Abstract
BACKGROUND IgG4-related disease (IgG4-RD), an example of a type I immune disease, is an immune-mediated fibrotic disorder characterized by dysregulated resolution of severe inflammation and wound healing. However, truly dominant or pathognomonic autoantibodies related to IgG4-RD are not identified. OBJECTIVE We sought to perform single-cell RNA sequencing and T-cell receptor and B-cell receptor sequencing to obtain a comprehensive, unbiased view of tissue-infiltrating T and B cells. METHODS We performed unbiased single-cell RNA-sequencing analysis for the transcriptome and T-cell receptor sequencing and B-cell receptor sequencing on sorted CD3+ T or CD19+ B cells from affected tissues of patients with IgG4-RD. We also conducted quantitative analyses of CD3+ T-cell and CD19+ B-cell subsets in 68 patients with IgG4-RD and 30 patients with Sjögren syndrome. RESULTS Almost all clonally expanded T cells in these lesions were either Granzyme K (GZMK)-expressing CD4+ cytotoxic T cells or GZMK+CD8+ T cells. These GZMK-expressing cytotoxic T cells also expressed amphiregulin and TGF-β but did not express immune checkpoints, and the tissue-infiltrating CD8+ T cells were phenotypically heterogeneous. MKI67+ B cells and IgD-CD27-CD11c-CXCR5- double-negative 3 B cells were clonally expanded and infiltrated affected tissue lesions. GZMK+CD4+ cytotoxic T cells colocalized with MKI67+ B cells in the extrafollicular area from affected tissue sites. CONCLUSIONS The above-mentioned cells likely participate in T-B collaborative events, suggesting possible avenues for targeted therapies. Our findings were validated using orthogonal approaches, including multicolor immunofluorescence and the use of comparator disease groups, to support the central role of cytotoxic CD4+ and CD8+ T cells expressing GZMK, amphiregulin, and TGF-β in the pathogenesis of inflammatory fibrotic disorders.

Microb Pathog 2024; 186:106463. [PMID: 38036111 DOI: 10.1016/j.micpath.2023.106463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 11/21/2023] [Accepted: 11/23/2023] [Indexed: 12/02/2023]
Abstract
Amphiregulin (AREG) serves as a ligand for the epidermal growth factor receptor (EGFR) and is involved in vital biological functions, including inflammatory responses, tissue regeneration, and immune system function. Upon interaction with the EGFR, AREG initiates a series of signaling cascades necessary for several physiological activities, such as metabolism, cell cycle regulation, and cellular proliferation. Recent findings have provided evidence for the substantial role of AREG in maintaining the equilibrium of homeostasis in damaged tissues and preserving epithelial cell structure in the context of viral infections affecting the lungs. The development of resistance to influenza virus infection depends on the presence of type 1 cytokine responses. Following the eradication of the pathogen, the lungs are subsequently colonized by several cell types that are linked with type 2 immune responses. These cells contribute to the process of repairing and resolving the tissue injury and inflammation caused by infections. Following influenza infection, the activation of AREG promotes the regeneration of bronchial epithelial cells, enhancing the tissue's structural integrity and increasing the survival rate of infected mice. In the same manner, mice afflicted with influenza experience rapid mortality due to a subsequent bacterial infection in the pulmonary region when both bacterial and viral infections manifest concurrently inside the same host. The involvement of AREG in bacterial infections has been demonstrated. The gene AREG experiences increased transcriptional activity inside host cells in response to bacterial infections caused by pathogens such as Escherichia coli and Neisseria gonorrhea. In addition, AREG has been extensively studied as a mitogenic stimulus in epithelial cell layers. Consequently, it is regarded as a prospective contender that might potentially contribute to the observed epithelial cell reactions in helminth infection. Consistent with this finding, mice that lack the AREG gene exhibit a delay in the eradication of the intestinal parasite Trichuris muris. The observed delay is associated with a reduction in the proliferation rate of colonic epithelial cells compared to the infected animals in the control group. The aforementioned findings indicate that AREG plays a pivotal role in facilitating the activation of defensive mechanisms inside the epithelial cells of the intestinal tissue. The precise cellular sources of AREG in this specific context have not yet been determined. However, it is evident that the increased proliferation of the epithelial cell layer in infected mice is reliant on CD4+ T cells. The significance of this finding lies in its demonstration of the crucial role played by the interaction between immunological and epithelial cells in regulating the AREG-EGFR pathway. Additional research is necessary to delve into the cellular origins and signaling mechanisms that govern the synthesis of AREG and its tissue-protective properties, independent of infection.

Abstract
The relationship between host organisms and their microbiota has co-evolved towards an inter-dependent network of mutualistic interactions. This interplay is particularly well studied in the gastrointestinal tract, where microbiota and host immune cells can modulate each other directly, as well as indirectly, through the production and release of chemical molecules and signals. In this review, we define the functional impact of transforming growth factor-beta (TGF-β) on this complex interplay, especially through its modulation of the activity of local regulatory T cells (Tregs), type 17 helper (Th17) cells, innate lymphoid cells (ILCs) and B cells.

Abstract
Type 2 inflammatory responses can be elicited by diverse stimuli, including toxins, venoms, allergens, and infectious agents, and play critical roles in resistance and tolerance associated with infection, wound healing, tissue repair, and tumor development. Emerging data suggest that in addition to characteristic type 2-associated cytokines, the epidermal growth factor (EGF)-like molecule Amphiregulin (AREG) might be a critical component of type 2-mediated resistance and tolerance. Notably, numerous studies demonstrate that in addition to the established role of epithelial- and mesenchymal-derived AREG, multiple leukocyte populations including mast cells, basophils, group 2 innate lymphoid cells (ILC2s), and a subset of tissue-resident regulatory CD4(+) T cells can express AREG. In this review, we discuss recent advances in our understanding of the AREG-EGF receptor pathway and its involvement in infection and inflammation and propose a model for the function of this pathway in the context of resistance and tissue tolerance.

Abstract
Amphiregulin (AREG) is one of the ligands of the epidermal growth factor receptor (EGFR). AREG plays a central role in mammary gland development and branching morphogenesis in organs and is expressed both in physiological and in cancerous tissues. Various studies have highlighted the functional role of AREG in several aspects of tumorigenesis, including self-sufficiency in generating growth signals, limitless replicative potential, tissue invasion and metastasis, angiogenesis, and resistance to apoptosis. The oncogenic activity of AREG has already been described in the most common human epithelial malignancies, such as lung, breast, colorectal, ovary and prostate carcinomas, as well as in some hematological and mesenchymal cancers. Furthermore, AREG is also involved in resistance to several cancer treatments. In this review, we describe the various roles of AREG in oncogenesis and discuss its translational potential, such as the development of anti-AREG treatments, based on AREG activity. In the last decade, independent groups have reported successful but sometimes contradictory results in relation to the potential of AREG to serve as a prognostic and/or predictive marker for oncology, especially with regard to anti-EGFR therapies. Thus, we also discuss the potential usefulness of using AREG as a therapeutic target and validated biomarker for predicting cancer outcomes or treatment efficacy.

Abstract
Whereas the direct action of sex steroids, namely of androgens, on prostate cell division was questioned as early as in the 1970s, and remains so, the interest in prostatic growth factors (GFs) is rather recent but has expanded tremendously in the last five years. This lag period can be partly explained by the fact that, at the time, androgen receptors had just been discovered, and newly developed hormonal regimens or strategies to treat patients with prostate carcinoma (PCa) or epithelioma had generated great enthusiasm and hopes in the medical and scientific community. Another point to consider was the difficulty in maintaining prostate tissues in organ cultures and the relative novelty of culturing prostate epithelial cells in monolayers. Failures of sex steroids to elicit a direct positive response on prostate cell divisionin vitro, as seenin vivo, were interpreted as resulting from inappropriate models or culture conditions. However, the increasing number of reports confirming the lack of mitogenic activity of sex steroidsin vitro, coupled with the powerful mitogenic activity of GFs displayed in other systems, the discovery of GF receptors (GF-Rs), and the elucidation of their signalling pathways showing sex steroid receptors as potential substrates of GF-activated protein kinases gradually led to an increased interest in the putative role of GFs in prostate physiopathology. Of utmost importance was the recognition that hormone refractiveness was responsible for PCa progression, and for the poor outcome of patients with advanced disease under endocrine therapies. This problem remains a major issue and it raises several key questions that need to be solved at the fundamental and clinical levels.

Abstract
Cyclooxygenase-2 (COX-2) is a key enzyme in the production of prostaglandins and thromboxanes from free arachidonic acid. Increasing evidence suggests that COX-2 plays a role in tumorigenesis. A variety of stimuli induce COX-2 and it is overexpressed in many tumors, including non-small cell lung cancer (NSCLC). We studied the regulation of COX-2 expression in immortalized human bronchial epithelial cells (HBECs) by transforming growth factor-beta1 (TGF-beta1) and epidermal growth factor (EGF) because these two growth factors are present in both the pulmonary milieu of those at risk for lung cancer as well as in the tumor microenvironment. EGF significantly enhanced TGF-beta1-mediated induction of COX-2 and corresponding prostaglandin E2 (PGE2) production. TGF-beta1 and EGF induced COX-2 at the transcriptional and post-transcriptional levels. EGF receptor (EGFR) inhibition, neutralizing antibody against amphiregulin, or mitogen-activated protein kinase kinase (MEK) inhibition blocked TGF-beta1-mediated COX-2 induction. COX-2 induction by TGF-beta1 depended upon Smad3 signaling and required the activity of EGFR or its downstream mediators. Autocrine amphiregulin signaling maintains EGFR in a constitutively active state in HBECs, allowing for COX-2 induction by TGF-beta1. Thus, EGFR ligands, which are abundant in the pulmonary microenvironment of those at risk for lung cancer, potentiate and are required for COX-2 induction by TGF-beta1 in HBEC. These findings emphasize the central role of EGFR signaling in COX-2 induction by TGF-beta1 and suggest that inhibition of EGFR signaling should be investigated further for lung cancer prevention.

Abstract
Expression array data for >3000 individual clones from two suppression subtractive hybridization libraries revealed 147 genes overexpressed in non-small-cell lung cancer (NSCLC) cell lines. Of these 147 genes, 30 genes have previously unknown cancer association and 65 genes have been associated with cancers other than NSCLC. The identification of 52 genes previously associated with NSCLC by different methodologies supports the validity of the strategy used here. Of the 147 genes, 19 have no prior named Unigene cluster designation, and are designated herein as L1 to L19. Quantitative real-time PCR and cancer profiling arrays were used as independent validation tools to confirm tumor overexpression for five of the 'L' genes in tumor cell lines and patient samples from NSCLC and other cancers. Follow-up studies for candidate NSCLC-associated genes can be useful in providing valuable insight into the etiology of lung cancer as well as providing potentially interesting diagnostic or therapeutic targets for further investigation.

Abstract
We previously demonstrated that a ligand-blocking monoclonal antibody (mAb) against the epidermal growth factor-receptor (EGF-R), LA1, induced morphological conversion from epithelial-like to epithelial of the human lung cancer cell line, H322. This was accompanied by an up-regulation of epithelial cadherin (E-cadherin) expression (Clin. Cancer Res. 5 (1999) 681). In the present paper, we show that mAb LA1 induces the epithelial-like to epithelial conversion of the human lung cancer cell line, A549. In A549 and H322 cells, which express a detectable amount of EGF-R (ErbB-1), ErbB-2, ErbB-3, and ErbB-4 receptors, the LA1 mAb induces up-regulation of the E-cadherin/catenin complex (alpha-, beta-, and gamma-catenins). This is associated with re-localization of E-cadherin, alpha-catenin, (and to a lesser extent beta-catenin), but not gamma-catenin. Additionally, we report that mAb LA1 inhibits cell motility. In contrast, epidermal growth factor (EGF) or heparin-binding EGF-like growth factor (HB-EGF) induces the epithelial-like to fibroblastoid conversion of A549 and H322 cell lines, slightly reduces the expression of E-cadherin and beta-catenin, but not alpha- and gamma-catenins, and stimulates cell motility. These studies demonstrate that EGF-R modulation regulates the E-cadherin/catenin complex and cell motility in human lung epithelial carcinoma cells. Our results may have important therapeutic implications for the treatment of invasive human lung carcinomas via the restoration of the cadherin/catenin complex using inhibitors of EGF-R.

Abstract
The epidermal growth factor (EFG) family of receptors and their respective ligands play a major role in breast cancer progression and are the targets of new therapeutic approaches. Following immortalization with SV40 T antigen of normal human breast epithelial cells, a transformed variant cell line (NS2T2A1) was selected for its increased tumorigenicity in nude mice. This cell line was shown to have a higher expression of EGF receptors (EGFR) and amphiregulin (AR) when compared to their normal counterparts or less aggressive transformed cells. Dual staining of EGFR and AR was observed in 50-60% of NS2T2A1 cells, while 30-40% cells expressed AR only. To explore the potential tumorigenic role of AR, a 1.1 kb AR cDNA in an antisense orientation was transfected in NS2T2A1 cells. Three clones, selected by hygromycin B, expressed AR antisense RNA (AR AS1, AR AS2 and AR AS3 cell lines) in which AR protein expression was reduced (ranging from about 50 to < 5%). The anchorage-independent growth of AR AS cell lines was reduced to levels ranging from 32.4-6.8% relative to the control cell line transfected with the vector alone. The clones expressing AR antisense RNA showed a reversion of the malignant phenotype when injected in nude mice, since a significant reduction of tumor intake was observed coincident with a significant tumor mass reduction (> 96%). Moreover, intra-tumoral vascularization decreased significantly in tumors derived from AR AS cells (26.7, 70.7 and 50.4% of control). These in vitro and in vivo data reveal the oncogenic nature of AR in transformed breast epithelial cells and imply a role for AR in tumor angiogenesis.

Abstract
Stromal and epithelial components surrounding neoplastic cells are believed to be important in tumor regulation. We have studied the effects of stromal and epithelial cells on the proliferation of a variety of breast-cancer epithelial cell lines. Co-culture experiments were performed in which the 2 cell types were separated by a microporous membrane. Under these conditions, fibroblasts from normal breast tissues inhibited the proliferation of MCF-7 cells, but not that of immortalized normal S2T2 cells. In contrast, fibroblasts from cancerous breast tissues did not influence the proliferation of the 2 cell lines tested. Conditioned media (CM) of breast fibroblasts derived from normal tissues were not able to affect MCF-7 cell growth, suggesting complex paracrine interactions between both cell types. Normal breast epithelial cells (NBEC) have also been tested for their ability to regulate the proliferation of breast-cancer epithelial cell lines. Co-culture experiments demonstrated that NBEC inhibited a variety of breast-cancer cell lines. CM from NBEC induced similar results and the inhibitory effect appeared to be specific for epithelial cells from tumorous breast. Moreover, CM from NBEC and normal fibroblasts were shown to contain more TGF beta 1 and amphiregulin than those of MCF-7 cells. We conclude that both the tissue origin and the target tumor cell's phenotype will determine the extent of proliferative response. More important, the tumor-cell growth inhibition induced by fibroblasts and epithelial cells of normal breast tissue may constitute a tumor-growth-regulatory mechanism.

Abstract
Although the intestinal epithelium is one of the most rapidly renewing tissues, little is known about the major growth factors that control the rate of cell replacement and migration. Recently, a primary culture model has been described for the developing rat small intestinal epithelium, which permits epithelial growth while maintaining interactions with associated stromal cells, thereby possessing several contextual advantages over established cell lines (Evans et al., 1992). We have used this model to begin to determine the factors that may be involved in controlling intestinal epithelial cell proliferation. Under the conditions examined, no single growth factor promoted exclusive proliferation of epithelial cells; stromal cell proliferation was also apparent. The most potent stimulators of epithelial proliferation were insulin and insulin-like growth factor 1 (IGF-1). These factors also appeared to inhibit migration of the epithelial cells. 5-10 ng/ml EGF, 5-20 ng/ml TGF alpha, and 10-20 ng/ml PDGF also slightly increased epithelial cell numbers. Cell proliferation was inhibited by 0.1 ng/ml TGF beta-1. In Dulbecco's modified Eagle's medium (DMEM) containing 0.25 IU/ml insulin, glucose levels of 2-3 g/liter permitted epithelial growth with limited expansion of the stromal cell population. Higher levels of glucose further stimulated the nonepithelial cell types. Transferrin was also a potent stimulator of both cell types.

Abstract
Amphiregulin (AR) is an epidermal growth factor (EGF)-related peptide that operates exclusively through the EGF receptor and that can bind to heparin. AR also possesses nuclear localization sequences in the extended NH2-terminal region suggesting an additional intracellular site of action. AR mRNA and protein expression have been detected in primary human mammary epithelial cell strains, nontransformed human mammary epithelial cell lines, several human breast cancer cell lines, and primary human breast carcinomas. The frequency and levels of AR protein expression are generally higher in invasive breast carcinomas than in ductal carcinomas in situ or in normal, noninvolved mammary epithelium. In addition, AR can function as an autocrine and/or juxtacrine growth factor in human mammary epithelial cells that have been transformed by an activated c-Ha-ras proto-oncogene or by overexpression of c-erb B-2. AR expression is also enhanced by mammotrophic hormones such as estrogens and other growth factors such as EGF.
