Immune Responses to Biosurfaces


Book Description

​The collection of chapters in this proceedings volume brings together research from academic and industry scientists and clinical development experts who are focused on contemporary and emerging aspects of improving treatments employing biosurfaces. Interactions between biomaterial implants, devices, cell therapies, and whole organ transplants frequently trigger activation of body defense systems and responses that negatively affect the clinical outcome. Optimal tissue integration and modulation of foreign body reactions is therefore essential for preserving anticipated functions and avoiding adverse effects. Topics covered include mechanistic and applied research within the fields of extracorporeal devices, soft and hard tissue implants, tissue and biomaterial-targeting, therapeutic modulation of foreign body reactions, cell encapsulations, as well as cell and whole organ transplantation.

Current Research in Pulsed Laser Deposition


Book Description

Despite its limitation in terms of surface covered area, the PLD technique still gathers interest among researchers by offering endless possibilities for tuning thin film composition and enhancing their properties of interest due to: (i) the easiness of a stoichiometric transfer even for very complex target materials, (ii) high adherence of the deposited structures to the substrate, (iii) controlled degree of phase, crystallinity, and thickness of deposited coatings, (iv) versatility of the experimental set-up which allows for simultaneous ablation of multiple targets resulting in combinatorial maps or consecutive ablation of multiple targets producing multi-layered structures, and (v) adjustment of the number of laser pulses, resulting in either a spread of nanoparticles, islands of materials or a complete covering of a surface. Moreover, a variation of PLD, known as Matrix Assisted Pulsed Laser Evaporation, allows for deposition of organic materials, ranging from polymers to proteins and even living cells, otherwise difficult to transfer unaltered in the form of thin films by other techniques. Furthermore, the use of laser light as transfer agent ensures purity of films and pulse-to-pulse deposition allows for an unprecedented control of film thickness at the nm level. This Special Issue is a collection of state-of-the art research papers and reviews in which the topics of interest are devoted to thin film synthesis by PLD and MAPLE, for numerous research and industry field applications, such as bio-active coatings for medical implants and hard, protective coatings for cutting and drilling tools withstanding high friction and elevated temperatures, sensors, solar cells, lithography, magnetic devices, energy-storage and conversion devices, controlled drug delivery and in situ microstructuring for boosting of surface properties.

The future direction toward immunological issues of allo-and xeno-islet transplantation


Book Description

Islet transplantation can effectively control the blood glucose of fragile type 1 diabetes patients, thus significantly reducing hyperglycemia and improving HbA1c, and has become one of the ideal options for the treatment of type 1 diabetes patients. However, despite great progress, current islet transplantation is still limited by the isolation process, the culture period, and the rapid decline in islet functional activity after transplantation. Long-term survival and function of islet grafts are affected by non-immune and immune-related factors. To overcome these obstacles, various strategies, including stem cell combination transplantation, have been used for islet transplantation. Stem cells can promote vascular regeneration of islets and reduce inflammation and innate immune damage in the early stage of islet transplantation through potential immunomodulatory and anti-inflammatory effects. Therefore, combined transplantation of islets and stem cells can improve the survival rate of islets. In view of this, we are very honored and pleased to have some of the leading research groups in diabetes research contribute to the topic of islet transplantation. This special issue of the current landscape is dedicated to summarizing the latest advancements in allogenic and xenogenic islet transplantation and strategies to overcome its current limitations. Diversified topics related to islet isolation, islet transplantation, stem cells, immune regulation, angiogenesis, and strategies overcoming immune responses are welcome.
