ln Vitro |
Glucocorticoids remain the most widely used immunosuppressive and anti-inflammatory drugs, yet substantial gaps exist in our understanding of glucocorticoid-mediated immunoregulation. To address this, we generated a pathway-level map of the transcriptional effects of glucocorticoids on nine primary human cell types. This analysis revealed that the response to glucocorticoids is highly cell type dependent, in terms of the individual genes and pathways affected, as well as the magnitude and direction of transcriptional regulation. Based on these data and given their importance in autoimmunity, we conducted functional studies with B cells. We found that glucocorticoids impair upstream B cell receptor and Toll-like receptor 7 signaling, reduce transcriptional output from the three immunoglobulin loci, and promote significant up-regulation of the genes encoding the immunomodulatory cytokine IL-10 and the terminal-differentiation factor BLIMP-1. These findings provide new mechanistic understanding of glucocorticoid action and emphasize the multifactorial, cell-specific effects of these drugs, with potential implications for designing more selective immunoregulatory therapies[2].

ln Vivo |
Methylprednisolone acetate (30 mg/kg, intramuscular injection; additional oral dose of 13 mg/kg, for 10 consecutive days) combined with LPS induces the typical characteristics of early AVN of the femoral head [2].
|
Cell Assay |
Bone marrow-derived mononuclear cells were collected by incubation in hemolysis solution. Mononuclear cells were fixed in ethanol (70%) for 24 hours and stained with propidium iodide for 10 minutes. Cell cycle analysis was done by flow cytometry[2].

Animal Protocol |
Animal/Disease Models: Femoral necrosis mouse model methylprednisolone and lipose-induced head [2]
Doses: 30 mg/kg; 13 mg/kg for 10 days Route of Administration: 30 mg/kg, intramuscularinjection ;Additional oral dose of 13 mg/kg for 10 days resulted in chondrocyte degeneration and fibrocartilage expression after 7 weeks. The density of CD31 and VEGF-R2 markers increased in the femoral head. Adult mice were randomly divided into two groups: experimental and control. Group A (the experimental group) was given (via intramuscular injection) 10 mg/kg of lipopolysaccharide (LPS) and 30 mg/kg of methylprednisolone (MPS). Each mouse additionally received MPS in divided oral doses of 13 mg/kg for 10 consecutive days. Group B (the control group) received normal saline at the same location and same volume as those in Group A. Histological changes of the femoral heads were observed by electron microscopy at 3, 5, and 7 weeks after the last chemical injection. The percentage of empty lacunae was measured randomly and the expression of fibrocartilage was evaluated using an image analyzing system. The expression of CD31 and VEGF-R2 were observed by immunohistochemistry. The bone marrow-derived mononuclear cells were stained with propidium iodide and cell cycle was analyzed by flow cytometry.[2] |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
