B lymphocytes switch from secreting IgM to secreting IgG, IgA or IgE through a DNA recombination, class switch recombination (CSR), whose mechanism is incompletely understood. CSR is thought to be triggered by activation-induced deaminase (AID), whic

The 3-megabase Igkappa locus undergoes differentially controlled nuclear positioning events and chromatin structural changes during the course of B cell development. The temporal association of chromatin structural changes, transcription, and recombi

Class switch recombination (CSR) at the DNA level underlies ability of B lymphocytes to switch from expressing IgM to expressing IgG, IgA, or IgE. The mechanism of CSR is largely unknown, but it is clear that CSR is stimulated by T cell signals and i

The human IgH 3′ enhancers, located downstream of each of the two Cα genes, modulate germline (GL) transcription of the IgH genes by influencing the activity of promoter-enhancer complexes upstream of the switch and intervening (I) regions. The re

Cartilaginous fish are the most ancient extant jawed vertebrates possessing bona fide immunoglobulin (Ig) and T-cell receptor molecules. The study of these animals is critical for understanding the origins of the vertebrate immune system. Here, Samue

The rearrangement of antibody and T-cell receptor gene segments is indispensable to the vertebrate immune response. All extant jawed vertebrates can rearrange these gene segments. This ability is conferred by the recombination activating genes I and

We determined the sequence of 18 DNA clones encoding VH regions of sandbar shark and bull shark. All of these sequences exhibit key structural coding features characteristic of known VH genes of higher vertebrates. These VH sequences disclosed consid

Interferon gamma (IFNgamma) is an important cytokine with immunomodulatory properties that include activation of immune cells and induction of class I and class II major histocompatibility complex antigens. In this study a retroviral vector was used

The immune response of jawed vertebrates is an inducible, highly specific defense mechanism that is characterized by an enormous diversity in recognition capacity. This allows responses to potential pathogens that have never been previously encounter
