Insights

Apoptotic cell therapy shows promise for rheumatoid arthritis (RA) by reducing inflammation. This approach may complement existing treatments like methotrexate and TNF inhibitors, offering a potential new treatment for RA patients.

Area of Science:

  • Immunology
  • Rheumatology
  • Cell Therapy

Background:

  • Rheumatoid arthritis (RA) is a chronic immune-mediated disease.
  • Current treatments include conventional synthetic drugs (e.g., methotrexate) and targeted biological agents.
  • Cell-based therapies, particularly those using mesenchymal stroma cells, are under development for RA.

Purpose of the Study:

  • To review the development of apoptotic cell-based therapy for arthritis.
  • To discuss the potential transfer of this therapy to rheumatoid arthritis patients.
  • To explore the use of apoptotic cell-derived factors in RA treatment.

Main Methods:

  • Review of existing literature on apoptotic cell therapy in experimental arthritis models.
  • Analysis of evidence for anti-inflammatory properties of early-stage apoptotic cells.
  • Examination of safety and efficacy data from related clinical applications (e.g., graft-vs.-host disease prevention).

Main Results:

  • Apoptotic cells possess direct and indirect anti-inflammatory properties.
  • Administration of apoptotic cells shows therapeutic potential in experimental arthritis.
  • Apoptotic cells may synergize with standard RA treatments like methotrexate and TNF inhibitors.
  • Apoptotic cell infusion has a good safety profile in preventing graft-vs.-host disease.

Conclusions:

  • Apoptotic cell-based therapy is a promising innovative treatment for rheumatoid arthritis.
  • This approach may offer benefits when used alongside conventional RA therapies.
  • Apoptotic cell-derived factors, such as secretome and liposomes, warrant further investigation for RA treatment.

The JAK-STAT Signaling Pathway01:20

The 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...
Inflammatory Response01:28

Inflammatory 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,...
T Cell Types and Functions01:24

T 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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

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 Disease...

Drugs 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),...
