We tried to reveal the strain specificity of neutralizing mAbs against H3N2 influenza viruses in individuals. A large number of B lymphocytes of a pediatrician were collected by apheresis and two Ab libraries were constructed at 2004 and 2007 by using the phage-display technology. The libraries were screened against 12 different H3 strains of flu isolated between 1968 and 2004. Large numbers of clones...
A DNA replication-related element (DRE)-binding factor (DREF) has been revealed to be an important transcription factor for activating promoters of cell proliferation and differentiation related genes. The amino acid sequences of DREF are conserved in evolutionary separate Drosophila species, Drosophila melanogaster (Dm) and Drosophila virilis (Dv) in three regions. In the present study, evidence...
The structure of a new niacin metabolite in cultured tobacco cells grown in a high concentration of niacin (1 mM) was confirmed to be 1-O-nicotinoyl-β-d-glucopyranose. This glucoside is thought to be one of the detoxification forms of niacin in plants.
