Abstract
Since the advent of anti-PD1 immune checkpoint inhibitor (ICI) immunotherapy, cutaneous melanoma has undergone a true revolution with prolonged survival, as available 5-year updates for progression-free survival and overall survival demonstrate a durable clinical benefit for melanoma patients receiving ICI. However, almost half of patients fail to respond to treatment, or relapse sooner or later after the initial response to therapy. Little is known about the reasons for these failures. The identification of biomarkers seems necessary to better understand this resistance. Among these biomarkers, HLA-DR, a component of MHC II and abnormally expressed in certain tumor types including melanoma for unknown reasons, seems to be an interesting marker. The aim of this review, prepared by an interdisciplinary group of experts, is to take stock of the current literature on the potential interest of HLA-DR expression in melanoma as a predictive biomarker of ICI outcome.

Abstract
As the primary barrier between an organism and its environment, epithelial cells are well-positioned to regulate tolerance while preserving immunity against pathogens. Class II major histocompatibility complex molecules (MHC class II) are highly expressed on the surface of epithelial cells (ECs) in both the lung and intestine, although the functional consequences of this expression are not fully understood. Here, we summarize current information regarding the interactions that regulate the expression of EC MHC class II in health and disease. We then evaluate the potential role of EC as non-professional antigen presenting cells. Finally, we explore future areas of study and the potential contribution of epithelial surfaces to gut-lung crosstalk.

Abstract
PURPOSE Histologic markers that differentiate benign and malignant pediatric adrenocortical tumors are lacking. Previous studies have implicated an association of MHC class II expression with adrenocortical tumor prognosis. Here, we determined the expression of MHC class II as well as the cell of origin of these immunologic markers in pediatric adrenocortical tumor. The impact of MHC class II gene expression on outcome was determined in a cohort of uniformly treated children with adrenocortical carcinomas. EXPERIMENTAL DESIGN We analyzed the expression of MHC class II and a selected cluster of differentiation genes in 63 pediatric adrenocortical tumors by Affymetrix Human U133 Plus 2.0 or HT HG-U133+PM gene chip analyses. Cells expressing MHC class II were identified by morphologic and immunohistochemical assays. RESULTS MHC class II expression was significantly greater in adrenocortical adenomas than in carcinomas (P = 4.8 ×10-6) and was associated with a higher progression-free survival (PFS) estimate (P = 0.003). Specifically, HLA-DPA1 expression was most significantly associated with PFS after adjustment for tumor weight and stage. HLA-DPA1 was predominantly expressed by hematopoietic infiltrating cells and undetectable in tumor cells in 23 of 26 cases (88%). CONCLUSIONS MHC class II expression, which is produced by tumor-infiltrating immune cells, is an indicator of disease aggressiveness in pediatric adrenocortical tumor. Our results suggest that immune responses modulate adrenocortical tumorigenesis and may allow the refinement of risk stratification and treatment for this disease.

Abstract
The common mucosal immune system (CMIS) is an interconnecting network of immune structures that provides effective immunity to mucosal surfaces. The structures of the mucosal immune system are fully developed in utero by 28 weeks gestation, but in the absence of intrauterine infection, activation does not occur until after birth. Mucosal immune responses occur rapidly in the first weeks of life in response to extensive antigenic exposure. Maturation of the mucosal immune system and establishment of protective immunity varies between individuals but is usually fully developed in the first year of life, irrespective of gestational age at birth. In addition to exposure to pathogenic and commensal bacteria, the major modifier of the developmental patterns in the neonatal period is infant feeding practices. A period of heightened immune responses occurs during the maturation process, particularly between 1 and 6 months, which coincides with the age range during which most cases of sudden infant death syndrome (SIDS) occur. A hyper-immune mucosal response has been a common finding in infants whose death is classified as SIDS, particularly if in association with a prior upper respiratory infection. Inappropriate mucosal immune responses to an otherwise innocuous common antigen and the resulting inflammatory processes have been proposed as factors contributing to SIDS.

Abstract
During the initiation of an immune response, antigen-presenting cells employ MHC class II antigens as key molecules to present small peptides to CD4-positive lymphocytes. The invariant chain (Ii; CD74) plays a critical role in this process by influencing the expression and peptide loading of the MHC class II molecules. Therefore, coordinate expression of these molecules is believed to play an important role in antigen presentation. This study explores the expression of these molecules in fetal tissues. Formalin-fixed, paraffin-embedded multi-organ tissue blocks from aborted fetuses (age range 7-22 weeks) were immunostained for Ii/CD74 and MHC class II antigens using commercially available monoclonal antibodies for Ii/CD74 (LN2) and MHC class II antigens (LN3), respectively. Coordinate staining for Ii/CD74 and MHC class II antigens was seen in the skin, proximal renal tubules, tips of small intestinal mucosa, and cells of the reticuloendothelial system, including the spleen and thymus. Expression of Ii/CD74, but not of MHC class II antigens, was seen in pulmonary alveolar epithelium in all cases and in testicular Leydig cells (11 of 11 testes examined). The distribution and intensity of staining did not change significantly with age. In conclusion, this study describes distribution of Ii/CD74 and MHC class II antigens in human fetal tissues. Coordinate expression of Ii/CD74 and MHC class II antigens was identified in most fetal tissues, but there were also notable exceptions. In all cases this took the form of expression of Ii/CD74 in the absence of MHC class II expression. Discordance was particularly striking in pulmonary alveolar epithelium and testicular Leydig cells. This suggests that the Ii/CD74 molecule has functional roles in addition to its role in antigen presentation.

Abstract
Expression of major histocompatibility complex (MHC) molecules by pancreatic islets may influence the survival of pancreas or islet grafts in allogeneic recipients. This study compares the presence of MHC class II (HLA-DP, DQ, DX and DR)-positive cells in 27 pancreases and in 10 isolated islet preparations from human donors. Cells expressing MHC class II were present in all tissues examined as histiocytes located in interstitial areas in both the endocrine and nonendocrine components and as endothelial cells in the nonendocrine part. Endocrine, acinar and duct cells were MHC class II negative. In pancreases from donors under the age of 7 years the frequency of MHC class II-positive histiocytes was only one third of that in adults, and they rarely contained MHC class II-positive endothelial cells. The MHC class II-positive histiocytes were further phenotyped as macrophages positive for LCA and acid phosphatase, or dendritic cells negative for the latter markers. Dendritic cells were frequent in adult organs but rare in organs from donors under 7 years of age. In freshly isolated islet preparations from adult donors, less than 1% of the cells were MHC class II positive. These were identified as resident macrophages and dendritic cells. No MHC class II positive cells were encountered in the islet capillaries. The putative role of MHC class II-positive donor cells in allograft rejection suggests that these differences in MHC class II expression influence the immunogenicity of pancreatic and islet grafts in an age-dependent manner.

Abstract
In the external layers of human small and large intestine macrophage-like cells were characterized by immunohistochemical, histochemical and electron-microscopical methods. Using immunohistochemistry and a number of monoclonal antibodies, the presence and distribution of phenotypic subpopulations of macrophages were evaluated. In all locations macrophage-like cells were identified with antibody EBM11, which recognizes CD68 antigen, C3bi which recognizes CD11b, and partly with an antibody which recognizes protein 150,95 (CD11c). Macrophage-like cells in the external muscle layer were HLA-DR-positive (expressing the MHC class-II antigen), in contrast to macrophage-like cells in the subserosa and submucosa. Macrophage-like cells in the external muscle layer were mostly acid phosphatase-negative, and at the electron-microscopic level they were found to have features of macrophages: primary lysosomes, coated vesicles and pits. However, very few secondary lysosomes were present. Birbeck granules were not observed. It is concluded that in the external muscle layer of human small and large intestine numerous macrophages of a special type are present. It is discussed whether this cell type plays a role in gastrointestinal motility and/or has an immunological function.

Abstract
Epithelial HLA class II is differentially expressed (DR >> DP) only after birth in salivary glands and small intestinal mucosa, in contrast to class I determinants and secretory component (SC) which appear early in gestation. However, there is a brisk postnatal increase in SC expression along with the class II induction, suggesting stimulation by cytokines from activated immune cells. T lymphocytes remain quite scanty in postnatal salivary glands, and the striking SC and class II expression might reflect a synergistic effect of IFN-gamma and TFN-alpha on immature epithelial cells. Enhanced epithelial expression of both SC and class II in salivary glands from sudden infant death victims could be the effect of immunostimulation caused by an infectious agent. Strikingly upregulated SC and epithelial class II expression (DR > DP > DQ) is seen in various inflammatory lesions such as obstructive sialadenitis, Sjögren's syndrome, chronic gastritis, and celiac disease. IFN-gamma and TNF-alpha are most likely involved as the expression patterns can be reproduced with these cytokines in vitro on colonic epithelial cell lines. However, these molecules of the Ig supergene family do not show a selective response in epithelia of inflammatory lesions because increased expression is also seen for lysozyme, lactoferrin and some other proteins. ICAM-1 can be upregulated on epithelial cells by various cytokines in vitro although the situation remains uncertain in mucosal inflammation. The expression pattern in IBD is complicated by dysplastic epithelial changes leading to reduced SC levels which may thus, in turn, jeopardize the poly-Ig transport mechanism. Epithelial class II molecules appear to have antigen-presenting properties, but the immunopathologic role of their increased expression in inflammatory disease in terms of induction of autoimmunity and/or abrogation of oral tolerance is a matter of continuing dispute.

Abstract
Fetal (n = 20) and postnatal (n = 40) parotid glands were examined by two-colour immunohistochemistry combining monoclonal and polyclonal antibody reagents to study the expression of HLA class I and II (DR, DP, and DQ), CD45 and CD3. The epithelium lacked class II during fetal life, whereas class I determinants appeared in some acini and most major ducts. Fetal vessels were positive for both class I and class II (mainly DR), suggesting constitutive expression. Some class II-positive (DR greater than DP greater than DQ) histiocytic cells, scattered CD45+ leucocytes, and very few CD3+ T cells were present in the fetal stroma. The epithelium remained DR-negative the first few weeks after birth, but brisk expression was seen subsequently. DP and DQ remained virtually negative in the epithelium throughout the first year. A slight postnatal increase of class II expression (DR greater than DP greater than DQ), along with an apparent decrease in class I, was observed in the endothelium. The number of class II-positive histiocytic cells, CD45+ leucocytes and CD3+ T cells, as well as the proportion of presumably activated (DR+) T cells, increased a few weeks after birth. The local immune system hence seemed to be stimulated by extrinsic factors, but the overall number of T cells nevertheless remained small. Stimuli other than T cell-derived lymphokines, therefore, probably explained the brisk postnatal epithelial DR induction.

Abstract
The immunophenotype of the macrophage population in human fetal tissue was studied, using a panel of monoclonal antibodies against cells of the macrophage/monocyte lineage. Using a double-labelling technique two main populations were observed in tissue from 14 weeks of estimated gestational age (EGA); EBM11+ DR+ and EBM11+ DR- cells of which a small proportion were also RFD7+. Most macrophages were negative with 3.9, an antibody specific for the adhesion molecule P150.95 and LP9 which is specific for a lysosomal enzyme. The exception to this was a small population of positive cells in the thymus. Small numbers of 3.9+ cells were also infrequently observed in tissue at and above 17 weeks of EGA, while occasional RFD9+ cells were only observed in most tissues, before this time. The higher percentage of macrophages were DR+ DQ- DP-, with a few DQ+ cells appearing at 15 weeks of EGA. In the thymus, DQ+ cells outnumbered DP+ cells especially in the medulla. These results indicate the heterogeneous and immature nature of the fetal macrophage population and point to the importance of age, tissue-specific factors and probable immune mediators in macrophage differentiation.
