- 牙周病学 牙周病学
- 药理学 药理学是指药理学的学科.
背景情况:
- 糖尿病相关的牙周炎涉及复杂的炎症反应.
- 巨细胞在牙周炎的发病过程中起着至关重要的作用,具有M1 (促炎症) 和M2 (促溶解) 现型.
- 需要新的治疗药物来调节巨细胞两极分化并解决炎症.
研究的目的:

Inflammatory Response
2.1K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
