Exploring the interplay of molecular pattern and valency for selective interactions at the bio-interface

Cell-cell communication is fundamental for immune balance. Multivalent interactions of surface receptors at immune interfaces drive specific communication, with stimulatory and inhibitory signals guiding the immune outcome. Notably, the valency, affinity, ...

The role of the Nimrod proteins in the Drosophila immune system

Bianca Marie Petrignani

The use of tractable model organisms such as Drosophila melanogaster and the powerful genetic tools they offer has contributed significantly to recent advances in comprehension of innate immunity, notably phagocytosis. To date, several phagocytic transmemb ...

Role of Nimrod receptors in the Drosophila melanogaster cellular immune response

Claudia Melcarne

The use of modern molecular biology tools and simple but powerful tractable model organisms such as Drosophila has contributed significantly to our recent advances in the innate immunity field, notably phagocytosis. Since 2001, many phagocytic transmembran ...

Two Nimrod receptors, NimC1 and Eater, synergistically contribute to bacterial phagocytosis in Drosophila melanogaster

Bruno Lemaitre, Jan Paul Dudzic, Elodie Julie Virginie Ramond, Andrew Jonathan Bretscher, Claudia Melcarne

Eater and NimC1 are transmembrane receptors of the Drosophila Nimrod family, specifically expressed in haemocytes, the insect blood cells. Previous ex vivo and in vivoRNAi studies have pointed to their role in the phagocytosis of bacteria. Here, we have cr ...

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 ...

Nucleic acids presenting polymer nanomaterials as vaccine adjuvants

Maartje Martina Cornelia Bastings, Kaltrina Paloja, Alice Comberlato

Most vaccines developed today include only the antigens that best stimulate the immune system rather than the entire virus or microbe, which makes vaccine production and use safer and easier, though they lack potency to induce acceptable immunity and long- ...

Precision targeting of tumor macrophages with a CD206 binding peptide

Michele De Palma, Mario Leonardo Squadrito

Tumor-associated macrophages (TAMs) expressing the multi-ligand endocytic receptor mannose receptor (CD206/MRC1) contribute to tumor immunosuppression, angiogenesis, metastasis, and relapse. Here, we describe a peptide that selectively targets MRC1-express ...

PGRP-SD, an Extracellular Pattern-Recognition Receptor, Enhances Peptidoglycan-Mediated Activation of the Drosophila Imd Pathway

Bruno Lemaitre, Igor Iatsenko

Activation of the innate immune response in Metazoans is initiated through the recognition of microbes by host pattern-recognition receptors. In Drosophila, diaminopimelic acid ( DAP)-containing peptidoglycan from Gram-negative bacteria is detected by the ...

Bioengineering approaches in immunotherapy : from basic to translational applications

Martina Damo

Vaccination has been regarded to as the most attractive immunotherapy for cancer because of its ability to instruct immune cells to recognize and kill tumor cells. Exosomes are one of the most recent discoveries translated from basic biology into experimen ...

Genetic, molecular and physiological basis of variation in Drosophila gut immunocompetence

Bruno Lemaitre, Bart Deplancke, Andreas Massouras, Dani Osman, Maroun Bou Sleiman

Gut immunocompetence involves immune, stress and regenerative processes. To investigate the determinants underlying inter-individual variation in gut immunocompetence, we perform enteric infection of 140 Drosophila lines with the entomopathogenic bacterium ...

Arranged Sevenfold: Structural Insights into the C-Terminal Oligomerization Domain of Human C4b-Binding Protein

Matteo Dal Peraro, Matteo Thomas Degiacomi

The complement system as a major part of innate immunity is the first line of defense against invading microorganisms. Orchestrated by more than 60 proteins, its major task is to discriminate between host cells and pathogens and to initiate immune response ...

MiR-511-3p Modulates Genetic Programs of Tumor-Associated Macrophages

Mario Leonardo Squadrito, Ferdinando Pucci

Expression of the mannose receptor (MRC1/CD206) identifies macrophage subtypes, such as alternatively activated macrophages (AAMs) and M2-polarized tumor-associated macrophages (TAMs), which are endowed with tissue-remodeling, proangiogenic, and protumoral ...

Dendritic cell activation and T cell priming with adjuvant- and antigen-loaded oxidation-sensitive polymersomes

Jeffrey Alan Hubbell, Melody Swartz, Armando Stano

While current subunit vaccines successfully induce humoral immune responses, a need exists for vaccine strategies to elicit strong cell-mediated immunity to address diseases such as cancer and chronic viral infection. Polymersomes are stable vesicles compo ...

Angiopoietin-2 regulates gene expression in TIE2-expressing monocytes and augments their inherent proangiogenic functions

Michele De Palma

TIE2-expressing monocytes/macrophages (TEM) are a highly proangiogenic subset of myeloid cells in tumors. Here, we show that circulating human TEMs are already preprogrammed in the circulation to be more angiogenic and express higher levels of such proangi ...
