2022年12月19日 · IgM immunoglobulins are produced by plasma cells as part of the body's adaptive humoral immune response against a foreign pathogen. Resting mature yet naive, B lymphocytes express IgM as a transmembrane antigen receptor that functions as part of the B-cell receptor (BCR).
Immunoglobulin M (IgM) – Properties, Structure and Functions
2024年1月23日 · The immunoglobulin M (IgM) is the largest antibody characterized by the µ heavy chain. Immunoglobulin M is the third most common serum Ig and exists in two forms: a pentamer comprising approximately 10% of normal human serum Ig content and a membrane-bound monomer expressed on the surface of B lymphocytes for antigen recognition.
Immunoglobulin M in Health and Diseases: How Far Have We …
In this review, we explore how IgM structure and BCR signaling shapes B cell development, self and non-self-antigen-specific antibody responses, responses to infectious (such as viruses, parasites, and fungal) and non-communicable diseases (such …

2024年7月19日 · Immunoglobulin M (IgM) holds a pivotal role in the immune system, being one of the first antibodies produced in response to an infection. Its unique structure and functional properties make it crucial for early defense mechanisms against pathogens.
Structure, Function, and Therapeutic Use of IgM Antibodies
Natural immunoglobulin M (IgM) antibodies are pentameric or hexameric macro-immunoglobulins and have been highly conserved during evolution. IgMs are initially expressed during B cell ontogeny and are the first antibodies secreted following exposure to foreign antigens.
IgM Antibodies: Structure, Properties, and Functions
Immunoglobulin M (IgM), the largest pentameric immunoglobulin, is a marker of recent primary infection for some diseases. IgM constitutes 5-10% of serum immunoglobulins in adults. IgM has a half-life of 5 days and can be produced in T independent manner.
