human cytomegalovirus (HCMV). Through this lens, we highlight the complex co-evolution of viruses and NK cells, and their impact on viral control.
