Summary
Shrimp viral diseases impact aquaculture economies. This review updates knowledge on crustacean innate antiviral immunity, highlighting newly identified antiviral molecules and double-stranded RNA (dsRNA)-induced immunity for disease protection.
Area of Science:
- Aquaculture
- Crustacean Immunology
- Virology
Background:
- Viral diseases pose significant economic threats to global shrimp aquaculture industries.
- Research on crustacean immunity has largely overlooked specific antiviral responses, leaving a knowledge gap.
- Understanding innate antiviral immunity is crucial for mitigating disease impacts in farmed crustaceans.
Purpose of the Study:
- To provide an updated review of current knowledge on innate immunity against viral infections in crustaceans.
- To highlight recent advancements in identifying and characterizing antiviral molecules in decapods.
- To discuss the role of double-stranded RNA (dsRNA)-induced antiviral immunity in crustaceans.
Main Methods:
- Literature review of recent studies on crustacean innate immunity and viral diseases.
- Analysis of research on isolated and characterized antiviral molecules from decapods.
- Inclusion of findings on dsRNA-induced antiviral responses in crustaceans.
Main Results:
- Several novel antiviral molecules have been recently isolated and characterized from decapod crustaceans.
- Identification and characterization of these molecules offer potential strategies for disease management.
- Double-stranded RNA (dsRNA) plays a role in inducing antiviral immunity in crustaceans.
Conclusions:
- Recent discoveries of antiviral molecules present promising avenues for protecting shrimp against viral pathogens.
- Further research into these molecules and dsRNA-induced immunity can lead to effective treatment and prevention strategies.
- Enhanced understanding of crustacean antiviral immunity is vital for sustainable aquaculture.

01:23The Antiviral System of Bacteria and Archaea: CRISPR
CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats is a adaptive immune system found in bacteria and archaea that protects against viral infections. This system enables prokaryotic cells to identify, remember, and neutralize foreign genetic elements, primarily bacteriophages, by storing fragments of the invader’s DNA as a genetic memory.The CRISPR immune response begins during an initial infection. Cas (CRISPR-associated) proteins play a central role in this defense.
01:29Immune Response Against Viral Pathogens
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

01:22Antiviral Nucleoside Inhibitors
Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...
02:53CRISPR and crRNAs
Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

01:25Inhibitors Of Virion Release
Viral replication and dissemination rely on efficient mechanisms for host cell entry, genome replication, assembly, and release. Influenza viruses, such as types A and B, are negative-sense single-stranded RNA viruses with a segmented genome, that depend on two critical surface glycoproteins to carry out these processes: hemagglutinin (HA) and neuraminidase (NA). HA initiates infection by binding to sialic acid residues on the surface of host epithelial cells, facilitating receptor-mediated...
01:30Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
