Exploring the platelet and cancer cell interaction in metastasis targeting

Platelets are small anucleated cell fragments that ensure the stopping of bleeding. In blood metastasis of cancer, Platelets are essential. One of the most important aspects of cancer metastasis is the interaction between platelets and circulating tumor cells. Platelets are involved in cancer spread and constitute a hazardous collation with the cancer cells. There are various factors involved in hemostasis and thrombosis, which can be activated by several cancer-related stimuli, including extracellular matrix (ECM), adenosine diphosphate (ADP), and Toll-like receptors (TLRs). Furthermore, it has been previously published that platelets build up inside the main tumors, producing growth factors that encourage tumor growth and angiogenesis. Additionally, tumor cells can interact with platelets through aggregation, further protecting cancer cells. Platelets interact both functionally and physically with different types of tumor cells via integrin and other surface receptors. Platelet integrin’s primary function is to maintain platelet adhesion and aggregation at vascular damage sites. Pharmacological treatments that target integrin have been shown to effectively inhibit experimental metastasis. This review paper summarized the recent advances and progress of mechanisms in platelet activation and its interaction with cancer cells in metastasis.
