The inhibition of antithrombin by peptidylarginine deiminase 4 may contribute to pathogenesis of rheumatoid arthritis [PDF]

Rheumatology, 2005
The gene for peptidylarginine deiminase 4 (PADI4) has been found to be closely associated with rheumatoid arthritis (RA). Peptidylarginine deiminase (PADI) catalyses the post-translational modification of peptidylarginine to citrulline, a reaction known as citrullination. PADI extracted from rabbit muscle has been reported to citrullinate antithrombin,

Neutrophil‐based immunotherapy: A metabolic lens on mechanisms and therapeutic implications

Clinical and Translational Medicine, Volume 16, Issue 8, August 2026.
TAN metabolic reprogramming critically contributes to tumour immune evasion. A 4‑Tier TAN‑MetaC classification framework is proposed, along with an overview of translational opportunities and bottlenecks for TAN metabolism‑targeted immunotherapies. Abstract Background Tumor‐associated neutrophils (TANs) serve as pivotal immune modulators in the tumor ...

The role of peptidylarginine deiminase 4 in ovarian cancer cell tumorigenesis and invasion

Tumor Biology, 2015
Peptidylarginine deiminase 4 (PADI4) is an enzyme that converts both histone arginine and mono-methyl arginine residues to citrulline, and it has been detected in various subtypes of ovarian cancer. However, the mechanism of action of PADI4 in ovarian carcinogenesis remains unknown.

Neutrophil extracellular trap regulators in sickle cell disease: Modulation of gene expression of PADI4, neutrophil elastase, and myeloperoxidase during vaso‐occlusive crisis

Research and Practice in Thrombosis and Haemostasis, 2021
Background Recent evidence suggests that generation of neutrophil extracellular traps (NETosis), one of the components of immunothrombosis, is associated with the pathogenesis of both venous thromboembolism and sickle cell disease (SCD).

Neutrophil extracellular traps induced by activated platelets as a cause of neutrophil–platelet aggregation in β‐thalassaemia/haemoglobin E patients

British Journal of Haematology, Volume 209, Issue 2, Page 703-717, August 2026.
Abnormal neutrophils and platelets in splenectomised β‐thalassaemia/haemoglobin E (HbE) disease contribute to neutrophil–platelet aggregation, leading to a high risk of thrombus formation. Activated platelets induce neutrophils to generate neutrophil extracellular trap (NETs) via the P‐selectin–P‐selectin glycoprotein ligand‐1 (PSGL1) pathway, which ...

Structural basis for histone N-terminal recognition by human peptidylarginine deiminase 4 [PDF]

Proceedings of the National Academy of Sciences, 2006
Histone arginine methylation is a posttranslational modification linked to the regulation of gene transcription. Unlike other posttranslational modifications, methylation has generally been regarded as stable, and enzymes that demethylate histone arginine residues have not been identified.

Unveiling Gut Homeostasis Disruption in Sepsis: Towards an Integrated Mechanistic and Translational Roadmap

Cell Proliferation, Volume 59, Issue 8, August 2026.
Elucidating the contribution of gut‐organ axes will provide new insights for developing combined therapeutic strategies against sepsis‐associated multiple organ dysfunction. ABSTRACT Sepsis, a life‐threatening clinical syndrome precipitated by a maladaptive host response to infection, is associated with substantial morbidity and high mortality rates ...

Beyond Sequence: Posttranslational Remodeling of Antigens in Autoimmunity

Immunological Reviews, Volume 341, Issue 1, August 2026.
ABSTRACT Autoimmune responses are often attributed to failed tolerance to self‐proteins, yet protein expression alone cannot explain why certain antigens dominate disease, why autoreactivity emerges under stress, or why specific HLA alleles shape risk.

Myelin localization of peptidylarginine deiminases 2 and 4: comparison of PAD2 and PAD4 activities [PDF]

Laboratory Investigation, 2008
An understanding of the structure and composition of the myelin sheath is essential to understand the pathogenesis of demyelinating diseases such as multiple sclerosis (MS). The presence of citrulline in myelin proteins in particular myelin basic protein (MBP) causes an important change in myelin structure, which destabilizes myelin.
