T cell transgressions: tales of T cell form and function in diversedisease states.

Int Rev Immunol 2021 Jun 21:1-42. Epub 2021 Jun 21.

Department of Psychology and Neuroscience, Center for Neuroscience, University of Colorado, Boulder, Colorado, USA.

Insights into T cell form, function, and dysfunction are rapidly evolving. T cells have remarkably varied effector functions including protecting the host from infection, activating cells of the innate immune system, releasing cytokines and chemokines, and heavily contributing to immunological memory. Under healthy conditions, T cells orchestrate a finely tuned attack on invading pathogens while minimizing damage to the host. Read More

Using adalimumab serum concentration to choose a subsequent biological DMARD in rheumatoid arthritis patients failing adalimumab treatment (ADDORA-switch): study protocol for a fully blinded randomised superiority test-treatment trial.

Trials 2021 Jun 19;22(1):406. Epub 2021 Jun 19.

Department of Rheumatology, Sint Maartenskliniek, PO box 9011, 6500 GM, Nijmegen, the Netherlands.

Background: A substantial proportion of rheumatoid arthritis (RA) patients discontinues treatment with tumour necrosis factor inhibitors (TNFi) due to inefficacy or intolerance. After the failure of treatment with a TNFi, treatment can be switched to another TNFi or a bDMARD with a different mode of action (non-TNFi). Measurement of serum drug concentrations and/or anti-drug antibodies (therapeutic drug monitoring (TDM)) may help to inform the choice for the next step. Read More

Predictive analytics for step-up therapy: supervised or semi-supervised learning?

J Biomed Inform 2021 Jun 16:103842. Epub 2021 Jun 16.

Department of Biomedical Informatics, University of Utah, Salt Lake City, UT.

Background: Step-up therapy is a patient management approach that aims to balance the efficacy, costs and risks posed by different lines of medications. While the initiation of first line medications is a straightforward decision, stepping-up a patient to the next treatment line is often more challenging and difficult to predict. By identifying patients who are likely to move to the next line of therapy, prediction models could be used to help healthcare organizations with resource planning and chronic disease management.

Mechanistic insights into 5-lipoxygenase inhibition by pyocyanin: a molecular docking and molecular dynamics study.

J Biomol Struct Dyn 2021 Jun 18:1-9. Epub 2021 Jun 18.

Department of Biosciences, Sri Sathya Sai Institute of Higher Learning, Puttaparthi, Andhra Pradesh, India.

Pyocyanin, a redox-active phenazine pigment produced by , inhibits 5-lipoxygenase (5-LOX) activity. However, whether pyocyanin can directly block the enzymatic activity by binding at the active site still remains a question because of its ability to produce superoxide radicals and HO. With the objective of characterizing this mechanism, we carried out molecular docking and molecular dynamics simulations and performed Molecular Mechanics Poisson-Boltzmann surface area (MMPBSA) binding energy studies.

COVID-19 and RA share SPP1 myeloid pathway that drives PD-L1pos neutrophils and CD14pos monocytes.

JCI Insight 2021 Jun 18. Epub 2021 Jun 18.

Division of Rheumatology, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.

We explored the potential link between chronic inflammatory arthritis and COVID-19 pathogenic and resolving macrophage pathways and their role in COVID-19 pathogenesis. We found that BALF macrophage clusters FCN1pos and FCN1posSPP1pos predominant in severe COVID-19 were transcriptionally related to synovial tissue macrophage (STM) clusters CD48highS100A12pos and CD48posSPP1pos that drive Rheumatoid Arthritis (RA) synovitis. BALF macrophage cluster FABP4pos predominant in healthy lung was transcriptionally related to STM cluster TREM2pos that governs resolution of synovitis in RA remission. Read More
