概括
在牛皮患者中,阿普雷米拉斯特治疗显著降低了骨质结晶和RANKL水平,这表明它通过抑制PDE4来抵消骨质再吸收. 这为治疗牛皮骨病提供了潜在的临床益处.
科学领域:
- 免疫皮肤学 免疫皮肤学
- 骨生物学 骨生物学 骨生物学
- 药理学 药理学是指药理学的学科.
背景情况:
- 牛皮炎与关节和骨的改变有关,这是一个涉及骨质细胞 (OC) 差异化的过程.
- 骨质细胞对骨再吸收至关重要,由RANKL-RANK信号传递和循环AMP (cAMP) 途径进行调节.
- 固酶 (PDEs) 调节cAMP水平,而PDE4抑制剂apremilast用于牛皮 (Pso) 和牛皮性关节炎 (PsA).
研究的目的:
- 为了研究阿普雷米拉斯特对中度至重度牛皮的患者骨质细胞形成的影响.
- 为了评估apremilast治疗后血清RANKL水平的变化.
- 探索PDE4在牛皮中亲骨质细胞生成过程中的作用.
主要方法:
- 十七名患有中度至重度牛皮的患者接受了全身阿普雷米拉斯治疗.
- 周围血液单细胞/巨细胞在基线和52周后被分析以检测体外骨质细胞生成.
- 血清RANKL水平在基线和经过52周的阿普雷米拉斯特治疗后进行测量.
主要成果:
- 与基线相比,52周的阿普雷米拉斯特治疗显著降低了骨质细胞 (OC) 和RANKL水平.
- 一项细分分析表明,生物经验患者的骨质细胞前体 (OCP) 数量和血RANKL水平低于bionaïve患者.
- 这些发现表明,阿普雷米拉斯特调节了参与骨再吸收的关键途径.

Osteoclasts in Bone Remodeling
2.8K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Remodeling
38.1K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors
121
Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...
