Homocitrullinated Peptides Drive Pro‐Inflammatory T Cell Responses in a Humanized Mouse Model of Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Anti‐homocitrullinated protein/peptide antibodies are specific to rheumatoid arthritis (RA) and predictive of worse prognosis, suggesting a pathogenic role for autoreactivity to homocitrullinated peptides (HomoCitP). However, T cell responses to HomoCitP remain largely unexplored.

Identification of antigens in BAL fluid in Sarcoidosis

Revista Portuguesa de Pneumologia, 2007
Activated T lymphocytes of the Th-1 type are typically accumulated in the lungs of patients with sarcoidosis, and there they may recognize specific sarcoidosis antigens, presented by antigen presenting cells such as dendritic cells and/or alveolar ...

The Role of IgM Anti‐acetylated Protein Antibodies and B Cells in the Origin of Antimodified Protein Autoimmunity in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) is characterized by anti‐modified protein antibodies (AMPAs), including anti‐citrullinated protein antibodies (ACPA), anti‐carbamylated protein antibodies (anti‐CarP), and anti‐acetylated protein antibodies (AAPA). In contrast to other AMPAs, AAPA IgM is found in healthy individuals, raising questions about its role ...

Challenges of monocyte HLA-DR targeted immunomodulation in sepsis—a prospective observational cohort study

Frontiers in Immunology
IntroductionReduced monocyte HLA-DR expression, a hallmark of immunosuppression in sepsis, is associated with infectious complications and mortality. Therapeutic strategies, including IFN-γ, have been used to restore monocyte HLA-DR and immune function ...

The relationship between human leukocyte antigens (HLA) and renal cell carcinoma

Biomolecules & Biomedicine, 2010
Etiologies of Renal Cell Carcinoma (RCC) are not clear despite of the fact that many risk factors have been suggested. Especially in high stages RCC can affect the immune system in various ways.

Dnmt3a Mutations Limit Normal and Autoreactive CD4+ T Follicular Helper Responses and Attenuate T Cell–Driven Joint Inflammation

Arthritis &Rheumatology, EarlyView.
Objective Somatic DNMT3A mutations are the most common drivers of clonal hematopoiesis in patients with rheumatoid arthritis (RA) and have been associated with seropositive disease and increased markers of inflammation. These mutations are predominantly hypomorphic or dominant‐negative, reducing DNMT3A function.

Flow Cytometric Analysis of T, B, and NK Cells Antigens in Patients with Mycosis Fungoides

Journal of Immunology Research, 2015
We retrospectively analyzed the clinicopathological correlation and prognostic value of cell surface antigens expressed by peripheral blood mononuclear cells in patients with mycosis fungoides (MF). 121 consecutive MF patients were included in this study.

Differential Expression of HLA-DR, DQ, and DP Antigens in Primary and Metastatic Melanoma [PDF]

, 1988
Fifty-five primary and 33 metastatic surgically removed melanoma lesions were stained in indirect immunoperoxidase with anti HLA-DR, DQ, and DP monoclonal antibodies and with the monoclonal antibody CL203.4 to a 96-K melanoma associated antigen (MAA ...

Deep Immunophenotyping Reveals Distinct Immune Signatures in Axial Spondyloarthritis and Psoriatic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) are overlapping yet distinct conditions within the SpA spectrum. As divergent immunophenotypes may influence disease course and therapeutic response, we compared immune cell subsets, cytokine profiles, and inflammatory mediators.

Type I Interferon Drives Dysfunction of a Distinct CD8+ HLA‐DRB1+ T Cell Subset in Systemic Lupus Erythematosus

Arthritis &Rheumatology, EarlyView.
Objective Systemic lupus erythematosus (SLE) is characterized by type I interferon (IFN) signaling and adaptive immune dysregulation. We previously identified hypomethylation of HLA‐DRB1 and STAT1 in SLE CD8+ T cells, enabling aberrant IFN‐driven HLA‐DRB1 expression and expansion of a distinct CD8+ T cell subset. This study characterized CD8+ HLA‐DRB1+
