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 ...

Disturbed mitochondrial dynamics in CD8(+)TILs reinforce T cell exhaustion

Li Tang, Nicola Vannini, George Coukos, Marcela Rincón-Restrepo, Min Gao, Fabien Franco

Ho and colleagues report that mitochondrial dysfunction and impaired mitophagy triggered by the tumor microenvironment lead to subsequent epigenetic changes and cause permanent T cell exhaustion and dysfunction. The metabolic challenges present in tumors a ...

Tumor lymphangiogenesis promotes T cell infiltration and potentiates immunotherapy in melanoma

Melody Swartz, Douglas Hanahan, Olivier Michielin, Krisztian Homicsko, Marcela Rincón-Restrepo, Christopher Claude Giuseppe Tremblay, Amanda Waite Lund, Laura Jeanbart, Lambert Charles François Potin, Manuel Andreas Fankhauser

In melanoma, vascular endothelial growth factor-C (VEGF-C) expression and consequent lymphangiogenesis correlate with metastasis and poor prognosis. VEGF-C also promotes tumor immunosuppression, suggesting that lymphangiogenesis inhibitors may be clinicall ...

Oxidation-sensitive polymersomes as vaccine nanocarriers enhance humoral responses against Lassa virus envelope glycoprotein

Jeffrey Alan Hubbell, Marcela Rincón-Restrepo, Melody Swartz, Sachiko Hirosue, Clara Galan Navarro, Stefan Kunz

Lassa virus (LASV) causes severe hemorrhagic fever with high mortality, yet no vaccine currently exists. Antibodies targeting viral attachment proteins are crucial for protection against many viral infections. However, the envelope glycoprotein (GP) 1 of L ...

Vaccine nanocarriers: Coupling intracellular pathways and cellular biodistribution to control CD4 vs CD8 T cell responses

Jeffrey Alan Hubbell, Marcela Rincón-Restrepo, Melody Swartz, Sachiko Hirosue, Edward Allen Phelps, Sylvie Hauert, Daniel Kenneth Bonner, Aaron Mayer

Nanoparticle delivery systems are known to enhance the immune response to soluble antigens (Ags) and are thus a promising tool for the development of new vaccines. Our laboratory has engineered two different nanoparticulate systems in which Ag is either en ...

Engineering nanoparticle-based vaccines: Implications for the quality of humoral and cellular immunity

Marcela Rincón-Restrepo

Vaccination is undoubtedly a major success in modern medicine. Yet, today there are pathogens for which no licensed or fully protective vaccines have been created. Development of vaccines based on subunit components has proven to be a safe and cost effecti ...

Steady-State Antigen Scavenging, Cross-Presentation, and CD8(+) T Cell Priming: A New Role for Lymphatic Endothelial Cells

Melody Swartz, Marcela Rincón-Restrepo, Efthymia Vokali, Sachiko Hirosue, Amanda Waite Lund, Patricia Corthésy Henrioud, Vidya Raghavan

Until recently, the known roles of lymphatic endothelial cells (LECs) in immune modulation were limited to directing immune cell trafficking and passively transporting peripheral Ags to lymph nodes. Recent studies demonstrated that LECs can directly suppre ...
