Specificity and Restriction of T Cells in a System of Complementing Ir Genes

1983

The phenomenon of Ir gene control of immune responsiveness is intimately related to the fact that antigen-specific stimulation of T cells with the Lyt-1 surface phenotype requires the simultaneous recognition of both external antigen and Ia antigen on the surface of antigen-presenting cells. There is increasing evidence indicating that Ia antigens encoded for by the I-A and I-E/C subregions of the H-2 complex represent the products of Ir genes.

Pedigree verification with multiple candidate parents using Pedverif software

2010

Species like sheep and beef cattle are commonly raised in large herds and often on pasture with multiple sires joining the females for unrecorded natural insemination. This leads to offspring with multiple candidate parents and therefore uncertain parentage. Twins or triplets can be from multiple sires as well. Pedigrees from such populations are often problematic and need proper verification. The Pedverif computer program is able to verify normal pedigrees as well as pedigrees with multiple candidate parents.
