Immunomodulatory Nanozymes as Programmable Redox–Immune Set‐Point Regulators

Small, EarlyView.
Conceptual phase space linking reactive oxygen species level/dynamics to immune state, with pathological set‐points for chronic inflammation, tumor escape, and degeneration contrasted against a central healthy redox–immune set‐point. Buffering and amplifying nanozymes are depicted as devices that dial redox tone up or down to steer diseased ...

DIAGNOSTIC VALUE OF ANTI-PEPTIDYLARGININE DEIMINASE TYPE 4 (PADI-4) AND ANTI- CITRULLINATED PEPTIDE ANTIBODIES (ACCP) IN IRAQI PATIENTS WITH RHEUMATOID ARTHRITIS [PDF]

Basrah Journal of Surgery, 2014
This study aimed to examine the value of anti peptidylarginine deiminase (anti-PADI-4) antibody and anti-cyclic citrullinated peptide (anti-CCP) antibody among Iraqi patients with RA and to determine whether the activity and severity in RA patients are ...

Roles, detection, and visualization of neutrophil extracellular traps in acute pancreatitis

Frontiers in Immunology, 2022
Neutrophil extracellular traps (NETs) are produced in large quantities at the site of inflammation, and they locally capture and eliminate various pathogens.

Lactate‐Primed NETosis Modulates Hepatic Regeneration During Acute Liver Failure via the TLR9/KLF15/AJUBA Axis

Cell Proliferation, EarlyView.
This study elucidates a novel Kupffer cell‐neutrophil‐hepatocyte axis that drives metabolic‐immune crosstalk during acute liver failure. Specifically, lactate‐primed NETs release links metabolic reprogramming to NETosis‐induced regenerative failure in hepatocytes via the TLR9/KLF15/AJUBA axis.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Targeting peptidyl-arginine deiminase 4 suppresses SARS-CoV-2 replication and modulates the inflammatory response

iScience
Summary: SARS-CoV-2, the causative agent of COVID-19, remains a global concern due to gaps in understanding its pathogenesis. Peptidyl-arginine deiminases (PADs) are emerging as key regulators of viral replication and inflammation.

Autoimmunity and Periodontitis

Journal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Periodontitis and Rheumatoid Arthritis—Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
Periodontitis and rheumatoid arthritis are linked via the two‐hit model whereby early periodontal inflammation can lead to autoantibody production capable of interacting with inflamed synovial tissues. Subsequent systemic inflammation can exacerbate the periodontal inflammatory response and bacterial dysbiosis leading to further autoantibody production

NLRP3 Inflammasome Assembly in Neutrophils Is Supported by PAD4 and Promotes NETosis Under Sterile Conditions

Frontiers in Immunology, 2021
Neutrophil extracellular trap formation (NETosis) and the NLR family pyrin domain containing 3 (NLRP3) inflammasome assembly are associated with a similar spectrum of human disorders. While NETosis is known to be regulated by peptidylarginine deiminase 4

Periodontitis and rheumatoid arthritis—Global efforts to untangle two complex diseases

Periodontology 2000, EarlyView.
Abstract Understanding the impact of oral health on rheumatoid arthritis (RA) will inform how best to manage patients with both periodontitis and RA. This review seeks to provide an update on interventional and mechanistic investigations, including a brief summary of European Research programs investigating the link between periodontitis and RA.
