| Research Abstract |
Physiological roles of three novel phospholipases have been analysed by producing knockout animals. The phospholipases are type I platelet-activating factor acetylhydrolase (PAF-AH (I)), type II platelet-activating factor acetylhydrolase (PAF-AH (II)), and phosphatidylserine-specific phospholipase A1 (PS-PLA1). For PAF-AH (I) and PS-PLA1, we have made knock out mice, and for PAF-AH (II), we have made knockout C.elegans, as the organism express mammalian homologue of PAF-AH (II). The phenotype of each animal are shown in table ;
Table : Phenotype of knockout animals
animals phenotype
PAF-AH (I) mice abnormality on sperm formation
PAF-AH (II) c.elegans abnormality in epidermis formation
PS-PLA1 mice abnormality in T cell development
As these phenotype are not expected, novel function for each phospholipase is suggested, which should be solved in further studies.
