Inhibition of adiponectin-mediated gene expression in vitro by monoclonal antibodies (mAbs). To test the ability of the mAb KH4–8 to block adiponectin function, ( a ) human osteoblasts and ( b ) human umbilical vein endothelial cells (HUVECs) were treated with adiponectin (ADIPO) or KH4–8 mAb (mAb) or both. The mAb (~120 μg/mL) and recombinant adiponectin (2.5 μg/mL) were mixed and incubated for 1 h before being used to treat cells. After 24-h treatment, the culture supernatants were collected and frozen, and <t>interleukin-6</t> <t>(IL-6)</t> and IL-8 were measured by using enzyme-linked immunosorbent assay <t>(ELISA)</t> (R&D Systems, Minneapolis, MN, USA). The experiments were performed in quadruplicate. The data shown are representative of three independent experiments, and similar results were obtained with all three mAbs. Values are expressed as mean ± standard error of the mean. The expression levels of the factors were compared between groups by using the Mann–Whitney test. * P <0.05, ** P <0.01 versus the untreated group, # P <0.05, ## P <0.01 versus the group treated with adiponectin and mAb

Histamine and pro-inflammatory cytokines released by human mast cells HCMC and LAD2 were inhibited by 6-O-angeloylplenolin (6-OAP). Sensitized mast cells were pre-incubated with 6-OAP for 8 hr and then stimulated with 1 µg/ml anti-IgE for promoting degranulation and cytokine release. The effects of various concentrations of 6-OAP on degranulation as indicated by histamine release (a), <t>Interleukin-8</t> <t>(IL-8)</t> release (b), and Tumor necrosis factor-α (TNF-α) release (c) for LAD2 and human cultured mast cell (HCMC) are listed.

Summary diagram . TLR4 or TNFα receptor stimulation increases the activity of NF-κB and the expression of its target genes NR4A1–3 (NR4A), MCP-1, MIP-3α, and Relb. Loss of NR4A potentiates this induction of MCP-1, while reducing the induction of Relb and MIP-3α. Furthermore using mouse embryonic cells, we identify MIP-3α is a novel Relb target gene. Therefore, NR4A receptors act as repressors of inflammatory-NF-κB-driven MCP-1 (indicated by a red T bar) and enhancers of NF-κB-driven Relb and subsequently MIP-3α. Using a NR4A2 DNA-binding mutant reveals that NR4A2 does not require the ability to bind DNA in order to enhance/repress target genes simultaneously.

Inhibition of adiponectin-mediated gene expression in vitro by monoclonal antibodies (mAbs). To test the ability of the mAb KH4–8 to block adiponectin function, ( a ) human osteoblasts and ( b ) human umbilical vein endothelial cells (HUVECs) were treated with adiponectin (ADIPO) or KH4–8 mAb (mAb) or both. The mAb (~120 μg/mL) and recombinant adiponectin (2.5 μg/mL) were mixed and incubated for 1 h before being used to treat cells. After 24-h treatment, the culture supernatants were collected and frozen, and interleukin-6 (IL-6) and IL-8 were measured by using enzyme-linked immunosorbent assay (ELISA) (R&D Systems, Minneapolis, MN, USA). The experiments were performed in quadruplicate. The data shown are representative of three independent experiments, and similar results were obtained with all three mAbs. Values are expressed as mean ± standard error of the mean. The expression levels of the factors were compared between groups by using the Mann–Whitney test. * P <0.05, ** P <0.01 versus the untreated group, # P <0.05, ## P <0.01 versus the group treated with adiponectin and mAb

Figure Lengend Snippet: Inhibition of adiponectin-mediated gene expression in vitro by monoclonal antibodies (mAbs). To test the ability of the mAb KH4–8 to block adiponectin function, ( a ) human osteoblasts and ( b ) human umbilical vein endothelial cells (HUVECs) were treated with adiponectin (ADIPO) or KH4–8 mAb (mAb) or both. The mAb (~120 μg/mL) and recombinant adiponectin (2.5 μg/mL) were mixed and incubated for 1 h before being used to treat cells. After 24-h treatment, the culture supernatants were collected and frozen, and interleukin-6 (IL-6) and IL-8 were measured by using enzyme-linked immunosorbent assay (ELISA) (R&D Systems, Minneapolis, MN, USA). The experiments were performed in quadruplicate. The data shown are representative of three independent experiments, and similar results were obtained with all three mAbs. Values are expressed as mean ± standard error of the mean. The expression levels of the factors were compared between groups by using the Mann–Whitney test. * P <0.05, ** P <0.01 versus the untreated group, # P <0.05, ## P <0.01 versus the group treated with adiponectin and mAb

Anti-inflammatory effect of monoclonal antibodies (mAbs) KH4–8 and KH7–33 on the expression of serum pro-inflammatory cytokines of the collagen-induced arthritis mouse model. The serum levels of adiponectin, interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and receptor activator of nuclear factor-kappa Β ligand (RANKL) were analyzed by using the Luminex system. Values are expressed as mean ± standard error of the mean. The expression levels of the factors were compared between groups ( n = 8) by using the Mann–Whitney test. ** P <0.01, * P <0.05 versus normal (NOR) group, and ## P <0.01, ## P <0.05 versus the control (CON) group.

Histamine and pro-inflammatory cytokines released by human mast cells HCMC and LAD2 were inhibited by 6-O-angeloylplenolin (6-OAP). Sensitized mast cells were pre-incubated with 6-OAP for 8 hr and then stimulated with 1 µg/ml anti-IgE for promoting degranulation and cytokine release. The effects of various concentrations of 6-OAP on degranulation as indicated by histamine release (a), Interleukin-8 (IL-8) release (b), and Tumor necrosis factor-α (TNF-α) release (c) for LAD2 and human cultured mast cell (HCMC) are listed. All results were corrected for basal release. It is found that 6-OAP significantly suppressed the release of histamine, IL-8, and TNF-α in a dose-dependent manner in both LAD2 and HCMC cells. Data are presented as means ± SEM. * P <0.05 and ** P <0.01 by one-way ANOVA
