Total and differential of inflammatory cells in BALF. The C57Bl/6 mice were treated with Lacticaseibacillus rhamnosus (109 CFU Lr in 300 µL of PBS, orogastric by gavage) for 14 days or one day, before the instillation of E. coli LPS (0.5 mg/Kg, intranasal). The mice were euthanized 24 h after the LPS, and the BALF was processed according to Materials and Methods. Total cells (2A); neutrophils (2B); Macrophages (2C); lymphocytes (2D). The results are expressed as mean ± SEM ****p < 0.0001; ***p < 0.001; **p < 0.01; *p < 0.05 and ns: non-significant difference.
