Testing for the lupus anticoagulant: the good, the bad, and the ugly
Res Pract Thromb Haemost. 2024 Mar 18;8(3):102385. doi: 10.1016/j.rpth.2024.102385. eCollection 2024 Mar.ABSTRACTLupus anticoagulant (LA) represents 1 of the laboratory criteria for classification of patients as having definite antiphospholipid syndrome (APS). The other 2 laboratory criteria are anticardiolipin antibodies and anti-beta2-glycoprotein I antibodies. At least 1 of these antiphospholipid antibody (aPL) tests need to be positive, with evidence of persistence, together with evidence of at least 1 clinical criterion for APS, before a patient can be classified as having definite APS. LA and other aPL assays are als...

Upregulation of PD-1 and its ligands and expansion of T peripheral helper cells in the nephritic kidneys of lupus-prone BXSB- < em > Yaa < /em > mice
CONCLUSION: The results of this study suggest that kidney-infiltrating PD-1+ Tph cells expanded concomitantly with the upregulation of PD-L1 and PD-L2 in the kidneys and the progression of lupus nephritis.PMID:38622764 | DOI:10.1177/09612033241247908 (Source: Lupus)

The Oral-Lung Microbiome Axis in Connective Tissue Disease-Related Interstitial Lung Disease
Semin Respir Crit Care Med. 2024 Apr 16. doi: 10.1055/s-0044-1785673. Online ahead of print.ABSTRACTConnective tissue disease-related interstitial lung disease (CTD-ILD) is a frequent and serious complication of CTD, leading to high morbidity and mortality. Unfortunately, its pathogenesis remains poorly understood; however, one intriguing contributing factor may be the microbiome of the mouth and lungs. The oral microbiome, which is a major source of the lung microbiome through recurrent microaspiration, is altered in ILD patients. Moreover, in recent years, several lines of evidence suggest that changes in the oral and lu...

Phosphatidic Acid Promoting the Generation of Interleukin ‐17A Producing Double‐Negative T Cells by Enhancing mTORC1 Signaling in Lupus
ConclusionThe accumulation of PA in T cells could activate the mTORC1 pathway, promoting DNT cell expansion and IL-17A secretion, resulting in GCB cell abnormalities in lupus. (Source: Arthritis and Rheumatology)

The unique interplay between antinuclear antibodies and nuclear molecules in the pathogenesis of SLE
Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease that primarily affects young women and causes a wide range of inflammatory manifestations. The hallmark of SLE is the production of antibodies to components of the cell nucleus (antinuclear antibodies or ANAs). These antibodies can bind to DNA, RNA and protein complexes with nucleic acids. Among ANAs, antibodies to DNA (anti-DNA) are markers for classification and disease activity, waxing and waning in many patients. In the blood, anti-DNA antibodies can bind DNA to form immune complexes with two distinct roles in pathogenesis: renal deposition to provok...

Reverse zoonotic transmission events of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been described since the start of the pandemic, and the World Organisation for Animal Health (WOAH) designated the detection of SARS-CoV-2 in animals a reportable disease. Eighteen domestic and zoo animals in Great Britain and Jersey were tested by APHA for SARS-CoV-2 during 2020&ndash;2023. One domestic cat (Felis catus), three domestic dogs (Canis lupus familiaris), and three Amur tigers (Panthera tigris altaica) from a zoo were confirmed positive d...

Identification of EPSTI1 as a new potential biomarker for SLE based on GEO database
ConclusionTogether,EPSTI1 was found to be a potential biomarker for SLE, closely related to T cell immune imbalance.Key Points• EPSTI1 expression was significantly increased in PBMCs of SLE patients.• EPSTI1 was positively correlated with disease activity and T cell activation- or differentiation-associated genes in SLE patients.• EPSTI1 might have a good diagnostic value for SLE.

A retrospective cohort study of Epstein-Barr virus infection status and systemic lupus erythematosus
ConclusionsPatients with SLE with lytic EBV infection have higher disease activity and take longer to achieve remission. Our study furthers our understanding of the relationship between SLE and EBV infection and may inform better treatment practices in the future. (Source: Clinical Rheumatology)

Isolation and Single-Cell Transcriptomic Analysis of Murine Regulatory B Cells
Methods Mol Biol. 2024;2782:159-166. doi: 10.1007/978-1-0716-3754-8_12.ABSTRACTRegulatory B (Breg) cells have been demonstrated to play an important role in the inhibition of a wide range of immunological responses, and they are absent or malfunction in autoimmune diseases like lupus. Breg cells can control immunological responses and keep the immune system in a balanced state by releasing immunosuppressive cytokines such as transforming growth factor-beta (TGF-β) and interleukin-10 (IL-10), which in turn promote regulatory T (Treg) cells and reduce effector T cell responses. Breg cells have also been linked to the modula...

Extracellular mitochondrial components as new biomarkers for lupus nephritis
This study has evaluated extracellular mitochondrial components, including cell-free mitochondria, and cell-free mitochondrial DNA as probable biomarkers of the degree of nephritis. Both showed a significant correlation with proteinuria and protein-creatinine ratio. Our study substantiates their usage as clinical biomarkers of nephritis upon their validation in a larger cohort of lupus nephritis patients and other forms of nephritis. Although the current data suggest using cell-free mitochondria as a biomarker of lupus nephritis is better than the cell-free mitochondrial DNA.PMID:38621786 | DOI:10.1177/09612033241247622 (Source: Lupus)
