Hyaluronan Signaling during Ozone-Induced Lung Injury Requires TLR4, MyD88, and TIRAP
Figure 7
HA challenge was not sufficient for either neutrophilic inflammation or epithelial injury.
(A) There were no observed differences in cellular inflammation in the airspace 2 hours after direct challenge to HA, (B) When compared to ozone challenge, HA challenge had no observed effect on the level of BALF total protein (*p<0.05, vs. FA exposed group, N = 5).
