Summary
Glucocorticoid-induced TNFR-related protein (GITR) and its ligand (GITRL) modulate immune responses. Their interaction is key in autoimmune diseases, impacting T cells and myeloid cells.
Area of Science:
- Immunology
- Cell Biology
- Molecular Medicine
Background:
- Glucocorticoid-induced TNFR-related protein (GITR) is a TNFR superfamily member expressed on immune cells.
- GITR ligand (GITRL) is found on antigen-presenting and endothelial cells.
- GITR engagement influences innate and adaptive immunity.
Purpose of the Study:
- To review the effects of GITR/GITRL activation on immune cells.
- To summarize the role of GITR/GITRL in autoimmune diseases.
- To elucidate the mechanisms underlying GITR/GITRL's role in autoimmunity.
Main Methods:
- Literature review of GITR/GITRL interactions.
- Analysis of GITR/GITRL effects on effector T cells, regulatory T cells (Tregs), and myeloid cells.
- Examination of molecular mechanisms in autoimmune disease pathogenesis.
Main Results:
- GITR/GITRL activation impacts effector T cells, Tregs, and myeloid cells.
- Evidence links GITR/GITRL interaction to tumor, inflammation, and autoimmune disease pathogenesis.
- Specific mechanisms of modulation in autoimmune conditions are detailed.
Conclusions:
- GITR/GITRL signaling is a significant factor in immune system regulation.
- Understanding GITR/GITRL pathways offers therapeutic potential for autoimmune diseases.
- Further research into GITR/GITRL mechanisms is warranted for targeted interventions.

01:29Autoimmune Disorders
1.2K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

01:24T Cell Types and Functions
1.8K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

15.0K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

01:20The JAK-STAT Signaling Pathway
10.7K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
322
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
342
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
