Nonhuman primates are widely used to study correlates of protective immunity in AIDS research. Successful cellular immune responses have been difficult to identify because heterogeneity within macaque major histocompatibility complex (MHC) genes results in quantitative and qualitative differences in immune responses. Here we use microsatellite analysis to(More)
The rhesus macaque (Macaca mulatta) is an excellent model for human disease and vaccine research. Two populations exhibiting distinctive morphological and physiological characteristics, Indian- and Chinese-origin rhesus macaques, are commonly used in research. Genetic analysis has focused on the Indian macaque population, but the accessibility of these(More)
There are currently no nonhuman primate models with fully defined major histocompatibility complex (MHC) class II genetics. We recently showed that six common MHC haplotypes account for essentially all MHC diversity in cynomolgus macaques (Macaca fascicularis) from the island of Mauritius. In this study, we employ complementary DNA cloning and sequencing to(More)
Cynomolgus macaques (Macaca fascicularis) provide increasingly common models for infectious disease research. Several geographically distinct populations of these macaques from Southeast Asia and the Indian Ocean island of Mauritius are available for pathogenesis studies. Though host genetics may profoundly impact results of such studies, similarities and(More)
Cynomolgus macaques (Macaca fascicularis) are quickly becoming a useful model for infectious disease and transplantation research. Even though cynomolgus macaques from different geographic regions are used for these studies, there has been limited characterization of full-length major histocompatibility complex (MHC) class I immunogenetics of distinct(More)
BACKGROUND Thus far, live attenuated SIV has been the most successful method for vaccinating macaques against pathogenic SIV challenge; however, it is not clear what mechanisms are responsible for this protection. Adoptive transfer studies in mice have been integral to understanding live attenuated vaccine protection in models like Friend virus. Previous(More)
Rhesus macaques (Macaca mulatta) provide well-established models for studying human disease pathogenesis and vaccine development. When challenged with infectious agents, macaques exhibit individual differences in susceptibility. An important determinant of these differences is the complement of major histocompatability complex (MHC) class I sequences(More)
Asymmetric self-renewing division of neural precursors is essential for brain development. Partitioning-defective (Par) proteins promote self-renewal, and their asymmetric distribution provides a mechanism for asymmetric division. Near the end of neural development, most asymmetric division ends and precursors differentiate. This correlates with Par protein(More)
The neural crest (NC) is first induced as an epithelial population of cells at the neural plate border requiring complex signaling between bone morphogenetic protein, Wnt, and fibroblast growth factors to differentiate the neural and NC fate from the epidermis. Remarkably, following induction, these cells undergo an epithelial-to-mesenchymal transition(More)
One of the major challenges in biology is to explain how complex tissues and organs arise from the collective action of individual polarized cells. The best-studied model of this process is the cross talk between individual epithelial cells during their polarization to form the multicellular epithelial lumen during tissue morphogenesis. Multiple mechanisms(More)
