DNASE1 and inflammatory response: The dosage of B‐NS, PG1, and B‐PM (50 μg per mouse) was adopted based on our preliminary experiments, and the dosage of DNase I (20 IU per mouse) and Dex (1 mg kg−1 body weight) was referred to the previous publications.[38, 39, 40] Compared to the saline‐treated sham group, the cfDNA level increased ≈10 times in bronchoalveolar lavage fluid (BALF) of the OVA‐treated inflammation group, along with an 8‐fold increase in total cells in BALF.
