It is a mechanism whereby rearranged thesizing antibody expresses just one of two alleles encoding genes in B lineage cells may undergo secondary rearrange- an immunoglobulin chain at a particular locus. P-addition is the appending of nucleotides from cleaved hairpin loops produced by the junction of V-D or D-J gene Gene rearrangement refers to genetic shuffing that results segments during rearrangements of immunoglobulin or T in elimination of introns and the joining of exons to produce cell receptor genes. Gene rearrangement within a lymphocyte signifes its dedication to the formation of a single cell type, which D gene region is the diversity region of the genome that may be immunoglobulin synthesis by B lymphocytes or pro- encodes heavy-chain sequences in the immunoglobulin H duction of a β-chain receptor by T lymphocytes. The D or diversity region One-turn recombination signal sequences are immuno- governs antibody specifcity and probably T cell receptor globulin gene-recombination signal sequences separated by specifcity as well. This part of the heavy-chain variable lier hypothesis which proposed that one gene encodes one region is frequently signifcant in determining antibody enzyme or other protein. These immunoglubulin heavy chain and T cell receptor β and δ loci N-nucleotides may be present both 3′ and 5′ to the rearranged together with J segments are recombined somatically with V immunoglobulin heavy chain’s D gene segment as well as segments during lymphocyte development. D segments used randomly contribute to antigen N-region diversifcation: In junction diversity, this is the receptor repertoire diversity. It αand β genes and in Ig heavy chain genes but not in Ig light is situated on the 5′ side of J exons. During lymphocyte differentiation, V-D-J sequences are produced that encode the complete variable region of the N-addition: To append nucleotides by TdT during D-J join- heavy chain. They are added to junctions between V, D, and J component expression in B cell development. When as many as 20 of these nucleotides are added, the diversity of the antibody and Combinatorial joining is a mechanism for one exon to unite T cell receptor repertoires is expanded. Immunoglobulin is the product of a mature B cell product synthesized in response to stimulation by an antigen. Antibody Combinatorial diversity refers to the numerous different molecules are immunoglobulins of defned specifcity pro- combinations of variable, diversity, and joining segments duced by plasma cells. It serves as a mechanism for generat- classes based on the antigenic specifcity of the heavy chains. The three major classes A coding joint is a structure formed when a V gene segment are IgG, IgM, and IgA, and the two minor classes are IgD and joins imprecisely to a (D)J gene segment in immunoglobulin IgE, which together comprise less than 1% of the total immu- or T cell receptor genes. The two types of light chains (termed κ and λ) are present in all fve immunoglobulin classes, although only A mutation is a structural change in a gene that leads to one type is present in an individual molecule. The basic monomeric unit is Y may be inherited by future generations, whereas somatic shaped, with a hinge region rich in proline and susceptible cell mutations are inherited only by the progeny of that cell to cleavage by proteolytic enzymes. A point mutation is an have a constant region at the carboxy terminus and a vari- alteration in a single base pair. The two heavy chains are may be expressed as translocation, deletion, inversion, or alike, as are the two light chains in any individual immuno- duplication. Approximately 60% of human immuno- globulin molecules have κ light chains and 40% have λ light Mutant is an adjective that describes a mutation that may chains. The fve immunoglobulin classes are termed isotypes have occurred in a gene, protein, or cell. Two immunoglobulin classes, IgA and IgG, have The N region is a brief segment of an immunoglobulin been further subdivided into subclasses based on H-chain molecule’s or T cell receptor chain’s variable region that differences. The second 3′ coding region is part of an exon that codes for the terminal 4 signal peptide residues and Digestion of IgG molecules with papain yields two 95 to 100 variable region residues. By contrast, the Fc fragment has no in the encoding of immunoglobulin heavy chain and T cell antigen-binding site but is responsible for fxation of com- receptor β and δ chains. Pepsin cleaves the molecule toward the carboxy termi- Membrane immunoglobulin is cell surface immunoglob- nal end of the central disulfde bond, yielding an F(ab’)2 ulin that serves as an antigen receptor. L chains have a single variable and activation by antigen, the B cell differentiates into a plasma constant domain, whereas H chains possess one variable cell that secretes IgM molecules. IgM is a four-polypeptide chain monomer, the secreted IgM is a pentameric molecule containing fve four-chain unit Secretory IgA is found in body secretions such as saliva, monomers and one J chain. IgG and IgA membrane are present as membrane-bound immunoglobulins on B immunoglobulins probably serve as memory B cell antigen cells, where they interact with antigen to activate B cells. That segment of the immunoglobulin introduced IgE is associated with anaphylaxis, and IgG, which is the into the cell membrane is a hydrophobic heavy-chain region only immunoglobulin capable of crossing the placenta, is the in the vicinity of the carboxy terminus. One or only one isotype is expressed at any one time with the excep- more exons may be involved.

Monocytes and macrophages as well as granulo- cytes that participate in infammatory responses have been identifed in fsh. Mast cells have not been demonstrated but a granulocytic cell with eosinophilic granules that otherwise resembles mast cells has been described together with natu- ral cytotoxic cells. Fish demonstrate both humoral and cell- mediated immunity which is temperature dependent. An IgM-like antibody is the only immunoglobulin fsh, the placoderms are now known, such as those from class present. It is a tetrameric molecule, and in some species elasmobranchs, which include sharks and rays; teleost fsh, it is monomeric.
