As shown in Fig. 1A, ADRA1B had mean normalized counts of 212 in asthma-donor-derived HASM cells and 247 in nonasthma-donor-derived HASM cells, values that were approximately 10-fold higher than those of ADRB2, which encodes the β2AR (mean normalized counts of 28 and 17 in asthma- and nonasthma-donor-derived HASM cells, respectively). Here, ADRB2 is linked to asthma.
