Anti-inflammatory activities of Naticol®
demonstrate benefits in ageing
Author: Dr. Christelle Bonnet
Ageing may be considered as the accumulation of diverse deleterious changes in cells and tissues (skin, joints…). One of the major changes that occur during ageing is the dysregulation of the immune response, leading to a chronic systemic inflammatory state. Among the dysregulated proinflammatory mediators, cytokines and chemokines are major culprits in the development of chronic inflammation and the immunosenescence process.
For instance, interleukin (IL)-6, tumor necrosis factor (TNF)-α, and their receptors, are upregulated in aged tissues and cells (Bruunsgaard et al., 2003). Michaud et al. have shown that two to four-fold elevations in the circulating levels of inflammatory cytokines, such as TNF-α, IL-6, and IL-1β are typically observed in the elderly compared to the young.
Skin ageing answers to this chronic inflammatory state. Additionally, skin ageing, in particular, skin appearance being a primary indicator of age, with skin becoming unevenly coloured, lax, dry as it ages, a solution targeting skin appearance and specifically inflammation resolution seems relevant.
We believe collagen peptides can make an important difference in the way the skin looks and even in how well it ages. According to the literature, collagen peptides may slow down the collagen disorganization and destruction associated with dermal atrophy and skin aging. Scanning electron microscopic examination shows that the number and width of collagen fiber bundles decreases with age.
Naticol®, natural fish collagen peptides developed by Weishardt group is clinically substantiated to improve skin elasticity and reduce skin wrinkle appearance through an acceleration of collagen synthesis and inflammation resolution.
Within the joint, intra-articular administration of collagen in the knee in patients with osteoarthritis significantly decreases local inflammation (increase in T regs, IL-10 and decrease in IL-1b) and attenuates the symptoms inherent to the pathology (Furuzawa-Carballeda et al., 2012). Similarly, oral administration of collagen in mice with post-traumatic osteoarthritis inhibits synovial inflammation and induces cartilage regeneration (Dar et al., 2016). Naticol® has also clinically demonstrated its benefits in physical function to alleviate osteoarthritis symptoms. In metabolic disorders, it is suggested that the oral administration of collagen improves metabolism by directly targeting inflammatory processes (Astre et al., 2018).
Interestingly, it has also been shown that collagen hydrolysates inhibit zymosan- induced inflammation (Hartog et al., 2013).
In this article, we would like to point out how Naticol® (specific fish collagen peptides) may exert its benefits in skin beauty and articular comfort through an acceleration of collagen synthesis and anti-inflammatory activities.
In vitro benefits of Naticol® on matrix metalloprotease and collagen synthase expression
Human monocyte-derived macrophages (h-MDMs) and keratinocytes (HaCat) were co-cultivated in transwell culture system. The cells were stimulated with LPS (100ng/ml) to induce a
pro-inflammatory phenotype and then were traited by Naticol®.
The expression of Collagen Synthase 3 (enzyme involved in collagen production), of Metallopeptidase 13 (MMP13 involved in the breakdown of extracellular matrix and tissue remodeling), TGFb and IL-10 (anti-inflammatory and proresolutive cytokines) were evaluated by real-time qPCR.
Results showed a significant increase of the collagen synthesis through a decrease of the matrix metalloproteases and an increase of the collagen synthesis.
Naticol® and anti-inflammatory activities
Research has been conducted to determine the effects of collagen peptides on inflammation. Indeed, it has been shown, in vivo, that MR (Mannose Receptor) specifically expressed by M2-like macrophages is responsible for the recognition and endocytosis of collagen across the fibronectin type II domain and recognizes both native collagen and hydrolyzed collagen peptides (Curino et al., 2005; Eichele et al.,2017; Engelholm et al., 2009; Madsen et al., 2013; Malovic et al.,2007; Melander et al., 2015; Napper et al., 2006; Seikh et al. 2000). In our experiment, Naticol® was associated with lower levels of TNF-β and IL-1β pro-inflammatory cytokines. The attenuated inflammation by Naticol® treatment was also supported by induced TGFb and IL-10 anti-inflammatory cytokines secretion.
Anti-inflammatory properties of Naticol® have been demonstrated in pre-clinical studies. Consequently, Naticol® is the ideal ingredient delivering wellbeing and anti-ageing benefits.
