Molecular genetic aspects of human platelet antigen systems
Abstract:
Recent advances in molecular and cellular biology have made it possible to build upon previous serological and biochemical studies of human platelet alloantigen systems in important and exciting ways. In addition to providing a detailed basic understanding of the polymorphisms that are responsible for eliciting an alloimmune response, the molecular characterization of platelet membrane glycoprotein polymorphisms is expected to have an increasingly large clinical impact. As the molecular basis of the remaining platelet antigen systems becomes known, our ability to design novel diagnostic and therapeutic approaches for the care and management of patients with PTP and NATP should improve.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
