IL-4R alpha-Expressing B Cells Are Required for CXCL13 Production by Fibroblastic Reticular Cells

Nicola Harris, Lalit Kumar Dubey

Adaptive type 2 immune responses against the intestinal helminth Heligmosomoides polygyrus (Hp) require the interaction of follicle-associated CXCR5(+) dendritic cells with naive T cells in the draining mesenteric lymph nodes (mLNs). However, the source of ...

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) ...

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 ...

Advancing immunotherapy for HPV-related cancers: Improving therapeutic vaccination approaches and understanding the immunosuppressive role of myeloid cells

Gabriele Galliverti

Human Papilloma Viruses (HPVs) are the most common sexually transmitted agents worldwide, and chronic infection with oncogenic HPVs can lead to the development of lesions in the cervix, the vulva, and the head and neck region. In some patients, these lesio ...

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 ...

Perivascular macrophages in health and disease

Michele De Palma

Macrophages are a heterogeneous group of cells that are capable of carrying out distinct functions in different tissues, as well as in different locations within a given tissue. Some of these tissue macrophages lie on, or close to, the outer (abluminal) su ...

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 ...

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

Melody Swartz, Marco Pisano, Witold Waldemar Kilarski, 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, 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 ...
