Immunoglobulin allotypes in Hungarian Gypsies. Relationship to populations from India
Abstract:
The allotypic markers of immunoglobulin heavy chains (Gm, Am and Em allotypes) provide important contributions to the differentiation between populations, and they are informative for tracing racial origin, migration and admixture of isolates and stray groups. The combined G1m; G2m; G3m; A2m; Em haplotypes are a highly polymorphic system that is a powerful tool in population genetics because of the existence of haplotypes that are unique for a particular race. In this paper, data on Gypsies living in Hungary are compared with those obtained in other populations, in particular Hindus and non-Hindus from India. The analysis agrees with anthropological and philological evidence for population movements from Asia to Europe.

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.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
