Summary
Listeria monocytogenes infection triggers the inflammasome immune response. However, the pathogen inhibits this pathway, necessitating further research for therapeutic strategies against listeriosis.
Area of Science:
- Immunology
- Microbiology
- Pathogenesis
Background:
- Listeria monocytogenes is a dangerous foodborne pathogen causing listeriosis.
- The inflammasome is a key innate immune complex controlling infections.
- L. monocytogenes infection activates inflammasomes via pathogen-associated molecular patterns (PAMPs).
Purpose of the Study:
- To review inflammasome activation mechanisms by L. monocytogenes.
- To discuss the inflammasome pathway's role in L. monocytogenes pathogenesis.
- To explore applications of inflammasome inhibitors.
Main Methods:
- Review of current literature on L. monocytogenes and inflammasome interactions.
- Analysis of molecular mechanisms of inflammasome activation and inhibition.
- Overview of therapeutic strategies targeting the inflammasome pathway.
Main Results:
- L. monocytogenes utilizes toxins like listeriolysin-O and flagellin to activate inflammasomes.
- Excessive inflammasome activation contributes to L. monocytogenes pathogenesis.
- L. monocytogenes has evolved mechanisms to evade inflammasome-mediated immunity.
Conclusions:
- Understanding inflammasome activation is vital for deciphering L. monocytogenes pathogenicity.
- Inflammasome inhibitors show potential therapeutic applications.
- Further research can identify novel targets to combat L. monocytogenes infections.

01:20The JAK-STAT Signaling Pathway
14.1K
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...

02:26NF-κB-dependent Signaling Pathway
10.8K
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.

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:30Bacterial Signaling
43.6K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

01:28Yeast Signaling
18.5K
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
