Somatic (O) antigen 2 of Salmonella paratyphi A replaced somatic antigen 4 of an S. typhimurium recipient as the consequence of mating with an S. paratyphi A var. durazzo Hfr strain. The genetic determinants of these O antigens behaved in this cross as alleles of a common O locus, which is linked to the determinant of histidine biosynthesis, his. By employing phage lysates obtained by growth of...
Although the antigen expression patterns of childhood acute lymphoblastic leukemia (ALL) are well known, little attention has been given to standardizing the diagnostic and classification criteria. We retrospectively analyzed the flow cytometric data from a large study of antigen expression in 1,774 children with newly diagnosed ALL in JPLSG. T- and B-lineage ALL accounted for 13 and 87% of chi...
This transaction reports on the on-going attempt to isolate anti-peptide scFv antibodies from an scFv phage-display library capable of detecting the native protein from which the peptide sequence was derived. The display of antibody fragments on the surface of filamentous bacteriophage by fusion to the minor coat protein (plll) and selection of phage with antigen, has provided a powerful method...
The entire nucleotide sequence of genomic DNA was determined for hepatitis B virus (HBV) of subtype ayr, which had been derived from the blood of a Japanese asymptomatic carrier. The genome was 3215 nucleotides long, and differed in DNA sequence by 10% from that of subtypes adw or ayw, but by only 2% from that of subtype adr. Amino acid sequences coded for by the S, C, P and X genes, as well as...
Recent years have witnessed much progress in both basic research and clinical trials regarding cancer immunotherapy with chimeric antigen receptor (CAR)-engineered T cells. The unique structure of CAR endows T cell tumor specific cytotoxicity and resistance to immunosuppressive microenvironment in cancers, which helps patients to better tackle the issue of immunological tolerance. Adoptive immu...
