| Outline of Final Research Achievements |
In recent studies, it has been suggested that Kirrel3 is an autism-associated gene. We generated Kirrel3-knockout (KO) mice and investigated their behavioral phenotypes relevant to autism spectrum disorder (ASD). Kirrel3-KO mice exhibited ASD-like behaviors with hyperactivity. In addition, we observed abnormal synaptic organization in the cerebellum and accessory olfactory bulb in Kirrel3-KO mice. These results suggest that the abnormal synapse formation of cerebellum and accessory olfactory bulb in Kirrel3-KO mice may induce abnormal synaptic activity, which cause ASD-like behaviors with hyperactivity. It remains unknown which neural circuits are impaired in the patients with treatment-resistant autism comorbid with attention deficit hyperactivity disorder (ADHD). Kirrel3-KO mice may be represented a mouse model of ASD comorbid with ADHD and could provide molecular and pathophysiological information for ASD comorbid with ADHD.
