Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

2.4K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

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.

Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

1.4K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

Leaky Scanning02:28

Leaky Scanning

5.1K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

T Cell Types and Functions01:24

T Cell Types and Functions

966
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Summary

The NLRP3 inflammasome plays a dual role in infectious diseases, aiding host defense but also causing damaging inflammation when overactivated. Inhibitors targeting this inflammasome show promise for new treatments.

Area of Science:

  • Immunology
  • Molecular Biology
  • Infectious Diseases

Background:

  • The Nod-like receptor family pyrin domain containing 3 (NLRP3) inflammasome is a critical protein complex involved in innate immunity.
  • NLRP3 inflammasome activation triggers inflammation via pyroptosis and the release of IL-1β and IL-18, crucial in host defense against pathogens.
  • Its role in infectious diseases is complex, acting as both a protective mechanism and a driver of pathology.

Purpose of the Study:

  • To provide a comprehensive review of the NLRP3 inflammasome's multifaceted role in the context of infectious diseases.
  • To explore the dual effects of NLRP3 inflammasome activation: its protective functions and its contribution to inflammatory damage.

Main Results:

  • The NLRP3 inflammasome is essential for host defense in infectious diseases, mediating crucial inflammatory responses.
