Fig. 7From: Parkinson’s disease patients have a complex phenotypic and functional Th1 bias: cross-sectional studies of CD4+ Th1/Th2/T17 and Treg in drug-naïve and drug-treated patientsCytokine production by Teff cells in HS and PD patients. Cytokines were measured in supernatants of resting cells (white columns) and of cells stimulated with PHA (black columns). Data are means ± SD of n = 4–9 subjects. *P < 0.05 and **P < 0.01 vs resting cells; # = P < 0.05 and ##P < 0.01 vs HSBack to article page
