| Research Abstract |
(1) Immuno-hematological comparison between common marmoset and human ; T cell fraction was isolated by MACS beads method using antihuman lymphocyte Ab. The purification efficacy was higher for T cells than B cells using commercially available MoAbs. The isolated T cells, reactive to antihuman CD4 or CD8 Abs, found to be actually stimulated by mitogen.
(2) Analysis of common marmoset multipotent stem cells ; We have cloned cDNAs for marmoset CD34 and c-kit. Nucleotide sequence analysis showed that the former had 89% and the latter had 95% homologies respectively with human counterpart sequences. We have been producing antimarmoset CD34 and c-kit monocloncal Ab to isolate marmoset multipotent hematopoietic stem cells.
(3) Analysis of marmoset major hisocompatibility complex (MHC) ; We have found 7 new alleles in marmoset MHC class II DRB1 alleles using DNA typing method which we developed. Furthermore, we analyzed class I alleles and localized the genes to marmoset chromosome 4.
(4) Production of human disease model ; We have produced marmoset arthritis model after collagen injection. We constructed LacZ and IL-13 adenoviral vectors. The intraarticular injection of the adenovirus suggested the usefulness of IL-13 adenovirus to suppress arthritis in marmosets. We also have been constructing human leukemia in common marmoset using BCR/ABL retrovirus. We have been performing the experiment safely, without producing any replication competent retrovirus.
