Abstract
Rapid reaction to microbes invading mucosal tissues is key to protect the host against disease. Respiratory tissue-resident memory T (TRM ) cells provide superior immunity against pathogen infection and/or re-infection, due to their presence at the site of pathogen entry. However, there has been emerging evidence that exuberant TRM -cell responses contribute to the development of various chronic respiratory conditions including pulmonary sequelae post-acute viral infections. In this review, we have described the characteristics of respiratory TRM cells and processes underlying their development and maintenance. We have reviewed TRM -cell protective functions against various respiratory pathogens as well as their pathological activities in chronic lung conditions including post-viral pulmonary sequelae. Furthermore, we have discussed potential mechanisms regulating the pathological activity of TRM cells and proposed therapeutic strategies to alleviate TRM -cell-mediated lung immunopathology. We hope that this review provides insights toward the development of future vaccines or interventions that can harness the superior protective abilities of TRM cells, while minimizing the potential for immunopathology, a particularly important topic in the era of coronavirus disease 2019 (COVID-19) pandemic.

Abstract
Lung involvement is the most common and serious organ manifestation in patients with inflammatory rheumatic disease (IRD). The type of pulmonary involvement can differ, but the most frequent is interstitial lung disease (ILD). The clinical manifestations of IRD-ILD and severity can vary from subclinical abnormality to dyspnea, respiratory failure, and death. Consequently, early detection is of significant importance. Pulmonary function test (PFT) including diffusing capacity of the lungs for carbon monoxide (DLCO), and forced vital capacity (FVC) as well as high-resolution computed tomography (HRCT) are the standard tools for screening and monitoring of ILD in IRD-patients. Especially, the diagnostic accuracy of HRCT is considered to be high. Magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT) allow both morphological and functional assessment of the lungs. In addition, biomarkers (e.g., KL-6, CCL2, or MUC5B) are being currently evaluated for the detection and prognostic assessment of ILD. Despite the accuracy of HRCT, invasive diagnostic methods such as bronchoalveolar lavage (BAL) and lung biopsy are still important in clinical practice. However, their therapeutic and prognostic relevance remains unclear. The aim of this review is to give an overview of the individual methods and to present their respective advantages and disadvantages in detecting and monitoring ILD in IRD-patients in the clinical routine.

Abstract
Immune cells have been implicated in Idiopathic Pulmonary Fibrosis (IPF), but the phenotypes and effector mechanisms of these cells remain incompletely characterized. We performed mass cytometry to quantify immune/inflammatory cell subsets in lungs of 12 patients with IPF and 15 organ donors without chronic lung disease and utilized existing single-cell RNA-sequencing (scRNA-seq) data to investigate transcriptional profiles of immune cells over-represented in IPF. Among myeloid cells, we found increased numbers of alveolar macrophages (AMØs) and dendritic cells (DCs) in IPF, as well as a subset of monocyte-derived DC. In contrast, monocyte-like cells and interstitial macrophages were reduced in IPF. Transcriptomic profiling identified an enrichment for interferon-γ (IFN-γ) response pathways in AMØs and DCs from IPF, as well as antigen processing in DCs and phagocytosis in AMØs. Among T cells, we identified three subset of memory T cells that were increased in IPF, including CD4+ and CD8+ resident memory T cells (TRM), and CD8+ effector memory (TEMRA) cells. The response to IFN-γ pathway was enriched in CD4 TRM and CD8 TRM cells in IPF, along with T cell activation and immune response-regulating signaling pathways. Increased AMØs, DCs, and memory T cells were present in IPF lungs compared to control subjects. In IPF, these cells possess an activation profile indicating increased IFN-γ signaling and up-regulation of adaptive immunity in the lungs. Together, these studies highlight critical features of the immunopathogenesis of IPF.

Abstract
Interstitial lung diseases (ILDs) are a heterogeneous group of diseases characterized by varying degrees of inflammation and fibrosis of the pulmonary interstitium. The interrelations between multiple immune cells and stromal cells participate in the pathogenesis of ILDs. While fibroblasts contribute to the development of ILDs through secreting extracellular matrix and proinflammatory cytokines upon activation, T cells are major mediators of adaptive immunity, as well as inflammation and autoimmune tissue destruction in the lung of ILDs patients. Fibroblasts play important roles in modulating T cell recruitment, differentiation and function and conversely, T cells can balance fibrotic sequelae with protective immunity in the lung. A more precise understanding of the interrelation between fibroblasts and T cells will enable a better future therapeutic design by targeting this interrelationship. Here we highlight recent work on the interactions between fibroblasts and T cells in ILDs, and consider the implications of these interactions in the future development of therapies for ILDs.

Abstract
Background The mechanisms driving the transition from inflammation to fibrosis in sarcoidosis patients are poorly understood; prognostic features are lacking. Immune cell profiling may provide insights into pathogenesis and prognostic factors of the disease. This study aimed to establish associations in simultaneous of lymphocyte subset profiles in the blood, bronchoalveolar lavage fluid (BALF), and lung biopsy tissue in the patients with newly diagnosed sarcoidosis. Methods A total of 71 sarcoid patients (SPs) and 20 healthy controls (HCs) were enrolled into the study. CD31, CD38, CD44, CD103 positive T lymphocytes in blood and BALF were analysed. Additionally, the densities of CD4, CD8, CD38, CD44, CD103 positive cells in lung tissue biopsies were estimated by digital image analysis. Results Main findings: (I) increase of percentage of CD3+CD4+CD38+ in BALF and blood, and increase of percentage of CD3+CD4+CD44+ in BALF in Löfgren syndrome patients comparing with patients without Löfgren syndrome, (II) increase of percentage of CD3+CD4+103+ in BALF and in blood in patients without Löfgren syndrome (comparing with Löfgren syndrome patients) and increase of percentage of CD3+CD4+103+ in BALF and in blood in more advanced sarcoidosis stage. (III) Increasing percentage of BALF CD3+CD4+CD31+ in sarcoidosis patients when comparing with controls independently of presence of Löfgren syndrome, smoking status or stage of sarcoidosis. Several significant correlations were found. Conclusions Lymphocyte subpopulations in blood, BALF, and lung tissue were substantially different in SPs at the time of diagnosis compared to HCs. CD3+CD4+CD31+ in BALF might be a potential supporting marker for the diagnosis of sarcoidosis. CD3+CD4+CD38+ in BALF and blood and CD3+CD4+CD44+ in BALF may be markers of the acute immune response in sarcoidosis patients. CD4+CD103+ T-cells in BALF and in blood are markers of the persistent immune response in sarcoidosis patients and are potential prognostic features of the chronic course of this disease.

Abstract
Idiopathic pulmonary fibrosis (IPF) affects hundreds of thousands of people worldwide, reducing their quality of life and leading to death from respiratory failure within years of diagnosis. Treatment options remain limited, with only two FDA-approved drugs available in the United States, neither of which reverse the lung damage caused by the disease or prolong the life of individuals with IPF. The only cure for IPF is lung transplantation. In this review, we discuss recent major advances in our understanding of the role of the immune system in IPF that have revealed immune dysregulation as a critical driver of disease pathophysiology. We also highlight ways in which an improved understanding of the immune system's role in IPF may enable the development of targeted immunomodulatory therapies that successfully halt or potentially even reverse lung fibrosis.

Abstract
The interaction of tolerogenic CD103+ dendritic cells (DCs) with regulatory T (Tregs) cells modulates immune responses by inducing immune tolerance. Hence, we determined the proportion of these cells in the peripheral blood mononuclear cells (PBMC) of asthmatic patients. We observed lower trends of CD11b-CD103+ DCs and CD86 within CD11b-CD103+ DCs, while increased levels of Foxp3 expressing CD25+/-TNFR2+ cells in asthmatics. There was a positive correlation in the expression of Foxp3 within CD3+CD4+CD25+TNFR2+ Tregs and CD11b-CD103+ as well as the expression of CD86 within HLA-DR+CD11c+CD11b-CD103+ DCs. In conclusion, we suggest that the increased levels of Tregs in blood could continuously suppress the T helper 2 (Th2) cells activation in the circulation which is also supported by the increase of anti-inflammatory cytokines IL-10 and TNF. Overall, functional immunoregulation of the regulatory cells, particularly Tregs, exhibit immune suppression and induce immune tolerance linked with the immune activation by the antigen presenting cells (APC).

Abstract
BACKGROUND Recent studies have shown that CD103 is an important marker for tissue-resident memory T cells (TRM) which plays an important role in anti-infection. However, the role of CD103+ TRM was not elucidated in the progress of S. japonicum infection induced disease. METHODS 6-8 weeks old C57BL/6 mice were infected by S. japonicum. Mice were sacrificed and the lungs were removed 5-6 weeks after infection. Immunofluorescent staining and Q-PCR were performed to identify the expression of CD103 molecule. Single cellular populations were made, percentages of CD103 on both CD4+ and CD8+ T lymphocytes were dynamical observed by flow cytometry (FCM). Moreover, the expression of memory T cells related molecules CD69 and CD62L, T cell function associated molecules CD107a, IFN-γ, IL-4, IL-9, and IL-10 were compared between CD103+ CD4+ and CD8+ T cells by FCM. RESULTS CD103+ cells were emerged in the lung of both naive and S. japonicum infected mice. Both the percentage and the absolute numbers of pulmonary CD4+ and CD8+ cells were increased after S. japonicum infection (P < 0.05). The percentage of CD103+ cells in CD8+ T cells decreased significantly at the early stage of S. japonicum infection (P < 0.05). Increased CD69, decreased CD62L and CD107a expressions were detected on both CD4+ and CD8+ CD103+ T cells in the lungs of infected mice (P < 0.05). Compared to CD8+ CD103+ T cells, CD4+ CD103+ T cells from infected mice expressed higher level of CD69 and lower level CD62L molecules (P < 0.05). Moreover, higher percentage of IL-4+, IL-9+ and IL-10+ cells on CD4+ CD103+ pulmonary T cells was found in infected mice (P < 0.05). Significantly increased IL-4 and IL-9, and decreased IFN-γ expressing cells were detected in CD8+CD103+ cells of infected mice (P < 0.05). CONCLUSIONS CD103-expressing pulmonary CD4+ and CD8+ T cells play important roles in mediating S. japonicum infection induced granulomatous inflammation in the lung.

Bronchoalveolar lavage characteristics correlate with HLA tag SNPs in patients with Löfgren's syndrome and other sarcoidosis. Clin Exp Immunol 2019; 196:249-258.

Abstract
Genetic susceptibility for sarcoidosis and Löfgren's syndrome (LS) has been associated with prognosis. Human leukocyte antigen (HLA)-DRB1*03 is over-represented in LS, and is associated with a good prognosis, whereas HLA-DRB1*15-positive patients have a more chronic course of sarcoidosis. These HLA-DRB1 types can be easily tagged by single nucleotide polymorphisms (SNPs). Our aim was to evaluate the association between these tag SNPs and bronchoalveolar lavage (BAL) characteristics. In 29 patients, both complete HLA-DRB1* locus genotyping and SNP tagging was performed in parallel. HLA-DRB1 type was inferred from the presence of *03 tag rs2040410 allele A and referred to as *03. HLA-DRB1*15 was inferred from the presence of tag SNP rs3135388 allele A and referred to as *15. For BAL analysis, 122 patients with LS and 165 patients with non-LS sarcoidosis were included. BAL lymphocyte subsets were analyzed by flow cytometry. The presence of tag SNPs completely corresponded with HLA-DRB1*03/*15 genotypes in all 29 patients in whom both HLA-DRB1* genotyping and SNP tagging was performed. In all patients together, *03+ /*15- patients showed a higher CD4+ /CD8+ ratio than *03- /*15+ (P = 0·004) and *03- /*15- (P = 0·001). LS patients with *03+ /*15- had a lower BAL lymphocyte count compared to *03- /*15+ patients (P = 0·011). Non-LS sarcoidosis patients with *03+ /*15- patients showed a decreased CD103+ CD4+ /CD4+ ratio compared to *03- /*15+ patients (P = 0·045) and *03- /*15- patients (P = 0·018). We found that HLA-DRB1*03 and HLA-DRB1*15 can be approximated by genotyping of tag SNPs and corresponds with the degree of lymphocytosis and cell phenotypes in BAL in both LS and non-LS sarcoidosis patients.

Abstract
OBJECTIVES Sarcoidosis is an inflammatory disorder in which elevated numbers of activated T cells are found in the lung. HLA-DRB1*0301(pos) (DR3(pos) ) patients are characterized by good prognosis and an accumulation of lung CD4(pos) T cells expressing the T-cell receptor (TCR) gene segment AV2S3. Our aim was to phenotype lung and blood T-cell subsets in distinct patient groups to better understand the function of these subsets. DESIGN Bronchoalveolar lavage (BAL) fluid and whole blood were obtained from a total of 22 patients with sarcoidosis, of whom 11 were DR3(pos) . Using eight-colour flow cytometry, phenotyping of T cells was performed with regard to CD3, CD4, CD8, CD25, CD27, CD45RO, CD57, CD69, CD103, FOXP3 and TCR AV2S3. RESULTS DR3(pos) patients had fewer FOXP3(pos) (regulatory) CD45RO(pos) (memory) BAL T cells than DR3(neg) patients. Fewer AV2S3(pos) T cells were FOXP3(pos) , compared with AV2S3(neg) cells, thus indicating an effector function and not a regulatory role for this subset. Fewer lung and blood AV2S3(pos) T cells were CD25(pos) CD27(pos) , and more were CD25(neg) CD27(neg) and CD69(pos) , compared with AV2S3(neg) T cells, indicating a higher degree of differentiation and activation in both compartments. CONCLUSION Our main findings were a lower proportion of regulatory T cells in DR3(pos) patients, together with the accumulation of AV2S3(pos) T cells with a highly activated effector phenotype in the lungs of these patients. This may provide for efficient elimination of a harmful antigen in DR3(pos) patients and could thus help to explain the spontaneous recovery typically seen in these patients.

Abstract
During the immune response to influenza infection, activated T cells are distributed to both lymphoid and extralymphoid tissues, including the infected airways where direct recognition of viral Ag-bearing cells takes place. The collagen-binding alpha(1)beta(1) integrin VLA-1 is essential for the development of memory CD8(+) T cells in the airways, and although expressed by some CD4(+) T cells, its significance has not been demonstrated. We investigated the role of VLA-1 on virus-specific CD4(+) T cells during and after primary or secondary influenza infection of mice. The proportion of CD4(+) cells expressing CD49a (alpha(1) integrin) was low in all tissues sampled during primary infection but increased in the airways after viral clearance. Furthermore, during the first 24 h of a secondary influenza challenge, the majority of IFN-gamma-secreting effector CD4(+) T cells from the airways was in the CD49a(+) population. Airway CD49a(+)CD4(+) cells also expressed reduced markers of apoptosis compared with CD49a(-) cells, and fewer memory or effector CD4(+) cells could be recovered from airways of alpha(1)(-/-) mice, although lymphoid tissues appeared unaffected. These data suggest VLA-1 expression defines a population of tissue memory CD4(+) T cells that act as rapid effectors upon reinfection, and VLA-1 expression is integral to their accumulation in the airways.

Abstract
Lymphocytes play a crucial role in lung inflammation. Different interstitial lung diseases may show distinct lymphocyte activation profiles. The aim of this study was to examine the expression of a variety of activation markers on T lymphocyte subsets from blood and bronchoalveolar lavage fluid (BALF) of patients with different granulomatous interstitial lung diseases and healthy controls. Bronchoalveolar lavage cells and blood cells from 23 sarcoidosis patients, seven patients with hypersensitivity pneumonitis and 24 healthy controls were analysed. Lymphocyte activation status was determined by flow cytometry. Lymphocytes were stained with antibodies against CD3, CD4, CD8, CD25, CD28, CD69, very late antigen-1 (VLA)-1, VLA-4 and human leucocyte antigen D-related (HLA-DR). In general, CD28, CD69 and VLA-1 expression on BALF CD4+ lymphocytes and HLA-DR expression on BALF CD8+ lymphocytes was different in patients with hypersensitivity pneumonitis and sarcoidosis patients with parenchymal involvement. This BALF lymphocyte phenotype correlated with carbon monoxide diffusing lung capacity (Dlco) values across interstitial lung diseases (ILD) (r2 = 0.48, P = 0.0002). In sarcoidosis patients, CD8+CD28(null) blood lymphocytes correlated with lower Dlco values (r = -0.66, P = 0.004), chronic BALF lymphocyte activation phenotype (r2 = 0.65, P < 0.0001), radiographic staging (stage I versus stage II and higher, P = 0.006) and with the need for corticosteroid treatment (P = 0.001). Higher expression of CD69, VLA-1 and HLA-DR and lower expression of CD28 on BALF lymphocytes suggests prolonged stimulation and chronic lymphocyte activation in patients with ILD. In sarcoidosis, blood CD8+CD28(null) cells might be a new biomarker for disease severity but needs further investigation.

Abstract
The E-cadherin receptor CD103 (alpha(E)beta(7)-integrin) is expressed on specific populations of pulmonary dendritic cells (DC) and T cells. However, CD103 function in the lung is not well understood. Matrilysin (MMP-7) expression is increased in lung injury and cleaves E-cadherin from injured lung epithelium. Thus, to assess matrilysin effects on CD103-E-cadherin interactions in lung injury, wild-type, CD103(-/-), and Mmp7(-/-) mice, in which E-cadherin isn't cleaved in the lung, were treated with bleomycin or bleomycin with nFMLP to reverse the defect in acute neutrophil influx seen in Mmp7(-/-) mice. Pulmonary CD103(+) DC were significantly increased in injured wild-type compared with Mmp7(-/-) mice, and CD103(+) leukocytes showed significantly enhanced interaction with E-cadherin on injured wild-type epithelium than with Mmp7(-/-) epithelium in vitro and in vivo. Bleomycin-treated CD103(-/-) mice had persistent neutrophilic inflammation, increased fibrosis, and increased mortality compared with wild-type mice, a phenotype that was partially recapitulated in bleomycin/nFMLP-treated Mmp7(-/-) mice. Soluble E-cadherin increased IL-12 and IL-10 and reduced IL-6 mRNA expression in wild-type bone marrow-derived DC but not in CD103(-/-) bone marrow-derived DC. Similar mRNA patterns were seen in lungs of bleomycin-injured wild-type, but not CD103(-/-) or Mmp7(-/-), mice. In conclusion, matrilysin regulates pulmonary localization of DC that express CD103, and E-cadherin cleavage may activate CD103(+) DC to limit inflammation and inhibit fibrosis.

Abstract
Human gammadelta T-lymphocytes are believed to regulate local immune defense and enhance resistance against invading microbes, although their precise function remains unknown. Herein, we addressed the question whether gammadelta T-lymphocytes mediate these processes via synthesis of MMP-7, a protease closely associated with both epithelial repair and mucosal defense. Blood and bronchoalveolar gammadelta T-lymphocytes were cultured in the absence and presence of isopentenyl pyrophosphate (IPP) or TGF-beta1/IL-15 for 24 h, and assessed for the expression and synthesis of MMP-1, MMP-7, and MMP-9. Resting human gammadelta T-lymphocytes constitutively expressed MMP-9 mRNA, a marginal or no MMP-7 and MMP-1 mRNA. In the presence of IPP (3 microg/ml), expression of MMP-7 mRNA significantly increased, whereas TGF-beta1/IL-15 had no effect. Further, quiescent gammadelta T-lymphocytes obtained from bronchoalveolar lavage (BAL) fluid showed a weak or no MMP-7 mRNA signal which was raised significantly following stimulation with IPP. In Western blot analysis, a 28-kDa pro-matrilysin could be detected both in cell lysates (2 days) and supernatants (5 days) with a four- to sevenfold increased signal following IPP-stimulation of the gammadelta T-lymphocytes. In conclusion, the data demonstrate for the first time that both human blood and BAL gammadelta T-lymphocytes express MMP-7 mRNA and synthesize MMP-7-protein. This unfolds a new perspective for the understanding of gammadelta T-lymphocyte function.

Abstract
The alpha1beta1 integrin, also known as "very late antigen" (VLA)-1, is normally expressed on mesenchymal cells, some epithelial cells, activated T cells, and macrophages, and interacts, via the I-domain of the extracellular domain of the alpha1 subunit, with collagen molecules in the extracellular matrix (ECM). By "outside-in" transmembranal signaling to the interior of the cell, it mediates adhesion, migration, proliferation, remodeling of the ECM, and cytokine secretion by endothelial cells, mesangial cells, fibroblasts, and immunocytes. Importantly, its expressions and functions are enhanced by inflammatory cytokines including interferon (IFN)gamma and tumor necrosis factor (TNF)alpha, thus augmenting angiogenesis and fibrosis linked, in particular, to inflammation. Moreover, within the immune system, VLA-1 marks effector memory CD4+ and CD8+ T cells that are retained in extralymphatic tissues by interactions of the integrin with collagen and produce high levels of IFNgamma. Thus, immune-mediated inflammation in vivo is inhibited by blockade of the VLA-1-collagen interaction in experimental animal models of arthritis, colitis, nephritis, and graft versus host disease (GVHD), suggesting that inhibiting the interaction of the alpha1 I-domain with its ligands or modulating "outside-in" signaling by VLA-1 would be a useful approach in the human diseases simulated by these experimental models.
