Regulatory T cells engineered with TCR signaling-responsive IL-2 nanogels suppress alloimmunity in sites of antigen encounter

Adoptive cell transfer of ex vivo expanded regulatory T cells (T-r(egs)) has shown immense potential in animal models of auto- and alloimmunity. However, the effective translation of such T-reg therapies to the clinic has been slow. Because T-reg homeostas ...

Clinical relevance of low-densityPlasmodium falciparumparasitemia in untreated febrile children: A cohort study

Mary-Anne Hartley

Background Low-density (LD)Plasmodiuminfections are missed by standard malaria rapid diagnostic tests (standard mRDT) when the blood antigen concentration is below the detection threshold. The clinical impact of these LD infections is unknown. This study i ...

Evaluation of Auramine O staining and conventional PCR for leprosy diagnosis: A comparative cross-sectional study from Ethiopia

Stewart Cole, Charlotte Avanzi, Philippe Busso

Background Diagnosis of leprosy mainly relies on clinical examination due to the inconsistent sensitivity and poor reproducibility of the current laboratory tests. Utilisation of alternative methods to the standard Ziehl Neelsen (ZN), Fite-Faraco (FF) and ...

Clocks do not tick in unison: isolation of Clock and vrille shed new light on the clockwork model of the sand fly Lutzomyia longipalpis

Antonio Carlos Alves Meireles Filho

Background: Behavior rhythms of insect vectors directly interfere with the dynamics of pathogen transmission to humans. The sand fly Lutzomyia longipalpis is the main vector of visceral leishmaniasis in America and concentrates its activity around dusk. De ...

The C-type Lectin Receptors Dectin-1, MR, and SIGNR3 Contribute Both Positively and Negatively to the Macrophage Response to Leishmania infantum

Johan Auwerx

Macrophages act as the primary effector cells during Leishmania infection through production of reactive oxygen species (ROS) and interleukin-1 beta (IL-1 beta). However, how macrophage-killing mechanisms are activated during Leishmania-macrophage interact ...

Differential peptide binding to CD40 evokes counteractive responses

Giovanni Dietler, Sandor Kasas, Charles Roduit, Livan Bladimir Alonso Sarduy, Bhaskar Saha

The antigen-presenting cell-expressed CD40 is implied in the regulation of counteractive immune responses such as induction of pro-inflammatory and anti-inflammatory cytokines interleukin (IL)-12 and IL-10, respectively. The mechanism of this duality in CD ...

Antigen delivery to dendritic cells by poly(propylene sulfide) nanoparticles with disulfide conjugated peptides: Cross-presentation and T cell activation

Jeffrey Alan Hubbell, Melody Swartz, Sachiko Hirosue, Iraklis Kourtis

Vaccines aiming to activate cytotoxic T cells require cross-presentation of exogenous antigen by antigen-presenting cells (APCs). We recently developed a synthetic nanoparticle vaccine platform that targets lymph node-resident dendritic cells (DCs), capabl ...

IL28B genotype is associated with differential expression of intrahepatic interferon-stimulated genes in patients with chronic hepatitis C

Jacques Fellay

Genetic variation in the IL28B (interleukin 28B; interferon lambda 3) region has been associated with sustained virological response (SVR) rates in patients with chronic hepatitis C (CHC) who were treated with peginterferon-α and ribavirin. We hypothesized ...

Potent and Selective Antiplasmodial Activity of the Cyanobacterial Alkaloid Nostocarboline and its Dimers

Karl Gademann

The quaternary β-carbolinium alkaloid nostocarboline from the cyanobacterium Nostoc 78-12A and ten bis-cationic dimeric derivatives were evaluated against four protozoan parasites and low micromolar values against Trypanosoma brucei, submicromolar values a ...

Tumor-targeted interferon-alpha delivery by Tie2-expressing monocytes inhibits tumor growth and metastasis

Michele De Palma, Ferdinando Pucci

The use of type I interferons (IFNs) in cancer therapy has been limited by ineffective dosing and significant toxicity. Here, we exploited the tumor-homing ability of proangiogenic Tie2-expressing monocytes (TEMs) to deliver IFN-alpha to tumors. By transpl ...
