PLOD1 and inflammation: CXCL5 was more strongly expressed in lung epithelial and stromal cells (Figure S4O), consistent with other settings of neutrophilic pulmonary inflammation.41,62 Compared to no-LH mice, the LH mice had a higher CXCL5 message in both lung epithelial cells and lung stromal cells but not lung leukocytes (Figure S4O).
