TY - JOUR T1 - PLatelet inhibition and cancer promotion AU - Goldstein MR, Mascitelli L, Pezzetta F Y1 - 2010/11/22 N1 - 10.1001/archinternmed.2010.420 JO - Archives of Internal Medicine SP - 1943 EP - 1944 VL - 170 IS - 21 N2 - It has been shown in rodents that the platelet inhibitor, clopidogrel, increases the regulatory T-cell (Treg) pool and also increases splenic-derived endothelial progenitor cells.3 An increase in Tregs might impair host antitumor immune responses; indeed, Treg numbers in many solid tumors have correlated inversely with patient survival.4 In addition, it has become evident that endothelial progenitor cells promote tumor angiogenesis and are found more frequently in the peripheral blood and tumors of patients with more invasive disease.5 SN - 0003-9926 M3 - doi: 10.1001/archinternmed.2010.420 UR - http://dx.doi.org/10.1001/archinternmed.2010.420 ER -
