Summary of the article “Protective Effect of Resveratrol on Knee Osteoarthritis and its Molecular Mechanisms: A Recent Review in Preclinical and Clinical Trials” from PubMed Central (2022)

This article is a review of research on Resveratrol (RES) and its role in helping to prevent/slow down osteoarthritis (Knee Osteoarthritis: KOA), both from laboratory experiments. (preclinical) and clinical studies in humans

The essence of the article

What is knee osteoarthritis (KOA)?

KOA is a very common chronic osteoarthritis. Especially in the elderly people who are overweight or those with a history of knee injuries

The main characteristics are

Articular cartilage is destroyed.

There is inflammation of the joint lining.

The bone beneath the joint surface changes abnormally.

Causes pain, joint stiffness, and decreased mobility.

Currently, the main treatment focuses only on “reducing pain,” but there is no way to truly stop the deterioration.

What is Resveratrol?

Resveratrol is a natural polyphenol found in abundance.

Red grapes, mulberries and some medicinal plants

Its outstanding effect is

Antioxidants

anti-inflammatory

resist cell death

Helps protect the heart and blood vessels

Slow down cell degeneration

Therefore, it has been heavily studied in osteoarthritis.

Important mechanism by which Resveratrol helps osteoarthritis

1. Reduce inflammation (Anti-inflammatory)

Resveratrol reduces inflammatory substances such as

IL-1β

IL-6

TNF-α

COX-2

iNOS

and reduce cartilage-destroying enzymes, such as

MMP-1

MMP-3

MMP-13

This results in slower destruction of the joint.

2. Reduce the death of cartilage cells. (Anti-apoptosis)

cartilage cells Chondrocytes are important cells in maintaining joint conditions.

Resveratrol helps

Reduce cell death

increases survival of chondrocytes

Prevents cartilage degeneration

Thus helping to slow down the progression of the disease.

3. Maintain cartilage balance (Cartilage Homeostasis)

Helps increase the creation of important cartilage substances such as

Type II collagen (COL-II)

Aggrecan (AGG)

and reduce the decay of extracellular matrix

This allows the joint to remain strong and flexible.

4. Stimulates Autophagy (removal of waste cells)

Resveratrol stimulates the autophagy process.

which helps

Eliminate dead cells

Reduce cumulative damage

Slow down the deterioration of joints

It is considered a very important mechanism in osteoarthritis.

Results from human studies

Clinical research has found that

Using Resveratrol along with standard treatment helps.

Reduce pain

Reduce inflammation

Helps the work of the advantages improve.

Reduces inflammatory markers in the blood

Brief summary

Resveratrol is a natural substance with high potential to help delay osteoarthritis. It works through 4 main mechanisms.

Reduce inflammation

Reduce the death of cartilage cells

Maintain cartilage balance

stimulate cell repair

Therefore, it is a “supplement for osteoarthritis care” that is safer than long-term use of NSAIDs as painkillers.
