Summary
Shrimp possess innate immune pathways, including Toll, IMD, and JAK/STAT, crucial for defending against microbial infections and viruses like WSSV. Further research is needed to fully understand these complex immune responses.
Area of Science:
- * Invertebrate immunology
- * Molecular biology
- * Aquaculture pathology
Background:
- * Innate immunity is the primary defense against pathogens in animals.
- * Signal transduction pathways like Toll, IMD, and JAK/STAT regulate invertebrate immune responses.
- * Understanding shrimp immune pathways is vital for disease control in aquaculture.
Purpose of the Study:
- * To review and propose the existence of Toll, IMD, and JAK/STAT pathways in shrimp.
- * To investigate the role of these pathways in shrimp immune responses to pathogens, particularly WSSV.
- * To highlight the importance of functional studies for elucidating shrimp innate immunity.
Main Methods:
- * Literature review and comparative analysis of known invertebrate immune pathways.
- * Identification and cloning of homologous genes/proteins in shrimp.
- * Analysis of gene transcription levels following pathogen challenge (e.g., WSSV).
Main Results:
- * Evidence suggests the presence of Toll, IMD, and JAK/STAT pathways in shrimp.
- * Shrimp Toll pathway components are responsive to Gram-positive bacteria, Gram-negative bacteria, and WSSV.
- * Components of IMD and JAK/STAT pathways were identified, with roles in bacterial and viral defense, indicating pathway crosstalk.
Conclusions:
- * Toll, IMD, and JAK/STAT pathways are likely functional in shrimp, playing significant roles in innate immunity.
- * These pathways are involved in responses to both bacterial and viral infections, including WSSV.
- * Further functional studies are essential to comprehensively understand shrimp immune signaling and improve disease management strategies.

01:20The 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...
01:22Diversity in Cell Signaling Responses
The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.

01:19Interactions Between Signaling Pathways
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...

02:26NF-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.

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
