  • He has been member of the Directive Board of the CUN, President of its Educational Board, co-Director of the Cell Therapy Area of the University of Navarra and Director of the Department of Oncology on two periods, as well as one of the founders and the first President of the Spanish Melanoma Group (Grupo Español Multidisciplinar de Melanoma, GEM) (2008-2017).

  • Using immunohistochemistry, we showed that intratumoral density of CD4/CD8+ T-cells significantly increased with BRAFi treatment. (scienceexhibitions.org)
  • Furthermore, in biopsies of progressing lesions, the density of the CD4/CD8+ T-cells reduced to levels observed in the pre-BRAF inhibitor samples. (scienceexhibitions.org)
  • Vessel density was counted within the tumors, in the tumor-surrounding stroma, and, as a control, in the normal skin of the operation specimen. (uni-wuerzburg.de)
  • Whereas, irrespective of the patients' age and location of tumors, the vessel density in normal skin showed no significant differences (8.8 ± 2.7), the counts in the peritumoral stroma revealed significant differences between the different tumors investigated. (uni-wuerzburg.de)
  • Determination of blood vessel density in the peritumoral stroma may be an additional parameter for differential diagnosis of trichogenic tumors of uncertain dignity. (uni-wuerzburg.de)
  • Knockdown of T-bet expression in Mart-127-35 -specific T-cell-receptor-engineered human CD4(+) CD25(-) and CD8(+) T cells attenuates effector function. (uchc.edu)
  • As as effector CTLs are produced shortly, they could recognize and eliminate the tumor cells [44C47]. (aboutsciencenow.info)
  • To prevent infected cell lysis, recombinant replication deficiency virus has been developed as a gene delivery tool to replace wild-type adenovirus (recombinant AdV in "application" part). (genemedi.com)
  • Once packaged into a E1-complementing cell line, which provides the E1 products in trans, such as QBI 293A Cells, recombinant viral will be easily propagated. (genemedi.com)
  • It is an APC Activator used to increase an immune response to tumors, and is administered by subcutaneous injection. (wikipedia.org)
