1 内分泌系 内分泌学Endocrinology

2 重要項目 ホルモンの定義 内分泌と外分泌 ホルモン分泌の制御、負のフィードバック機構 ホルモンの作用 欠乏症・過剰症

3 Oxytocin、vasopressin と social study, autismとの関係
Oxytocin, vasopressin: trust hormone, love hormone

4 メス(母マウス)の行動 Disrupted maternal behaviour CD38: 免疫細胞に発現しているglycoprotein
f Pups placed at 3 corners    Retrieval and crouch a b c CD38+/+ CD38-/- d Latency to retrieve each pup Duration of crouching 3 pups e 10 20 30 40 Time (s) CD38 +/+ -/- -/- -/- +Saline +OT ** 200 400 600 800 * CD38: 免疫細胞に発現しているglycoprotein 中枢での機能はよくわかっていないが、 Oxytocin分泌に必要

5 オスの行動 reduced social memory a b c d e ** ♂ ♀ Investigation time (s) 20
20 40 60 1 2 3 4 5 -/- +/+ +NaCl +OT +AVP +Lenti-GFP +Lenti-hCD38 Repeat for 3 times (total 4 times) 5th time 10 min 1 min No. of trials a b c d 25 50 100 75 (%) +GFP WT e GFP CD38 +/+ -/- -/- -/- -/- hCD38 Lenti ** R140W

6 新発見 These findings shed light on the function of CD38 in the brain and, potentially, in human diseases associated with abnormal social behaviour such as autism.
