Fibroin, the main structural protein, and sericin, when processed, yield silk fibroin peptides, which are essentially smaller, more soluble fragments of the original fibroin protein.Meet Fibroin, the Key to Activated Silk™ Technology This reduction in molecular weight is crucial, as silk fibroin peptide possesses lower molecular weights compared to its parent protein, enhancing its bioavailability and compatibility in various biological and chemical systems.Effect of silk fibroin peptide derived from silkworm Bombyx ...

The extraction and processing of silk fibroin lead to materials with distinct characteristicsResearch progress of natural silk fibroin and the application for drug .... For instance, freeze-dried soluble Silk Fibroin can be obtained with a molecular weight ranging from 100- to significantly higher, containing 18 kinds of amino acids, with a notable concentration of glycine (Gly), alanine (Ala), and serine (Ser). A common form available is Silk Fibroin solution, approximately 50 mg/mL (5% W/V), derived from the Bombyx Mori silkworm. This solution serves as a valuable raw material, particularly in the cosmetics industry, due to its solubility in aqueous ethanol and low amino acid and salt content, as highlighted in preparations for cosmetic use.

The therapeutic potential of silk fibroin peptides is a significant area of ongoing research. Studies have demonstrated that SFP effectively inhibited the growth of lung cancer cells both in vitro and in vivo, inducing cell cycle arrest. This suggests a promising role for silk fibroin peptides in cancer therapy. Furthermore, silk fibroin peptides extracted from the domestic silkworm have shown potential in inhibiting inflammation and enhancing anti-inflammatory activity. Research by DW Kim and colleagues has investigated how silk fibroin peptide derived from the silkworm, Bombyx mori, could inhibit inflammation and enhance anti-inflammatory activity, with other studies indicating Silk fibroin upregulates the expression of several osteoblastogenic genes, such as alkaline phosphatase and collagen type-I alpha-1, pointing towards applications in bone regeneration.

Beyond direct therapeutic applications, silk fibroin peptides are being explored as advanced drug delivery systems. Their biocompatibility and ability to be functionalized make them attractive for encapsulating and delivering various therapeutic agents. An RGD-Containing Peptide Derived from Wild Silkworm is one such example, demonstrating the potential for targeted delivery. Moreover, a designed amphiphilic peptide containing the silk fibroin structure is becoming attractive as a potential drug carrier to improve the dissolvability of hydrophobic drugs in an aqueous system. This capability is further enhanced by the development of silk fibroin peptide self-assembled nanofibers, which are widely used in biomedical fields and drug delivery systems.2024年1月30日—The AP1peptideconjugated-silk fibroin/cryogel hybrid dual fiber scaffold exhibits superior granulation tissue formation, angiogenesis, ... The fabrication of an Antimicrobial Peptide-Loaded Silk Fibroin scaffold is another area where these peptides are being utilized to create advanced wound healing materials.

The cosmetic and skincare industries are also leveraging the benefits of silk fibroin peptides. Natural Silk Fibroin Peptide Hydrolysate is suggested for use in skin care and hair care applications, acting as protective and nourishing agents. The inherent properties of silk peptides and silk fibroin offer natural bioactive benefits, including potential roles in blood sugar and cholesterol regulation, and blood pressure support. The concept of EDIBLE SILK, a food-grade silk peptide obtained by hydrolyzing silk fibroin using biotechnology, further expands its application scope into nutraceuticals.

The structural integrity and processing of silk fibroin are critical for its diverse applicationsSilk–Its Mysteries, How It Is Made, and How It Is Used - PubMed Central. While silk fibroin (SF)/polymer composite materials can sometimes exhibit degraded material strength due to low miscibility, ongoing research focuses on improving these interactions. For example, peptide–graphene interactions are being explored to enhance the mechanical properties of materials incorporating Silkworm silk fibroin heavy chain protein. The development of hybrid materials, such as a hydrogel fabricated from a small functional self-assembling peptide and large silk fibroin, showcases innovative approaches to harnessing the combined properties of peptides and silk fibroin.

In summary, silk fibroin peptide represents a significant advancement in biomaterial science.
