In nearly all comorbid DataSets, the HSPGs CD44 and NRP1 were consistently increased while bradykinin receptors were only increased in the setting of both Small cell and Non-small cell carcinoma (SCLC/NSCLC), Non-specific interstitial pneumonia (NSIP), and Usual interstitial pneumonia/Idiopathic pulmonary fibrosis (UIP/PF, Figure S2). Here, CD44 is linked to pemphigus foliaceus.
