Immunological effects of CD19.CAR-T cell therapy in systemic sclerosis: an extended case study.

Objective: The high potential of CD19.CAR-T cells to treat autoimmune diseases such as Systemic Sclerosis (SSc) supposedly relies on the disappearance of autoantibodies. Here we investigated effects of CAR-T cells on the innate immune system which is an important contributor to pathology in SSc.

Investigation of Muscarinic Acetylcholine Receptor M Activation in Atomistic Detail: A Chemist's Viewpoint.

We analyzed the precise ligand:receptor interactions required for activation of the muscarinic acetylcholine receptor M, a prototypical G protein-coupled receptor and potential diabetes target. Starting from literature-known compounds and docking solutions, ligands were tailored for the modulation of this receptor's activation. Several aspects of the structure-activity relationship of agonists were investigated in atomistic detail, in order to delineate how the receptor can be activated via the orthosteric site.

ASH living guidelines on use of anticoagulation for thromboprophylaxis in patients with COVID-19: executive summary.

COVID-19-related critical and acute illness are associated with an increased risk of venous thromboembolism (VTE). These evidence-based recommendations of the American Society of Hematology (ASH) are intended to support patients, clinicians, and other healthcare professionals in decisions about the use of anticoagulation for thromboprophylaxis in patients with COVID-19-related critical illness, acute illness, and those being discharged from the hospital, who do not have suspected or confirmed VTE. ASH formed a multidisciplinary panel, including three patient representatives, and applied a conflicts of interest management policy to minimize potential bias.

Depth-resolved characterization of Meissner screening breakdown in surface treated niobium.

We report direct measurements of the magnetic field screening at the limits of the Meissner phase for two superconducting niobium (Nb) samples. The samples are processed with two different surface treatments that have been developed for superconducting radio-frequency (SRF) cavity applications-a "baseline" treatment and an oxygen-doping ("O-doping") treatment. The measurements show: (1) that the screening length is significantly longer in the "O-doping" sample compared to the "baseline" sample; (2) that the screening length near the limits of the Meissner phase increases with applied field; (3) the evolution of the screening profile as the material transitions from the Meissner phase to the mixed phase; and (4) a demonstration of the absence of any screening profile for the highest applied field, indicative of the full flux entering the sample.

Fcγ-receptor-IIIA bioactivity of circulating and synovial immune complexes in rheumatoid arthritis.

Objective: Previous technical limitations prevented the proof of Fcγ-receptor (FcγR)-activation by soluble immune complexes (sICs) in patients. FcγRIIIa (CD16) is a risk factor in rheumatoid arthritis (RA). We aimed at determining the presence of CD16-activating sICs in RA and control diseases.
