Insights

Nuclear factor kappa B (NF-kappa B) regulates intercellular adhesion molecule-1 (ICAM-1) expression in human mesangial cells stimulated by interleukin-1 beta (IL-1 beta). This signaling pathway is involved in glomerular immune-inflammatory processes.

Area of Science:

  • Molecular Biology
  • Immunology
  • Cell Biology

Context:

  • Interleukin-1 beta (IL-1 beta) is a key inflammatory cytokine.
  • Intercellular Adhesion Molecule-1 (ICAM-1) plays a role in immune cell adhesion and inflammation.
  • Human Mesangial Cells (HMC) are crucial components of the glomerulus.

Purpose:

  • To investigate the role of nuclear factor kappa B (NF-kappa B) in mediating IL-1 beta-induced ICAM-1 expression in HMC.
  • To elucidate the signaling pathway involved in glomerular inflammation.

Summary:

  • Interleukin-1 beta (IL-1 beta) rapidly activates nuclear factor kappa B (NF-kappa B) and upregulates ICAM-1 expression at both mRNA and protein levels in HMC.
  • Inhibition of NF-kappa B activation using TPCK significantly blocked IL-1 beta-induced ICAM-1 expression.
  • Electrophoresis mobility shift assay (EMSA), Northern Blot, and Cell ELISA were used to measure NF-kappa B activation and ICAM-1 expression.

Impact:

  • NF-kappa B acts as a signaling factor for IL-1 beta-stimulated ICAM-1 expression in HMC.
  • This finding suggests a mechanism by which NF-kappa B modulates immune-inflammatory processes in glomerular diseases.

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

NF-κB-dependent Signaling Pathway

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.

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
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...
Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Immunoglobulin-like Cell Adhesion Molecules01:31

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
