Recent studies have suggested that uptake of bacteria by human platelets is more similar to ingestion of the same organisms by neutrophils than previously considered. Platelet pseudopods surround a bacterium by a process of circumferential adherence until the organism is fully enclosed in a vacuole consisting of internalized extracellular space surrounded by plasma membrane. The surface connected, open canalicular system (OCS) is not involved in the process of platelet phagocytosis. The present… CONTINUE READING
