Types of Intermediate Filaments01:31

Types of Intermediate Filaments

3.8K
The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

7.8K
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.

Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

320
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Area of Science:

  • Immunology
  • Molecular Biology
  • Oncology

Background:

  • The type-I interferon (IFN) system is a critical defense against viral infections.
  • IFN-induced tetratricopeptide repeat (IFIT) proteins are key mediators of antiviral responses.
  • Emerging research highlights IFIT protein roles beyond viral infections, including cancer and sepsis.

Purpose of the Study:

  • To explore the multifaceted roles of IFIT proteins in various pathologies.
  • To investigate the dual function of IFIT proteins in oral squamous cell carcinoma (OSCC) metastasis.
  • To examine the implications of IFIT proteins in viral and bacterial/fungal sepsis.

Main Methods:

  • Review and synthesis of existing literature on IFIT protein function.
  • Analysis of IFIT protein expression patterns in different disease contexts.
  • Exploration of therapeutic strategies targeting IFIT proteins.

Main Results:

  • IFIT1 and IFIT3 promote OSCC metastasis, while IFIT2 has an inhibitory effect.
  • The role of IFIT2 in bacterial/fungal sepsis is complex and requires further investigation.
  • IFIT proteins are vital for viral clearance in viral sepsis, but pathogens like SARS-CoV-2 can evade IFN responses.

Conclusions:

  • Understanding IFIT protein roles in diverse pathologies is essential for developing targeted therapies.
  • Modulating IFIT expression presents potential therapeutic avenues for cancer and sepsis.
  • Targeting IFIT proteins could improve outcomes in viral infections and associated complications like septic shock.
