Summary
Tumor necrosis factor (TNF) and its receptors play complex roles in kidney diseases. Understanding their signaling pathways and therapeutic potential is crucial for managing renal disorders.
Area of Science:
- Immunology
- Nephrology
- Molecular Biology
Background:
- Tumor necrosis factor (TNF) is a key mediator of inflammation and immune responses.
- TNF signals through TNFR1 and TNFR2, influencing diverse cellular processes.
- The specific role of TNF and its receptors in renal diseases remains unclear.
Purpose of the Study:
- To review the expression and signaling of TNF receptors (TNFRs) in renal disease models.
- To explore the biological responses mediated by TNF and TNFRs in kidney disorders.
- To discuss the therapeutic implications of TNF-targeting biologics and biomarkers in nephrology.
Main Methods:
- Literature review of animal models of renal diseases.
- Analysis of TNFR expression and signaling pathways.
- Evaluation of TNF-related therapeutic strategies and biomarkers.
Main Results:
- TNF and TNFRs are expressed in various renal disease models.
- Distinct signaling pathways of TNFR1 and TNFR2 contribute to kidney injury and protection.
- TNF biologics and biomarkers show potential but require further investigation in renal disorders.
Conclusions:
- TNF and its receptors are significant players in the pathogenesis of renal diseases.
- Targeting TNF pathways offers potential therapeutic avenues for kidney disorders.
- Further research is needed to optimize TNF-based treatments and diagnostics for nephrology.

7.4K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

2.2K
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

4.4K
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.

01:16TGF - β Signaling Pathway
7.1K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

1.7K
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
