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 ...

Integration of hybrid material systems in conformable neural interfaces

Florian Dylan Fallegger

Neural interfaces are devices that are implanted into the body and interface electrically with the central (CNS) or peripheral nervous system. They are inserted surgically for short periods of time or chronically to diagnose or treat several neural disease ...

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

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

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 ...

An Overview of Serum Albumin Interactions with Biomedical Alloys

Stefano Mischler, Anna Neus Igual Muñoz, Oksana Klok

Understanding the interactions between biomedical alloys and body fluids is of importance for the successful and safe performance of implanted devices. Albumin, as the first protein that comes in contact with an implant surface, can determine the biocompat ...

Experimental Drainage Device to Reduce Lymphoedema in a Rat Model

Nikolaos Stergiopoulos, Marco Pisano, Melody Swartz, 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, Witold Waldemar Kilarski

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 ...

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

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

Rapid evaluation of bioactive Ti-based surfaces using an in vitro titration method

Paul Bowen, Jacques Lemaître, Weitian Zhao

The prediction of implant behavior in vivo by the use of easy-to-perform in vitro methods is of great interest in biomaterials research. Simulated body fluids (SBFs) have been proposed and widely used to evaluate the bone-bonding ability of implant materia ...

Spatiotemporal stimulation strategies in neuroprostheses to improve locomotion after spinal cord injury

Jérôme Gandar

Spinal cord injury (SCI) disrupts communication within central nervous system and lead to range of neurological disorders including paralysis. Current rehabilitation strategies to restore locomotion are poorly effective in people with severe SCI. Epidural ...

Multiple roles of lymphatic vessels in peripheral lymph node development

Borja Prat Luri, Esther Bovay, Ann-Helen Willrodt

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 ...

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

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

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) ...

Knee Implant Loosening Detection: A Vibration Analysis Investigation

Kamiar Aminian, Arash Arami, Hossein Rouhani

Knee implant loosening is mainly caused by the weakness of the prosthesis-bone interface and is the main reason for surgical revisions. However, pre-operative diagnosis is difficult due to lack of accurate tests. In this study, we developed a vibration-bas ...
