Effect of CSP-AU1 on MAP kinase phosphorylation. PBMCs were incubated for 30 min with 250 μg/ml of CSP-AU1, and levels of kinase phosphorylation were evaluated using a phospho-MAPK array kit. The data are presented as mean ± SD of duplicate samples from one experiment. Statistically significant differences (* p<0.05) between PBS-treated cells and cells treated with CSP-AU1 are indicated.

Cytokine profile of splenic and lymph node (LN) cells isolated from PBS- or CSP AU1-treated EAE mice. Splenic and LN cells were prepared from mice at day 17 after immunization with MOG35-55 peptide. These cells (5 × 106 cell/ml) were restimulated with 10 μg/ml MOG35-55 for 4 days, cell-free supernatants were collected, and extracellular cytokines were quantified by ELISA. Mean cytokine concentrations from 3–5 cultures ± S.D. are shown. Statistically significant differences (* p<0.05; ** p<0.001) between cells, isolated from PBS- and CSP-AU1-treated EAE mice are indicated.

Cytokine array analysis of PBMC cytokine production after treatment with Clerodendrum polysaccharide fractions CSP-AU1 and CSP-NU1. Human PBMCs were incubated for 24 hr with 250 μg/ml of CSP-AU1 (open bars) and CSP-NU1 (hatched bars), or 200 ng/ml of LPS (solid bars), and production of cytokines in the supernatants was evaluated using a MultiAnalyte ELISArray kit. Cytokine expression is shown as fold increase compared to background (PBS-treated cells). The data are presented as mean ± SD of duplicate samples from one experiment that is representative of two independent experiments. Statistically significant differences (* p<0.05) between PBS-treated cells and cells treated with polysaccharide fractions or LPS are indicated.

Effect of Clerodendrum polysaccharide fractions on serum cytokines. Balb/c mice (n=4) were treated by i.p. injection with polysaccharide fractions CSP-AU1, CSP-AU2, CSP-NU1 (single dose of 250 mg/kg in 100 μl of PBS), LPS (single dose of 500 μg/kg in 100 μl of PBS), or PBS (100 μl). After 2 hr, mice were sacrificed, and serum was collected. Serum cytokine levels were evaluated using a MultiAnalyte ELISArray kit. Cytokine levels are shown as fold increase compared to background (PBS-treated mice). Inset A. CSP-AU1 was administrated i.p. (single dose 250 mg/kg), mice (n=3) were sacrificed at the indicated time points, and serum was collected. Inset B. The indicated doses of CSP-AU1 were administrated i.p., the mice (n=3) were sacrificed after 2 hr, and serum was collected. Serum TNF levels were evaluated using ELISA. For the Figure and Insets, the data are presented as mean ± S.D. of triplicate samples from different mice and are representative of two independent experiments. Statistically significant differences (* p<0.05) between animals treated with PBS and CSP-AU1 or LPS are indicated.
