Biomarkers in schizophrenia: A focus on blood based diagnostics and theranostics

Figure 2 A summation of studies into peripheral biomarkers for schizophrenia. Studies are classified based on A: Blood cell types (e.g., serum/plasma, PBMC, lymphocytes, whole blood cells, leukocyte, plateles or red blood cells); B: Research focus (e.g., proteins, mRNA, enzyme activity assays, DNA methylation, or miRNA). The numbers indicate the number of studies in the categories, and its overall percentage. PBMC: Peripheral blood mononuclear cells; RBC: Red blood cell.
