Abstract
The tumor microenvironment is composed of tumor cells, stromal cells and leukocytes, including innate and adaptive immune cells, and represents an ecological niche that regulates tumor development and progression. In general, inflammatory cells are considered to contribute to tumor progression through various mechanisms, including the formation of an immunosuppressive microenvironment. Macrophages and neutrophils are important components of the tumor microenvironment and can act as a double-edged sword, promoting or inhibiting the development of the tumor. Targeting of the immune system is emerging as an important therapeutic strategy for cancer patients. However, the efficacy of the various immunotherapies available is still limited. Given the crucial importance of the crosstalk between macrophages and neutrophils and other immune cells in the formation of the anti-tumor immune response, targeting these interactions may represent a promising therapeutic approach against cancer. Here we will review the current knowledge of the role played by macrophages and neutrophils in cancer, focusing on their interaction with other immune cells.

Effect of B7-H4 downregulation induced by Toxoplasma gondii infection on dysfunction of decidual macrophages contributes to adverse pregnancy outcomes. Parasit Vectors 2022; 15:464. [PMID: 36514159 PMCID: PMC9746109 DOI: 10.1186/s13071-022-05560-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 10/20/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Toxoplasma gondii infection during pregnancy can lead to fetal defect(s) or congenital complications. The inhibitory molecule B7-H4 expressed on decidual macrophages (dMφ) plays an important role in maternal-fetal tolerance. However, the effect of B7-H4 on the function of dMφ during T. gondii infection remains unclear. METHODS Changes in B7-H4 expression on dMφ after T. gondii infection were explored both in vivo and in vitro. B7-H4-/- pregnant mice (pregnant mice with B7-H4 gene knockout) and purified primary human dMφ treated with B7-H4 neutralizing antibody were used to explore the role of B7-H4 signaling on regulating the membrane molecules, synthesis of arginine metabolic enzymes and cytokine production by dMφ with T. gondii infection. Also, adoptive transfer of dMφ from wild-type (WT) pregnant mice or B7-H4-/- pregnant mice to infected B7-H4-/- pregnant mice was used to examine the effect of B7-H4 on adverse pregnancy outcomes induced by T. gondii infection. RESULTS The results illustrated that B7-H4-/- pregnant mice infected by T. gondii had poorer pregnancy outcomes than their wild-type counterparts. The expression of B7-H4 on dMφ significantly decreased after T. gondii infection, which resulted in the polarization of dMφ from the M2 toward the M1 phenotype by changing the expression of membrane molecules (CD80, CD86, CD163, CD206), synthesis of arginine metabolic enzymes (Arg-1, iNOS) and production of cytokines (IL-10, TNF-α) production. Also, we found that the B7-H4 downregulation after T. gondii infection increased iNOS and TNF-α expression mediated through the JAK2/STAT1 signaling pathway. In addition, adoptive transfer of dMφ from a WT pregnant mouse donor rather than from a B7-H4-/- pregnant mouse donor was able to improve adverse pregnancy outcomes induced by T. gondii infection. CONCLUSIONS The results demonstrated that the downregulation of B7-H4 induced by T. gondii infection led to the dysfunction of decidual macrophages and contributed to abnormal pregnancy outcomes. Moreover, adoptive transfer of B7-H4+ dMφ could improve adverse pregnancy outcomes induced by T. gondii infection.

Prognostic values of B7-H3, B7-H4, and HHLA2 expression in human pancreatic cancer tissues based on mIHC and spatial distribution analysis. Pathol Res Pract 2022; 234:153911. [PMID: 35489125 DOI: 10.1016/j.prp.2022.153911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 04/10/2022] [Accepted: 04/22/2022] [Indexed: 11/21/2022]
Abstract
BACKGROUND Pancreatic cancer (PC) is one of the most malignant solid tumors and its 5-year survival rate remains poor. Although immunotherapy has achieved certain therapeutic efficacy in some clinical trials, such treatment still shows low responses and overall remission rate. Therefore, it is urgently necessary to dissect the tumor microenvironment and optimize the immunotherapeutic strategies against this malignancy. METHODS Using the multi-color immunohistochemistry assay, we investigated the expressions of B7-H3, B7-H4, HHLA2, CD8, and CD68 in 63 cases of PC tissues in a tissue microarray. Moreover, we analyzed immunolocalization features, clinical associations and prognostic values of these molecules. RESULTS The expressions of B7-H3, B7-H4, and HHLA2 could be detected in cytokeratin staining positive (CK+) cancer epithelial cells, CD68+tumor-associated macrophages (TAMs), and even other cells defined as CK-CD8-CD68-. Higher expression of B7-H3 in tumor cells could predict a better survival of the PC patients. A positive correlation was found between the expressions of B7-H3 and HHLA2 in tumor cells, while there was a negative correlation between the expressions of B7-H4 and HHLA2 in tumor cells. A positive correlation was found between the expressions of B7-H3 and B7-H4 or HHLA2 in CD68+TAMs, but not B7-H4 and HHLA2. Tumor-infiltrating CD8+T cells in combination with CD68+TAMs could serve as an important predictor for the postoperative prognosis of PC patients. Higher expression of B7-H3, or HHLA2 in CD68+TAMs could serve as an important predictor for poorer prognosis of PC patients. Patients with B7-H3lowB7-H4low, B7-H3lowHHLA2low, or B7-H4lowHHLA2low on CD68+TAMs could have a better postoperative prognosis compared with the other sub-populations in the combinational analysis. CONCLUSIONS Taken together, our study indicated variable expressions and prognostic values of B7-H3, B7-H4, and HHLA2, in human PC tissues, and demonstrated that these co-stimulator molecules expressed by CD68+TAMs could be used as important bio-markers for the prognostic prediction of PC patients. Moreover, these results supported that the evaluation of these markers could be used as essential candidate targets for immunotherapy against PC.

Abstract
Tumor immunotherapy has attracted more and more attention nowadays, and multiple clinical trials have confirmed its effect in a variety of solid tumors. Immune checkpoint inhibitors (ICIs), cancer vaccines, adoptive cell transfer (ACT), and lymphocyte-promoting cytokines are the main immunotherapy methods. Endometrial cancer (EC) is one of the most frequent tumors in women and the prognosis of recurrent or metastatic EC is poor. Since molecular classification has been applied to EC, immunotherapy for different EC subtypes (especially POLE and MSI-H) has gradually attracted attention. In this review, we focus on the expression and molecular basis of the main biomarkers in the immunotherapy of EC firstly, as well as their clinical application significance and limitations. Blocking tumor immune checkpoints is one of the most effective strategies for cancer treatment in recent years, and has now become the focus in the field of tumor research and treatment. We summarized clinical date of planned and ongoing clinical trials and introduced other common immunotherapy methods in EC, such as cancer vaccine and ACT. Hormone aberrations, metabolic syndrome (MetS) and p53 mutant and that affect the immunotherapy of endometrial cancer will also be discussed in this review.

Abstract
BACKGROUND In order to find new immune targets for lung cancer with different EGFR mutant status, we describe differential expression profiles of checkpoint molecules of the new discovery B7 family member to find new immune targets for lung cancer with different EGFR statuses. METHODS We performed immunohistochemistry with antibodies of B7-H3, B7-H4, VISTA, B7-H6, HHLA2, IDO-1, PD-L1 and CD8 in lung adenocarcinoma tissues constructed from 372 cases in the discovery cohort and 231 cases in the validation set. The differential expression profiles of these indices in EGFR mutant and wild-type lung adenocarcinoma was described and compared. RESULTS In the discovery cohort, the median IHC scores of B7-H4 and HHLA2 for the EGFR mutant group were significantly higher than those in the wild-type group (median score [interquartile range], mutant vs. wild type: 3.250 [0-7.000] vs. 5.000 [1.000-7.000], P = 0.045 for B7-H4; 8.000 [6.000-10.500] vs. 7.000 [5.000-8.630] P = 0.003 for HHLA2). Meanwhile, the median IHC scores of IDO-1 and PD-L1 in the wild-type group were significantly higher than those in the mutant group (median score [interquartile range], mutant vs. wild type: 1.000 [0-5.000] vs. 3.000 [0-8.500], P = 0.000 for IDO-1; 0 [0-3.500] vs. 3.000 [0-6.000], P = 0.000 for PD-L1). Results above was confirmed in the discovery cohort. The increased CD8 and decreased HHLA2 expression levels were associated with long disease-free survival in lung adenocarcinoma (P = 0.000 for CD8 expression and P = 0.004 for HHLA2 expression). CONCLUSIONS B7-H4 and HHLA2 are promising immune targets for lung adenocarcinoma, especially for patients with EGFR mutation.

B7-H4 is Inversely Correlated With T-Cell Infiltration in Clear Cell but Not Serous or Endometrioid Ovarian Cancer. Appl Immunohistochem Mol Morphol 2020; 27:515-522. [PMID: 29189263 DOI: 10.1097/pai.0000000000000608] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/16/2022]
Abstract
B7-H4, a tumor-associated cell surface protein, is expressed in endometrioid (EM), serous (SE), and clear cell (CC) ovarian carcinomas. Prior in vitro studies from other groups indicated that elevated B7-H4 expression by tumor cells blocks T-cell activation; therefore, it had been postulated to play a role in shielding cancer cells from immune surveillance and averting apoptotic programs. To test the validity of these hypotheses, the present study was designed to compare the immunohistochemical staining intensity of B7-H4 in tumor cells of ovarian cancers with the number of tumor-infiltrating T cells and macrophages and with the levels of caspase-3 staining in apoptotic debris. Serial tissue sections from EM, SE, and CC carcinomas were analyzed across representative cross-sections of tumor resection specimens, demonstrating different levels of B7-H4 expression, highest in CC cancers. B7-H4 staining in CC tissue sections was significantly correlated with the number of CD3, CD4, and CD8 tumor-infiltrating T cells and with the number of CD14 tumor-infiltrating macrophages, but was not significantly related to caspase-3 staining. These results support the concept that high levels of B7-H4 expression are inversely correlated with tumor T-cell infiltration and with CD14-labeled macrophages but not caspase-3 expression in CC carcinomas. We did not, however, find clear evidence of a relationship between the lower levels of B7-H4 seen in EM and SE carcinomas and T cell or macrophage infiltration. Thus, high levels of B7-H4, as seen in CC carcinomas, is associated with decreased tumor infiltration by T cells and macrophages but the lower levels of expression, as observed in EM and SE carcinomas, appear less likely to play an effective role in protection from immune surveillance. Furthermore, we found no evidence of a correlation between B7-H4 expression and apoptosis. These findings highlight the importance of further investigation of B7-H4 as an immunomodulatory protein, to support the development of novel therapeutic interventions for improved efficacy of treatments for CC carcinoma.

Abstract
Background Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐associated mortality worldwide of which lung adenocarcinoma (LUAD) is the most common. The identification of oncogenes and effective drug targets is the key to individualized LUAD treatment. Actin‐like protein 8 (ACTL8), a member of the cancer/testis antigen family, is associated with tumor growth and patient prognosis in various types of cancer. However, whether ACTL8 is involved in the development of LUAD remains unknown. The aim of the present study was to demonstrate the role of ACTL8 in human LUAD cells. Methods The expression of ACTL8 in LUAD tissues and cell lines was assessed using immunohistochemistry and western blotting. Additionally, plasmids expressing ACTL8‐specific short hairpin RNAs were used to generate lentiviruses which were subsequently used to infect A549 and NCI‐H1975 human LUAD cells. Cell proliferation, migration, invasion and apoptosis, as well as cell cycle progression and the expression of protein markers of epithelial to mesenchymal transition were investigated. A549 cell tumor growth in nude mice was also examined. Results The results showed that ACTL8 was highly expressed in A549 and NCI‐H1975 LUAD cell lines. Additionally, ACTL8‐knockdown inhibited proliferation, colony formation, cell cycle progression, migration and invasion, and increased apoptosis in both cell lines. Furthermore, in vivo experiments in nude mice revealed that ACTL8‐knockdown inhibited A549 cell tumor growth. Conclusion These results suggest that ACTL8 serves an oncogenic role in human LUAD cells, and that ACTL8 may represent a potential therapeutic target for LUAD. Key points Our results suggest that ACTL8 serves an oncogenic role in human LUAD cells, and that ACTL8 may represent a potential therapeutic target for LUAD.

Abstract
The coinhibitory molecule B7-H4, an important member of the B7 family, is abnormally expressed in tumors, inflammation and autoimmune diseases. B7-H4 negatively regulates T cell immune response and promotes immune escape by inhibiting the proliferation, cytokine secretion, and cell cycle of T cells. Moreover, B7-H4 plays an extremely important role in tumorigenesis and tumor development including cell proliferation, invasion, metastasis, anti-apoptosis, etc. In addition, B7-H4 has the other biological functions, such as protection against type 1 diabetes (T1D) and islet cell transplantation. Therefore, B7-H4 has been identified as a novel marker or a therapeutic target for the treatment of tumors, inflammation, autoimmune diseases, and organ transplantation. Here, we summarized the expression profiles, physiological and pathological functions, and regulatory mechanisms of B7-H4, the signaling pathways involved, as well as B7-H4-based immunotherapy.

Abstract
Clinical practice in radiology and pathology requires professional expertise and many years of training to visually evaluate and interpret abnormal phenotypic features in medical images and tissue sections to generate diagnoses that guide patient management and treatment. Recent advances in digital image analysis methods and machine learning have led to significant interest in extracting additional information from medical and digital whole-slide images in radiology and pathology, respectively. This has led to significant interest and research in radiomics and pathomics to correlate phenotypic features of disease with image analytics in order to identify image-based biomarkers. The expanding role of big data in radiology and pathology parallels the development and role of immunohistochemistry (IHC) in the daily practice of pathology. IHC methods were initially developed to provide additional information to help classify tumors and then transformed into an indispensable tool to guide treatment in many types of cancer. IHC markers are used in daily practice to identify specific types of cells and highlight their distributions in tissues in order to distinguish benign from neoplastic cells, determine tumor origin, subclassify neoplasms, and support and confirm diagnoses. In this regard, radiomics, pathomics, and IHC methods are very similar since they enable the extraction of image-based features to characterize various properties of diseases. Due to the dramatic advancements in recent radiomics research, we provide a brief overview of the role of established and emerging IHC biomarkers in various tumor types that have been correlated with radiologic biomarkers to improve diagnostic accuracy, predict prognosis, guide patient management, and select treatment strategies.

Abstract
Immune checkpoint proteins (ICPs) are regulators of immune system. The ICP dysregulation silences the host immune response to cancer-specific antigens, contributing to the occurrence and progress of various cancers. MiRNAs are regulatory molecules and function in mRNA silencing and post-transcriptional regulation of gene expression. MiRNAs that modulate the immunity via ICPs have received increasing attention. Many studies have shown that the expressions of ICPs are directly or indirectly repressed by miRNAs in multiple types of cancers. MiRNAs are also subject to regulation by ICPs. In this review, recent studies of the relationship between miRNAs and ICPs (including the PD-1, PD-L1, CTLA-4, ICOS, B7-1, B7-2, B7-H2, B7-H3, CD27, CD70, CD40, and CD40L) in cancer immune escape are comprehensively discussed, which provide critical detailed mechanistic insights into the functions of the miRNA-ICP axes and their effects on immune escape, and will be beneficial for the potential applications of immune checkpoint therapy and miRNA-based guidance for personalized medicine as well as for predicting the prognosis.

Characterization of immune regulatory molecules B7-H4 and PD-L1 in low and high grade endometrial tumors. Gynecol Oncol 2017; 145:446-452. [PMID: 28347512 DOI: 10.1016/j.ygyno.2017.03.006] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2016] [Revised: 03/06/2017] [Accepted: 03/10/2017] [Indexed: 01/06/2023]
Abstract
BACKGROUND The objective of this investigation was to characterize the expression landscape of immune regulatory molecules programmed death-ligand-1 (PD-L1, B7-H1) and B7-H4 in a cohort of endometrial tumors across the spectrum of grade and histology. MATERIALS AND METHODS With institutional review board approval, 70 endometrial tumors from patients with known clinical outcomes were identified representing a spectrum of grade and histology. Immunohistochemistry (IHC) was performed for PD-L1 and B7-H4 and scored. Microsatellite instability (MSI) status was assessed for endometrioid tumors using the institutional IHC assay for expression of the mismatch repair (MMR) genes, MLH1, MSH2, MSH6 and PMS2. RNA sequencing data from the Cancer Genome Atlas was queried for expression levels of CD274 (PD-L1 protein) and VTCN1 (B7-H4) across molecular subtypes of endometrial carcinoma and were correlated with a T cell infiltration index. RESULTS We identified 40 low grade endometrioid tumors and a cohort of 30 high grade tumors. PD-L1 expression was observed in both high and low grade endometrial tumors (56% vs 35%, p=0.07). In the low grade tumors, PD-L1 expression was associated with MSI status (p<0.01). The high grade cohort had similar rates of PD-L1 expression compared to low grade MSI tumor (56% and 62% respectively), and both were distinct from low grade MSS tumors (22%, p<0.05). High (3+) B7-H4 positive cells were observed in both high and low grade carcinomas (33% and 31% respectively). RNA profiling data from confirmed highest CD274 expression in POLE and MSI tumors that was linearly correlated with T cell infiltration, while VTCN1 expression appeared consistent across molecular subtypes. CONCLUSIONS While PD-L1 expression correlated with MSI and high grade tumors, B7-H4 expression was independent of grade, histology and immune cell infiltration. The development and testing of multi-agent therapeutics targeting PD-L1 and B7-H4 may be a novel strategy for endometrial tumors.
