BCG hydrogel promotes CTSS-mediated antigen processing and presentation, thereby suppressing metastasis and prolonging survival in melanoma

Background The use of intralesional Mycobacterium bovis BCG (intralesional live BCG) for the treatment of metastatic melanoma resulted in regression of directly injected, and occasionally of distal lesions. However, intralesional-BCG is less effective in p ...

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

Mauro Delorenzi, Alexis Rapin, Dominique Velin, Esther Bovay, François Renevey

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 ...

Tumor-associated factors are enriched in lymphatic exudate compared to plasma in metastatic melanoma patients

Melody Swartz, Davide Demurtas, Lambert Charles François Potin, Patricia Corthésy Henrioud, Léa Maillat, Romain Hamelin, Natacha Anne-Sophie Bordry, Maria Anna Sofia Broggi, Alexandre Harari

Liquid biopsies allow monitoring of cancer progression and detection of relapse, but reliable biomarkers in melanoma are lacking. Because secreted factors preferentially drain to lymphatic vessels before dilution in the blood, we hypothesized that lymph sh ...

Amphiphilic nanoparticle delivery enhances the anticancer efficacy of a TLR7 ligand via local immune activation

Francesco Stellacci, Marie Mueller, Ye Yang, Ahmet Bekdemir

Although immunotherapy shows great promise for the long-term control of cancer, many tumors still fail to respond to treatment. To improve the outcome, the delivery of immunostimulants to the lymph nodes draining the tumor, where the antitumor immune respo ...

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 ...

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

Melody Swartz, Olivier Michielin, Natacha Anne-Sophie Bordry, Manuel Andreas Fankhauser, Esther Danenberg, Maria Anna Sofia Broggi, 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) ...

Development of a nano-adjuvant cancer vaccine and its evaluation for melanoma in combination with radiotherapy

Sylvie Hauert

Cancer is the second leading cause of death in the world and melanoma is the deadliest type of skin cancer. Although surgery, radiotherapy and chemotherapy are still standard treatments, the discovery of the role played by the immune system in cancer has a ...

New roles of the lymphatic endothelium in modulating adaptive immunity: implications for immune tolerance and cancer immunotherapy

Lambert Charles François Potin

Lymphatic vessels have traditionally been considered as passive conduits for interstitial fluid drainage and for immune cell trafficking to lymph nodes. In the last two decades, many studies have challenged this classical dogma: lymphatic endothelial cells ...

Multiple roles of lymphatic vessels in peripheral lymph node development

Esther Bovay, Ann-Helen Willrodt, Borja Prat Luri

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 ...

Improving Efficacy and Safety of Agonistic Anti-CD40 Antibody Through Extracellular Matrix Affinity

Jeffrey Alan Hubbell, Melody Swartz, Lambert Charles François Potin, Martina Damo, Jun Ishihara, Kazuto Fukunaga

CD40 is an immune costimulatory receptor expressed by antigen-presenting cells. Agonistic anti-CD40 antibodies have demonstrated considerable antitumor effects yet can also elicit serious treatment-related adverse events, such as liver toxicity, including ...

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

Melody Swartz, Witold Waldemar Kilarski, Esra Güç, Marco Pisano, 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, Praneeth Karempudi

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 ...
