Arthritis &Rheumatology, Accepted Article.Introduction Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Microbiology, 1981 Cyclic AMP phosphodiesterase in Klebsiella aerogenes is a soluble cytoplasmic enzyme with an apparent Km of 0.9 mM and a pH optimum of 7.0. It was inhibited by EDTA, Mg2+ and other metal ions. The enzyme activity was inhibited or activated by some nucleotides but not by any metabolite except pyruvate.

Allergy, EarlyView.ABSTRACT In the last decades, critical advancements in research technology and knowledge on disease mechanisms steered therapeutic approaches for chronic inflammatory diseases towards unprecedented target specificity. For allergic and chronic lung diseases, biologic drugs pioneered this goal, acquiring on the way—through the clinical use of monoclonal ...

Non‐canonical PKG1 regulation in cardiovascular health and disease
British Journal of Pharmacology, EarlyView.It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.
