The phenomenon of immense variability characteristic of ANTIBODIES. It enables the IMMUNE SYSTEM to react specifically against the essentially unlimited kinds of ANTIGENS it encounters. Antibody diversity is accounted for by three main theories: (1) the Germ Line Theory, which holds that each antibody-producing cell has genes coding for all possible antibody specificities, but expresses only the one stimulated by antigen; (2) the Somatic Mutation Theory, which holds that antibody-producing cells contain only a few genes, which produce antibody diversity by mutation; and (3) the Gene Rearrangement Theory, which holds that antibody diversity is generated by the rearrangement of IMMUNOGLOBULIN VARIABLE REGION gene segments during the differentiation of the ANTIBODY-PRODUCING CELLS.

Gene conversion and hypermutation during diversification of VH sequences in developing splenic germinal centers of immunized rabbits. (1/350)

The young rabbit appendix and the chicken bursa of Fabricius are primary lymphoid organs where the B cell Ab repertoire develops in germinal centers (GCs) mainly by a gene conversion-like process. In human and mouse, V-gene diversification by somatic hypermutation in GCs of secondary lymphoid organs leads to affinity maturation. We asked whether gene conversion, somatic hypermutation, or both occur in rabbit splenic GCs during responses to the hapten DNP. We determined DNA sequences of rearranged heavy and light chain V region gene segments in single cells from developing DNP-specific GCs after immunization with DNP-bovine gamma-globulin and conclude that the changes at the DNA level that may lead to affinity maturation occur by both gene conversion and hypermutation. Selection was suggested by finding some recurrent amino acid replacements that may contribute increased affinity for antigen in the complementarity-determining region sequences of independently evolved clones, and a narrower range of complementarity-determining region 3 lengths at day 15. Some of the alterations of sequence may also lead to new members of the B cell repertoire in adult rabbits comparable with those produced in gut associated lymphoid tissues of young rabbits.  (+info)

Antigen-induced somatic diversification of rabbit IgH genes: gene conversion and point mutation. (2/350)

During T cell-dependent immune responses in mouse and human, Ig genes diversify by somatic hypermutation within germinal centers. Rabbits, in addition to using somatic hypermutation to diversify their IgH genes, use a somatic gene conversion-like mechanism, which involves homologous recombination between upstream VH gene segments and the rearranged VDJ genes. Somatic gene conversion and somatic hypermutation occur in young rabbit gut-associated lymphoid tissue and are thought to diversify a primary Ab repertoire that is otherwise limited by preferential VH gene segment utilization. Because somatic gene conversion is rarely found within Ig genes during immune responses in mouse and human, we investigated whether gene conversion in rabbit also occurs during specific immune responses, in a location other than gut-associated lymphoid tissue. We analyzed clonally related VDJ genes from popliteal lymph node B cells responding to primary, secondary, and tertiary immunization with the hapten FITC coupled to a protein carrier. Clonally related VDJ gene sequences were derived from FITC-specific hybridomas, as well as from Ag-induced germinal centers of the popliteal lymph node. By analyzing the nature of mutations within these clonally related VDJ gene sequences, we found evidence not only of ongoing somatic hypermutation, but also of ongoing somatic gene conversion. Thus in rabbit, both somatic gene conversion and somatic hypermutation occur during the course of an immune response.  (+info)

Secondary rearrangements and hypermutation generate sufficient B cell diversity to mount protective antiviral immunoglobulin responses. (3/350)

Variable (V) region gene replacement was recently implicated in B cell repertoire diversification, but the contribution of this mechanism to antibody responses is still unknown. To investigate the role of V gene replacements in the generation of antigen-specific antibodies, we analyzed antiviral immunoglobulin responses of "quasimonoclonal" (QM) mice. The B cells of QM mice are genetically committed to exclusively express the anti-(4-hydroxy-3-nitrophenyl) acetyl specificity. However, approximately 20% of the peripheral B cells of QM mice undergo secondary rearrangements and thereby potentially acquire new specificities. QM mice infected with vesicular stomatitis virus (VSV), lymphocytic choriomeningitis virus, or poliovirus mounted virus-specific neutralizing antibody responses. In general, kinetics of the antiviral immunoglobulin responses were delayed in QM mice; however, titers similar to control animals were eventually produced that were sufficient to protect against VSV-induced lethal disease. VSV neutralizing single-chain Fv fragments isolated from phage display libraries constructed from QM mice showed VH gene replacements and extensive hypermutation. Thus, our data demonstrate that secondary rearrangements and hypermutation can generate sufficient B cell diversity in QM mice to mount protective antiviral antibody responses, suggesting that these mechanisms might also contribute to the diversification of the B cell repertoire of normal mice.  (+info)

Increased junctional diversity in fetal B cells results in a loss of protective anti-phosphorylcholine antibodies in adult mice. (4/350)

Fetal Igs are less diverse than adult Igs, largely because of the lack of N addition in the absence of Tdt. To test whether the absence of Tdt is essential, we generated Tg mice that express Tdt and add N regions in fetal B cells. When challenged as adults with PC-containing Streptococcus pneumoniae, these mice fail to make the hallmark T15 anti-PC Ab encoded by canonical rearrangements of Ig H and L chain genes. The anti-PC Abs from these mice are altered by premature N addition and do not protect against death from virulent pneumococcal infection. These results show that maintenance of lower Ig diversity in early life is essential for the acquisition of a complete functional adult repertoire.  (+info)

Functional diversity of natural IgM. (5/350)

This paper proposes a method for the quantitative characterization of repertoire diversity of an unknown mixture of antibodies on the basis of its reactivity profile in the quantitative immunoblot (QIB). The QIB is calibrated by measuring the reactivity profiles of supernatants of known 'diversity' (i.e. known numbers of B cell clones). We define a quantitative 'index of variability' (IV) which decreases regularly as the diversity increases and the profiles tend towards a common 'convergence profile'. The calibration procedure is consolidated by a mathematical model based on the Poisson distribution; this theoretical model accounts correctly for the observed convergence behavior. On the basis of this calibration curve, it is possible to estimate the diversity of an unknown antibody mixture from a measure of its IV. We conclude that the functional diversity of natural serum IgM in mice can be estimated at approximately 16,000 clones.  (+info)

B cell repertoire diversity and clonal expansion in multiple sclerosis brain lesions. (6/350)

Multiple sclerosis (MS) lesions in the CNS are characterized by disseminated demyelination with perivascular infiltrates of macrophages, T cells, and B cells. To investigate the origin and characteristics of the B cell population found in MS plaque tissue, we performed molecular studies in 10 MS patients and 4 non-MS control samples. Ig transcripts from the perivascular infiltrated brain lesions were analyzed by complementary-determining region 3 spectratyping to ascertain the B cell heavy chain gene rearrangement repertoire expressed in MS brains. Significant rearrangement diversity and deviation from the normal Ig heavy (H) chain repertoire was observed. The cloning and sequencing of RT-PCR products from families VH1 and VH4 showed a correlation with the profiles obtained by spectratyping. Generally, restricted spectratyping patterns concurred with repetition of in-frame complementary-determining region 3 identical sequences. The analysis of heavy chain variable (VH), diversity (D), and joining (JH) gene segments revealed the increased usage of VH1-69, VH4-34, and VH4-39. Similarly, gene segments from families D2, D3, and JH4 were over-represented. The presence of restricted patterns of rearranged Ig mRNA within the plaque lesion suggests that Ab production in the demyelinating plaque is a local phenomenon and supports the idea that in MS an Ag-driven immune response might be responsible for demyelination.  (+info)

Efficient antibody diversification by gene conversion in vivo in the absence of selection for V(D)J-encoded determinants. (7/350)

Antibody diversification in the bursa of Fabricius occurs by gene conversion: pseudogene-derived sequences replace homologous sequences in rearranged immunoglobulin genes. Bursal cells expressing a truncated immunoglobulin mu heavy chain, introduced by retroviral gene transfer, bypass normal requirements for endogenous surface immunoglobulin expression. Immunoglobulin light chain rearrangements in such cells undergo gene conversion under conditions where the products are not selected based on their ability to encode a functional protein. The efficiency with which gene conversion maintains a productive reading frame exceeds 97% under such non-selective conditions. By analysis of donor pseudogene usage we demonstrate that bursal cell development is not driven by a restricted set of antigenic specificities. We further demonstrate that gene conversion can restore a productive reading frame to out-of-frame VJ(L) junctions, providing a rationale for the elimination of cells containing non-productive VJ(L) rearrangements prior to the onset of gene conversion in normal bursal cell development.  (+info)

Antibody repertoires of four- and five-feature translocus mice carrying human immunoglobulin heavy chain and kappa and lambda light chain yeast artificial chromosomes. (8/350)

We have produced mice that carry the human Ig heavy (IgH) and both kappa and lambda light chain transloci in a background in which the endogenous IgH and kappa loci have been inactivated. The B lymphocyte population in these translocus mice is restored to about one-third of normal levels, with preferential (3:1) expression of human lambda over human kappa. Human IgM is found in the serum at levels between 50 and 400 microg/ml and is elevated following immunization. This primary human Ab repertoire is sufficient to yield diverse Ag-specific responses as judged by analysis of mAbs. The use of DH and J segments is similar to that seen in human B cells, with an analogous pattern of N nucleotide insertion. Maturation of the response is accompanied by somatic hypermutation, which is particularly effective in the light chain transloci. These mice therefore allow the production of Ag-specific repertoires of both IgM,kappa and IgM,lambda Abs and should prove useful for the production of human mAbs for clinical use.  (+info)

Generation of Antibody Diversity. The big question:how do you get all those different antibodies? Two other big questions- getting different classes with the same variable regions, and getting secreted and membrane-bound forms of the same class Slideshow 6869117 by amal-herring
Combinatorial association of immunoglobulin gene elements is the most important process in the creation of extreme diversity of antibody molecules. The recombination of germ-line variable gene elements V, D, and J can potentially generate approximately 6000 variable genes of human heavy chains. As joining of these elements is imprecise and is occurring with nucleotide additions or deletions, the created diversity is in fact much higher. The assembled variable genes can be revised and edited resulting in a change of their affinity and even specificity. Due to somatic hypermutation, the affinity of synthesized antibody increases even more. Another variant of combinatorial recombination is joining of complete variable genes with one of the several constant genes and the formation of various immunoglobulin isotypes with different effector functions but with the same antibody specificity. Consequently, these processes not only develop the antibody repertoire but also solve some other problems of the adaptive
One of the major roles that B cells play in an immune response is the production of antibodies, that specifically recognise and bind to proteins on the invading bacteria or virus particles. The binding of specific antibody to its target can prevent viruses from entering cells or aid phagocytes in identifying and destroying the bacteria or viruses.

Sequence analysis revealed that S1 mAbs displayed between 85-95% and 89-97% germline identity for heavy and light chains, respectively (Fig. 2C). Analyses of germline gene usage and V(D)J recombination indicate that they originate from different B cell lineages. The role of somatic hypermutations for the two most potent antibodies, mAb100 and mAb114, were analyzed using variants that were partially or completely reverted to the unmutated common ancestors (UCAs) (Fig. 2D and fig. S4, A and B). The fully reverted mAb100 (UCA/UCA), as well as a variant with a single change from the UCA VL (UCA/gL, A89T), recognized cells expressing GP with 2-4 fold weaker binding compared with the fully matured antibody (Fig. 2Eand fig. S4, A and B). When three HCDR3 mutations (A96V/V103Y/Y114S) were introduced in the reverted germline antibody (gH/UCA), binding was comparable to the fully matured mAb100 (sH/sL) suggesting that three mutations are sufficient to confer the binding observed for the fully matured ...

The analysis of B cell development and diversification in humans is problematic and, to a degree, has been inferred from analyses of other mammalian species. However, nature often provides material that is every bit as informative as that generated by laboratory geneticists. One example is patients with common variable immune deficiencies (CVIDs). Among this heterogeneous group are individuals with mutations in key genes required for the formation of GCs (11), which, as mentioned, are sites of antigen-driven repertoire diversification mediated by V gene SHM (1, 2). GC B cell survival and entry into the memory compartments is selective and depends on the affinity with which their receptors bind antigen (12), with higher affinity cells expanding preferentially. This antigen-mediated selection results in a distribution of mutations in the V gene segments of memory B cells that is significantly different from the distribution that would be predicted if mutations were inserted at random; changes ...
BOSTON - As elite soldiers of the bodys immune response, B cells serve as a vast standing army ready to recognize and destroy invading antigens, including infections and cancer cells. To do so, each new B cell comes equipped with its own highly specialized weapon, a unique antibody protein that selectively binds to specific parts of the antigen. The key to this specialization is the antigen-binding region that tailors each B cell to a particular antigen, determining whether B cells survive boot camp and are selected for maturation and survival, or wash out and die.. Now, using high-throughput sequencing technology and computational and systems biology, investigators from Beth Israel Deaconess Medical Center (BIDMC) have discovered that B cells can be selected for survival independent of their antigen binding regions. Described online this week in the journal Proceedings of the National Academy of Sciences (PNAS), the findings add a surprising new dimension to the understanding of antibody ...

Antibodies are key molecules of the adaptive immune response and are now a major class of biopharmaceuticals. Pairing of heavy and light chains is one of the ways of generating antibody diversity and, while little is known about mechanisms governing V(H)/V(L) pairing, previous studies have suggested that the germline source from which chains are paired is random. By selecting paired antibody protein sequences from human and mouse antibodies from the KabatMan database and mapping them onto their corresponding germline sequences, we find that pairing preferences do exist in the germline, but only for a small proportion of germline gene segments; others are much more promiscuous showing no preferences. The closest equivalent human and mouse gene families were identified and pairing preferences compared. This work may impact on the ability to generate more stable antibodies for use as biopharmaceuticals.

The continuous ileal Peyers patches (IPP) of sheep are regarded as a type of mammalian bursal equivalent where B cells diversify their repertoire in an Ag-independent fashion. Anatomically and developmentally similar IPP occur in swine. Resection of ∼90% of the IPP in piglets at birth did not alter Ig levels in serum and secretions or retard diversification of the Ab repertoire when animals were maintained in isolators and colonized with a defined gut flora. Resection or sham surgery elevated IgG and IgA in serum and in lavage fluid from the gut, lung, and in saliva. No changes in the frequency of IgG-, IgA-, and IgM-containing cells in the spleen and peripheral lymph node were observed. Using an index that quantifies diversification of the VDJ repertoire, no differences were seen in three secondary lymphoid tissues between piglets lacking IPP and colonized controls, whereas both groups displayed ,10-fold greater diversification than did late-term fetal piglets or piglets maintained ...
Kohler and Milstein used novel in vitro techniques to combine the immortality of non-secretary myeloma cells with immune B cells to produce hybridomas-immortalised biological factories capable of producing monoclonal antibodies. By prior immunisation of mice, and subsequent selection of splenic B cells producing desired antibody specificity, designer antibodies had arrived.. By 1987, Tonegawa had defined the genetic principle for the generation of antibody diversity. In the 1970s he solved the paradox of how our limited genetic material is capable of generating almost limitless diversity. On the chromosome where the presumed light chain gene was expected to be located, he found not one single gene, but rather, a series of V (variable) and J (joining) genes. After removal of the intervening segment of DNA, any random combination of these genes allows the generation of many alternative light chains. Subsequent studies showed that equivalent V, J, and D (diversity) genes on the heavy chain ...
RNA spike-in standards are becoming an essential tool to assess errors and bias in sequencing data, the most notable example being the establishment of the External RNA Controls Consortium (ERCC) spike-in mix (36). We translated this concept to Ig-seq by designing a set of synthetic (in vitro transcribed) RNA standards. It is impractical to generate a spike-in mix comprising the full diversity of antibody repertoires at a clonal or V-gene level (,140 V-genes in IGHV repertoire of BALB/c mice). However, fractional sample spike-ins, like the ERCC spike-in mix (92 polyadenlyated transcripts), have proven to be valuable and sufficient for evaluation of errors and bias in sequencing data. We designed our synthetic spike-ins to consist of 16 full-length antibody sequences on the basis of mouse VH regions. Notable spike-in features were the incorporation of 16 unique CDR3 amino acid sequences, seven different V-genes, designed positions for somatic hypermutation, a synthetic segment [for bioinformatic ...

Cisco said it learned about the issue in late November and has worked with the component supplier to fix the faulty part. As a result, currently shipping products are not affected.. For customers with affected products under warranty or covered by service contracts through November 16, 2016, Cisco intends to provide replacement products. It is prioritizing replacements for those who have been operating the affected products the longest, because of the correlation between operation time and component failure.. Cisco insists this isnt a recall; rather its a proactive replacement. The company also said that while the component maker indicated failures will become more likely after 18 months, it expects it will take three years of runtime before its products show a spike in failures.. In its advisory, Cisco specifically declines to identify the supplier that made the faulty part, or other affected vendors. And company declined to do so in response to a request from The Register for further ...

N2 - When monoclonal ANAs and non-ANAs generated from a genetically simplified mouse model of lupus, B6.Sle1, were recently compared, the ANAs exhibited three sequence motifs in their immunoglobulin heavy chains, including increased cationicity in CDR3 (motif A), reduced anionicity in CDR2 (motif B) and increased aspartate at H50 (motif C). The present study was designed to elucidate the extent to which these ANA-associated sequence motifs might be hard-wired into the primary B-cell repertoire in lupus. The immunoglobulin heavy chain sequence of total splenic B-cells, follicular B-cells and marginal zone B-cells from B6.Sle1 congenic mice and ...

Diversification of the antibody repertoire in mammals results from a series of apparently random somatically propagated gene rearrangement and mutational events. Nevertheless, it is well known that the adult repertoire of antibody specificities is acquired in a developmentally programmed fashion. As previously shown, rearrangement of the gene segments encoding the heavy-chain variable regions (VH) of mouse antibodies is also developmentally ordered: the number of VH gene segments rearranged in B lymphocytes of fetal mice is small but increased progressively after birth. In this report, human fetal B-lineage cells were also shown to rearrange a highly restricted set of VH gene segments. In a sample of heavy-chain transcripts from a 130-day human fetus the most frequently expressed human VH element proved to be closely related to the VH element most frequently expressed in murine fetal B-lineage cells. These observations are important in understanding the development of immunocompetence. ...
After receiving my Ph.D. studying the structure and function of eukaryotic genes, I chose to focus my research career in the field of Immunology. During my postdoctoral fellowship with Dr. Malcolm Gefter at MIT, I made important contributions to our understanding of the genetic basis for development of antibody diversity during primary and antigen-driven B cell development. My main research interest since that time has been to elucidate the molecular and cellular basis for immune memory and self tolerance in the B cell compartment. My laboratory has extensive utilized mouse model systems and mouse reversed genetics approaches to address these questions for over 25 years. In recent years, we have concentrated on the role of the germinal center in the antigen receptor diversification and selection events that culminate in the development of the memory B cell compartment. To begin to translate the discoveries we have made in mouse model systems to a better understanding of the development of immune ...
In April 1974 Köhler took up a post-doctoral research fellowship at the Laboratory of Molecular Biology in Cambridge, UK where he began working with César Milstein to develop a laboratory tool that could help them investigate the mechanism that underlies the diversity of antibodies. It was during this work that they devised their hybridoma technique for the production of antibodies. Köhler continued his collaboration on the technique when he returned to Basel Institute of Immunology in April 1974.[1] Köhler remained at the Basel Institute for another nine years, during which time he continued investigating antibody diversity and in the early 1980s began working on the development of transgenic mice as a tool to understand the mechanism that underlies self-tolerance. In 1986 Köhler became director of the Max Planck Institute of Immunobiology where he worked until his death in 1995.[2][3]. ...

Activation-induced deaminase (AID) is expressed only in germinal center B cells. There, it is required for somatic hypermutation, gene conversion and class switch recombination of antibody variable region segments, three processes that diversify antibodies during immune responses. Although AID has homology to RNA-editing enzymes, three recent reports suggest it could initiate the diversification processes by deaminating cytidine residues within the antibody genes themselves.
Lower vertebrate species, including Xenopus laevis, exhibit restricted antibody diversity relative to higher vertebrates. We have analyzed more than 180 VH gene-containing recombinant clones from an unamplified spleen cDNA library by selective sequencing of JH and CH positive clones following iterative hybridization screening with family-specific VH probes, 11 unique families of VH genes, each associated with a unique genomic Southern blot hybridization pattern, are described and compared. Considerable variation in the number of hybridizing components detected by each probe is evident. The nucleotide sequence difference between VH families is as great as, if not more than, that reported in other systems, including representatives of the mammalian, avian, and elasmobranch lineages. Some Xenopus Ig gene families encode alternative amino acids at positions that are otherwise invariant or very rarely substituted in known Igs. Furthermore, variations in complementarity determining region sequences ...

However, we overlooked a mechanism natural has adopted for rapid evolution of proteins: adaptive immunity that generates a huge pool of antibodies.It is well-known that B-cells are capable of producing a large pool of new antibodies upon antigen stimuli, which is a most important protective mechanism for animals. People have been curious about the molecular mechanism of antibody generation. Recent works have revealed that an enzyme: Activation-Induced (Cytidine) Deaminase (AID) serves as an essential protein in three processes for antibody diversity, namely somatic hypermutation (SHM), class switch recombination (CSR) and gene conversion. Briefly speaking, AID converts cytidine to uracil by oxidizing the amino group to carbonyl group, resulting in mismatch of Watson-Crick base pair. Then DNA lesion repair pathways (base excision repair, BER; mismatch repair, MMR)are employed to bring DNA back to normal. In this process, the coding sequence for the hypervariable region of immunoglobulin is ...
Human monoclonal antibodies often display limited thermodynamic and colloidal stabilities. This behavior hinders their production, and places limitations on the development of novel formulation conditions and therapeutic applications. Antibodies are highly diverse molecules, with much of the sequence variation observed within variable domain families and, in particular, their complementarity determining regions. This has complicated the development of comprehensive strategies for the stability engineering of the human antibody repertoire. Here we provide an overview of the field, and discuss recent advances in the development of robust and aggregation resistant antibody therapeutics.
