Abstract
Islet transplantation is a curative treatment for patients suffering from type 1 diabetes and has the potential to replace current treatment strategies involving the exogenous administration of insulin. Despite this potential, there are many hurdles in achieving successful long-term graft survival due to autoimmune and foreign body reactions leading to graft rejection coupled with donor shortage and potential adverse effects from the need for long-term administration of immunosuppressive drugs. As a result, various approaches have been proposed to increase the viability and function of islet grafts during isolation and ex vivo culture with the use of growth factors, hormones, and other therapeutic agents. In addition, other strategies have addressed how to enhance or maintain islet graft performance after implantation with improvements on immunosuppressive drug regimens and the use of biomaterials to encapsulate and protect the cells from graft rejection. This review focuses on the recent advances in strategies to improve islet viability and function with the addition of exogenous compounds and the implementation of conformal coating as a promising tool for immunoprotection of islet transplants.
期刊介绍：
Advanced NanoBiomed Research will provide an Open Access home for cutting-edge nanomedicine, bioengineering and biomaterials research aimed at improving human health. The journal will capture a broad spectrum of research from increasingly multi- and interdisciplinary fields of the traditional areas of biomedicine, bioengineering and health-related materials science as well as precision and personalized medicine, drug delivery, and artificial intelligence-driven health science.
The scope of Advanced NanoBiomed Research will cover the following key subject areas:
▪ Nanomedicine and nanotechnology, with applications in drug and gene delivery, diagnostics, theranostics, photothermal and photodynamic therapy and multimodal imaging.
▪ Biomaterials, including hydrogels, 2D materials, biopolymers, composites, biodegradable materials, biohybrids and biomimetics (such as artificial cells, exosomes and extracellular vesicles), as well as all organic and inorganic materials for biomedical applications.
▪ Biointerfaces, such as anti-microbial surfaces and coatings, as well as interfaces for cellular engineering, immunoengineering and 3D cell culture.
▪ Biofabrication including (bio)inks and technologies, towards generation of functional tissues and organs.
▪ Tissue engineering and regenerative medicine, including scaffolds and scaffold-free approaches, for bone, ligament, muscle, skin, neural, cardiac tissue engineering and tissue vascularization.
▪ Devices for healthcare applications, disease modelling and treatment, such as diagnostics, lab-on-a-chip, organs-on-a-chip, bioMEMS, bioelectronics, wearables, actuators, soft robotics, and intelligent drug delivery systems.
with a strong focus on applications of these fields, from bench-to-bedside, for treatment of all diseases and disorders, such as infectious, autoimmune, cardiovascular and metabolic diseases, neurological disorders and cancer; including pharmacology and toxicology studies.
