Vaccinations with tumor cells engineered to produce IL-4 prolonged survival and cured 30% of mice bearing pulmonary metastases, an effect abrogated by in vivo depletion of T cells. Vaccination induced type 2 T cell polarization in both CD4 and CD8 T lymphocyte subsets. We focused on the antitumor activity exerted by type 2 CD8+ T cells (Tc2) activated by(More)
We have compared the therapeutic activity and characterized the antitumor response induced by IL-12 and IL-2 gene-transduced tumor cell vaccines. Mice bearing lung metastases of the BALB/c colon carcinoma C51 were treated with syngenic, histologically related, and antigenically cross-reacting irradiated IL-12 (C26/IL12) or IL-2 (C26/IL2) gene-transduced C26(More)
We analyzed the ability of interferon (IFN)-␥ knockout mice (GKO) to reject a colon carci-noma transduced with interleukin (IL)-12 genes (C26/IL-12). Although the absence of IFN-␥ impaired the early response and reduced the time to tumor onset in GKO mice, the overall tumor take rate was similar to that of BALB/c mice. In GKO mice, C26/IL-12 tumors had a(More)
We evaluated whether antibody response correlates with tumor therapy by cytokine gene-modified tumor cell vaccines. To characterize the antibody (Ab) response against a known antigen, colon carcinoma C26 cells and C26 variants engineered to produce interleukin (IL) 12 or IL-4 were further transduced to express the human tumor-associated antigen gp38 folate(More)
We analyzed the ability of interferon (IFN)-gamma knockout mice (GKO) to reject a colon carcinoma transduced with interleukin (IL)-12 genes (C26/IL-12). Although the absence of IFN-gamma impaired the early response and reduced the time to tumor onset in GKO mice, the overall tumor take rate was similar to that of BALB/c mice. In GKO mice, C26/IL-12 tumors(More)
The colon adenocarcinoma C26, carrying two endogenous tumor-associated antigens (TAA) recognized by CTL, has been transduced with the gene coding for the human folate receptor alpha (FR alpha) as an additional antigen in order to study the efficacy of vaccination against a tumor expressing multiple antigens. A dicistronic vector was used to transduce the(More)
BACKGROUND Aflibercept (ziv-aflibercept) is an anti-angiogenic agent recently approved in combination with FOLFIRI for the treatment of metastatic colorectal cancer (mCRC) patients previously treated with oxaliplatin. Despite heterogeneity in response to aflibercept, no biomarkers for efficacy or adverse effects have been identified. Here we present(More)
The authors report a case of Silver-Russel syndrome with severe deficit growth observed since intrauterine life. They describe the major features, that are constant and the minor features, that are variable and numerous. The features not always are present at birth. The A. exclude in this case a genetic cause and suggest a possible motherly cause.
