Article Title: Dopamine receptor 1 on CaMKII-positive neurons within claustrum mediates adolescent cocaine exposure-induced anxiety-like behaviors and electro-acupuncture therapy

doi: 10.7150/thno.83079

Figure Lengend Snippet: Schematic summary of present study. Adolescent cocaine exposure (ACE) enhances anxiety-like behaviors in male mice during adulthood, accompanied with triggered activation of CaMKII-positive neurons and more dopamine receptor 1 (D1R) on CaMKII-positive neurons (D1R CaMKII ) in claustrum. Either blocking D1R with SCH-23390 or knocking-down D1R CaMKII with virus in the claustrum efficiently reduces claustrum activation, and ultimately suppresses ACE-induced anxiety-like behaviors in mice. By targeting claustrum D1R CaMKII , electro-acupuncture (EA) at acupoints of GV20 and GV29 rescues ACE-increased anxiety-like behaviors in mice during adulthood. In the process, the p-CREB and BDNF may be the potential subsequent signals to D1R CaMKII .
