Effects of L-pyroglutamic acid on arthritis variables in collagen-induced arthritis mice. a Serum anti-CII IgG was measured by ELISA at day 56. b Arthritis scores were assessed every 3 days starting after day 21. c Left ankle swelling was assessed every 3 days starting after day 21. d Serum IL-6 was measured by ELISA at day 56. e Serum IL-17A was measured by ELISA at day 56. f Serum G-CSF was measured by ELISA at day 56. g Serum eotaxin was measured by ELISA at day 56. Values are the mean ± SEM. “*” = P<0.05; “**” = P<0.01, “ns” = P≥0.05
