Witryna22 maj 2012 · Abstract. Background: From humans to frogs, immunoglobulin class switching introduces different effector functions to antibodies through an intrachromosomal DNA recombination process at the heavy-chain locus. Although there are two conventional antibody classes (IgM, IgW) in sharks, their heavy chains are … WitrynaSummary. Class-switch recombination (CSR) is a DNA recombination process that replaces the immunoglobulin (Ig) constant region for the isotype that can best protect against the pathogen.

Isotype switching in … Witryna1 sie 2008 · Thus, it is important to characterize mediators controlling isotype switching, as well as their contribution to the overall B cell response. Isotype switching in human naive B cells can be induced by CD40L together with IL-4, IL-10, IL-13, and/or TGF-beta. Recently, IL-21 was identified as a switch factor for IgG1 and IgG3.

WitrynaAffinity maturation and class switching of antibodies are temporally, but not mechanistically, related processes. The basis of affinity maturation is the selection, in the germinal centers, of antibodies that bind the antigen better. Early in an immune response, the selection is from the primary rep … Witryna23 lip 2012 · The fact that isotype switching can alter the affinity and/or specificity of an Ab implies that primary and secondary responses could originate from different B-cell …

WitrynaImmunoglobulin (Ig) class switch recombination (CSR) is the gene rearrangement process by which B lymphocytes change the Ig heavy chain constant region to permit a switch of Ig isotype from IgM to IgG, IgA, or IgE. At the DNA level, CSR occurs via generation and joining of DNA double strand breaks ( …
