The importance of genetic recombination and post recombination events related to diversity in antibodies
Concept introduction:
Antibodies are the potential receptors that can recognize unique aspects of antigen present on the pathogen. Antibodies are produced by the differentiation of B cells into plasma cells. Based on the physical, chemical, and immunological properties, antibodies are classified into 5 classes namely IgG, IgA, IgM, IgE, and IgA. All the antibodies share a common structural similarity by having 2 light and 2 heavy chains. Each light and heavy chain are further classified into “constant (C) and variable (V) domains”. Disulphide bonds connect one light chain with another heavy chain. Each heavy and light chain is derived from the combination of several gene fragments generated after several events of recombination.

- When a mixture of different IgG antibody proteins are treated with the enzyme papain, each antibody is cleaved into three roughly equal size fragments. From each original antibody, two of the three fragments are identical to each other, and represent the ‘arms’ of the antibody ‘Y’. These fragments are known as Fab fragments. The third fragment is known as the Fc region, because this fragment will crystallize when purified. The reason a mixture of Fc fragments will crystallize is because: It is the only part of the antibody protein that can easily be purified at the high concentrations needed for crystallization. It has no disulfide bonds holding the domains together, as disulfide bonds will inhibit crystallization. It is the only fragment of the antibody that still has disulfide bonds, so it remains intact during the crystallization process. The Fc fragments of IgG are much more water soluble than the Fab fragments. All Fc fragments generated from a mixture of IgG molecules have the…arrow_forwardEntanercept is a pharmaceutical that is composed of a recombinant receptor for human tumor necrosis factor, fused to the Fc portion of the immunoglobulin IgG. How does it work?arrow_forwardA wild-type mouse that is heterozygous for two immunoglobulin heavy chain alleles (IgHa/b) generates the population of B cells shown on the left of the figure below. A mouse strain, also IgHa/b, carries an inactivating mutation in the VpreB gene. In addition to producing fewer mature B cells than the wild-type mice, the VpreB-deficient mice generate B cells as shown on the right. What is the explanation of the difference seen between the wild-type and the VpreB-mutant B cells?arrow_forward
- In a set of experiments, T cells from wild-type (WT) or bm12 mice were mixed in vitro with antigen-presenting cells (APCs), in the presence or absence of the superantigen staphylococcal enterotoxin B (SEB), and T cell proliferation was measured. The data from these experiments are shown in the figure below. What is the explanation for the results in Rows 1–4 of the table?. Why does the T cell response to SEB (Rows 5–8) show a different pattern than the response to bovine insulin? Note: Epitope mapping studies identified amino acid residues 1–14 of the bovine insulin A chain as the peptide recognized by CD4 T cells from wild-type mice.arrow_forwardAn important mechanism for generating diversity in immunoglobulin light chain V-region sequences is based on the fact that the RAG recombinase generates hairpin structures, rather than blunt ends, at the cleavage sites between the recombination signal sequences and the coding sequences. Explain how this mechanism generates diversity at the junctions.arrow_forwardB cells are specialized blood cells that secrete antibodies. Normally, human blood has millions of differenttypes of B cells making millions of different kinds ofantibody molecules. This variety occurs because, as described in the Fast Forward Box in Chapter 13 entitledProgrammed DNA Rearrangements and the ImmuneSystem, antibody genes undergo rearrangements in theprecursors of B cells. Individual B cell precursorsrearrange their antibody genes in different ways.In the blood of patients with cancers called B celllymphomas, almost all of the antibody molecules areall of one type, but this single type of antibody isdifferent in different lymphoma patients.a. Based on this information, provide a brief description of the genesis of B cell lymphomas, focusingon the cells that are overproliferating.arrow_forward
- Variable addition and subtraction of nucleotides at the junctions between gene segments contributes to the diversity of [Qi] the third hypervariable region. The addition and subtraction of nucleotides at the junctions between V, D, and J gene segments creates antibody proteins with wide variations in the numbers of amino acids in their CDR3 regions. This variability in CDR3 length is important as: Overall variability in CDR3 sequence is needed to create a sufficiently diverse antibody repertoire. The CDR3 region is more important in binding antigen than the CDR1 and CDR2 regions are. Some light chains bind better to heavy chains with longer CDR3 region sequences. Longer CDR3 sequences generally create antibodies with higher affinity for the antigen. Some antibodies bind relatively flat surfaces and others bind deep clefts in the antigen.arrow_forwardEach immunoglobulin (Ig) domain is composed of a structure known as a ‘b-sandwich,’ which consists of two b sheets covalently linked by a disulfide bond. Only a subset of the ~110 amino acids in each domain are required to establish this overall structure, and it is these amino acids that are highly conserved when comparing Ig domains to each other. What might be the advantage of this structure for use as antibody variable domains?arrow_forwardAntibodies that bind with high affinity to some viral surface proteins require heavy chain CDR3 loops of unusual length. Whereas the average human heavy chain CDR3 length is ~15 amino acids, antibodies with VH CDR3 loops of >30 amino acids are readily detected in the repertoire. These antibody heavy chains with CDR3 lengths of >30 amino acids would likely be missing in individuals lacking: RAG-1 and RAG-2 DNA-dependent protein kinase (DNA-PK) The nuclease, Artemis The Ku70:Ku80 complex Terminal deoxy nucleotidyl transferase (TdT)arrow_forward
- Can you please help me by drawing a serie of schematic figures that demonstrates the information in the paragraph below. The carboxy terminus of the p53 protein acts as an allosteric regulator of sequence-specific DNA binding. This was demonstrated initially by Hupp et al. (1992) using a bacterially expressed protein. Recombinant bacterial p53 bound poorly to DNA, and binding could be enhanced by the addition of antibodies specific to the C-terminal region of the protein. Phosphorylation of Ser315 and Ser392 within this domain also enhance sequence-specific DNA binding. Dephosphorylation of Ser376 of p53 after IR allows the association of 14-3-3 proteins with the C terminus of the protein (Waterman et al., 1998). Stavridi et al. (2001) demonstrate that this interaction is required for p53 to activate the downstream gene, p21waf1/cip1, and for the G1 cell cycle checkpoint arrest response. Interestingly, this dephosphorylation event seems to be ATM-dependent, possibly by a phosphatase…arrow_forwardAlthough mutations have been observed in many different genes, they have not been isolated in histones. Why does this seem reasonable? If one wanted to produce antibodies to histones, would it be an easy task? Explain your answer.arrow_forwardThe p53 protein was discovered through its association with SV40 T antigen and assumed initially to be an oncoprotein. a. What is the current consensus as the function of p53 and what evidence caused this change in view? b. How does the effect of mutation in the p53 gene differ from the effect of mutation in the RB gene what is the molecular basis for this difference ?arrow_forward
