Article Title: C-Reactive Protein Suppresses the Th17 Response Indirectly by Attenuating the Antigen Presentation Ability of Monocyte Derived Dendritic Cells in Experimental Autoimmune Encephalomyelitis

doi: 10.3389/fimmu.2021.589200

Figure Lengend Snippet: The Th17 responses are suppressed by one-dose CRP injection in WT EAE mice.Splenocytes were isolated form EAE and EAE CRP mice, then re-stimulated with 50 ug/ml MOG 24 h for qPCR, 72 h for ELISA and FACS. (A) Th17 relevant cytokine (IL-17) and transcription factor (ROR γ t) were examined by qPCR and ELISA (n = 8). (B) Th1 relevant cytokine (IFN- γ ) and transcription factor (T-bet) were measured by qPCR and ELISA (n = 8). (C) Th2 relevant cytokine (IL-4) and transcription factor (GATA-3) were detected by qPCR and ELISA (n = 8). (D) Th2 relevant cytokine (IL-10) and transcription factor (Foxp3) were tested by qPCR and ELISA (n = 8). (E) Th17 (CD4 + IL-17 + ) and Th1 (CD4 + IFN- γ + ) cells were examined by FACS (n = 3). Data are presented as mean ± SEM; p < 0.05 was considered statistically significant.

Figure Lengend Snippet: CRP reduces Th17 responses in splenocytes from WT mice.Splenocytes and CD4 + T cells were isolated from WT mice to distinguish the indirect and direct regulations of CRP on Th17. (A) The protein expression levels of IL-17 and IFN- γ were measured with CRP treatment in both splenocytes and CD4 + T cells by ELISA (n = 6). (B) The mRNA expression levels of IL-17 and IFN- γ were measured with CRP treatment in both splenocytes and CD4 + T cells by qPCR (n = 4). (C) Splenocytes and CD4 + T cells were cultured with CRP in Th17 and Th1 polarization conditions, then ROR γ t, T-bet, p-STAT-3, and p-STAT-1 were examined by WB. (D) The quantitative and statistical analysis of the WB results was presented (n = 3). Data are presented as mean ± SEM; p < 0.05 was considered statistically significant.
