Autoimmune Disorders01:29

Autoimmune Disorders

385
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Retroviruses02:33

Retroviruses

12.2K
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’...

Mechanisms of Retrovirus-induced Cancers

5.0K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

11.4K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

45.6K
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 Pathogens01:29

Immune Response Against Viral Pathogens

745
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...

Summary

Human endogenous retroviruses (HERVs) integrated into the genome can cause disease. Deregulated HERV expression can trigger immune responses, potentially leading to autoimmune disorders and inflammation.

Area of Science:

  • Immunology
  • Genetics
  • Molecular Biology

Background:

  • Human endogenous retroviruses (HERVs) are remnants of ancient retroviral infections integrated into the human genome.
  • Under normal conditions, HERVs can be epigenetically regulated and contribute to physiological functions.
  • Aberrant HERV expression, triggered by external factors, is linked to various pathologies.

Purpose of the Study:

  • To explore the role of HERV expression in human health and disease.
  • To investigate the mechanisms by which HERVs influence immune responses.
  • To understand the contribution of HERVs to inflammation and autoimmunity.

Main Methods:

  • Review of existing literature on HERV biology and their association with diseases.
  • Analysis of epigenetic regulation of HERV expression.
  • Examination of immune system activation in response to HERV determinants.

Main Results:

  • HERV sequences can be immunogenic and are epigenetically controlled.
  • Reprogrammed HERV expression can disrupt immune tolerance.
  • Deregulated HERVs mobilize both innate and adaptive immune systems.

Conclusions:

  • HERV expression plays a significant role in the pathogenesis of autoinflammatory and autoimmune disorders.
  • HERV-induced immune responses can exacerbate tissue-specific and systemic diseases.
  • Further mechanistic studies are crucial to fully understand HERV impact on inflammation and autoimmunity.
