Summary
Nucleotide-binding oligomerization domain 2 (NOD2) has diverse roles in immunity beyond pathogen detection. Understanding its complex functions is key for developing targeted therapies for infections like tuberculosis.
Area of Science:
- Immunology
- Microbiology
Background:
- Nucleotide-binding oligomerization domain 2 (NOD2) is a pattern recognition receptor (PRR) crucial for detecting bacterial muramyl dipeptide (MDP).
- NOD2's functions extend beyond pathogen surveillance, exhibiting complex immunomodulatory effects influenced by context.
- This review synthesizes current knowledge on NOD2's functional plasticity and regulatory mechanisms.
Purpose of the Study:
- To review recent advances in understanding NOD2's functional plasticity.
- To provide insights into NOD2's regulatory mechanisms in immune responses and mycobacterial infections.
Main Methods:
- Literature search of PubMed using keywords: NOD2, signaling pathways, immune homeostasis, autophagy, trained immunity, mycobacterial infection.
- Extraction and summarization of relevant information from research articles and reviews.
Main Results:
- Delineation of MDP-dependent and -independent NOD2 activation pathways.
- Elaboration on NOD2's classical immune responses and noncanonical roles in immune homeostasis (autophagy, TLR synergy, trained immunity).
- Examination of NOD2's role in host defense against mycobacterial infections.
Conclusions:
- Further research is needed to clarify NOD2's diverse roles across different genetic and disease contexts.
- Mechanistic insights into NOD2 function are crucial for developing precision therapeutic strategies targeting this receptor.

9.8K
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.

01:30Assembly of Signaling Complexes
6.5K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.

6.0K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

01:30Bacterial Signaling
40.1K
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...

01:26Antigens Involved in Adaptive Immunity
1.3K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

01:20The JAK-STAT Signaling Pathway
12.1K
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...
