Adult Drosophila Lack Hematopoiesis but Rely on a Blood Cell Reservoir at the Respiratory Epithelia to Relay Infection Signals to Surrounding Tissues

Bruno Lemaitre, Elodie Julie Virginie Ramond

The use of adult Drosophila melanogaster as a model for hematopoiesis or organismal immunity has been debated. Addressing this question, we identify an extensive reservoir of blood cells (hemocytes) at the respiratory epithelia (tracheal air sacs) of the t ...

Podosomes, But not the Maturation status, Determine the Protease-Dependent 3D Migration in human Dendritic cells

Romain Guiet

Dendritic cells (DC) are professional Antigen-Presenting Cells scattered throughout antigen-exposed tissues and draining lymph nodes, and survey the body for pathogens. Their ability to migrate through tissues, a 3D environment, is essential for an effecti ...

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

Jeffrey Alan Hubbell, Melody Swartz, Martina Damo, Lambert Charles François Potin

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 ...

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 ...

High-throughput quantitation of inorganic nanoparticle biodistribution at the single-cell level using mass cytometry

Francesco Stellacci, Li Tang, Ahmet Bekdemir

Inorganic nanoparticles (NPs) are studied as drug carriers, radiosensitizers and imaging agents, and characterizing nanoparticle biodistribution is essential for evaluating their efficacy and safety. Tracking NPs at the single-cell level with current techn ...

Primary human and rat beta cells release the intracellular autoantigens GAD65, IA-2 and proinsulin in exosomes together with cytokine-induced enhancers of immunity

Jeffrey Alan Hubbell, Melody Swartz, Michele De Palma, Davide Demurtas, Romain Hamelin, Sachiko Hirosue, Chiara Cianciaruso, Edward Allen Phelps, Steinunn Baekkeskov Hanahan

The target autoantigens in several organ-specific autoimmune diseases, including type 1 diabetes (T1D), are intracellular membrane proteins, whose initial encounter with the immune system is poorly understood. Here we propose a new model for how these prot ...

T-cell surface modification with synthetic nanomaterials for cell-mediated delivery to the central nervous system

Maxime Ayer

The future of medicine lies in therapeutic approaches that can specifically target sites of disease and induce a localized and effective therapeutic effect. Cell-mediated delivery, especially using cells of the circulatory repertoire such as T lymphocytes, ...

Perivascular Macrophages Limit Permeability

Melody Swartz, Michele De Palma, Mario Leonardo Squadrito, Esra Güç

Objective-Perivascular cells, including pericytes, macrophages, smooth muscle cells, and other specialized cell types, like podocytes, participate in various aspects of vascular function. However, aside from the well-established roles of smooth muscle cell ...

Minimal model for spontaneous cell polarization and edge activity in oscillating, rotating and migrating cells

Jean-Jacques Meister, Alexander Verkhovskiy, Chiara Gabella, Franck Claude Raynaud, Alicia Carine Bornert, Mark Etienne Ambühl

How cells break symmetry and organize activity at their edges to move directionally is a fundamental question in cell biology. Physical models of cell motility commonly incorporate gradients of regulatory proteins and/or feedback from the motion itself to ...
