Summary
This review explores the role of cytokines in polymyositis and dermatomyositis, highlighting their impact on immune cells and muscle tissue. Cytokines like interleukin-1 and tumor necrosis factor-alpha are key players, suggesting potential new therapeutic targets.
Area of Science:
- Immunology
- Pathology
- Rheumatology
Background:
- Polymyositis and dermatomyositis are inflammatory muscle diseases.
- Cytokines are crucial mediators in immune responses.
Purpose of the Study:
- To review the role of cytokines in the pathogenesis of polymyositis and dermatomyositis.
- To explore cytokines as potential therapeutic targets.
Main Methods:
- Literature review of studies on cytokine response in myositis.
- Analysis of cytokine involvement in inflammatory pathways.
Main Results:
- Key cytokines like interleukin-1 and tumor necrosis factor-alpha are found in myositis samples.
- Cytokines influence inflammatory cell migration, differentiation, and maturation.
- Muscle cells actively participate in the inflammatory process via cytokine signaling.
Conclusions:
- Cytokines are central to the pathogenesis of polymyositis and dermatomyositis.
- Muscle cells contribute to a self-sustaining inflammatory response.
- Targeting cytokines offers a promising therapeutic strategy for myositis.

01:28Inflammatory Response
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

01:21Myocarditis I: Introduction
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
01:24T Cell Types and Functions
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.

01:27Myocarditis II: Clinical Features and Diagnostic Tests
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
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 (Humira),...
01:20The JAK-STAT Signaling Pathway
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...
