CBLN1 and COVID-19: Other data obtained from plasma lipidomic analysis from three cohorts (i.e., COVID-19 uninfected subjects, infected with mild symptoms, and infected with severe symptoms) demonstrated that Cer subclasses Cer(d18:0/24:1), Cer(d18:1/24:1), and Cer(d18:1/22:0) increased 48-, 40-, and 33-fold, respectively, in infected plasma samples and to 116-, 91-, and 50-fold, respectively, in plasma samples with respiratory distress [66].
