Abstract
There are numerous macrophages and dendritic cells in lymph nodes (LNs). Recent studies have highlighted that sinus macrophages (SMs) in LNs possess antigen-presenting capabilities and are related to anti-cancer immune responses. In this study, we assessed the distribution of SMs in mesenteric LNs removed during surgery for colorectal cancer. A marked reduction of SMs was noted in elderly patients, particularly those over 80 years old. We observed a disappearance of CD169-positive cells in LNs where SMs were reduced. In silico analysis of publicly available single-cell RNA sequencing data from LNs revealed that CD169-positive macrophages express numerous genes associated with antigen presentation and lymphocyte proliferation, similar to dendritic cells' functions. In conclusion, our study demonstrates that SMs, potentially crucial for immune activation, diminish in the LNs of elderly patients. This reduction of SMs may contribute to the immune dysfunction observed in the elderly.

Abstract
The role of sinus macrophages (SMs) in anticancer immune responses has received considerable interest in recent years, but the types of molecules that are expressed in human SMs have not yet been clarified in detail. We therefore sought to identify dendritic cell (DC)- or macrophage-related molecules in SMs in human lymph nodes (LNs). SMs are strongly positive for Iba-1, CD163, CD169, and CD209. CD169 (clone SP216) reacted with almost all SMs, mainly in the cell surface membrane, while CD169 (clone HSn 7D2) reacted with a subpopulation of SMs, mainly in the cytoplasm, with a significant increase observed after IFN-α stimulation. The immunoreactivity of clone HSn 7D2 was markedly reduced after transfection with small interfering RNA against CD169, while that of clone SP216 was slightly reduced. The induction of CCL8 and CXCL10 messenger RNA (mRNA) expression by IFN-α was confirmed using cultured macrophages and RT-qPCR, but fluorescence in situ hybridization did not detect CCL8 and CXCL10 mRNA expression in SMs. Single-cell RNA sequence data of LNs indicated that the highest level of CXCL10 gene expression occurred in monocytes. In conclusion, we found that CD209, also known as DC-related molecule, was expressed in human SMs. The heterogeneity observed in CD169 reacted with cone HSn 7D2 and SP216 was potentially due to the modification of CD169 protein by IFN stimulation. Further, no expression of CXCL10 mRNA in SMs suggested that SMs might be resident macrophages.

Abstract
AIMS Mismatch-repair deficiency and microsatellite instability-high (dMMR/MSI-H) colorectal cancer (CRC) is treated with programmed death (PD)-1 antibody regardless of PD-ligand (L)1 expression in tumor cells. We previously found that abundant CD169+ macrophages in regional lymph node (RLN) sinuses and CD8+ tumor-infiltrating lymphocytes (TILs) positively correlated in CRC and were associated with a favorable prognosis. However, associations between dMMR/MSI-H CRC and CD8+ TILs or prognoses vary among studies. In this study, we attempted to compare the association between MMR status, CD169+ macrophages in RLNs, CD8+ TILs, PD-L1 scores, and prognoses in CRC. METHODS AND RESULTS We immunostained 83 surgically resected CRC tumors that we previously analyzed for MMR proteins, and identified 9 that were dMMR. The number of CD169+ macrophages in RLNs and CD8+ TILs significantly correlated with overall survival, whereas MMR status did not. The number of cells positive for the TIL markers CD3, CD4, CD8, and TIA-1, and macrophage markers CD68 and CD169 in RLNs did not significantly differ between groups according to MMR status. Furthermore, combined positive scores (CPS) for PD-L1 expression in five of nine dMMR CRCs were all <1. We found that dMMR in CRC did not correlate with numbers of CD169+ macrophages in RLNs or CD8+ TILs. CONCLUSIONS CRC with CD169+ macrophages in RLNs and abundant CD8+ TILs indicates a better prognosis and it should be immunologically classified as a different antitumor group from dMMR CRC.

Abstract
Recent progress in anti-tumor therapy has revealed the significance of anti-tumor immune responses in tumor progression and clinical course in several kinds of malignant tumors. The draining lymph node is an important immune system component that contains a number of antigen-presenting cells, which induce rapid immune responses to foreign antigens. Current studies have shown that higher expression of CD169 on lymph node sinus macrophages is associated with the induction of anti-tumor immunity. In the present study, we searched for natural compounds that regulate the CD169-positive phenotype in macrophages to identify potential new anti-cancer agents targeting macrophage activation. Among 50 natural compounds, aculeatiside A, naringin, and onionin A significantly induced the CD169-positive phenotype in human monocyte-derived macrophages. These compounds also induced CD169 overexpression and secretion of inflammatory cytokines, including interleukin (IL)-1β and IL-12, in murine macrophages. Subcutaneous injection of aculeatiside A and naringin enhanced mRNA expression of IL-1β, IL12, and CD169 in regional lymph nodes in mice. These findings suggest aculeatiside A and naringin may enhance anti-tumor immune responses by inducing CD169-positive macrophages in lymph nodes.

Abstract
The lymph node (LN) is an important immune system in which a number of antigen‐presenting cells are present that induce rapid immune responses to foreign antigens. While a great number of macrophages exist in lymph nodes, recent studies using animal models have shown that lymph node sinus macrophages are associated with the induction of anti‐tumor immunity, playing a significant role in host immune responses against tumor cells. In colorectal tumor, malignant melanoma, and endometrial tumor, it was shown that a high density of CD169‐positive macrophages in the LN sinus was a predictive factor for better clinical prognosis. The observations that the density of CD169‐positive macrophages in the LN sinus was positively associated with the density of infiltrating T or NK cells in tumor tissues, indicates the significance of CD169‐positive macrophages in anti‐tumor immune reactions of tumor patients. Moreover, antigen delivery targeting LN macrophages is also considered to be promising approach for vaccination. In this article, we have summarized the significance of CD169‐positive LN macrophages in anti‐tumor immunity.

Abstract
Lymph node (LN) macrophages play critical roles in anti-tumor immunity, which develops via the activation of cytotoxic T cells (CTL) and NK cells. The present study aims to determine the prognostic significance of CD169(+) LN macrophages in patients with endometrial carcinoma (EC). The number of CD169(+) cells or the CD169(+) -to-CD68(+) macrophage ratio in regional LN (RLN), and the number of CD8(+) CTL or CD57(+) NK cells in tumor tissues were investigated by immunohistochemistry in paraffin-embedded tissue samples from 79 patients with EC. A high density of CD169(+) cells in the RLN of patients with EC was correlated with an early clinical stage or no LN metastasis. A high number of CD169(+) cells and a high CD169(+) -to-CD68(+) macrophage ratio were significantly associated with longer overall survival in EC. We also found that the density of CD169(+) macrophages was positively correlated with the number of CD8(+) CTL and CD57(+) NK cells that infiltrated into tumor tissues. A high density of CD57(+) cells in EC tissues was associated with a better prognosis, while a high density of CD8(+) cells was not linked to an altered prognosis. The present study showed that the density of CD169(+) macrophages in RLN was associated with an improved prognosis in EC patients. CD169(+) macrophages in RLN might represent a useful marker for assessing clinical prognoses and monitoring anti-tumor immunity in patients with EC.
