A State of Science: Actions of phycocyanine on the mechanisms of arthritis?
The numerous modes of action of phycocyanine have led to its being tested and administered in many contexts, sometimes far removed from what was previously known. It was also possible to conclude from its anti-oxidant action, and anti-inflammatory properties that it could demonstrate a possible action on arthritis contexts, especially considering the modulated and selective nature of its action. The current state of knowledge does not allow definitive conclusions to be drawn, but underlines the interest of this molecule in the fight against an extremely widespread pathology.
Phycocyanin: a possible chromoprotein obstacle to Arthritis?
Arthritis is a state of inflammation of the joints. The causes of arthritis include age, obesity, heredity, trauma, infection, immune disorders, etc. There are two main forms of arthritis, osteoarthritis and rheumatoid arthritis. Osteoarthritis is the most common form of arthritis. It is caused by the breakdown of joint cartilage and underlying bone, resulting in joint pain, swelling and stiffness. Osteoarthritis usually affects the knees, hips and hands. Rheumatoid arthritis is an autoimmune disease in which the immune system attacks the joints, causing inflammation and joint damage. It usually affects the small joints of the hands and feet, but it can also affect larger joints, such as the knees and shoulders. Rheumatoid arthritis is associated with a higher risk of heart disease and stroke. Symptoms of rheumatoid arthritis include pain, swelling and stiffness in the joints. In severe cases, rheumatoid arthritis can lead to permanent joint damage and disability.
The World Health Organization has ranked arthritis as the 15th leading cause of disability worldwide. In the United States, an estimated 1.3 million adults have physician-diagnosed arthritis. This number is expected to increase to 67 million by 2030. The cost of arthritis in the United States is estimated at $128 billion annually. This amount includes direct medical costs and indirect costs such as lost productivity.
Treatment for arthritis depends on the type of arthritis and the severity of symptoms. The main treatment for osteoarthritis is the use of non-steroidal anti-inflammatory drugs (NSAIDs). In rheumatoid arthritis, NSAIDs are usually used in combination with disease-modifying antirheumatic drugs (DMARDs). DMARDs* (Disease-modifying anti-rheumatic drugs) help reduce inflammation and joint damage. The most commonly used DMARDs for rheumatoid arthritis are methotrexate and leflunomide. Other DMARDs include sulfasalazine, hydroxychloroquine and azathioprine. Biologic DMARDs target specific components of the immune system. They include tumor necrosis factor (TNF) inhibitors, B-cell inhibitors and interleukin (IL)-6 inhibitors.
Phycocyanin is a blue protein found in algae and cyanobacteria, which has many pharmacological properties, such as antioxidant, anti-inflammatory, anticancer and hepatoprotective activities. In this article, we describe the selective modulating action of phycocyanin on arthritis.

Phycocyanine as an antioxidant
The antioxidant property of phycocyanine is mainly due to its ability to scavenge free radicals. Free radicals are molecules that contain unpaired electrons in their outer orbits. Free radicals are constantly generated in the human body as a result of metabolism. However, excessive production of free radicals can lead to cell and tissue damage. Oxidative stress refers to the imbalance between the production of free radicals and the body's ability to eliminate free radicals. This can lead to cell damage and inflammation. Oxidative stress has been linked to many chronic diseases, such as diabetes, cardiovascular disease and neurodegenerative diseases.
The antioxidant property of phycocyanin is attributed to its superoxide anion radical scavenging activity. The superoxide anion radical is the most common free radical generated in the body. Phycocyanin has been shown to trap the anionic superoxide radical in a dose-dependent manner. The superoxide anion radical scavenging activity of phycocyanin is comparable to that of ascorbic acid, a well-known antioxidant. The scavenging activity of phycocyanin against other free radicals, such as hydroxyl radicals, nitric oxide and hydrogen peroxide, has also been reported.
The antioxidant activity of phycocyanin is not limited to the capture of free radicals. It also includes the inhibition of lipid peroxidation and the modulation of the expression of antioxidant enzymes. Lipid peroxidation is the oxidative breakdown of lipids. It is a common form of oxidative damage to cell membranes. Phycocyanin has been shown to inhibit lipid peroxidation in a dose-dependent manner. It has also been reported to upregulate the expression of the antioxidant enzymes superoxide dismutase and glutathione peroxidase.
Phycocyanine as an anti-inflammatory agent
The anti-inflammatory property of phycocyanine is due to its ability to inhibit the expression of pro-inflammatory cytokines and the activity of cyclooxygenase (COX) enzymes. Pro-inflammatory cytokines are signaling molecules that play a role in inflammation. They are released by the immune system in response to pathogens and tissue damage. They activate immune cells to eliminate pathogens and damaged cells and initiate the healing process. However, excessive production of pro-inflammatory cytokines can lead to inflammation. Proinflammatory cytokines that are involved in inflammation include tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6).
COX enzymes play a role in the synthesis of prostaglandins, which are molecules involved in inflammation. There are two isoforms of COX enzymes, COX-1 and COX-2. COX-1 is constitutively expressed in most cells and is involved in the synthesis of prostaglandins that regulate physiological functions such as gastric secretion and platelet aggregation. COX-2 is not expressed in most cells under normal conditions, but is upregulated in response to cytokines and growth factors. COX-2 is involved in the synthesis of prostaglandins that are involved in inflammation.
Phycocyanin has been shown to inhibit the expression of TNF-α, IL-1β and IL-6 in macrophages and microglia as well as inhibit the expression of COX-2 in macrophages. The anti-inflammatory property of phycocyanin is not limited to macrophages and microglia. It has also been reported in chondrocytes and synovial cells.
Selective modulating action of phycocyanine on arthritis
The selective modulatory action of phycocyanin on arthritis is mediated by its antioxidant and anti-inflammatory properties. The anti-inflammatory property of phycocyanin was found to be selective in inhibiting the expression of pro-inflammatory cytokines and COX-2 in macrophages and microglia, but not in chondrocytes and synovial cells. This is important because selective inhibition of the inflammatory response in macrophages and microglia would reduce joint inflammation without affecting normal chondrocyte and synovial cell functions. The selective modulating action of phycocyanine on arthritis has been demonstrated in animal models of osteoarthritis and rheumatoid arthritis. In the osteoarthritis animal model, phycocyanine has been shown to reduce the severity of osteoarthritis and rheumatoid arthritis by inhibiting the expression of pro-inflammatory cytokines and COX-2 activity.
Future prospects
The selective modulatory action of phycocyanin on arthritis is a promising discovery. The development of phycocyanine as a treatment for arthritis is of great interest but it would be wise to characterize and assess its effects in humans on the expression of pro-inflammatory cytokines and COX-2 in macrophages, microglia, chondrocytes and synovial cells.
*Phycocyanine, due to the diversity of its action modalities, was quickly studied in the context of the prevention of neurological dysfunctions, the stimulation of astrocytes, and the reconfiguration of the cerebral environment."
