Structure and biological functions of human IgD. IV. Ontogeny of human serum immunoglobulin D(IgD) as related to IgG, IgA and IgM. 1975

G A Leslie, and R H Lopez Correa, and J N Holmes

The ontogeny of serum IgG, IgA, IgM and IgD in 312 members of a southern United States population was studied. Circulating IgD was found in all adolescents and in 97% of the adults tested. IgD levels increased until adult life. Females had statistically significantly higher levels of Igtd than did the males of their respective age groups. The children investigated showed an accelerated development of adult levels of all immunoglobulins, particularly IgG, IgM and IgD. These departures from previously reported norms emphasize the importance of regional variability and demonstrate the necessity for characterizing local patterns of humoral immunologic development. Our total lack of knowledge concerning the biological function of IgD could be corrected if more laboratories would measure IgD as part of their routine immunoglobulin screening programs.

UI	MeSH Term	Description	Entries
D007070	Immunoglobulin A	Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions.	IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007072	Immunoglobulin D	An immunoglobulin which accounts for less than 1% of plasma immunoglobulin. It is found on the membrane of many circulating B LYMPHOCYTES.	IgD,IgD1,IgD2
D007074	Immunoglobulin G	The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.	Gamma Globulin, 7S,IgG,IgG Antibody,Allerglobuline,IgG(T),IgG1,IgG2,IgG2A,IgG2B,IgG3,IgG4,Immunoglobulin GT,Polyglobin,7S Gamma Globulin,Antibody, IgG,GT, Immunoglobulin
D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D007106	Immune Sera	Serum that contains antibodies. It is obtained from an animal that has been immunized either by ANTIGEN injection or infection with microorganisms containing the antigen.	Antisera,Immune Serums,Sera, Immune,Serums, Immune
D007223	Infant	A child between 1 and 23 months of age.	Infants
D007231	Infant, Newborn	An infant during the first 28 days after birth.	Neonate,Newborns,Infants, Newborn,Neonates,Newborn,Newborn Infant,Newborn Infants

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011159	Population Surveillance	Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.	Surveillance, Population
