Size and Structure of Viral Genomes01:26

Size and Structure of Viral Genomes

959
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...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

50.1K
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...

Retroviruses

15.3K
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’...

Sexually Transmitted Infections

1.4K
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

2.7K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Area of Science:

  • Virology
  • Immunology
  • Molecular Biology

Background:

  • Combinatory antiretroviral therapy (cART) improves survival in HIV-1 patients.
  • Therapy interruption leads to viral replication due to persistent latent HIV-1 reservoirs.
  • Understanding HIV-1 latency mechanisms enables new therapeutic strategies.

Purpose of the Study:

  • To review the 'shock and kill' strategy for purging latent HIV-1.
  • To identify challenges associated with the 'shock and kill' approach.
  • To explore alternative strategies for managing latent HIV-1.

Main Methods:

  • Review of existing literature on HIV-1 latency and therapeutic strategies.
  • Analysis of the 'shock and kill' approach and its limitations.
  • Discussion of emerging therapeutic concepts like 'locking out' proviruses.

Main Results:

  • The 'shock and kill' strategy aims to eliminate latent HIV-1.
  • Significant hurdles impede the efficacy of the 'shock and kill' method.
  • Alternative strategies are being investigated to manage persistent HIV-1.

Conclusions:

  • Latent HIV-1 reservoirs remain a major obstacle in achieving a cure.
  • The 'shock and kill' strategy faces considerable challenges.
  • Locking out latent proviruses presents a promising alternative therapeutic avenue.
