The ornithine cycle in Neurospora and its genetic control [PDF]

open access: yes, 1944
It has been emphasized by Haldane (1) that for studies of intermediary metabolism "the new science of genetics furnishes a very powerful method." Such a method is founded upon the general premises that genes control many of the chemical reactions within ...

Conformational Plasticity of HLA-B27 Molecules Correlates Inversely With Efficiency of Negative T Cell Selection [PDF]

open access: yes, 2020
The development of autoimmune disorders is incompletely understood. Inefficient thymic T cell selection against self-peptides presented by major histocompatibility antigens (HLA in humans) may contribute to the emergence of auto-reactive effector cells ...

Tolerogenic citrullinated peptide for arthritis

open access: yesOncotarget, 2015
Disease-specific autoantibodies directed against post-translation citrullinated proteins/peptides (ACPAs) are specific serological markers for rheumatoid arthritis (RA) and have been accepted as one of the classification criteria for the disease. Beyond diagnosis these autoantibodies have also been shown also to predict disease severity.

Supplementary parenteral arginine corrects hypoargininaemia and rebalances plasma amino acid profiles in very preterm infants receiving parenteral nutrition: A prospective study

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Plasma amino acid (AA) profiles in parenteral nutrition (PN)–dependent very preterm infants (VPIs) consistently show overprovision of essential AA (EAA) and arginine deficiency. This may have implications for growth and immune/inflammatory responses.

Non‐canonical PKG1 regulation in cardiovascular health and disease

open access: yesBritish 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.

Citrullination – small change with a great consequence [PDF]

open access: yes, 2013
Citrullination is one of the possible post-translational modifications of proteins. It is based on a conversion of L-arginine residue (L-Arg) to L-citrulline residue (L-Cit). The reaction is catalyzed by peptidylarginine deiminases (PAD). The change of L-

Dysbiosis‐Mediated Inflammation: A Pathophysiological Link Between Rheumatoid Arthritis and Periodontitis

open access: yesJournal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To explore mechanistic links between rheumatoid arthritis (RA) and periodontitis (PD) through the lens of subgingival microbial dysbiosis–mediated inflammation. Methods Subgingival plaque from 100 volunteers with RA and PD (RAPD), 22 with RA (RAnoPD), 18 with PD (PDnoRA) and 19 healthy controls (noRAnoPD) was analysed using 16S‐amplicon ...

Inhibition of nitric oxide biosynthesis by anthocyanin fraction of blackberry extract. [PDF]

open access: yes, 2006
Anthocyanins are natural colorant belonging to the flavonoid family, widely distributed among flowers, fruits, and vegetables. Some flavonoids have been found to possess anticarcinogenic, cytotoxic, cytostatic, antioxidant, and anti-inflammatory ...

The dysregulation of innate immunity by Porphyromonas gingivalis in the etiology of Alzheimer's disease

open access: yesJournal of Internal Medicine, EarlyView.
Abstract The etiology of Alzheimer's disease (AD) remains under active debate. In this perspective, we explore the hypothesis that a primarily infection‐caused chronic dysregulation and weakening of human innate immunity via the underexpression, degradation, and inactivation of innate immune proteins necessary for direct antimicrobial effects and ...
