Regulation of T cell response to leishmania antigens by determinants of histocompatibility leukocyte class I and II molecules

Brazilian Journal of Medical and Biological Research, 1998
It has been shown that HLA class I molecules play a significant role in the regulation of the proliferation of T cells activated by mitogens and antigens.

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Alloreactive cytotoxic T lymphocytes generated in the presence of viral- derived peptides show exquisite peptide and MHC specificity [PDF]

, 1993
The nature of alloreactivity to MHC molecules has been enigmatic, primarily because of the observation that allogeneic responses are considerably stronger than syngeneic responses. To better determine the specificity potential of allogeneic responses, we

A Mouse Model of Depression‐Tumor Multimorbidity Reveals the Mechanism of Tumor Growth Accelerated by Depression

Animal Research and One Health, EarlyView.
Depression accelerates tumor growth by dysregulation of tumor immune microenvironment. (A) Modeling methods: Subcutaneous tumor models were established under chronic unpredictable mild stress conditions, including cold swimming, physical restraint, and food/water deprivation, leading to increased tumor growth.

T cells, the Next Big Target in Axial Spondyloarthritis?

Arthritis &Rheumatology, EarlyView.
Axial spondyloarthritis (axSpA) is a chronic inflammatory disease characterized by complex immune dysregulation, with T cells playing a central role in its pathogenesis. In this review, we synthesize current knowledge on diverse T cell subsets in axSpA, their pathogenic mechanisms, and emerging therapeutic strategies targeting these cells. We highlight

Autoreactivity Versus Autoimmunity: Characteristics of Autoantigen‐Specific CD4 T Cells in Rheumatoid Arthritis and Health

Arthritis &Rheumatology, EarlyView.
Objective CD4 T cells specific for citrullinated (cit) peptides are key players in rheumatoid arthritis (RA) immunopathogenesis. Characterizing these cells and identifying features of healthy and RA‐associated autoreactivity will provide valuable insight into disease mechanisms and form the basis of immune state biomarkers to facilitate the next ...

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.

Frecuencia fenotípica y génica de los antígenos HLA en una muestra de la población cubana Phenotypic and genic frequency of HLA antigens in a sample of the Cuban population

Revista Cubana de Hematología, Inmunología y Hemoterapia, 2005
Se realizó un estudio de la frecuencia fenotípica y génica de los antígenos del sistema principal de histocompatibilidad HLA en personas no relacionadas, supuestamente sanas, tomadas como muestra de la población cubana.

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.
