Protein microarray demonstrated that inhibition of mediator release involves profound reductions in the activation of signaling molecules involved in mediator release and oxidative stress. Follow-up studies demonstrated that the tyrosine phosphorylation of Syk was dramatically inhibited in Ag-challenged cells first incubated with fullerenes. In addition, fullerene preincubation significantly inhibited IgE-induced elevation in cytoplasmic reactive oxygen species levels. Furthermore, fullerenes prevented the in vivo release of histamine and drop in core body temperature in vivo using a MC-dependent model of anaphylaxis. These findings identify a new biological function for fullerenes and may represent a novel way to control MC-dependent diseases including asthma, inflammatory arthritis, heart disease, and multiple sclerosis.

Reduces Osteoarthritis

The applications of buckminsterfullerene C60 and derivatives in orthopaedic research

Qihai Liu 1, Quanjun Cui, Xudong Joshua Li, Li Jin

Buckminsterfullerene C60 and derivatives have been extensively explored in biomedical research due to their unique structure and unparalleled physicochemical properties. C60 is characterized as a “free radical sponge” with an anti-oxidant efficacy several hundred-fold higher than conventional anti-oxidants. Also, the C60 core has a strong electron-attracting ability and numerous functional compounds with widely different properties can be added to this fullerene cage. This review focused on the applications of C60 and derivatives in orthopaedic research, such as the treatment of cartilage degeneration, bone destruction, intervertebral disc degeneration (IVDD), vertebral bone marrow disorder, radiculopathy, etc., as well as their toxicity in vitro and in vivo. 

Inhibition of Arthritis

Water-soluble fullerene (C60) inhibits the development of arthritis in the rat model of arthritis

Kazuo Yudoh,1 Rie Karasawa,1 Kayo Masuko,2 and Tomohiro Kato2

Recently, it has been demonstrated that oxygen free radicals have an important role as a signaling messenger in the development of inflammation and osteoclastogenesis, suggesting the implication of oxygen free radicals in the pathogenesis of arthritis. The aim of this study was to examine the potential of a strong free-radical scavenger, water-soluble fullerene (C60), as a protective agent against synovitis in arthritis, both in vitro and in vivo

Reduces Osteoarthritis

Water-soluble C60 fullerene prevents degeneration of articular cartilage in osteoarthritis via down-regulation of chondrocyte catabolic activity and inhibition of cartilage degeneration during disease development

The aim of this study was to examine the potential of a strong free-radical scavenger, water-soluble fullerene (C60), as a protective agent against catabolic stress-induced degeneration of articular cartilage in OA, both in vitro and in vivo.

Reduce Inflammation

Fullerol nanoparticles suppress inflammatory response and adipogenesis of vertebral bone marrow stromal cells–A potential novel treatment for intervertebral disc degeneration

Qihai Liu, PhD, Li Jin, MD, PhD, Francis H. Shen, MD, Gary Balian, PhD, and Xudong Joshua Li, MD, PhD

In conclusion, we believe that this is the first observation that fullerol, a potent antioxidant agent, suppresses IL-1 β-induced ROS and inflammatory cytokine production, inhibits the adipogenic differentiation of vBMSCs in vitro and, therefore, may prevent vertebral fatty marrow deposition and inflammatory responses during disc degeneration.
