Summary
The TWEAK-Fn14 signaling pathway is crucial in tissue injury and autoimmune diseases. Targeting this system shows promise for treating various conditions, including cancer and inflammatory disorders.
Area of Science:
- Immunology
- Molecular Biology
- Pathology
Background:
- Fibroblast growth factor-inducible 14 (Fn14) is a TNF receptor family member induced by tissue injury.
- TWEAK, a TNF ligand, activates Fn14, triggering signaling pathways like NFκB and MAPKs.
- The TWEAK-Fn14 system is implicated in numerous pathologies due to its role in inflammation and tissue damage.
Purpose of the Study:
- To review the molecular and cellular basis of TWEAK/Fn14-related pathological outcomes.
- To discuss preclinical findings on TWEAK and Fn14 targeting drugs.
Main Methods:
- Review of literature on TWEAK-Fn14 signaling.
- Analysis of TWEAK- and Fn14-knockout mouse models.
- Examination of preclinical data on therapeutic targeting.
Main Results:
- The TWEAK-Fn14 system is vital in muscle atrophy, cerebral ischemia, kidney injury, atherosclerosis, and autoimmune diseases.
- Preclinical studies indicate that targeting Fn14 is a viable therapeutic strategy for cancer.
Conclusions:
- The TWEAK-Fn14 pathway plays a significant role in diverse disease pathologies.
- Targeting the TWEAK-Fn14 axis presents a promising therapeutic avenue for various inflammatory and autoimmune conditions, as well as cancer.

01:29Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
01:26Targets for Drug Action: Overview
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

01:24Modified-Release Drug Delivery Systems: Site-Targeted
Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.
01:26Drug Discovery: Overview
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...
01:30Modified-Release Drug Delivery Systems: Stimuli-Activated
Stimuli-activated drug delivery systems are designed to release drugs in response to specific physical, chemical, or biological stimuli. These systems often utilize hydrogels—three-dimensional, hydrophilic polymer networks capable of swelling in aqueous environments and retaining significant fluid volumes. Upon exposure to particular stimuli, these hydrogels undergo structural transitions that allow the embedded drug to be released. Due to this adaptive behavior, such systems are also called...
01:27Transducer 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.
