Summary
Cellular restriction factors are key to innate immunity against flaviviruses like Dengue and Zika. This review highlights recent discoveries of these antiviral proteins and their mechanisms against flavivirus infection.
Area of Science:
- Virology
- Immunology
- Cell Biology
Background:
- Flaviviruses are arthropod-borne RNA viruses causing significant human diseases.
- Emerging and re-emerging flaviviruses (DENV, ZIKV, WNV, TBEV, YFV) pose global health challenges.
- Cellular restriction factors are crucial components of the innate immune response against viral infections.
Purpose of the Study:
- To review recent advancements in identifying and characterizing cellular restriction factors against flaviviruses.
- To provide an overview of the known flavivirus restrictome and emerging mechanisms of action.
Main Methods:
- Literature review of recent studies on flavivirus-host interactions.
- Focus on specific restriction factors including IFI6, Schlafen 11, FMRP, OAS-RNase L, RyDEN, TRIM proteins, and viperin.
Main Results:

14.5K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

5.5K
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...

Restriction enzymes are bacterial enzymes used to cut DNA in a sequence-specific manner. To cleave DNA, they bind to specific palindromic sequences called restriction sites. Such palindromic DNA sequences or inverted repeats are commonly found in regions of functional significance, such as the origin of replication, gene operator sites, and regions containing transcription termination signals.

49.0K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...
