Analysis of the GSE136831 dataset revealed an elevation in the DC population within IPF patients’ lungs, with significant accumulations specifically in cDC2 (marked by FCGR2B, CLEC10A, FOXN3, ABHD12) and Langerhans cells (indicated by CD1A, FCER1A, CD1E, HLA-DQB2, S100B). Here, CLEC10A is linked to idiopathic pulmonary fibrosis.
