Retrovirus Life Cycles01:10

Retrovirus Life Cycles

46.5K
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...

Immune Response Against Viral Pathogens

888
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...

Viral Recombination00:57

Viral Recombination

23.7K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Retroviruses02:33

Retroviruses

12.6K
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

84
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...

Area of Science:

  • Neurology
  • Virology
  • Infectious Diseases

Background:

  • Viral infections can directly impact the central nervous system (CNS), leading to serious conditions like encephalitis, myelitis, and meningitis.
  • Acute encephalopathy, often linked to viral respiratory infections, presents a distinct neurological challenge.
  • Understanding the specific viral agents and their associated CNS manifestations is crucial for diagnosis and treatment.

Purpose of the Study:

  • To categorize and outline various viral central nervous system (CNS) infections.
  • To provide an overview of specific viral etiologies for encephalitis/myelitis, meningitis, and encephalopathy.
  • To consolidate information on key viral CNS pathogens for clinical and research reference.

Main Methods:

  • Literature review and synthesis of existing research on viral CNS infections.
  • Categorization of viral infections based on clinical presentation (encephalitis/myelitis, meningitis, encephalopathy).
  • Identification and description of specific viruses associated with each category.

Main Results:

  • Herpes encephalitis, poliomyelitis, enterovirus A71 brainstem encephalitis/myelitis, and enterovirus D68 paralytic myelitis are identified as acute encephalitis/myelitis.
  • Enteroviral meningitis and mumps meningitis are classified as acute viral meningitis.
