Abstract:
The kappa light chain locus of swine has been mapped to chromosome 3q12-q14 but at this time, there is not enough information comprising the variable region genes or their transcripts. Here we report the sequences of five transcripts of swine kappa light chain variable region obtained from the spleen of two adult Yorkshire pigs. The lengths of the deduced sequences of these transcripts were variable (between 107 to 112 amino acids). Comparisons of the nucleotide sequences of their variable regions with other species like human and murine VL genes shows a high degree of identity, indicating the use of at least two different families of variable light genes. The contribution of these genes to the generation of variability in swine light chain variable genes as well as their therapeutic use in humans is discussed. An interesting possibility would be the development of an antiretroviral vaccine, useful to protect against a potential risk of infections due to xenotransplantation.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
