Methylprednisolone is a corticosteroid that interacts with the glucocorticoid receptor and inhibits cortisol secretion with an IC50 of 1.7ng/ml [1]. Methylprednisolone exerts anti-inflammatory effects by inhibiting NF-kappaB and can be utilized in the treatment of tuberculosis and COVID-19 [2].
Methylprednisolone (0.5µM, 5µM, 30µM, or 50µM) could reduce HOG cell proliferation and promote HOG death in a dose-dependent manner. Methylprednisolone also decreased the expression of MBP, a marker for early mature oligodendrocytes, and inhibited myelin regeneration [3].
Methylprednisolone (25mg/kg) treatment significantly ameliorated l Aβ1-42-induced cognitive deficits in Alzheimer's disease mice as well as reduced microglia hyperactivation. Synaptic function-related genes could be upregulated by Methylprednisolone, while immune response-related genes were suppressed by Methylprednisolone. Methylprednisolone alleviated cognitive dysfunction by improving synaptic function and suppressing immune and inflammatory processes [4].

甲泼尼龙是皮质类固醇,可作用于糖皮质激素受体并抑制皮质醇分泌,其IC50为1.7ng/ml[1]。甲泼尼龙通过抑制NF-kappaB而发挥抗炎作用,并且可以运用于结核病及COVID-19的治疗[2]。
甲泼尼龙(0.5µM、5µM、30µM或50µM)处理人少突胶质细,可以以剂量依赖的方式减少 HOG 细胞的增殖,促进 HOG 的死亡。甲基强的松龙还降低了早期成熟少突胶质细胞标记物 MBP 的表达,抑制了髓鞘再生[3]。
甲泼尼龙(25mg/kg)治疗显著改善l Aβ1-42诱导的阿尔茨海默病小鼠的认知障碍,以及减少小胶质细胞的过度激活。突触功能相关基因可以被Methylprednisolone上调,而免疫反应相关基因则被Methylprednisolone所抑制。Methylprednisolone通过改善突触功能和抑制免疫和炎症过程来缓解认知功能障碍[4]。
| Cell experiment [1]: | |
|
Cell lines |
Human oligodendroglioma cell HOG |
|
Preparation Method |
HOG cells were cultured in Dulbecco's Modified Eagle's Medium at 37 °C with 5% CO2. After 24 hours of cell incubation, the medium was changed to a medium containing different doses (0.5µM, 5µM, 30µM, or 50µM) of methylprednisolone for 3, 5, and 10 days. |
|
Reaction Conditions |
0.5µM, 5µM, 30µM, or 50µM methylprednisolone for 3, 5, and 10 days |
|
Applications |
Methylprednisolone reduced the proliferation of HOG cells by reducing cell viability in a dose-dependent manner. HOG's death was also enhanced by methylprednisolone. In addition, methylprednisolone reduced the expression of the mature oligodendrocyte marker MBP at an early stage and inhibited myelin regeneration |
| Animal experiment [2]: | |
|
Animal models |
6-week-old male C57/BL6 mice (weight 18-22 g) |
|
Preparation Method |
Methylprednisolone was dissolved in saline. Mice were intragastrically administrated with methylprednisolone (25mg/kg) for 2-14 days. |
|
Dosage form |
25mg/kg, intragastrically administration |
|
Applications |
Methylprednisolone alleviated cognitive dysfunctions and inhibited the excessive activation of microglia in Aβ1-42-induced mice. Synaptic function-related genes were upregulated by Methylprednisolone, whereas immune response-related genes were suppressed by Methylprednisolone. |
