Abstract

Insights

Emerging molecular targets and therapies are being developed for rheumatoid arthritis (RA). This review covers agents targeting CD40, PD-1, GM-CSF, IRAK1/4, Tyk2, B1R, and OX40 for RA treatment.

Area of Science:

  • Rheumatology and immunology research.
  • Drug discovery and development for autoimmune diseases.

Background:

  • Rheumatoid arthritis (RA) pathogenesis involves complex molecular pathways.
  • Current RA treatments can be improved with novel targeted therapies.

Approach:

  • Review of emerging molecular targets for RA treatment.
  • Evaluation of therapeutic agents in clinical and preclinical development.
  • Discussion of targets like CD40, PD-1, GM-CSF, IRAK1/4, Tyk2, B1R, and OX40.

Key Points:

  • CD40/CD40 ligand, PD-1, and GM-CSF are key targets in active RA drug development.
  • Interleukin 1 receptor associated kinases (IRAK1, IRAK4), Tyrosine kinase 2 (Tyk2), Bradykinin receptor 1 (B1R), and OX40 are under investigation.
  • These targets show promise based on RA pathogenesis and efficacy in other autoimmune conditions.

Conclusions:

  • Identifying novel molecular targets is crucial for advancing RA treatment.
  • Multiple therapeutic agents targeting these new pathways are in various stages of development.
  • Continued research into these targets may lead to more effective RA therapies.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF01:24

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...

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...

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

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.
GWAS does not require the identification of the target gene involved in...

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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Transducer Mechanism: Enzyme-Linked Receptors01:27

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
