PDT induces systemic anti-inflammatory effects in OLP. (a) Relative number of CD137 expressing peripheral blood CD4+ T- cells is decreased 14 days after PDT treatment. Results based on analysis by flow cytometry. (b) Relative number of CD137 expressing peripheral blood CD8+ T- cells is decreased 14 days after PDT treatment. Results based on analysis by flow cytometry. (c) PDT leads to an increase of the relative number of peripheral blood γδ T cells. Results based on analysis by flow cytometry. (d) Number of peripheral blood IL-17a producing T cells is decreased 14 days after PDT treatment. Results based on ELISpot. analysis. (e) CXCL10 plasma levels are decreased 14 days after PDT treatment. Results based on ELISA analysis.*p < 0.05, **p < 0.01. PDT, photodynamic treatment.
