A plausible explanation for many MHC-linked diseases is lacking. Sequencing of the MHC class I region (coding units or full contigs) in several human and nonhuman primate haplotypes allowed an analysis of single nucleotide variations (SNV) across this entire segment. This diversity was not evenly distributed. It was rather concentrated within two gene-rich(More)
Cynomolgus macaques are widely used as a primate model for human diseases associated with an immunological process. Because there are individual differences in immune responsiveness, which are controlled by the polymorphic nature of the major histocompatibility (MHC) locus, it is important to reveal the diversity of MHC in the model animal. In this study,(More)
Despite their high degree of genomic similarity, reminiscent of their relatively recent separation from each other ( approximately 6 million years ago), the molecular basis of traits unique to humans vs. their closest relative, the chimpanzee, is largely unknown. This report describes a large-scale single-contig comparison between human and chimpanzee(More)
We have investigated the function of TIE2/TEK receptor tyrosine kinase in the development of definitive hematopoiesis. In the vitelline artery at 9.5 days postcoitum (d.p.c.), TIE2+ hematopoietic cells aggregated and adhered to TIE2+ endothelial cells. Soluble TIE2-Fc chimeric protein inhibited the development of hematopoiesis and angiogenesis in the(More)
The Major Histocompatibility Complex (Mhc) genomic region of many vertebrates is known to contain at least one highly polymorphic class II gene that is homologous in sequence to one or other of the human Mhc DRB1 class II genes. The diversity of the avian Mhc class II gene sequences have been extensively studied in chickens, quails, and some songbirds, but(More)
At least two polymorphic Alu insertions have been previously identified and characterized within the class I region of the major histocompatibility complex (MHC). We have identified another two new polymorphic Alu insertions, AluyHJ and AluyHF, located near HLA-J and HLA-F, respectively, within the a block of the MHC. Here we report on (1). the haplotypic(More)
Anti-inflammatory, analgesic and anti-pyretic effects of d-2-[4-(3-methyl-2-thienyl)phenyl]propionic acid (M-5011), a new non-steroidal anti-inflammatory drug (NSAID), were compared with those of indomethacin, diclofenac sodium and ketoprofen in rats and guinea pigs. Anti-inflammatory effect of M-5011 on ultraviolet-induced erythema in guinea pigs was 11.7(More)
The AluYb8 sequences are a subfamily of short interspersed Alu retroelements that have been amplified within the human genome during recent evolutionary time and are useful polymorphic markers for studies on the origin of human populations. We have identified a new member of the Yb8 subfamily, AluyHG, located between the HLA-H and -G genes and 88-kb(More)
We present the findings on a 27-year-old male with eosinophilic gastro-enterocolitis accompanied with acute pancreatitis. Acute pancreatitis may be induced by pancreatic duct obstruction caused by marked swelling of the papillary region of the duodenum due to eosinophil infiltration. After prednisolone treatment, clinical manifestations rapidly improved;(More)
