Further analysis identified some fibrosis-related genes, such as MGP (44), ASPN (45, 46), OGN (47, 48), LUM (49, 50), and CTSK (51–54), that exhibited high expression in HLF compared to NLF (Figure 3B), showing that they might play a critical role in LF fibrosis. This evidence concerns the gene OGN and Lassa fever.
