Abstract
Objective:
To study the autocrine function of tumor necrosis factor (TNF) in glomerular mesangial cells (MC) and the action of TNF on MC.
Methods:
Cultured rat and human MC were studied by RT-PCR, in situ hybridization and immunohistochemical methods.
Results:
The expression of both TNF and TNF receptor mRNA and protein synthesis in MC were manifested.
Conclusion:
(1) MC is the target cell for TNF, MC have specific cell surface receptor to TNF. (2) TNF acts on MC through both autocrine and paracrine mechanism.
Insights
Glomerular mesangial cells (MC) produce and respond to tumor necrosis factor (TNF), indicating an autocrine and paracrine role for TNF in kidney cell function.
Area of Science:
- Immunology
- Nephrology
- Cell Biology
Context:
- Glomerular mesangial cells (MC) play a crucial role in kidney function.
- Tumor necrosis factor (TNF) is a pro-inflammatory cytokine with diverse cellular effects.
Purpose:
- To investigate the autocrine function of TNF in MC.
- To elucidate the mechanisms by which TNF influences MC.
Summary:
- MC express both TNF and TNF receptor mRNA and protein.
- MC are target cells for TNF, possessing specific cell surface receptors.
- TNF exerts its effects on MC via autocrine and paracrine signaling pathways.
Impact:
- This study reveals a novel autocrine loop for TNF in MC.
- Understanding TNF's action on MC is vital for developing targeted therapies for kidney diseases.
