The Major Histocompatibility Complex of Old World Camels-A Synopsis.

This study brings new information on major histocompatibility complex (MHC) class III sub-region genes in Old World camels and integrates current knowledge of the MHC region into a comprehensive overview for Old World camels. Out of the MHC class III genes characterized, and the LY6 gene family showed high levels of conservation, characteristic for MHC class III loci in general. For comparison, an MHC class II gene , not coding for antigen presenting molecules but functionally related to MHC antigen presenting functions was studied.

The major histocompatibility complex of Old World camelids: Class I and class I-related genes.

The genomic structure of the Major Histocompatibility Complex (MHC) region and variation in selected MHC class I related genes in Old World camels, Camelus bactrianus and Camelus dromedaries were studied. The overall genomic organization of the camel MHC region follows a general pattern observed in other mammalian species and individual MHC loci appear to be well conserved. Selected MHC class I genes B-67 and BL3-7 exhibited unexpectedly low variability, even when compared to other camel MHC class I related genes MR1 and MICA.
