Antibodies expand the scope of angiotensin receptor pharmacology

G-protein-coupled receptors (GPCRs) are key regulators of human physiology and are the targets of many small-molecule research compounds and therapeutic drugs. While most of these ligands bind to their target GPCR with high affinity, selectivity is often l ...

A PD-L1/EGFR bispecific antibody combines immune checkpoint blockade and direct anti-cancer action for an enhanced anti-tumor response

Jaume Bonet Martinez

Immune checkpoint blockade (ICB) with antibodies has shown durable clinical responses in a wide range of cancer types, but the overall response rate is still limited. Other effective therapeutic modalities to increase the ICB response rates are urgently ne ...

Site-selective template-directed synthesis of antibody Fc conjugates with concomitant ligand release

Natalia Gasilova, Jean-Manuel Segura, David Viertl

Template-directed methods are emerging as some of the most effective means to conjugate payloads at selective sites of monoclonal antibodies (mAbs). We have previously reported a method based on an engineered Fc-III reactive peptide to conjugate a radionuc ...

Structural basis of drug recognition by the multidrug transporter ABCG2

Henning Paul-Julius Stahlberg, Dongchun Ni

ABCG2 is an ATP-binding cassette (ABC) transporter whose function affects the pharmacokinetics of drugs and contributes to multidrug resistance of cancer cells. While its interaction with the endogenous substrate estrone-3-sulfate (E1S) has been elucidated ...

Protease-activation using anti-idiotypic masks enables tumor specificity of a folate receptor 1-T cell bispecific antibody

Henning Paul-Julius Stahlberg

T-cell bispecific antibodies (TCBs) crosslink tumor and T-cells to induce tumor cell killing. While TCBs are very potent, on-target off-tumor toxicity remains a challenge when selecting targets. Here, we describe a protease-activated anti-folate receptor 1 ...

Redox Properties of Native and Damaged DNA from Mixed Quantum Mechanical/Molecular Mechanics Molecular Dynamics Simulations

Ursula Röthlisberger, Ivano Tavernelli, Polydefkis Diamantis

The redox properties of two large DNA fragments composed of 39 base pairs, differing only by an 8-oxoguanine (8oxoG) defect replacing a guanine (G), were investigated in physiological conditions using mixed quantum mechanical/molecular mechanical (QM/MM) m ...

Allosteric Protein Switches based on Antibody Mimetics

Helen Rebecca Ostlund Farrants

Synthetic protein switches are proteins that can be controlled by an external input, and are useful tools to probe protein function. Antibody fragments and antibody mimetics can be selected to bind, activate, or inhibit several diverse protein targets. Nev ...

Effect of Fc Receptor Genetic Diversity on HIV-1 Disease Pathogenesis

Jacques Fellay, Christian Axel Wandall Thorball

Fc receptor (FcR) genes collectively have copy number and allelic polymorphisms that have been implicated in multiple inflammatory and autoimmune diseases. This variation might also be involved in etiology of infectious diseases. The protective role of Fc- ...

Memristive Biosensors based on Full-size Antibodies and Antibody Fragments

Giovanni De Micheli, Ioulia Tzouvadaki, Sandro Carrara, Sébastien Naus

For the first time memristive biosensors developed by the incorporation of scAbs (single-chain antibody fragments) enabling label-free detection of free Prostate Specific Antigen (fPSA) for early-stage detection of prostate cancer (PC) are reported. In add ...

Bioluminescent Antibodies for Point-of-Care Diagnostics

Kai Johnsson, Rudolf Griss, Alberto Schena, Qiuliyang Yu, Lin Xue

We introduce a general method to transform antibodies into ratiometric, bioluminescent sensor proteins for the no-wash quantification of analytes. Our approach is based on the genetic fusion of antibody fragments to NanoLuc luciferase and SNAP-tag, the lat ...

Structural Features of the Box C/D snoRNP Pre-assembly Process Are Conserved through Species

Benjamin Marcel Daniel Rothé

Box C/D small nucleolar ribonucleoparticles (snoRNPs) support 2'-O-methylation of several target RNAs. They share a common set of four core proteins (SNU13, NOP58, NOP56, and FBL) that are assembled on different guide small nucleolar RNAs. Assembly of thes ...

TRIM33 switches off Ifnb1 gene transcription during the late phase of macrophage activation

Michele De Palma, Mario Leonardo Squadrito

Despite its importance during viral or bacterial infections, transcriptional regulation of the interferon-beta gene (Ifnb1) in activated macrophages is only partially understood. Here we report that TRIM33 deficiency results in high, sustained expression o ...

Immune Antibodies and Helminth Products Drive CXCR2-Dependent Macrophage-Myofibroblast Crosstalk to Promote Intestinal Repair

Duncan-Bruce Sutherland, Nicola Harris, Benjamin John Marsland, Beatrice Volpe, Julia Esser-von Bieren, Jérôme Bürgi

Helminth parasites can cause considerable damage when migrating through host tissues, thus making rapid tissue repair imperative to prevent bleeding and bacterial dissemination particularly during enteric infection. However, how protective type 2 responses ...
