Introduction
Elevated serum IgG: seen in systemic lupus erythematosus, atrophic portal cirrhosis, chronic active hepatitis, rheumatoid arthritis, subacute bacterial endocarditis, IgG myeloma, certain infectious diseases, and IgG monoclonal gammopathies. Immunoglobulin G is the most abundant immunoglobulin in serum, accounting for approximately 75% of the total immunoglobulin content in serum.
With the accelerating pace of modern life, some people often lack physical exercise, leading to a decline in immune function. What is immunoglobulin G?
What Is Immunoglobulin G
Elevated serum IgG levels are observed in systemic lupus erythematosus, atrophic portal cirrhosis, chronic active hepatitis, rheumatoid arthritis, subacute bacterial endocarditis, IgG myeloma, certain infectious diseases, and IgG-type monoclonal gammopathies. Immunoglobulins in the serum account for approximately 75% of the total immunoglobulin content. B lymphocytes transform into plasma cells upon antigen stimulation and produce antibodies capable of specifically binding to corresponding antigens—these are known as immunoglobulins.
Immunoglobulin G (IgG) is the primary component of serum immunoglobulins and plays an important role in human health. IgG has various functions: it can inhibit numerous bacteria and viruses and exerts neutralizing effects, providing defensive and protective benefits to the body. IgG is the only antibody capable of crossing the placenta, helping protect the fetus against infections. However, abnormal immune responses involving immunoglobulins may also trigger allergic reactions and contribute to autoimmune diseases.
In daily life, it's important to engage in regular physical activity. Appropriate exercise can enhance the body's resistance to disease. Additionally, one should consume more protein-rich foods. We hope this information is helpful to you. Wishing you good health and happiness.
