Mechanisms of Retrovirus-induced Cancers

Mechanisms of Retrovirus-induced Cancers

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...

Immune Response Against Viral Pathogens

Immune Response Against Viral Pathogens

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...

Cytomegalovirus Disease

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Respiratory Syncytial Virus Disease

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...

Encephalitis ll: Pathophysiology

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

The virus hypothesis in systemic lupus erythematosus

Annals of Internal Medicine

|November 1, 1975

Summary

Type-C viruses are implicated in systemic lupus erythematosus. Recent findings suggest enhanced type-C virus expression may play a role in this autoimmune disease.

Area of Science:

Virology
Immunology
Rheumatology

Background:

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease.
The etiology of SLE remains incompletely understood.
Type-C viruses have been investigated as potential causative agents.

Purpose of the Study:

To review the potential pathogenetic roles of viruses, particularly type-C viruses, in SLE.
To summarize experimental and human studies investigating viral involvement in SLE.

Main Methods:

Literature review of experimental and human studies on viral etiology of SLE.
Analysis of evidence for type-C virus expression in SLE patients.

Main Results:

Previous experimental attempts to link specific viruses to SLE have yielded negative results.

Recent evidence indicates enhanced type-C virus expression in SLE.

Conclusions:

While definitive proof is lacking, type-C viruses remain prime candidates for SLE etiology.
Further research is warranted to elucidate the role of enhanced type-C virus expression in SLE pathogenesis.
