Immunoglobulin d. Medical search

An immunoglobulin which accounts for less than 1% of plasma immunoglobulin. It is found on the membrane of many circulating B LYMPHOCYTES.

The class of heavy chains found in IMMUNOGLOBULIN D. They have a molecular weight of approximately 64 kDa and they contain about 500 amino acid residues arranged in four domains and an oligosaccharide component covalently bound to the Fc fragment constant region.

Autosomal recessive disorder caused by mutations in the mevalonate kinase gene. Because of the mutations cholesterol biosynthesis is disrupted and MEVALONIC ACID accumulates. It is characterized by a range of symptoms, including dysmorphic FACIES, psychomotor retardation, CATARACT, hepatosplenomegaly, CEREBELLAR ATAXIA, elevated IMMUNOGLOBULIN D, and recurrent febrile crises with FEVER; LYMPHADENOPATHY; ARTHRALGIA; EDEMA; and rash.

The domains of the immunoglobulin molecules that are invariable in their amino acid sequence within any class or subclass of immunoglobulin. They confer biological as well as structural functions to immunoglobulins. One each on both the light chains and the heavy chains comprises the C-terminus half of the IMMUNOGLOBULIN FAB FRAGMENT and two or three of them make up the rest of the heavy chains (all of the IMMUNOGLOBULIN FC FRAGMENT)

A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally being called a macroglobulin.

The largest of polypeptide chains comprising immunoglobulins. They contain 450 to 600 amino acid residues per chain, and have molecular weights of 51-72 kDa.

Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.

The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.

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.

The heavy and light immunoglobulin genes are present as gene segments in the germline cells. The completed genes are created when the segments are shuffled and assembled (B-LYMPHOCYTE GENE REARRANGEMENT) during B-LYMPHOCYTE maturation. The gene segments of the human light and heavy chain germline genes are symbolized V (variable), J (joining) and C (constant). The heavy chain germline genes have an additional segment D (diversity).

Polypeptide chains, consisting of 211 to 217 amino acid residues and having a molecular weight of approximately 22 kDa. There are two major types of light chains, kappa and lambda. Two Ig light chains and two Ig heavy chains (IMMUNOGLOBULIN HEAVY CHAINS) make one immunoglobulin molecule.

One of the types of light chains of the immunoglobulins with a molecular weight of approximately 22 kDa.

Biased JH usage in plasma cell immunoglobulin gene sequences from colonic mucosa in ulcerative colitis but not in Crohn's disease. (1/605)

BACKGROUND: Ulcerative colitis is an inflammatory disease of the colonic and rectal mucosa. Autoantibodies have been observed in ulcerative colitis which may have a role in the pathogenesis of the disease. Evidence also suggests that there is an hereditary predisposition towards the disease, although no individual genes have been identified. AIMS: This is a pilot study of immunoglobulin heavy chain genes (IgH) in ulcerative colitis to determine whether they have any particular genetic characteristics which may lead to a better understanding of the disease aetiology. SUBJECTS: Colonic or rectal tissue was obtained from five children with ulcerative colitis. Tissue was also obtained from five children with Crohn's disease and five children who did not have inflammatory bowel disease as controls. METHODS: B cells and IgD+ B cells were identified by immunohistochemistry on frozen sections. Areas of lamina propria containing plasma cells, and areas of IgD+ B cells were microdissected. The immunoglobulin genes were PCR amplified, cloned, and sequenced. Sequences were analysed for content of somatic mutations and composition of heavy chain. RESULTS: An increase in the use of JH6 and DXP'1, and a decrease in the use of JH4, gene segments in immunoglobulin genes from lamina propria plasma cells, and from virgin IgD+ B cells, was found in patients with ulcerative colitis. These biases were not present in the control groups. CONCLUSIONS: There is a fundamental difference in the immunoglobulin genes from patients with ulcerative colitis. Whether this is caused by a difference in content of immunoglobulin gene segments in the germline or a difference in the recombination mechanism is not known. (+info)

Antigen-stimulated dissociation of BCR mIg from Ig-alpha/Ig-beta: implications for receptor desensitization. (2/605)

B cell antigen receptor (BCR) ligation leads to receptor desensitization wherein BCR remain competent to bind antigen and yet fail to transduce signals. Desensitized BCR exhibit a defect at the most proximal level of signal transduction, consistent with failed transmission of signals through the receptor complex. We report that antigen stimulation leads to dissociation or destabilization of the BCR reflected by inability to coimmunoprecipitate Ig-alpha/Ig-beta with mIg. This destabilization is temporally correlated with desensitization and occurs in BCR containing mIgM and mIgD. Induction of BCR destabilization requires tyrosine kinase activation but is not induced by phosphatase inhibitors. BCR destabilization occurs at the cell surface and "dissociated" Ig-alpha/Ig-beta complexes remain responsive to anti-Ig-beta stimulation, suggesting that mIg-transducer uncoupling may mediate receptor desensitization.

IL-5 induces IgG1 isotype switch recombination in mouse CD38-activated sIgD-positive B lymphocytes. (3/605)

Mouse B cells express CD38, whose ligation by anti-CD38 Ab induces their proliferation and protection from apoptosis. We previously showed that stimulation of mouse splenic B cells with IL-5 together with CS/2, an anti-mouse CD38 mAb, induces production of IgG1 and IgM. Here we examined the role of IL-5 and CS/2 in the expression of germline gamma1 transcripts and the generation of reciprocal products forming DNA circles as byproducts of mu-gamma1 switch recombination. By itself, CS/2 induced significant expression of germline gamma1 transcripts in splenic naive B cells, whereas IL-5 neither induced nor enhanced germline gamma1 expression. Increased cellular content of reciprocal product, which is characteristic of mu-gamma1 recombination, was not observed after culturing B cells with CS/2, but increased reciprocal product, along with high levels of lgG1 secretion, was found when B cells were cultured with CS/2 plus IL-5. Although IL-4 did not, by itself, induce mu-gamma1 recombination in B cells stimulated with CS/2, in conjunction with CS/2 plus IL-5, IL-4 dramatically enhanced sterile gamma1 transcription and IgG1 production. These results demonstrate that CD38 ligation induces only germline gamma1 transcription and that IL-5 promotes both mu-gamma1 switch recombination and lgG1 secretion in an IL-4-independent manner.

Induction of Ig somatic hypermutation and class switching in a human monoclonal IgM+ IgD+ B cell line in vitro: definition of the requirements and modalities of hypermutation. (4/605)

Partly because of the lack of a suitable in vitro model, the trigger(s) and the mechanism(s) of somatic hypermutation in Ig genes are largely unknown. We have analyzed the hypermutation potential of human CL-01 lymphocytes, our monoclonal model of germinal center B cell differentiation. These cells are surface IgM+ IgD+ and, in the absence of T cells, switch to IgG, IgA, and IgE in response to CD40:CD40 ligand engagement and exposure to appropriate cytokines. We show here that CL-01 cells can be induced to effectively mutate the expressed VHDJH-C mu, VHDJH-C delta, VHDJH-C gamma, VHDJH-C alpha, VHDJH-C epsilon, and V lambda J lambda-C lambda transcripts before and after Ig class switching in a stepwise fashion. In these cells, induction of somatic mutations required cross-linking of the surface receptor for Ag and T cell contact through CD40:CD40 ligand and CD80: CD28 coengagement. The induced mutations showed intrinsic features of Ig V(D)J hypermutation in that they comprised 110 base substitutions (97 in the heavy chain and 13 in the lambda-chain) and only 2 deletions and targeted V(D)J, virtually sparing CH and C lambda. These mutations were more abundant in secondary VHDJH-C gamma than primary VHDJH-C mu transcripts and in V(D)J-C than V lambda J lambda-C lambda transcripts. These mutations were also associated with coding DNA strand polarity and showed an overall rate of 2.42 x 10(-4) base changes/cell division in VHDJH-CH transcripts. Transitions were favored over transversions, and G nucleotides were preferentially targeted, mainly in the context of AG dinucleotides. Thus, in CL-01 cells, Ig somatic hypermutation is readily inducible by stimuli different from those required for class switching and displays discrete base substitution modalities. (+info)

The evolutionarily conserved sequence upstream of the human Ig heavy chain S gamma 3 region is an inducible promoter: synergistic activation by CD40 ligand and IL-4 via cooperative NF-kappa B and STAT-6 binding sites. (5/605)

Germline C gamma gene transcription is a crucial event in the process that leads to switch DNA recombination to IgG, but its regulation in the human is poorly understood. We took advantage of our monoclonal model of germinal center B cell differentiation, IgM+ IgD+ CL-01 cells, to define the role of the I gamma 3 evolutionarily conserved sequence (ECS) in the germline transcriptional activation of the human C gamma 3 gene. The I gamma 3 ECS lies upstream of the major I gamma 3 transcription initiation site and displays more than 90% identity with the corresponding human I gamma 1, I gamma 2, and I gamma 4 regions. Reporter luciferase gene vectors containing the human gamma 3 ECS were used to transfect CL-01 cells, which have been shown to undergo Smu-->S gamma 3 DNA recombination, upon engagement of CD40 by CD40 ligand (CD40L) and exposure to IL-4. In these transfected CL-01 cells, CD40:CD40L engagement and exposure to IL-4 synergistically induced gamma 3 ECS-dependent luciferase reporter gene activation. Targeted mutational analysis demonstrated that a tandem NF-kappa B/Rel binding motif is critical for the gamma 3 ECS responsiveness to both CD40L and IL-4, while a STAT-6-binding site is additionally required for IL-4 inducibility. Electrophoretic mobility shift assays showed that p50/p65/c-Rel and STAT-6 are effectively induced by CD40L and IL-4, respectively, and bind to specific DNA motifs within the ECS. These partially overlapping CD40L and IL-4 responsive elements are functionally cooperative as the disruption of one of them prevents synergistic promoter activation. Thus, the gamma 3 ECS is an inducible promoter containing cis elements that critically mediate CD40L and IL-4-triggered transcriptional activation of the human C gamma 3 gene. (+info)

Differential regulation of transcription termination occurring at two different sites on the micro-delta gene complex. (6/605)

The progression of polymerases across the micro-delta Ig heavy chain gene complex is characterized by two termination events occurring at different sites on the transcription unit and at different times during B cell differentiation. We have utilized two mouse strains to analyze the regulatory determinants for these events in primary B cells. In the transgenic pmicro.microdeltaRatt strain a 1160 bp intervening DNA segment (the att site) has been inverted. This mutation results in the abrogation of transcription termination that occurs in early B cells. Using a novel method that takes advantage of an internal ribosome entry site we have further restricted the size of the segment that is needed for inducing transcription termination in transfectants. This 200 bp termination-inducing sequence operates in tumor equivalents of early but not mature B cells and the activity is correlated with differential binding of nuclear proteins. To explore the regulatory basis for the change in site of transcription termination upon B cell activation we have examined the microS-/- deletion mutant strain in which the microS poly(A) site has been eliminated. The results suggest that polyadenylation at the microS site plays a dominant but not exclusive role in regulating transcription termination in activated B cells. (+info)

Serum hyaluronan in patients with multiple myeloma: correlation with survival and Ig concentration. (7/605)

Serum from 386 myeloma patients were analyzed for serum hyaluronan (HYA) at diagnosis. Median age was 68 years (range, 32 to 87 years). The distribution of Ig classes was typical (58% IgG, 21% IgA, 1% IgD, and 20% light chain disease). The patients comprised 58% in stage III, 33% in stage II, and 9% in stage I. The majority (82%) had HYA values within an intermediate range (10 to 120 micrograms/L), 13% had high values (>120 micrograms/L), and 5% had abnormally low values (0 to 9 micrograms/L). For the first time, a patient group with abnormally low HYA serum values is reported. An inverse correlation between survival and HYA serum level was found (P =.015). When tested separately, patients with abnormally low or high HYA values had significantly shorter median survival (21.1 and 19.7 months, respectively) than those with an intermediate HYA concentration (32. 6 months; P =.005). Patients with abnormally low or high HYA levels had more advanced disease as judged by staging and biochemical markers. Interestingly, there was an inverse correlation between the HYA value and the M-component concentration in serum. Fifty percent of patients with abnormally low HYA values had IgA myelomas. In conclusion, the serum concentration of HYA may be of prognostic value in selected cases of multiple myeloma. Further studies will be performed to elucidate possible explanations for our findings, especially those related to the HYA cell surface binding proteins. (+info)

Composite low grade B-cell lymphomas with two immunophenotypically distinct cell populations are true biclonal lymphomas. A molecular analysis using laser capture microdissection. (8/605)

Low grade B-cell lymphomas comprise several well defined, clinically and immunophenotypically distinct disease entities. Composite lymphomas showing phenotypic characteristics of more than one of these tumor subtypes in the same site are rare, and both common and separate clonal origins of the two tumor parts have been reported for cases studied by molecular methods. We describe the detailed immunohistochemical and molecular findings in three cases with features of composite low grade B-cell non-Hodgkin's lymphoma (B-NHL). All three neoplasms contained morphologically distinct but interwoven compartments of different cell types, which exhibited discordant expression of several markers, including CD5, CD10, CD43, and cyclin D1. According to their morphology and phenotypes, they were classified as mantle cell lymphoma and follicular lymphoma (Case 1), follicular lymphoma and small lymphocytic lymphoma (Case 2), and mantle cell lymphoma and chronic lymphocytic leukemia/small lymphocytic lymphoma (Case 3). PCR analysis of DNA obtained from whole tissue sections failed to reveal evidence for biclonality in any of the cases. We therefore isolated cell populations with different antigen expression patterns by laser capture microdissection and analyzed them by polymerase chain reaction amplification and sequencing of clonal immunoglobulin heavy chain gene rearrangements and oncogene rearrangements. Sequence analysis revealed unrelated clonal rearrangements in each of the two tumor parts in all three cases, suggesting distinct clonal origins. In addition, Case 1 showed a bcl-2 rearrangement present only in the follicular lymphoma part. Our findings suggest that low grade B-NHL with two distinct morphological and immunophenotypic patterns in the same anatomical site are frequently biclonal. This is in keeping with current classification schemes, which recognize subtypes of low grade B-NHL as separate disease entities. Furthermore, our analysis demonstrates the power of laser capture microdissection in revealing molecular microheterogeneity in complex neoplasms. (+info)

Immunoglobulin D (IgD) is a type of antibody that is present in the blood and other bodily fluids. It is one of the five classes of immunoglobulins (IgA, IgD, IgE, IgG, and IgM) found in humans and plays a role in the immune response.

IgD is produced by B cells, a type of white blood cell that is responsible for producing antibodies. It is primarily found on the surface of mature B cells, where it functions as a receptor for antigens (foreign substances that trigger an immune response). When an antigen binds to IgD on the surface of a B cell, it activates the B cell and stimulates it to produce and secrete antibodies specific to that antigen.

IgD is found in relatively low concentrations in the blood compared to other immunoglobulins, and its precise functions are not fully understood. However, it is thought to play a role in the regulation of B cell activation and the immune response. Additionally, some research suggests that IgD may have a direct role in protecting against certain types of infections.

It's worth noting that genetic deficiencies in IgD are not typically associated with any significant immunological abnormalities or increased susceptibility to infection.

Immunoglobulin delta-chains (IgD) are a type of heavy chain found in immunoglobulins, which are also known as antibodies. Antibodies are proteins that play a crucial role in the immune system's response to foreign substances, such as bacteria and viruses.

The heavy chains of an antibody consist of four polypeptide regions: the variable region, which varies between different antibodies and is responsible for recognizing and binding to specific antigens; and three constant regions, known as Cμ, Cγ, Cα, or Cδ, which determine the class of the antibody and its effector functions.

IgD heavy chains contain a single Cδ region and are found only in a small subset of antibodies, primarily located on the surface of mature B cells. IgD is co-expressed with IgM on the surface of naive B cells and plays a role in activating the immune response by binding to antigens and initiating signal transduction pathways that lead to B cell activation and differentiation into antibody-secreting plasma cells.

While the function of IgD is not fully understood, it is thought to play a role in regulating the immune response, including modulating allergic reactions and protecting against autoimmunity. Additionally, IgD has been found to have a role in the development and survival of B cells, as well as in the regulation of calcium signaling in B cells.

Mevalonate kinase deficiency (MKD) is a rare autosomal recessive genetic disorder that affects the metabolism of cholesterol and other essential isoprenoids. It is caused by mutations in the MVK gene, which provides instructions for making the enzyme mevalonate kinase.

This enzyme plays a critical role in the production of isoprenoids, including cholesterol, coenzyme Q10, and dolichols, which are essential for various cellular functions such as membrane stability, protein prenylation, and glycosylation. In MKD, the deficiency of mevalonate kinase leads to an accumulation of its substrate, mevalonic acid, and a decrease in isoprenoid production.

MKD has two clinical manifestations: hyperimmunoglobulin D syndrome (HIDS) and mevalonic aciduria (MA). HIDS is the milder form of the disorder, characterized by recurrent fever episodes, gastrointestinal symptoms, rash, lymphadenopathy, and joint pain. MA is the severe form of MKD, which presents with developmental delay, neurological impairment, cataracts, failure to thrive, and recurrent infections. Both forms of MKD are associated with increased levels of mevalonic acid in body fluids, including urine and blood.

The diagnosis of MKD is based on clinical features, biochemical markers, and genetic testing. Treatment options for MKD include anti-inflammatory medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and biologic agents such as anakinra and canakinumab, which target the interleukin-1 (IL-1) pathway. In some cases, dietary modifications and supplementation with coenzyme Q10 may also be beneficial.

Immunoglobulin constant regions are the invariant portions of antibody molecules (immunoglobulins) that are identical in all antibodies of the same isotype. These regions are responsible for effector functions such as complement activation, binding to Fc receptors, and initiating immune responses. They are composed of amino acid sequences that remain unchanged during antigen-driven somatic hypermutation, allowing them to interact with various components of the immune system. The constant regions are found in the heavy chains (CH) and light chains (CL) of an immunoglobulin molecule. In contrast, the variable regions are responsible for recognizing and binding to specific antigens.

Immunoglobulin M (IgM) is a type of antibody that is primarily found in the blood and lymph fluid. It is the first antibody to be produced in response to an initial exposure to an antigen, making it an important part of the body's primary immune response. IgM antibodies are large molecules that are composed of five basic units, giving them a pentameric structure. They are primarily found on the surface of B cells as membrane-bound immunoglobulins (mlgM), where they function as receptors for antigens. Once an mlgM receptor binds to an antigen, it triggers the activation and differentiation of the B cell into a plasma cell that produces and secretes large amounts of soluble IgM antibodies.

IgM antibodies are particularly effective at agglutination (clumping) and complement activation, which makes them important in the early stages of an immune response to help clear pathogens from the bloodstream. However, they are not as stable or long-lived as other types of antibodies, such as IgG, and their levels tend to decline after the initial immune response has occurred.

In summary, Immunoglobulin M (IgM) is a type of antibody that plays a crucial role in the primary immune response to antigens by agglutination and complement activation. It is primarily found in the blood and lymph fluid, and it is produced by B cells after they are activated by an antigen.

Immunoglobulin heavy chains are proteins that make up the framework of antibodies, which are Y-shaped immune proteins. These heavy chains, along with light chains, form the antigen-binding sites of an antibody, which recognize and bind to specific foreign substances (antigens) in order to neutralize or remove them from the body.

The heavy chain is composed of a variable region, which contains the antigen-binding site, and constant regions that determine the class and function of the antibody. There are five classes of immunoglobulins (IgA, IgD, IgE, IgG, and IgM) that differ in their heavy chain constant regions and therefore have different functions in the immune response.

Immunoglobulin heavy chains are synthesized by B cells, a type of white blood cell involved in the adaptive immune response. The genetic rearrangement of immunoglobulin heavy chain genes during B cell development results in the production of a vast array of different antibodies with unique antigen-binding sites, allowing for the recognition and elimination of a wide variety of pathogens.

Immunoglobulins (Igs), also known as antibodies, are glycoprotein molecules produced by the immune system's B cells in response to the presence of foreign substances, such as bacteria, viruses, and toxins. These Y-shaped proteins play a crucial role in identifying and neutralizing pathogens and other antigens, thereby protecting the body against infection and disease.

Immunoglobulins are composed of four polypeptide chains: two identical heavy chains and two identical light chains, held together by disulfide bonds. The variable regions of these chains form the antigen-binding sites, which recognize and bind to specific epitopes on antigens. Based on their heavy chain type, immunoglobulins are classified into five main isotypes or classes: IgA, IgD, IgE, IgG, and IgM. Each class has distinct functions in the immune response, such as providing protection in different body fluids and tissues, mediating hypersensitivity reactions, and aiding in the development of immunological memory.

In medical settings, immunoglobulins can be administered therapeutically to provide passive immunity against certain diseases or to treat immune deficiencies, autoimmune disorders, and other conditions that may benefit from immunomodulation.

B-lymphocytes, also known as B-cells, are a type of white blood cell that plays a key role in the immune system's response to infection. They are responsible for producing antibodies, which are proteins that help to neutralize or destroy pathogens such as bacteria and viruses.

When a B-lymphocyte encounters a pathogen, it becomes activated and begins to divide and differentiate into plasma cells, which produce and secrete large amounts of antibodies specific to the antigens on the surface of the pathogen. These antibodies bind to the pathogen, marking it for destruction by other immune cells such as neutrophils and macrophages.

B-lymphocytes also have a role in presenting antigens to T-lymphocytes, another type of white blood cell involved in the immune response. This helps to stimulate the activation and proliferation of T-lymphocytes, which can then go on to destroy infected cells or help to coordinate the overall immune response.

Overall, B-lymphocytes are an essential part of the adaptive immune system, providing long-lasting immunity to previously encountered pathogens and helping to protect against future infections.

Immunoglobulin G (IgG) is a type of antibody, which is a protective protein produced by the immune system in response to foreign substances like bacteria or viruses. IgG is the most abundant type of antibody in human blood, making up about 75-80% of all antibodies. It is found in all body fluids and plays a crucial role in fighting infections caused by bacteria, viruses, and toxins.

IgG has several important functions:

1. Neutralization: IgG can bind to the surface of bacteria or viruses, preventing them from attaching to and infecting human cells.
2. Opsonization: IgG coats the surface of pathogens, making them more recognizable and easier for immune cells like neutrophils and macrophages to phagocytose (engulf and destroy) them.
3. Complement activation: IgG can activate the complement system, a group of proteins that work together to help eliminate pathogens from the body. Activation of the complement system leads to the formation of the membrane attack complex, which creates holes in the cell membranes of bacteria, leading to their lysis (destruction).
4. Antibody-dependent cellular cytotoxicity (ADCC): IgG can bind to immune cells like natural killer (NK) cells and trigger them to release substances that cause target cells (such as virus-infected or cancerous cells) to undergo apoptosis (programmed cell death).
5. Immune complex formation: IgG can form immune complexes with antigens, which can then be removed from the body through various mechanisms, such as phagocytosis by immune cells or excretion in urine.

IgG is a critical component of adaptive immunity and provides long-lasting protection against reinfection with many pathogens. It has four subclasses (IgG1, IgG2, IgG3, and IgG4) that differ in their structure, function, and distribution in the body.

Immunoglobulin A (IgA) is a type of antibody that plays a crucial role in the immune function of the human body. It is primarily found in external secretions, such as saliva, tears, breast milk, and sweat, as well as in mucous membranes lining the respiratory and gastrointestinal tracts. IgA exists in two forms: a monomeric form found in serum and a polymeric form found in secretions.

The primary function of IgA is to provide immune protection at mucosal surfaces, which are exposed to various environmental antigens, such as bacteria, viruses, parasites, and allergens. By doing so, it helps prevent the entry and colonization of pathogens into the body, reducing the risk of infections and inflammation.

IgA functions by binding to antigens present on the surface of pathogens or allergens, forming immune complexes that can neutralize their activity. These complexes are then transported across the epithelial cells lining mucosal surfaces and released into the lumen, where they prevent the adherence and invasion of pathogens.

In summary, Immunoglobulin A (IgA) is a vital antibody that provides immune defense at mucosal surfaces by neutralizing and preventing the entry of harmful antigens into the body.

Intravenous Immunoglobulins (IVIG) are a preparation of antibodies, specifically immunoglobulins, that are derived from the plasma of healthy donors. They are administered intravenously to provide passive immunity and help boost the immune system's response in individuals with weakened or compromised immune systems. IVIG can be used for various medical conditions such as primary immunodeficiency disorders, secondary immunodeficiencies, autoimmune diseases, and some infectious diseases. The administration of IVIG can help prevent infections, reduce the severity and frequency of infections, and manage the symptoms of certain autoimmune disorders. It is important to note that while IVIG provides temporary immunity, it does not replace a person's own immune system.

Immunoglobulins (Igs), also known as antibodies, are proteins produced by the immune system to recognize and neutralize foreign substances such as pathogens or toxins. They are composed of four polypeptide chains: two heavy chains and two light chains, which are held together by disulfide bonds. The variable regions of the heavy and light chains contain loops that form the antigen-binding site, allowing each Ig molecule to recognize a specific epitope (antigenic determinant) on an antigen.

Genes encoding immunoglobulins are located on chromosome 14 (light chain genes) and chromosomes 22 and 2 (heavy chain genes). The diversity of the immune system is generated through a process called V(D)J recombination, where variable (V), diversity (D), and joining (J) gene segments are randomly selected and assembled to form the variable regions of the heavy and light chains. This results in an enormous number of possible combinations, allowing the immune system to recognize and respond to a vast array of potential threats.

There are five classes of immunoglobulins: IgA, IgD, IgE, IgG, and IgM, each with distinct functions and structures. For example, IgG is the most abundant class in serum and provides long-term protection against pathogens, while IgA is found on mucosal surfaces and helps prevent the entry of pathogens into the body.

Immunoglobulin light chains are the smaller protein subunits of an immunoglobulin, also known as an antibody. They are composed of two polypeptide chains, called kappa (κ) and lambda (λ), which are produced by B cells during the immune response. Each immunoglobulin molecule contains either two kappa or two lambda light chains, in association with two heavy chains.

Light chains play a crucial role in the antigen-binding site of an antibody, where they contribute to the specificity and affinity of the interaction between the antibody and its target antigen. In addition to their role in immune function, abnormal production or accumulation of light chains can lead to various diseases, such as multiple myeloma and amyloidosis.

Immunoglobulin kappa-chains are one of the two types of light chains (the other being lambda-chains) that make up an immunoglobulin molecule, also known as an antibody. These light chains combine with heavy chains to form the antigen-binding site of an antibody, which is responsible for recognizing and binding to specific antigens or foreign substances in the body.

Kappa-chains contain a variable region that differs between different antibodies and contributes to the diversity of the immune system's response to various antigens. They also have a constant region, which is consistent across all kappa-chains. Approximately 60% of all human antibodies contain kappa-chains, while the remaining 40% contain lambda-chains. The relative proportions of kappa and lambda chains can be used in diagnostic tests to identify clonal expansions of B cells, which may indicate a malignancy such as multiple myeloma or lymphoma.
