Rat invariant TCR alpha-chains and NKT cells were investigated to clarify whether CD1d-mediated recognition by NKT cells is conserved further in evolution. Rats had multiple-copies of TRAV14 genes, which can be categorized into two types according to the diversity accumulated in the CDR2 region. Rats retained invariant TCR alpha forms with the homogeneous(More)
A novel idea is emergxsing that a large molecular repertoire is common to the nervous and immune systems, which might reflect the existence of novel neuronal functions for immune molecules in the brain. Here, we show that the transmembrane adaptor signaling protein CD3zeta, first described in the immune system, has a previously uncharacterized role in(More)
We previously showed that the cell surface-expressed Mr 70,000 heat shock cognate (hsc70, a constitutively expressed member of the hsp70 family) protein-like molecule (#067 molecule) interacts with rat CD3+, CD4-, CD8-, T-cell receptor (TCR)alphabeta-, natural killer recetor-P1- T cells. This 70hsc-like molecule was also suggested to present cellular(More)
We analyzed the structure and pattern of expression of rat TCR zeta- and eta-chains to investigate if these components function in activation and development of rat T cells. The rat zeta cDNA contained the complete open reading frame coding for a polypeptide of 164 amino acids and the 5' and 3' noncoding sequences. Comparison of the amino acid sequence to(More)
A murine mAb, 7D3, was produced by fusion of spleen cells obtained from mice immunized with a rat thymic epithelial cell line, Tu-D3 and NS/1 myeloma cells. 7D3 antibody reacted with approximately 95% thymocytes, 17% spleen cells, less than 9% of mesenteric lymph node cells and 32% of bone marrow cells of rat origin. 7D3 also reacted with two rat thymic(More)

Here, we show that the transmembrane(More)
CD1 and TL were once thought to be genetic homologues because of their thymus-specific expression. We investigated their equivalents in the rat to clarify whether their structure and pattern of expression are conserved in rodents. Two rat class Ib genes, containing 3' sequences very similar to mouse TL, were identified and designated RT1.P. Neither of them,(More)
Copper (Cu) is an indispensable metal for normal development and function of humans, especially in central nervous system (CNS). However, its redox activity requires accurate Cu transport system. ATP7A, a main Cu(2+) transporting-ATPase, is necessary to efflux Cu across the plasma membrane and synthesize cuproenzymes. Menkes disease (MD) is caused by(More)
