title: Platelet clinical proteomics: Facts, challenges, and future perspectives.
abstract: In recent years, proteomics has been applied to platelet clinical research. Platelets are small enucleated cells that play a fundamental role in hemostasis. In a pathological context, unwanted platelet activation is related to various diseases, primarily thrombosis, but also cancer metastasis, inflammation, immunity, and neurodegenerative diseases. The absence of a nucleus is one of the reasons why proteomics can be considered an ideal analytical tool for platelet research. Indeed, platelet proteomics has allowed the identification of many novel signaling proteins and receptors, several of which are being pursued as potential therapeutic targets. Encouraged by this success, several research groups have recently initiated clinical proteomics studies covering diseases where platelets are involved in some way, such as coronary artery disease, storage pool diseases, uremia, cystic fibrosis, and Alzheimer disease. The goal was to identify platelet biomarkers and drug targets that can help to improve the treatment/diagnosis of the disease and provide further mechanistic evidences of the role platelets play in the pathology. The present article will comment on the recent progress of clinical proteomics in the context of platelet research, challenges, and perspectives for the future ahead.
