Platelet signal transduction, metabolism and programmed cell death

Despite being the smallest cells of human organism, platelets have incredibly complex intracellular machinery. Their cytoplasm contains dense tubular system, mitochondria, various granules, glycogen, actin-myosin system, and powerful cytoskeleton capable of lightning-quick rearrangement. Dozens of receptors on their surface detect various chemical and physical signals and transduce them into the cell. Then an immensely huge network of signal transduction decideswhether and how to get activated, or probably to go into one of the programmed cell death routes. We try to understand how all this works.
