    Insights

    Respiratory syncytial virus infection in mice caused acute arthritis with joint pathology similar to human rheumatoid arthritis. This suggests viruses may contribute to arthritis development in humans.

    Area of Science:

    • Virology
    • Immunology
    • Rheumatology

    Background:

    • Viral infections are increasingly recognized for their potential to trigger or exacerbate autoimmune conditions.
    • Respiratory syncytial virus (RSV) is a common human pathogen, primarily known for respiratory illness.

    Purpose of the Study:

    • To investigate the potential role of respiratory syncytial virus (RSV) in the development of arthritis.
    • To establish a murine model for studying virus-induced arthritis.

    Main Methods:

    • Experimental infection of mice with respiratory syncytial virus.
    • Pathological examination of joint tissues from infected and control mice.

    Main Results:

    • Eight out of 22 experimentally infected mice developed acute arthritis.
    • Control mice showed no joint abnormalities.
    • Pathological findings in infected mice included pannus formation and joint erosion, mimicking human arthritis, including rheumatoid arthritis.

    Conclusions:

    • Viruses, such as RSV, may play an etiological role in acute and chronic arthritis in humans.
    • This study provides a valuable mouse model for investigating the mechanisms of virus-induced arthritis.

    Viral Mutations00:36

    Viral Mutations

    A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...

    Viruses of Archaea

    Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

    Viral Meningitis

    Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
    Arboviral Encephalitis01:25

    Arboviral Encephalitis

    Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

    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...
    Viral Hepatitis I: Introduction01:28

    Viral Hepatitis I: Introduction

    Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
