 This study examined the serum proteomic profile of patients with thymoma compared to healthy individuals. It found that there were 58 proteins that differed in expression levels between the two groups. These proteins were mainly involved in regulating immune responses and antigen binding, as well as in the complement and coagulation cascades. Additionally, the study identified several proteins that were upregulated in the serum of patients, including those involved in the complement and coagulation cascades.
