Characterization of Macrophages and Osteoclasts in the Osteosarcoma Tumor Microenvironment at Diagnosis: New Perspective for Osteosarcoma Treatment?

Biological and histopathological techniques identified osteoclasts and macrophages as targets of zoledronic acid (ZA), a therapeutic agent that was detrimental for patients in the French OS2006 trial. Conventional and multiplex immunohistochemistry of microenvironmental and OS cells were performed on biopsies of 124 OS2006 patients and 17 surgical (“OSNew”) biopsies respectively. CSF-1R (common osteoclast/macrophage progenitor) and TRAP (osteoclast activity) levels in serum of 108 patients were correlated to response to chemotherapy and to prognosis. TRAP levels at surgery and at the end of the protocol were significantly lower in ZA+ than ZA− patients (padj = 0.0011; 0.0132). For ZA+-patients, an increase in the CSF-1R level between diagnosis and surgery and a high TRAP level in the serum at biopsy were associated with a better response to chemotherapy (p = 0.0091; p = 0.0251). At diagnosis, high CD163+ was associated with good prognosis, while low TRAP activity was associated with better overall survival in ZA− patients only. Multiplex immunohistochemistry demonstrated remarkable bipotent CD68+/CD163+ macrophages, homogeneously distributed throughout OS regions, aside osteoclasts (CD68+/CD163−) mostly residing in osteolytic territories and osteoid-matrix-associated CD68−/CD163+ macrophages. We demonstrate that ZA not only acts on harmful osteoclasts but also on protective macrophages, and hypothesize that the bipotent CD68+/CD163+ macrophages might present novel therapeutic targets

Un sistema internacional inestable con dominio de los Estados Unidos

Con la imposición de la agenda única de terrorismo y la invasión a Iraq ¿se consolidó Estados Unidos como potencia mundial? o con el ascenso de China y los avances constitucionales europeos podríamos avanzar hacia una nueva división del mundo sobre bases diferentes de las de la Guerra Fría. En este caso ¿dónde se situaría América Latina

L'Amérique latine face aux nouveaux aspects du problème pétrolier

Latin America and the new aspects of the oil question, by Pierre Gilhodes There are three possible oil policies open to Venezuela: give complete liberty to free enterprise, i.e. the American oil companies, eliminate the latter and assume direct responsibility for oil drilling, or take up an intermediate position and attempt to retain as much as possible of the wealth generated by oil in the country. It is the latter policy that has been pursued by the three constitutional governments in Venezuela since 1958. Today American companies are faced with the possibility that Venezuela and the other oil producing countries in Latin America may imitate certain Arab States and radicalize this reformist policy. [Revue française de science politique XXII (6), décembre 1972, pp. 1308-1328.]L'Amérique latine face aux nouveaux aspects du problème pétrolier, par Pierre Gilhodes Trois politiques pétrolières sont possibles au Venezuela : laisser libre cours à la libre entreprise c'est-à-dire aux compagnies pétrolières américaines, éliminer ces dernières et prendre en charge directement l'exploitation ou, position intermédiaire, chercher à conserver sur place le maximum de richesses engendrées par le pétrole. C'est cette dernière politique qu'ont adoptée les trois gouvernements constitutionnels vénézuéliens depuis 1958. Aujourd'hui, les compagnies américaines peuvent craindre qu'à l'instar de certains Etats du monde arabe, le Venezuela et les autres pays pétroliers d'Amérique latine ne radicalise cette politique "réformiste".
