Image caption:
T-cell recruitment after immune complex formation. OVA-immunized mice received a unilateral injection of OVA into the striatum and brain tissue was assessed for presence of CD3-positive T cells at 24 h (a), day 7 (b) and day 14 (c) after OVA injection. Non-immunized mice were used as control (d, g). OVA-immunized wild type (e, h) and Fcγ−/− (f, i) mice received a unilateral injection of OVA into the striatum and tissue was analysed for CD3 (d, e, f) or CD11b (g, h, i) immunoreactivity at 7 days. Representative data of n = 2–3 per time point are shown. Scale bar 100μm

Rat anti Mouse CD3 antibody, clone KT3 (MCA500G) used to coat plates and stimulate cells to measure cytokine production in vitro
Image caption:
Effect of baicalein on IL-4 and IL-13 production in the culture supernatant of CD3 stimulated splenocytes. Balb/c males (6 weeks old) were used and ovalbumin was injected intraperitoneally for 0, 7, 14, 21, and 28 days to Balb/c (n = 5). The baicalein, containing 100 mg of baicalein/kg body weight per day dissolved in 0.4% polyethylene glycol in 0.5% EtOH, was applied topically on a daily basis for four weeks. Cytokine measurements in the spleen cells (2 × 106 mL−1) were cultured for 48 hrs in a culture dish, which had been coated with CD3 mAb. Then, IL-4 and IL-13 levels were measured. The production of IL-4 and IL-13 was measured with ELISA in the culture supernatant. All measurements were made in triplicate and all values are represented as mean ± SD. Nr, normal; OVA-CT, control treated with only ovalbumin; Dexa., dexamethasone; SB, Scutellaria baicalensis Georgi extract. * p<0.05,** p<0.01, *** p<0.001 and showed a significant difference from OVA-CT.
