Abstract
Platelets are important players in hemostasis. Alterations in platelet number and/or function lead to life-threatening conditions like thrombosis, myocardial infarction and stroke. During aging, changes at the cellular, organ and systemic level occur that affect platelet counts, platelet functionality, the expression of platelet surface receptors, clearance markers as well as their interactions with immune cells. Understanding how these changes influence platelets can help to prevent the alterations of hemostasis and thrombosis we observe in the elderly. In this review, we highlight the respective changes at important sites of the platelet life cycle: bone marrow, liver and spleen, but also show how alterations in immunity contribute. We point out the necessity for further research on age-related systemic alterations in these systems and their interplay with platelets to better understand the complex processes that cause alterations in the platelet life cycle during aging.
期刊介绍：
Platelets is an international, peer-reviewed journal covering all aspects of platelet- and megakaryocyte-related research.
Platelets provides the opportunity for contributors and readers across scientific disciplines to engage with new information about blood platelets. The journal’s Methods section aims to improve standardization between laboratories and to help researchers replicate difficult methods.
Research areas include:
Platelet function
Biochemistry
Signal transduction
Pharmacology and therapeutics
Interaction with other cells in the blood vessel wall
The contribution of platelets and platelet-derived products to health and disease
The journal publishes original articles, fast-track articles, review articles, systematic reviews, methods papers, short communications, case reports, opinion articles, commentaries, gene of the issue, and letters to the editor.
Platelets operates a single-blind peer review policy. Authors can choose to publish gold open access in this journal.
