神经系统中的信号转导

每个有机体都需要适应其环境的变化,以确保最佳的增长和生存。在真核生物中,神经系统负责收集和处理关于内部和外部环境变化的信息。在我们的实验室中,我们采取多层方法来研究神经系统如何发展,并允许动物在复杂和不断变化的环境中做出最佳决策。

鉴定“突触发展组”的新组分
与其他细胞产生的突触连接神经元的数量是神经系统中信息转移效果的关键决定因素。参与在神经系统发育过程中突触生长和连通性的调节的各种蛋白质构成了“突触型新生”。在我们的实验室中,我们使用一系列遗传,细胞生物学和电生理学方法来识别果蝇中突触肌淋的新组分。最终,我们希望改变这些分子的表达和活性将对突触发育的调节产生深远的影响,并且可能对几种神经和精神疾病的治疗意义。

Molecular Mechanisms of Vesicular Trafficking and Function
Vesicles like endosomes and lysosomes play key roles in many biological pathways. In our lab we are taking a reverse-genetic approach to identify new molecules involved in the trafficking and function of these organelles. Our studies are relevant to a variety of human diseases such as cancer, neurodegenerative disease, and lysosomal storage disorders.

成人果蝇的决策神经元网络
电路在神经系统迅速使decisions that are best suited for the survival of the organism. This high-level decision making reflects constant competition between neuronal circuits in the brain. We are using adult Drosophila to investigate the mechanisms of decision making processes at molecular and network levels by studying interactions between different sensory modalities.
