LRP1 and asthma: In the current study, we observed that LRP1 was significantly increased in the tracheal tissues of mice with OVA-induced asthma compared with control mice, as evidenced by both Lrp1 mRNA levels (Figure 1F) and LRP1 β chain protein levels (Figure 1H) being increased, while its expression in the lung tissue of both groups showed no significant difference (Supplemental Figure 1B).
