| Research Abstract |
In contrast to wild-type mice, numbers of bone marrow cells, spleen cells, and peripheralerythrocytes were slightly but significantly decreased in RP S19 oligomer functionaldeficient (Knock-In) mice. Moreover, a ratio of basophilic erythroblasts in Knock-In micewas also decreased based on the CD71/TER119 expression values in FACS analysis. When arecovering time of erythrocytes is measured in hemagglutinin-induced hemolytic anemiamice, the time was extended by Knock-In mice. Now, we start to examine whether RP S19oligomers are contributed with DBA. After that, we are to propose a maintenance systemof erythrocytes via RP S19 oligomer-dependent erythroblast island formation.
