Rare predicted loss-of-function variants of type I IFN immunity genes are associated with life-threatening COVID-19

Jacques Fellay, Yu Zhang, Peng Zhang, Qian Zhang

BackgroundWe previously reported that impaired type I IFN activity, due to inborn errors of TLR3- and TLR7-dependent type I interferon (IFN) immunity or to autoantibodies against type I IFN, account for 15-20% of cases of life-threatening COVID-19 in unvac ...

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 ...

Inborn errors of type I IFN immunity in patients with life-threatening COVID-19

Jacques Fellay, Rui Yang, Jie Chen, Yu Zhang, Xavier Duval, Peng Zhang, Qian Zhang, Zhiyong Liu, Juan Li

Clinical outcome upon infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ranges from silent infection to lethal coronavirus disease 2019 (COVID-19). We have found an enrichment in rare variants predicted to be loss-of-function (LOF ...

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 ...

Amphiphilic nanoparticle delivery enhances the anticancer efficacy of a TLR7 ligand via local immune activation

Francesco Stellacci, Ye Yang, Ahmet Bekdemir, Marie Mueller

Although immunotherapy shows great promise for the long-term control of cancer, many tumors still fail to respond to treatment. To improve the outcome, the delivery of immunostimulants to the lymph nodes draining the tumor, where the antitumor immune respo ...

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

Xavier Fredy René Quaglia-Thermes, Giacomo Olimpio Diaceri, Jeffrey Alan Hubbell, Melody Swartz, 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 ...

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 ...

Dose-dependent effects of morphine on lipopolysaccharide (LPS)-induced inflammation, and involvement of multixenobiotic resistance (MXR) transporters in LPS efflux in teleost fish

Kristin Schirmer

Opioid drugs, such as morphine (MO), detected in aquatic environments worldwide, may harm fish due to their semi-persistence and ability to potently interact with molecular targets conserved across vertebrates. Here, we established a waterborne bacterial l ...

The In-Vivo Use of Superparamagnetic Iron Oxide Nanoparticles to Detect Inflammation Elicits a Cytokine Response but Does Not Aggravate Experimental Arthritis

Heinrich Hofmann, Lionel André Maurizi

Background Superparamagnetic Iron Oxide Nanoparticles (SPION) are used in diagnostic imaging of a variety of different diseases. For such in-vivo application, an additional coating with a polymer, for example polyvinyl alcohol (PVA), is needed to stabilize ...

PPAR beta/delta activation of CD300a controls intestinal immunity

Johan Auwerx

Macrophages are important for maintaining intestinal immune homeostasis. Here, we show that PPAR beta/delta (peroxisome proliferator-activated receptor beta/delta) directly regulates CD300a in macrophages that express the immunoreceptor tyrosine based-inhi ...
