AITRL, also known as Activation-Inducible TNF-Related Ligand, is a member of the tumor necrosis factor (TNF) superfamily. It is also referred to as GITR Ligand (GITRL) due to its interaction with the Glucocorticoid-Induced TNF Receptor (GITR). AITRL is classified as a cytokine, which plays a crucial role in immune regulation and inflammation .
Key Biological Properties: AITRL is a transmembrane protein with a conserved TNF domain. It is a 14.4 kDa protein containing 127 amino acid residues .
Expression Patterns: AITRL is expressed in various cell types, including endothelial cells and antigen-presenting cells .
Tissue Distribution: The expression of AITRL is predominantly found in immune-related tissues, such as the spleen, lymph nodes, and thymus .
Primary Biological Functions: AITRL plays a significant role in the regulation of immune responses. It is involved in the activation, proliferation, and differentiation of T cells.
Role in Immune Responses: AITRL can activate NF-kappa-B, induce both pro- and anti-apoptotic effects, inhibit the suppressive activity of regulatory T cells, and co-stimulate responder T cells through GITR.
Pathogen Recognition: AITRL is involved in the recognition and response to pathogens by modulating the activity of immune cells.
Mechanisms with Other Molecules and Cells: AITRL interacts with its receptor, GITR, leading to downstream signaling events that modulate immune cell function.
Binding Partners: The primary binding partner of AITRL is GITR, which is expressed on CD4+ CD25+ regulatory T cells.
Downstream Signaling Cascades: The binding of AITRL to GITR promotes the activation of NF-kappa-B and various mitogen-activated protein kinases, leading to immune cell activation and cytokine production.
Expression and Activity Control: The expression of AITRL is regulated by various factors, including cytokines and transcription factors .
Transcriptional Regulation: The transcription of AITRL is controlled by specific transcription factors that respond to immune signals .
Post-Translational Modifications: AITRL undergoes post-translational modifications, such as glycosylation, which can affect its stability and function .
Biomedical Research: AITRL is used in research to study immune regulation and inflammation .
Diagnostic Tools: AITRL can be used as a biomarker for certain immune-related conditions .
Therapeutic Strategies: AITRL is being explored as a potential target for therapeutic interventions in autoimmune diseases, allergic reactions, and cancer.
Development: AITRL plays a role in the development of the immune system by influencing the differentiation and maturation of T cells .
Aging: The expression and function of AITRL may change with age, affecting immune responses in older individuals .
Disease: Dysregulation of AITRL signaling has been implicated in various immune-related disorders, including autoimmune diseases and cancer.
