ADORA2A and congenital rubella syndrome: After behavioral testing, the analysis of A2AR levels in the septum, PFC, hippocampus, striatum and hypothalamus revealed a selective increase (1.58 times of control, p = 0.0003) of A2AR density in the septum without significant changes in the three other brain regions (Supplementary Fig. 6e, f), as previously observed in the CRS model.
