Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

725
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Rous Sarcoma Virus (RSV) and Cancer

5.5K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Conjugated Proteins

18.7K
Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

988
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...

Area of Science:

  • Immunology
  • Virology
  • Public Health

Background:

  • Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) may possess unique superantigen-like properties.
  • Superantigens are known to induce an excessive immune response, potentially leading to severe health consequences.
  • Understanding these properties is critical given the virus's airborne nature and potential for reinfection.

Purpose of the Study:

  • To investigate the potential superantigenic nature of SARS-CoV-2.
  • To assess the implications of widespread transmission of a potential superantigenic pathogen.
  • To inform necessary vaccination and public health strategies.

Main Methods:

  • Comparative analysis of SARS-CoV-2's genetic makeup against other coronaviruses.
  • Review of existing literature on superantigen mechanisms and immune responses.
  • Epidemiological assessment of clinical outcomes in relation to viral characteristics.

Main Results:

  • Identification of a unique superantigen-like motif in SARS-CoV-2, absent in other related coronaviruses.
  • Correlation between SARS-CoV-2 infection and clinical manifestations resembling superantigen-induced responses.
  • Evidence suggesting potential for immune system overdrive due to the identified motif.

Conclusions:

  • SARS-CoV-2 may function as a superantigen or trigger a superantigenic host response, contributing to its pathogenicity.
  • Urgent research is needed to quantify long-term health risks associated with widespread transmission.
  • Public health policies and vaccination strategies must consider the potential superantigenic properties of SARS-CoV-2 for effective control and prevention of repeat exposures.
