An examination of Abelson murine leukemia virus (A-MuL V)-hematopoietic cell interaction in cultures of fetal tissues reveals that A-MuLV can stimulate the formation of two different types of colonies. One type of colony is white and composed of A-MuLV-transformed lymphoid cells that can develop into established cell lines. These cells are indistinguishable(More)
Newly assembled heavy chain-beta 2m heterodimers of class I histocompatibility molecules associate with the endoplasmic reticulum (ER) peptide transporter, TAP, and subsequently dissociate from TAP in parallel with their transport from the ER to the Golgi apparatus. It appears that TAP-associated class I molecules are waiting to bind appropriate peptides(More)
Ly-6E, a glycosyl phosphatidylinositol (GPI)-anchored murine alloantigen that can activate T cells upon antibody cross-linking, has been converted into an integral membrane protein by gene fusion. This fusion product, designated Ly-6EDb, was characterized in transiently transfected COS cells and demonstrated to be an integral cell surface membrane protein.(More)
Mice were bred that simultaneously expressed the mutations nude and x-linked immune deficiency (xid). These doubly deficient animals had less than 10% of normal serum immunoglobulin levels. Their spleen cells did not respond to thymus-independent antigens in vitro nor did they respond to lipopolysaccharide. There was a virtual absence of cells with surface(More)
Qa-2, a cell-surface glycoprotein anchored by phosphatidylinositol (PI), is structurally related to the class I transplantation antigens H-2 K, D, and L, which are integral membrane glycoproteins. The predicted transmembrane segment of Qa-2 differs from those of H-2 K, D, and L by the presence of an aspartate in place of a valine at position 295. A single(More)
Glycosylphosphatidylinositol (GPI) serves as a membrane anchor for a large number of eukaryotic proteins. A genetic approach was used to investigate the biosynthesis of GPI anchor precursors in mammalian cells. T cell hybridoma mutants that cannot synthesize dolichol-phosphate-mannose (Dol-P-Man) also do not express on their surface GPI-anchored proteins(More)
We screened a cDNA library prepared from a BALB.B10 CTL clone that expresses Qa-2 antigen, and isolated four clones derived from Q7b, a Qa region gene of C57BL/10. One of these Q7b cDNAs and the Q7b chromosomal gene were subcloned into expression vectors and transfected into L cells and R1.1 thymoma cells. We found that the chromosomal Q7b gene expresses(More)
BACKGROUND AND OBJECTIVES Laparoscopic surgery has rapidly expanded in surgical practice with well-accepted benefits of minimal incision, less analgesia, better cosmetics, and quick recovery. The surgical technique for kidney transplantation has remained unchanged since the first successful kidney transplant in the 1950s. Over the past decade, there were(More)
