Special Issue Information

Dear Colleagues,

Platelets are known to play a key role in thrombosis and hemostasis. In primary hemostasis, platelets are activated and adhere to the subendothelium to form platelet plugs. Overactive platelets lead to thrombosis, which in turn leads to arterial ischemia and infarction. In addition to thrombosis and hemostasis, platelets are now known to play a major role in a number of additional functions, including development of cancers, inflammatory responses, and innate immune reactions. Platelets can respond to signals from circulating tumor cells, circulatory cells, endocrine cells, and immune cells. Activated by these signals, platelets secrete over 300 active substances, including coagulation factors, growth factors, chemokines, cytokines, microbicidal proteins, and RNA species, affecting many physiological and pathophysiological processes beyond hemostasis. As bidirectional communicators, platelets can also take up plasma contents and even cellular components, thus providing another mechanism to influence pathophysiological processes.

Recent developments in platelet biology have demonstrated the role of platelets in the pathophysiology of a variety of diseases beyond coagulation disorders, including cancer, digestive disorders, respiratory disorders, neurological disorders, dermatological disorders, autoimmune diseases, and diabetes. In the pathophysiology of these diseases, platelets are both effectors and targets, making clinical applications very promising to identify and quantify specific platelet content as new biomarkers and therapeutic targets. Specifically, platelet membrane proteins, platelet-derived microparticles, platelet non-coding RNAs, platelet releasers, and platelet post-translational modifications may be dramatically altered in many diseases and therefore may be novel therapeutic targets for a number of pathological conditions.

In this issue, we welcome manuscripts that specifically address molecular studies of platelet function or platelet content as novel biomarkers or therapeutic targets for human disease. We encourage authors to submit original articles, reviews, and short communications related to this research topic. We expect submissions related to, but not limited to, the following topics:

  • Interactions between platelet and cancer cells;
  • Platelet as new biomarkers and targets for human disease;
  • Platelet communication with the environment;
  • New treatment strategies for platelet-related diseases;
  • Proteomics, metabolomics, transcriptomics, and bioinformatics of platelet.

The treatment of chondral and osteochondral defects is challenging. These types of lesions are painful and progress to osteoarthritis over time. Tissue engineering offers tools to address this unmet medical need. The use of an autologous cartilage construct consisting of hyaline cartilage chips embedded in plasma rich in growth factors (PRGF) has been proposed as a therapeutic alternative. The purpose of this study was to dig into the potential mechanisms behind the in vitro remodelling process that might explain the clinical success of this technique and facilitate its optimisation. Chondrocyte viability and cellular behaviour over eight weeks of in vitro culture, type II collagen synthesis, the dual delivery of growth factors by hyaline cartilage and PRGF matrix, and the ultrastructure of the construct and its remodelling were characterised. The main finding of this research is that the cartilage fragments embedded in the three-dimensional PRGF scaffold contain viable chondrocytes that are able to migrate into the fibrin network, proliferate and synthesise extracellular matrix after the second week of in vitro culture. The characterization of this three-dimensional matrix is key to unravelling the molecular kinetics responsible for its efficacy. Full article

In recent years, several types of platelet concentrates have been investigated and applied in many fields, particularly in the musculoskeletal system. Platelet-rich fibrin (PRF) is an autologous biomaterial, a second-generation platelet concentrate containing platelets and growth factors in the form of fibrin membranes prepared from the blood of patients without additives. During tissue regeneration, platelet concentrates contain a higher percentage of leukocytes and a flexible fibrin net as a scaffold to improve cell migration in angiogenic, osteogenic, and antibacterial capacities during tissue regeneration. PRF enables the release of molecules over a longer period, which promotes tissue healing and regeneration. The potential of PRF to simulate the physiology and immunology of wound healing is also due to the high concentrations of released growth factors and anti-inflammatory cytokines that stimulate vessel formation, cell proliferation, and differentiation. These products have been used safely in clinical applications because of their autologous origin and minimally invasive nature. We focused on a narrative review of PRF therapy and its effects on musculoskeletal, oral, and maxillofacial surgeries and dermatology. We explored the components leading to the biological activity and the published preclinical and clinical research that supports its application in musculoskeletal therapy. The research generally supports the use of PRF as an adjuvant for various chronic muscle, cartilage, and tendon injuries. Further clinical trials are needed to prove the benefits of utilizing the potential of PRF. Full article

Over the last decade, the incidence of infective endocarditis (IE) has increased, with a change in the frequency of causative bacteria. Early evidence has substantially demonstrated the crucial role of bacterial interaction with human platelets, with no clear mechanistic characterization in the pathogenesis of IE. The pathogenesis of endocarditis is so complex and atypical that it is still unclear how and why certain bacterial species will induce the formation of vegetation. In this review, we will analyze the key role of platelets in the physiopathology of endocarditis and in the formation of vegetation, depending on the bacterial species. We provide a comprehensive outline of the involvement of platelets in the host immune response, investigate the latest developments in platelet therapy, and discuss prospective research avenues for solving the mechanistic enigma of bacteria–platelet interaction for preventive and curative medicine.
