Kidney Disease in Lupus Patients Is Linked to Monocytes’ Aberrant Spliceosome and Altered Expression of IFN-Response Related Genes
Background/Purpose: The present study aimed at: 1- Identifying altered SLE monocytes transcriptomic signatures linked to the immune response and its association with clinical features. 2-…Abstract Number: 155 • 2020 Pediatric Rheumatology Symposium
Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) Is Characterized by a Novel Subset of Monocytes with Markers Associated with Crossing the Blood Brain Barrier (BBB)
Background/Purpose: Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) is characterized by abrupt onset of obsessive-compulsive disorder (OCD) and/or food restriction with other specified neuropsychiatric symptoms. 65% of…Abstract Number: 780 • 2019 ACR/ARP Annual Meeting
Changes in MiR-17-92 Cluster Expression Link Systemic Juvenile Idiopathic Arthritis, Monocyte-to-Macrophage Differentiation, and Interferon Regulation
Background/Purpose: MicroRNAs (miRNAs) are small noncoding RNAs which post-transcriptionally regulate gene expression. The miR-17-92 cluster is well characterized; its overexpression has been found to serve…Abstract Number: 1073 • 2019 ACR/ARP Annual Meeting
Identification of Distinct Pro-Fibrotic Monocyte and Macrophage Subsets in Systemic Sclerosis
Background/Purpose: Chronic inflammation may modulate the balance of classical, intermediate and non-classical monocyte subsets (defined by CD14/CD16 expression)1. Monocytes are heterogeneous and subsets can be…Abstract Number: 1969 • 2019 ACR/ARP Annual Meeting
FOXO1 Is Required for Human Osteoclast Differentiation
Background/Purpose: Dysregulation of osteoclast differentiation and function is a feature of inflammatory arthropathies (IA). Multiple genes and signalling pathways have been associated with regulation of…Abstract Number: 29 • 2019 ACR/ARP Annual Meeting
Therapeutic Anti-TNF Biologic Agents Exhibit Functional Differences in Blocking TNF-induced Effects on Human Monocytes In Vitro
Background/Purpose: Therapeutic anti-TNF biologic agents can be distinct in their structure and/or in their binding to TNF. Whether these differences affect the functional properties of…Abstract Number: 55 • 2019 ACR/ARP Annual Meeting
A Novel Subclass of Intravascular Non-classical, Tissue Resident Synovial Monocyte Is Critical for Rheumatoid Arthritis Pathogenesis
Background/Purpose: There are at least three populations of circulating monocytes; classical, intermediate and non-classical. We demonstrated that circulating non-classical monocytes are required for the effector…Abstract Number: 1008 • 2018 ACR/ARHP Annual Meeting
Presence of a Specific Defect in M2 Polarization of Blood Monocytes from Patients with Rheumatoid Arthritis, Associated with Increased microRNA-155
Background/Purpose: Macrophages contribute in situ to the RA pathogenesis. Two distinct states of polarization for macrophages have been recognized: the classically activated macrophage phenotype (M1),…Abstract Number: 1100 • 2018 ACR/ARHP Annual Meeting
The Frequencies and Molecular Profiles of CD16+ Monocyte Subsets in Patients with Systemic Lupus Erythematosus, Primary Antiphospholipid Syndrome, and Antiphospholipid Syndrome with Lupus, Identify Specific Clinical Features of These Diseases
Background/Purpose: This study, developed within the IMI-JU project PRECISESADS framework, aimed to determine the enrichment on CD14+ and CD16+ monocyte subpopulations in SLE, APS and…Abstract Number: 1466 • 2018 ACR/ARHP Annual Meeting
Altered Count of NK Cells and Non-Classical Monocyte Subpopulation in the Pre-Clinical Phase of Rheumatoid Arthritis
Background/Purpose: Anti-citrullinated protein antibodies (ACPA) are detectable long before the manifestation of rheumatoid arthritis (RA). EULAR provided a clinical definition of individuals with arthralgia suspicious…Abstract Number: 2090 • 2018 ACR/ARHP Annual Meeting
Identification of a Role for Monocytes in Murine Lupus Associated Diffuse Alveolar Hemorrhage By Mass Cytometry
Background/Purpose: Diffuse alveolar hemorrhage (DAH) is a life-threatening pulmonary complication of systemic lupus erythematosus. The inciting pathology is thought to be pulmonary capillaritis but the…Abstract Number: 1567 • 2017 ACR/ARHP Annual Meeting
A Mitogen-Associated Protein Kinase (MAPK) Associated Kinase 2 Inhibitor Decreases in Vitro Th17 and Monocyte Inflammatory Responses in Spondyloarthritis
Background/Purpose: The current biologic treatment for Ankylosing Spondylitis (AS) and Psoriatic Arthritis (PsA) are limited to TNF-a inhibitors (TNFi) and, more recently, IL-17A monoclonal antibodies.…Abstract Number: 1680 • 2017 ACR/ARHP Annual Meeting
Higher Baseline Monocyte Count Is Associated with More Extensive Skin Involvement and Higher Mortality in Systemic Sclerosis
Background/Purpose: Macrophages are the primary inflammatory cell type present in the systemic sclerosis (SSc) skin. Circulating monocytes can give rise to profibrotic inflammatory cells such…Abstract Number: 1948 • 2017 ACR/ARHP Annual Meeting
TNF-α Overrides the Ability of RANK Ligand to Induce Osteoclast Differentiation of Classical Circulating Precursors
Background/Purpose: TNF-α is well known to be involved in inflammatory-induced bone destruction. This is widely supported by clinical studies showing reduced bone pathology after anti-TNF-α…Abstract Number: 135 • 2017 Pediatric Rheumatology Symposium
Epigenetic Profiling Of Juvenile Idiopathic Arthritis (JIA) Synovial Fluid Monocytes Points Towards a Role For Monocytes In Bone Damage
Background/Purpose: Juvenile Idiopathic Arthritis (JIA) is a multifactorial autoimmune disease characterized by the accumulation of various immune cells, including monocytes, in the joint synovial fluid…
