Figure 5.

Correlation between serum concentrations of soluble Cytotoxic T Lymphocyte Antigen-4 (sCTLA-4, expressed in ng/ml) and the spliced form of CTLA-4 transcript expression (spliced form of the CTLA-4 mRNA, analyzed in PBL and expressed as a fold change comparative with the reference obtained with the pool of 15 healthy donor PBL). This spliced form of the CTLA-4 transcript encodes for the soluble CTLA-4 molecule. The statistical test used was Spearman's r test.
