FOXC2 controls adult lymphatic endothelial specialization, function, and gut lymphatic barrier preventing multiorgan failure

Mauro Delorenzi, Alexis Rapin, Dominique Velin

The mechanisms maintaining adult lymphatic vascular specialization throughout life and their role in coordinating inter-organ communication to sustain homeostasis remain elusive. We report that inactivation of the mechanosensitive transcription factor Foxc ...

Adjuvant-free immunization with infective filarial larvae as lymphatic homing antigen carriers

Melody Swartz, Alexandre de Titta, Esra Güç, David Scott Wilson, Marcela Rincón-Restrepo, Sachiko Hirosue

Controlled infection with intestinal nematodes has therapeutic potential for preventing the symptoms of allergic and autoimmune diseases. Here, we engineered larvae of the filarial nematode Litomosoides sigmodontis as a vaccine strategy to induce adaptive ...

Experimental Drainage Device to Reduce Lymphoedema in a Rat Model

Nikolaos Stergiopoulos, Melody Swartz, Marco Pisano, Valentina Triacca

Objective: Despite recent advances in pharmacological research and microsurgery, lymphoedema remains an incurable disease that deeply affects quality of life. There is an urgent need for innovative approaches to restore continuous lymph flow in affected ti ...

Inherent biomechanical traits enable infective filariae to disseminate through collecting lymphatic vessels

Melody Swartz, Marco Pisano

Filariases are diseases caused by arthropod-borne filaria nematodes. The related pathologies depend on the location of the infective larvae when their migration, the asymptomatic and least studied phase of the disease, comes to an end. To determine factors ...

Lymphatic vessel density is associated with CD8(+) T cell infiltration and immunosuppressive factors in human melanoma

Melody Swartz, Manuel Andreas Fankhauser, Timothy Murray

Increased density of tumor-associated lymphatic vessels correlates with poor patient survival in melanoma and other cancers, yet lymphatic drainage is essential for initiating an immune response. Here we asked whether and how lymphatic vessel density (LVD) ...

Multiple roles of lymphatic vessels in peripheral lymph node development

The mammalian lymphatic system consists of strategically located lymph nodes (LNs) embedded into a lymphatic vascular network. Mechanisms underlying development of this highly organized system are not fully understood. Using highresolution imaging, we show ...

Elucidating the role of lymphatic vessels within the tumor microenvironment of breast cancer

Ingrid Maria van Mier

Breast cancer is the most common cancer in women worldwide, with an estimated 1.7 million newly diagnosed cases in 2012. Despite the many clinical manifestations, metastatic disease is the main cause of death, and is responsible for 90% of all breast cance ...

Transcellular Pathways in Lymphatic Endothelial Cells Regulate Changes in Solute Transport by Fluid Stress

Melody Swartz, Marco Pisano, Esra Güç, Valentina Triacca

Rationale: The transport of interstitial fluid and solutes into lymphatic vessels is important for maintaining interstitial homeostasis and delivering antigens and soluble factors to the lymph node for immune surveillance. Transendothelial transport across ...

Interactions between fibroblastic reticular cells and B cells promote mesenteric lymph node lymphangiogenesis

Nicola Harris, Lalit Kumar Dubey

Lymphatic growth (lymphangiogenesis) within lymph nodes functions to promote dendritic cell entry and effector lymphocyte egress in response to infection or inflammation. Here we demonstrate a crucial role for lymphotoxin-beta receptor (LT beta R) signalin ...

Exploiting lymphatic vessels for immunomodulation: Rationale, opportunities, and challenges

Melody Swartz, Lambert Charles François Potin

Lymphatic vessels are the primary route of communication from peripheral tissues to the immune system; as such, they represent an important component of local immunity. In addition to their transport functions, new immunomodulatory roles for lymphatic vess ...

Medical fluid drainage system

Marco Pisano, Valentina Triacca

A medical fluid drainage system which may be advantageously used to actively absorb excess fluid from an interstitium in a living host and to transport it from an inlet member 1 in a non edematous body part out of an outlet member 4 via pumps (5, 6, 7) bui ...

Lymphatic vessels regulate immune microenvironments in human and murine melanoma

Melody Swartz, Manuel Andreas Fankhauser

Lymphatic remodeling in tumor microenvironments correlates with progression and metastasis, and local lymphatic vessels play complex and poorly understood roles in tumor immunity. Tumor lymphangiogenesis is associated with increased immune suppression, yet ...

Investigation of cell death mechanisms in human lymphatic endothelial cells undergoing photodynamic therapy

Background: Photodynamic therapy (PDT) has been shown to induce ablation and functional occlusion of tumor-associated lymphatic vessels. However, direct effects of PDT on lymphatic endothelial cells (LECs) have not been studied so far. The aim of this stud ...

FOXC2 and fluid shear stress stabilize postnatal lymphatic vasculature

Nadine Fournier, Mauro Delorenzi

Biomechanical forces, such as fluid shear stress, govern multiple aspects of endothelial cell biology. In blood vessels, disturbed flow is associated with vascular diseases, such as atherosclerosis, and promotes endothelial cell proliferation and apoptosis ...

Collecting Lymphatic Vessel Permeability Facilitates Adipose Tissue Inflammation and Distribution of Antigen to Lymph Node-Homing Adipose Tissue Dendritic Cells

Melody Swartz, Wei Wang

Collecting lymphatic vessels (CLVs), surrounded by fat and endowed with contractile muscle and valves, transport lymph from tissues after it is absorbed into lymphatic capillaries. CLVs are not known to participate in immune responses. In this study, we ob ...

Parasite Proximity Drives the Expansion of Regulatory T Cells in Peyer's Patches following Intestinal Helminth Infection

Nicola Harris, Beatrice Volpe, Julia Esser-von Bieren, Mario Michael Zaiss, Lalit Kumar Dubey, Ilaria Mosconi, Luc Xavier Marie Lebon

Helminth infections are typically chronic in nature; however, the exact molecular mechanisms by which these parasites promote or thwart host immunity remain unclear. Worm expulsion requires the differentiation of CD4(+) T cells into Th2 cells, while regula ...

Optimization and regeneration kinetics of lymphatic-specific photodynamic therapy in the mouse dermis

Melody Swartz, Patrycja Nowak-Sliwinska

Lymphatic vessels transport fluid, antigens, and immune cells to the lymph nodes to orchestrate adaptive immunity and maintain peripheral tolerance. Lymphangiogenesis has been associated with inflammation, cancer metastasis, autoimmunity, tolerance and tra ...

Immunomodulatory Roles of Lymphatic Vessels in Cancer Progression

Melody Swartz

Lymphatic vessels in the tumor microenvironment are known to foster tumor metastasis in many cancers, and they can undergo activation, hyperplasia, and lymphangiogenesis in the tumor microenvironment and in the tumor-draining lymph node. The mechanism unde ...

Lymphatic vasculature mediates macrophage reverse cholesterol transport in mice

Melody Swartz

Reverse cholesterol transport (RCT) refers to the mobilization of cholesterol on HDL particles (HDL-C) from extravascular tissues to plasma, ultimately for fecal excretion. Little is known about how HDL-C leaves peripheral tissues to reach plasma. We first ...
