Research Summary

(Written in 2018)
We have been studying the molecular and cellular mechanisms underlying the development of the vertebrate central nervous system. The scope of our interests also encompasses mechanisms for various functions of the mature brain, including sensation, emotion, behavior, learning and memory. The main research themes are as follows.

  1. Brain mechanisms for the blood-pressure control and body-fluid homeostasis
  2. Functional roles of receptor-type protein tyrosine phosphatases (RPTPs)
  3. Mechanisms for the neural projection and synapse formation

Figure 1. Disorganized lamination in the Apc2-deficient brain

A. In the wild-type cortex, FoxP2-positive cells are distributed in the layer IV.  In contrast, in the Apc2-deficient cortex, they are broadly distributed in the upper layers.
B. In the mutant cerebellum, granule cells (indicated by arrowheads) are abnormally distributed in the molecular layer (ML), and the layering of Purkinje cells (arrows) was also affected.
C. In the mutant hippocampus, many pyramidal cells are ectopically distributed (arrowheads).  In addition, dentate granule cells are less densely packed in the mutant (arrows).
The APC2 deficiency  was revealed to be a crucial cause for Sotos syndrome (see Almuriekhi et al., Cell Reports 10, 1585-1598, 2015).
