主な方法:
- 84匹の雄ウイスターネズミは,トルション (4時間) と再注射 (24時間) を受けた.
- リネゾリド (3~100 mg/ kg) を投与し,組織病理学,酸化ストレスマーカー (MDA,SOD) およびTNF-αレベルによって評価した.
- TLR-4,MAPK,NF-κB経路を含むメカニズムは,シリコ分子ドッキングと共に調査されました.
主要な成果:
- リネゾリドは丸の損傷を大幅に軽減し,50 mg/ kgで最適な効果が観察されました.
- 薬はマロンディアルデヒド (MDA) と腫瘍死滅因子-α (TNF-α) を減らし,同時にスーパーオキシドディスミューターゼ (SOD) の活性を増大させた.
- ラインゾリドはTLR- 4/ NF- kB経路を抑制し,最大64%のMDA,77%のTNF- α,56%のNF- kB,および47%のTLR- 4の減少を示し,SODは47%増加した.
- シリコ分析では,ラインゾリドがTLR-4経路タンパク質に強く結合することを予測した.

NF-κB-dependent Signaling Pathway
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Tissue Injury: Inflammation and Repair
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Inflammatory Response
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,...
