As a result, the mTOR level, determined by ELISA assays, in the serum of patients in the asthma attack group (32.35 ± 14.29 pg/mL) was significantly higher than that in the pneumonia (12.34 ± 7.10 pg/mL) and control (8.73 ± 4.76 pg/mL) groups, whereas elevation of mTOR was not observed in patients in asthma remission (13.41 ± 7.09 pg/mL, Fig. 1a). Here, MTOR is linked to pneumonia.
