Activated Circulating T Follicular Helper Cells Are Associated with Disease Severity in Patients with Psoriasis

Figure 4

Correlations between the levels of functional markers on cTfh cells and PASI score. The ICOS and PD-1 expression on cTfh cells have positive correlations with PASI score. The positive relationships are also found between the levels of IL-21, IL-17, and IFN-γ secreted by cTfh cells and PASI score. However, the IL-10 secreted by cTfh cells has no relationship with PASI score in psoriasis patients. Correlative coefficients and values are shown.
