Figure 2. Antibody responses in RP patients compared with non-RP patients. (a) The downregulated specific IgM response in RP patients. (b) The upregulated specific IgM response in RP patients. (c) The upregulated specific IgG response in RP patients. (d) The downregulated specific IgG response in RP patients. The data in (a) (b) (c) (d) were presented as mean log2 (Fluorescence intensity) ± SD, (e) Comparison of neutralizing ability between non-RP (n=113) and RP patients (n=21). p -value was calculated by two-sided t test. *, p < 0.05, **, p < 0.01, and ***, p< 0.001.
