Tumor necrosis factor receptors (TNFR1 and TNFR2) are crucial in inflammation and cell death, implicated in various diseases. Targeting their structure and conformational states offers new therapeutic strategies for autoimmune disorders, neurodegenerative diseases, and cancers.
Area of Science:
- Immunology
- Molecular Biology
- Structural Biology
Background:
- Tumor necrosis factor receptors (TNFR1 and TNFR2) mediate critical inflammatory and cell death signals.
- Dysregulation of TNF receptor signaling is linked to autoimmune disorders, neurodegenerative diseases, and cancers.
- Understanding receptor-ligand interactions and structural dynamics is key to modulating these pathways.
Purpose of the Study:
- To review therapeutic strategies targeting TNF receptor signaling pathways.
- To explore the potential of modulating receptor-ligand and receptor-receptor interactions.
- To highlight the role of receptor conformational states as therapeutic targets.
Main Methods:
- Review of available crystal structures of TNF receptors.
- Analysis of structure-function relationships.
- Discussion of allosteric mechanisms and competitive targeting strategies.
Main Results:
- Crystal structures provide insights into therapeutic targeting of TNF receptors.
- Targeting receptor-ligand/receptor-receptor interactions and conformational dynamics can modulate signaling.
- Conformational states act as molecular switches, representing key therapeutic targets.
Conclusions:
- Modulating TNF receptor signaling through structural and conformational targeting holds significant therapeutic potential.
- Knowledge of structure-function relationships aids in drug screening and design.
- Novel receptor-specific modulators can be developed for enhanced pharmacological properties.

Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
