Strain developmentDeveloped by Yuchio Yanagawa, Gunma University Graduate School of Medicine and Hiromu Yawo, Tohoku University Graduate School of Life Sciences in 2002-2003. Transgene was injected into the introduced into the pronuclei of B6D2F2 fertilized eggs. The Tg mice were crossed to C57BL/6J.
Strain descriptionVesicular exocytosis at presynaptic terminals is fundamental function for neurotransmission and brain function. The lumen of a secretory vesicle is acidic (pH 5.6), whereas it becomes neutral (pH 7.4) instantaneously upon exocytosis. The intravesicular change of pH can be detected by a fluorescence change of a pH-sensitive derivative of green fluorescent protein (pHluorin). SynaptopHluorin (SpH) is a fusion protein of pHluorin and syntaxin (VAMP2) for targeting to secretory vesicles. Thy1-SpH transgenic mouse expresses SpH in brain under the control of neuron-specific Thy1.2 promoter. This strain is useful for studies of presynaptic terminals in various regions of the brain. The spH mRNAs was expressed in whole brains of TV-7, TV-10, and TV-34 transgenic lines, whereas in TV-42, it was expressed in the specific regions of the hippocampus. Tg mice mice show no obvious abnormality.
