The advancement of Pliss' lymphosarcoma in rats was shown to be associated with disorders of platelet-mediated hemostasis presenting with either lowered or increased aggregation activity of platelets. In the latter case, a direct correlation was observed between functional activity of thrombocytes, on the one hand, and degree of tumor advancement and its metastatic activity, on the other. Extract of Scutellaria baicalensis Georgi was shown to produce a normalizing effect on platelet-mediated hemostasis whatever the pattern of alteration which points to the adaptogenic activity of the drug. This activity is thought to be responsible for the drug's antitumor and, particularly, metastasis-preventing effect.

Impaired hemostatic and immune functions of platelets after acute thrombocytopenia.

J Thromb Haemost

December 2024

Institute of Vascular Biology and Thrombosis Research, Center of Physiology and Pharmacology, Medical University of Vienna, Vienna, Austria. Electronic address:

Background: Platelets are pivotal in maintaining vascular integrity, hemostasis, and immune modulation, with newly generated, immature platelets being the most responsive in fulfilling these tasks. Therefore, the immature platelet fraction provides insights into thrombopoiesis dynamics and clinical prognostication. However, it is currently unclear how immature platelet functions change in settings of acute thrombocytopenia.

Unlabelled: Backgrounds/Objectives: Abnormal platelet functions are associated with human morbidity and mortality. Platelets have emerged as critical regulators of numerous physiological and pathological processes beyond their established roles in hemostasis and thrombosis. Maintaining physiological platelet function is essential to hemostasis and preventing platelet-associated diseases such as cardiovascular disease, cancer metastasis, immune disorders, hypertension, diabetes, sickle cell disease, inflammatory bowel disease, sepsis, rheumatoid arthritis, myeloproliferative disease, and Alzheimer's disease.

Critical role for platelet Ral GTPases in regulating venous thrombosis in mice.

J Thromb Haemost

January 2025

School of Physiology, Pharmacology & Neuroscience, University of Bristol, Bristol, United Kingdom. Electronic address:

Background: Deep vein thrombosis is a major cause of morbidity and mortality globally. While its pathophysiology is complex, increasing evidence suggests a more prominent role for platelets than previously suspected. Genetic deletion of Ral GTPases, RalA and RalB, conditionally in mouse platelets (RalAB double knockout [DKO]), results in a near complete defect in P-selectin externalization upon activation, while other platelet activation responses and arterial thrombosis are preserved.

ACKR3, an atypical chemokine receptor, has been associated with prothrombotic events and the development of cardiovascular events. We designed, synthesized, and evaluated a series of novel small molecule ACKR3 agonists. Extensive structure-activity relationship studies resulted in several promising agonists with potencies ranging from the low micromolar to nanomolar range, for example, (EC = 111 nM, = 95%) and (EC = 69 nM, = 82%) in the β-arrestin-recruitment assay.

The podoplanin-CLEC-2 interaction promotes platelet-mediated melanoma pulmonary metastasis.

BMC Cancer

April 2024

Reproductive Medicine Center, China-Japan Union Hospital, Jilin University, Changchun, China.

Background: Podoplanin (PDPN) expressed on tumour cells interacts with platelet C-type lectin-like receptor 2 (CLEC-2). This study aimed to investigate the role of the PDPN-platelet CLEC-2 interaction in melanoma pulmonary metastasis.

Methods: Murine melanoma B16-F0 cells, which have two populations that express podoplanin, were sorted by FACS with anti-podoplanin staining to obtain purified PDPN + and PDPN- B16-F0 cells.
