Pediatr Res 2024:10.1038/s41390-024-03181-9. [PMID: 38710942 DOI: 10.1038/s41390-024-03181-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 01/11/2024] [Accepted: 03/01/2024] [Indexed: 05/08/2024]
Abstract
BACKGROUND This study aims to investigate the role of endoplasmic reticulum stress (ER stress) in human dermal lymphatic endothelial cells (HDLECs) and lymphatic malformations (LMs) and its relationship with aerobic glycolysis and inflammation. METHODS The proliferation and apoptosis of HDLECs were examined with lipopolysaccharide (LPS) treatment. ER stress-associated proteins and glycolysis-related markers were detected by western blot. Glycolysis indexes were detected by seahorse analysis and lactic acid production assay kits. Immunohistochemistry was used to reveal the ER stress state of lymphatic endothelial cells (LECs) in LMs. RESULTS LPS induced ER stress in HDLECs but did not trigger detectable apoptosis. Intriguingly, LPS-treated HDLECs also showed increased glycolysis flux. Knockdown of Hexokinase 2, a key enzyme for aerobic glycolysis, significantly inhibited the ability of HDLECs to resist ER stress-induced apoptosis. Moreover, compared to normal skin, glucose-regulated protein 78 (GRP78/BIP), and phosphorylation protein kinase R-like kinase (p-PERK), two key ER stress-associated markers, were upregulated in LECs of LMs, which was correlated with the inflected state. In addition, excessively activated ER stress inhibited the progression of LMs in rat models. CONCLUSIONS These data indicate that glycolysis could rescue activated ER stress in HDLECs, which is required for the accelerated development of LMs. IMPACT Inflammation enhances both ER stress and glycolysis in LECs while glycolysis is required to attenuate the pro-apoptotic effect of ER stress. Endoplasmic reticulum (ER) stress is activated in lymphatic endothelial cells (LECs) of LMs, especially in inflammatory condition. The expression of ER stress-related proteins is increased in LMs and correlated with Hexokinase 2 expression. Pharmacological activation of ER stress suppresses the formation of LM lesions in the rat model. ER stress may be a promising and effective therapeutic target for the treatment of LMs.

Abstract
Tertiary lymphoid structures (TLS) are clusters of immune cells that resemble and function similarly to secondary lymphoid organs (SLOs). While TLS is generally associated with an anti-tumour immune response in most cancer types, it has also been observed to act as a pro-tumour immune response. The heterogeneity of TLS function is largely determined by the composition of tumour-infiltrating lymphocytes (TILs) and the balance of cell subsets within the tumour-associated TLS (TA-TLS). TA-TLS of varying maturity, density, and location may have opposing effects on tumour immunity. Higher maturity and/or higher density TLS are often associated with favorable clinical outcomes and immunotherapeutic response, mainly due to crosstalk between different proportions of immune cell subpopulations in TA-TLS. Therefore, TLS can be used as a marker to predict the efficacy of immunotherapy in immune checkpoint blockade (ICB). Developing efficient imaging and induction methods to study TA-TLS is crucial for enhancing anti-tumour immunity. The integration of imaging techniques with biological materials, including nanoprobes and hydrogels, alongside artificial intelligence (AI), enables non-invasive in vivo visualization of TLS. In this review, we explore the dynamic interactions among T and B cell subpopulations of varying phenotypes that contribute to the structural and functional diversity of TLS, examining both existing and emerging techniques for TLS imaging and induction, focusing on cancer immunotherapies and biomaterials. We also highlight novel therapeutic approaches of TLS that are being explored with the aim of increasing ICB treatment efficacy and predicting prognosis.

Abstract
The lymphatic vascular system is gaining recognition for its multifaceted role and broad pathological significance. Once perceived as a mere conduit for interstitial fluid and immune cell transport, recent research has unveiled its active involvement in critical physiological processes and common diseases, including inflammation, autoimmune diseases, and atherosclerosis. Consequently, abnormal development or functionality of lymphatic vessels can result in serious health complications. Here, we discuss lymphatic malformations (LMs), which are localized lesions that manifest as fluid-filled cysts or extensive infiltrative lymphatic vessel overgrowth, often associated with debilitating, even life-threatening, consequences. Genetic causes of LMs have been uncovered, and several promising drug-based therapies are currently under investigation and will be discussed.

Abstract
The lymphatic system, crucial for tissue fluid balance and immune surveillance, can be severely impacted by disorders that hinder its activities. Lymphatic malformations (LMs) are caused by fluid accumulation in tissues owing to defects in lymphatic channel formation, the obstruction of lymphatic vessels or injury to lymphatic tissues. Somatic mutations, varying in symptoms based on lesions' location and size, provide insights into their molecular pathogenesis by identifying LMs' genetic causes. In this review, we collected the most recent findings about the role of genetic and inflammatory biomarkers in LMs that control the formation of these malformations. A thorough evaluation of the literature from 2000 to the present was conducted using the PubMed and Google Scholar databases. Although it is obvious that the vascular endothelial growth factor receptor 3 mutation accounts for a significant proportion of LM patients, several mutations in other genes thought to be linked to LM have also been discovered. Also, inflammatory mediators like interleukin-6, interleukin-8, tumor necrosis factor-alpha and mammalian target of rapamycin are the most commonly associated biomarkers with LM. Understanding the mutations and genes expression responsible for the abnormalities in lymphatic endothelial cells could lead to novel therapeutic strategies based on molecular pathways.

Life Sci 2021; 268:118989. [PMID: 33417962 DOI: 10.1016/j.lfs.2020.118989] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 12/22/2020] [Accepted: 12/30/2020] [Indexed: 12/26/2022]
Abstract
AIMS The imbalance of M1/M2 macrophage ratio promotes the occurrence of diabetic cardiomyopathy (DCM), but the precise mechanisms are not fully understood. The aim of this study was to investigate whether miR-471-3p/silent information regulator 1 (SIRT1) pathway is involved in the macrophage polarization during the development of DCM. METHODS Immunohistochemical staining was used to detect M1 and M2 macrophages infiltration in the heart tissue. Flow cytometry was used to detect the proportion of M1 and M2 macrophages. Expression of miR-471-3p was quantified by real time quantitative-PCR. Transfection of miRNA inhibitor into RAW264.7 cells was performed to investigate the underlying mechanisms. Bioinformatics methods and western blotting were used to explore the target gene of miR-471-3p and further confirmed by dual luciferase reporter assay. KEY FINDINGS We observed that M1 macrophages infiltration in the heart of tissue in DCM while M2 type was decreased. M1/M2 ratio was increased significantly in bone marrow-derived macrophages (BMDMs) from db/db mice and in RAW264.7 cells treated with advanced glycation end products (AGEs). Meanwhile, miR-471-3p was significantly upregulated in RAW264.7 cells induced by AGEs and inhibition of miR-471-3p could reduce the inflammatory polarization of macrophages. Bioinformatics analysis identified SIRT1 as a target of miR-471-3p. Both dual luciferase reporter assay and western blotting verified that miR-471-3p negatively regulated SIRT1 expression. SIRT1 agonist resveratrol could downregulate the increased proportion of M1 macrophages induced by AGEs. CONCLUSION Our results indicated that the development of DCM was related to AGEs-induced macrophage polarized to M1 type through a mechanism involving the miR-471-3p/SIRT1 pathway.

Abstract
Lymphangioma is a common type of congenital vascular disease in children with a broad spectrum of clinical manifestations. The current classification of lymphangioma by International Society for the Study of Vascular Anomalies is largely based on the clinical manifestations and complications and is not sufficient for selection of therapeutic strategies and prognosis prediction. The clinical management and outcome of lymphangioma largely depend on the clinical classification and the location of the disease, ranging from spontaneous regression with no treatment to severe sequelae even with comprehensive treatment. Recently, rapid progression has been made toward elucidating the molecular pathology of lymphangioma and the development of treatments. Several signaling pathways have been revealed to be involved in the progression and development of lymphangioma, and specific inhibitors targeting these pathways have been investigated for clinical applications and clinical trials. Some drugs already currently in clinical use for other diseases were found to be effective for lymphangioma, although the mechanisms underlying the anti-tumor effects remain unclear. Molecular classification based on molecular pathology and investigation of the molecular mechanisms of current clinical drugs is the next step toward developing more effective individualized treatment of children with lymphangioma with reduced side effects.

Abstract
Metabolism plays a pivotal role in the formation of the lymphatic vasculature. Pyruvate kinase M2 (PKM2) is typically a metabolic marker of proliferating cells and maintains the growth of vascular endothelial cells. In this study, the potential status of PKM2 in lymphatic endothelial cells and the pathogenesis of lymphatic malformations (LMs) was investigated. The glycolysis index, including glucose uptake, ATP, and lactate production, stayed at a relatively high level in human dermal lymphatic endothelial cells (HDLECs) compared with human umbilical vein endothelial cells, whereas the inhibition of PKM2 by shikonin or PKM2 knockdown significantly suppressed glycolysis, migration, tubular formation, and invasion of HDLECs. Moreover, compared with lymphatic vessels in healthy skin, lymphatic vessels of LMs expressed PKM2 highly, and this expression correlated with infection of LMs. Meanwhile, the overexpression of PKM2 in HDLECs strengthened the proliferation, migration, tubular formation, and invasion of HDLECs. The findings from further experiments in a rat LM model support that targeting PKM2 by shikonin significantly impedes the progression of LMs, even in an infected LM rat model. Taken together, these results indicate that PKM2 plays a pivotal role in the activation of LECs and promotes the progression of LMs, whereas the inhibition of PKM2 can effectively suppress the pathogenesis of LM lesions in the rat model.

Abstract
Macrophage activation syndrome (MAS) is hyperinflammatory life-threatening syndrome, associated typically with high levels of serum ferritin. This is an iron storage protein including heavy (H) and light (L) subunits, categorized on their molecular weight. The H-/L subunits ratio may be different in tissues, depending on the specific tissue and pathophysiological status. In this study, we analysed the bone marrow (BM) biopsies of adult MAS patients to assess the presence of: (i) H-ferritin and L-ferritin; (ii) CD68+ /H-ferritin+ and CD68+ /L-ferritin+ ; and (iii) interleukin (IL)-1β, tumour necrosis factor (TNF) and interferon (IFN)-γ. We also explored possible correlations of these results with clinical data. H-ferritin, IL-1β, TNF and IFN-γ were increased significantly in MAS. Furthermore, an increased number of CD68+ /H-ferritin+ cells and an infiltrate of cells co-expressing H-ferritin and IL-12, suggesting an infiltrate of M1 macrophages, were observed. H-ferritin levels and CD68+ /H-ferritin+ cells were correlated with haematological involvement of the disease, serum ferritin and C-reactive protein. L-ferritin and CD68+ /L-ferritin+ cells did not correlate with these parameters. In conclusion, during MAS, H-ferritin, CD68+ /H-ferritin+ cells and proinflammatory cytokines were increased significantly in the BM inflammatory infiltrate, pointing out a possible vicious pathogenic loop. To date, H-ferritin and CD68+ /H-ferritin+ were associated significantly with haematological involvement of the disease, suggesting biomarkers assessing severity of clinical picture.

Abstract
Adult-onset Still's disease (AOSD) patients may show an evanescent salmon-pink erythema appearing during febrile attacks and reducing without fever. Some patients may experience this eruption for many weeks. During AOSD, exceptionally high serum levels of ferritin may be observed; it is an iron storage protein composed of 24 subunits, heavy (H) subunits and light (L) subunits. The ferritin enriched in L subunits (L-ferritin) and the ferritin enriched in H subunits (H-ferritin) may be observed in different tissues. In this work, we aimed to investigate the skin expression of both H-and L-ferritin and the number of macrophages expressing these molecules from AOSD patients with persistent cutaneous lesions. We observed an increased expression of H-ferritin in the skin, associated with an infiltrate in the biopsies obtained from persistent cutaneous lesions of AOSD patients. Furthermore, a positive correlation between H-ferritin skin levels as well as the number of CD68(+) /H-ferritin(+) cells and the multi-visceral involvement of the disease was observed. Our data showed an increased expression of H-ferritin in the skin of AOSD patients, associated with a strong infiltrate of CD68(+) /H-ferritin(+) cells. Furthermore, a correlation between the levels of H-ferritin as well as of the number of CD68(+) /H-ferritin(+) cells and the multi-visceral involvement of the disease was observed.

Breast cancers from black women exhibit higher numbers of immunosuppressive macrophages with proliferative activity and of crown-like structures associated with lower survival compared to non-black Latinas and Caucasians. Breast Cancer Res Treat 2016; 158:113-126. [PMID: 27283835 DOI: 10.1007/s10549-016-3847-3] [Citation(s) in RCA: 77] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2016] [Accepted: 05/27/2016] [Indexed: 12/16/2022]
Abstract
Racial disparities in breast cancer incidence and outcome are a major health care challenge. Patients in the black race group more likely present with an early onset and more aggressive disease. The occurrence of high numbers of macrophages is associated with tumor progression and poor prognosis in solid malignancies. Macrophages are observed in adipose tissues surrounding dead adipocytes in "crown-like structures" (CLS). Here we investigated whether the numbers of CD163+ tumor-associated macrophages (TAMs) and/or CD163+ CLS are associated with patient survival and whether there are significant differences across blacks, non-black Latinas, and Caucasians. Our findings confirm that race is statistically significantly associated with the numbers of TAMs and CLS in breast cancer, and demonstrate that the highest numbers of CD163+ TAM/CLS are found in black breast cancer patients. Our results reveal that the density of CD206 (M2) macrophages is a significant predictor of progression-free survival univariately and is also significant after adjusting for race and for HER2, respectively. We examined whether the high numbers of TAMs detected in tumors from black women were associated with macrophage proliferation, using the Ki-67 nuclear proliferation marker. Our results reveal that TAMs actively divide when in contact with tumor cells. There is a higher ratio of proliferating macrophages in tumors from black patients. These findings suggest that interventions based on targeting TAMs may not only benefit breast cancer patients in general but also serve as an approach to remedy racial disparity resulting in better prognosis patients from minority racial groups.
