Introduction to Virus

2.3K
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...

Intracellular Movement of Viruses and Bacteria

3.7K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Size and Structure of Viral Genomes

962
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

Retroviruses02:33

Retroviruses

15.5K
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’...

Subviral Agents01:29

Subviral Agents

704
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

  • Infectious Diseases
  • Public Health

Background:

  • Flaviviruses, including tick-borne encephalitis virus (TBEV), pose significant global health risks, causing severe neurological diseases.
  • No specific antiviral treatments currently exist for TBEV, highlighting an urgent need for research and development.
  • Langat virus (LGTV), a related flavivirus, offers a unique model for understanding tick-borne flavivirus biology and potential vaccine strategies.

Purpose of the Study:

  • To review current knowledge on Langat virus (LGTV), focusing on its vector competence, transmission, tropism, pathogenicity, and animal models.
  • To explore the potential of LGTV as a vaccine candidate against TBEV.
  • To identify research gaps and inspire further investigation into LGTV and tick-borne flaviviruses.

Main Methods:

  • Comprehensive literature review of existing studies on LGTV.
  • Analysis of LGTV's vector competence, transmission routes, and host interactions.
  • Evaluation of LGTV's pathogenicity in various animal models.
  • Discussion of LGTV's potential as a vaccine platform for TBEV.

Main Results:

  • LGTV exhibits potential for tick-independent transmission, broadening its epidemiological significance.
  • LGTV infection in animal models can lead to neurological symptoms, similar to TBEV.
  • LGTV's poorly defined host range and distribution warrant further investigation, especially in the context of climate change.

Conclusions:

  • LGTV is an understudied tick-borne flavivirus with unique characteristics valuable for fundamental research.
  • LGTV holds promise as a vaccine candidate for TBEV, necessitating further research into its immunogenicity and efficacy.
  • Understanding LGTV can advance knowledge of tick-borne flavivirus biology and inform strategies for disease prevention and control.
