Antigens reversibly conjugated to a polymeric glyco-adjuvant induce protective humoral and cellular immunity

Jeffrey Alan Hubbell, Xavier Fredy René Quaglia-Thermes, Melody Swartz, Giacomo Olimpio Diaceri, Sachiko Hirosue, Laura Jeanbart, David Scott Wilson, Maria Anna Sofia Broggi, Michal Mateusz Raczy, Ruyi Wang

Fully effective vaccines for complex infections must elicit a diverse repertoire of antibodies (humoral immunity) and CD8+ T-cell responses (cellular immunity). Here, we present a synthetic glyco-adjuvant named p(Man-TLR7), which, when conjugated to antige ...

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 ...

Engineering opportunities in cancer immunotherapy

Melody Swartz, Laura Jeanbart

Immunotherapy has great potential to treat cancer and prevent future relapse by activating the immune system to recognize and kill cancer cells. A variety of strategies are continuing to evolve in the laboratory and in the clinic, including therapeutic non ...

6-Thioguanine-loaded polymeric micelles deplete myeloid-derived suppressor cells and enhance the efficacy of T cell immunotherapy in tumor-bearing mice

Jeffrey Alan Hubbell, Melody Swartz, Laura Jeanbart, Iraklis Kourtis

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immature myeloid cells that suppress effector T cell responses and can reduce the efficacy of cancer immunotherapies. We previously showed that ultra-small polymer nanoparticles eff ...

Nanoparticle conjugation enhances the immunomodulatory effects of intranasally delivered CpG in house dust mite-allergic mice

Jeffrey Alan Hubbell, Melody Swartz, Benjamin John Marsland, Alexandre de Titta, Marie Ballester, Laura Jeanbart

An emerging strategy in preventing and treating airway allergy consists of modulating the immune response induced against allergens in the lungs. CpG oligodeoxynucleotides have been investigated in airway allergy studies, but even if promising, efficacy re ...

The TLR4 Agonist Fibronectin Extra Domain A is Cryptic, Exposed by Elastase-2; use in a fibrin matrix cancer vaccine

Jeffrey Alan Hubbell, Mikaël Martino, Alexandre de Titta, Laura Jeanbart, Ziad Julier

Fibronectin (FN) is an extracellular matrix (ECM) protein including numerous fibronectin type III (FNIII) repeats with different functions. The alternatively spliced FN variant containing the extra domain A (FNIII EDA), located between FNIII 11 and FNIII 1 ...

Enhancing Efficacy of Anticancer Vaccines by Targeted Delivery to Tumor-Draining Lymph Nodes

Jeffrey Alan Hubbell, Melody Swartz, Alexandre de Titta, Pedro Romero, Marie Ballester, Laura Jeanbart, Patricia Corthésy Henrioud

The sentinel or tumor-draining lymph node (tdLN) serves as a metastatic niche for many solid tumors and is altered via tumor-derived factors that support tumor progression and metastasis. tdLNs are often removed surgically, and therapeutic vaccines against ...

Nanoparticle conjugation of CpG enhances adjuvancy for cellular immunity and memory recall at low dose

Jeffrey Alan Hubbell, Melody Swartz, Alexandre de Titta, Marie Ballester, Laura Jeanbart, Ziad Julier

In subunit vaccines, strong CD8(+) T-cell responses are desired, yet they are elusive at reasonable adjuvant doses. We show that targeting adjuvant to the lymph node (LN) via ultrasmall polymeric nanoparticles (NPs), which rapidly drain to the LN after int ...

Targeting and Modulating Tumor-Associated Sites with Novel Nanoparticle-Based Immunotherapies

Laura Jeanbart

Cancer is a global disease and a leading cause of death worldwide. While surgery, radiotherapy and chemotherapy comprise the classical tools to eradicate tumors, they do not cure cancer, cannot prevent metastases, lead to side effects, and most importantly ...
