WebNov 7, 2024 · Background. Platelets, as small cell fragments, are not only important coagulation-related factors, but also play a vital role in cancer metastasis [].The increased level of platelets was correlated with tumor progression, recurrence and distant metastasis in various cancer types [2, 3].The high level of platelets also has a close correlation with …
WebA previous study reported that HMGB1 induced the secretion of microparticles from various cells, especially Toll-like receptor 4 (TLR4). 32,33 Therefore, one cause of PDMP production in cancer patients might be HMGB1 because platelets express TLR4. 34 Unfortunately, this study has some limitations. First, the overall sample size is very small. WebOct 11, 2024 · The interaction of tumor cells with platelets is a prerequisite for successful hematogenous metastatic dissemination. Upon tumor cell arrival in the blood, tumor cells immediately activate platelets to form a permissive microenvironment.
WebDec 1, 2024 · Some experts have found that platelets play an important role in promoting tumor hematogenous metastasis. Platelets may be involved in many processes, such as promoting tumor cell survival, helping tumor cells escape immune surveillance, helping tumors attach to endothelial cells and penetrating capillaries for distant metastasis. WebRole of platelets in cancer metastasis Platelet activation Tumor cells that enter the blood circulation have to cope with high shear rates and the immune surveillance, e.g., the assault of natural killer cells.
