GOLD-Induced Cytokine (GOLDIC): A Game-Changer Orthobiologic in Regenerative Medicine

Abstract

Due to the Industry 4.0 and Industry 5.0 revolutions, researchers, clinicians, and regenerative medicine experts are exploring the plausibility of regenerating diseased or degenerated tissues to regain their near-normal biomechanical properties. In the past three decades, research on “Tissue Engineering and Regenerative Medicine” (TERM) has attained various milestones in clinical translation from bench to bedside. The regulatory bodies of various countries and states are working on the ethical use and guidelines for the production and storage of various cellular and acellular products. Platelets and platelet-derived by-products play a significant role in TERM. The growth factors and cytokines present in platelets regenerate the tissue of interest. In this connotation, a newer orthobiologic called “GOLD-induced cytokine” (GOLDIC) has become a product of interest among various regenerative medicine experts and researchers around the globe. Due to its potent anti-inflammatory action and potential systemic side effects, gold has been withdrawn from the management panel for rheumatoid arthritis. With the knowledge of its anti-inflammatory properties, researchers explored the utility of gold for tissue regeneration.

Editorial

In the dynamic confluence of cutting-edge technological advancements and regenerative medicine, the convergence of Industry 4.0 and Industry 5.0 has catalyzed a transformative breakthrough known as GOLD-induced cytokine (GOLDIC) therapy. This innovative paradigm presents a renewed beacon of hope for patients grappling with degenerative diseases and tissue injuries by harnessing the intricate interplay of platelets and their derived products. Through orchestrating tissue regeneration and adept management of inflammation-driven pathologies, GOLDIC therapy stands as a vanguard in medical innovation.

Historical genesis

The roots of GOLDIC therapy can be traced back to the visionary German physicist Ulrich Schneider, who unveiled the latent potential of hydrophilic gold particles within tissue engineering. This revelation marked the inception of a symphony of intricate molecular responses that yield a serum teeming with anti-catabolic and anabolic factors, constituting the fundamental tissue regeneration bedrock. The revival of gold, once associated with rheumatoid arthritis management but relegated due to systemic side effects, symbolizes the resilience of scientific exploration and the transformative potency of novel perspectives.

Evolutionary trajectory

GOLDIC therapy emulates the harmonious convergence of material science, biomedical engineering, and clinical innovation. Its evolutionary trajectory underscores a remarkable odyssey from laboratory discovery to tangible patient-centric benefits. Through the amalgamation of Industry 4.0 and Industry 5.0 technologies with the principles of regenerative medicine, novel therapeutic paradigms have transcended the boundaries of erstwhile scientific conjecture, propelling the frontiers of tissue engineering and regenerative medicine.

Mechanistic ingenuity

At the core of GOLDIC therapy lies the exquisite orchestration of platelets and their ensuing products. Hydrophilic gold particles are instigators, creating a harmonious ensemble of molecular cascades that culminate in a serum enriched with a panoply of growth factors and cytokines. This potent cohort synergistically expedites tissue regeneration while displaying formidable anti-inflammatory attributes. At the heart of this therapeutic approach lies an intricate mechanistic interplay, elucidating how platelets and hydrophilic gold particles orchestrate a transformative response for tissue regeneration and inflammation management [1]. This serum emerges as a paradigm-shifting therapeutic elixir, divided from gold compounds.

Steps in preparation for GOLDIC

Synthesis of hydrophilic gold particles; blood culturing and interaction with hydrophilic gold particles; platelet activation and growth factor release; serum collection and processing

GOLDIC treatment starts with taking a sample of the patient’s blood. This blood is now prepared using GOLDIC tubes, which include specially designed gold particles and a special filter to prevent these particles, cells, and platelets from being injected with the processed, enriched in cytokines and growth factors serum. During the incubation process (24 hours), gold particles act as catalysts for monocytes to produce the whole spectrum of autologous cytokines, which is the most important part of the process. The GOLDIC tubes filled with patients’ blood after the incubation will be centrifuged to separate serum from the other blood components. This serum, enriched with growth factors and important cytokines, is then provided for injection.

Quality control and standardization

Rigorous quality control measures are employed to ensure the consistency and potency of the serum obtained from different patient samples. This step involves assessing the concentrations of key growth factors and cytokines to guarantee the therapeutic efficacy of the final product.

Clinical administration

The prepared serum, which is now abundant in bioactive molecules capable of promoting tissue regeneration and modulating inflammation, is administered to the patient. Depending on the medical condition being treated, the serum may be delivered directly to the target tissue or systemically through an intravenous infusion.

Once introduced into the bloodstream, the hydrophilic gold particles serve as initiators of a multifaceted cascade of molecular events. Their unique surface characteristics facilitate interactions with blood components, particularly platelets. This interaction triggers platelet activation, culminating in a complex sequence of intracellular signaling pathways. Within activated platelets, these signaling pathways converge on releasing various bioactive molecules, including growth factors and cytokines. Among the prominent players are platelet-derived growth factor (PDGF), transforming growth factor beta (TGF-β), vascular endothelial growth factor (VEGF), and interleukins (ILs), each contributing to distinct facets of tissue regeneration and immunomodulation. PDGF, for instance, stimulates cell proliferation and migration, promoting tissue repair and regeneration. TGF-β regulates cell differentiation and extracellular matrix deposition, which is crucial for tissue remodeling and wound healing. VEGF augments angiogenesis, fostering the formation of new blood vessels to nourish regenerating tissues. ILs orchestrate immune responses, aiding in the recruitment of immune cells for tissue repair and curtailing inflammation.

The resulting serum, enriched with these potent bioactive molecules, exerts multifunctional effects on the targeted tissues. It accelerates the recruitment and proliferation of progenitor cells necessary for tissue repair, facilitates the remodeling of the extracellular matrix, and enhances vascularization for improved nutrient and oxygen supply. Simultaneously, the serum exerts immunomodulatory effects, dampening excessive inflammation while preserving the measured immune response necessary for healing.

Moreover, the presence of hydrophilic gold particles during these orchestrated events potentiates the therapeutic impact. Their precise role involves modulating signaling pathways and cellular responses, possibly through their unique physicochemical properties and interactions with cellular membranes. However, this promising therapeutic paradigm also presents challenges, particularly with regard to potential side effects (like pain, swelling, recurrence of symptoms, and malignant transformation of benign pathologies) and the need for comprehensive safety assessments. Addressing these concerns through rigorous research and methodologically sound clinical trials is essential to substantiate the efficacy and safety of GOLDIC therapy.
