Definition

Noun: - A class of proteins produced in lymph tissue in vertebrates and that function as antibodies in the immune response: It refers to a specific type of globulin protein, also known as immunoglobulin, which is a crucial component of the body's adaptive immune system. These proteins are produced by plasma cells and are capable of specifically recognizing and binding to antigens like bacteria and viruses to help neutralize them.

Usage Examples

• Noun:
  • The doctor administered immune gamma globulin to boost the patient's passive immunity.
  • A deficiency in immune gamma globulin can make an individual more susceptible to infections.

Advanced Usage

• Therapeutic Use: The term is often used in medical contexts to refer to preparations of these antibodies used for treatment or prevention of diseases.
  • Immune gamma globulin is a standard treatment for certain primary immunodeficiency disorders.

Variants and Related Words

• Immunoglobulin (Ig): The more common scientific term, which is synonymous with immune gamma globulin.
  • There are five main classes of immunoglobulins: IgA, IgD, IgE, IgG, and IgM.
• Gamma Globulin: A broader term that can refer to the fraction of blood serum containing most antibodies, including but not limited to immune gamma globulin.
  • The gamma globulin fraction was separated via electrophoresis.
• Antibody: A general term for a protein produced by the immune system to identify and neutralize foreign objects.
  • The test detects antibodies specific to the virus.

Synonyms

• Immunoglobulin
• Antibody (in a general sense, though not all antibodies are gamma globulins, all immune gamma globulins are antibodies)

Related Phrases

  • The patient receives monthly IVIG infusions.
• Hyperimmune Globulin: A preparation containing high titers of antibodies against a specific pathogen.
