By Dirk Nagorsen,Francesco M. Marincola

lively particular immunotherapy is a promising yet investigational modality within the administration of melanoma sufferers. at present, a number of assorted melanoma vaccine formulations akin to peptides, proteins, antigen-pulsed dendritic cells, entire tumor cells, and so forth. together with numerous adjuvants and companies are being evaluated in medical trials (1-3). to figure out the optimum melanoma vaccine method, a surrogate immunological end-point that correlates with scientific final result has to be outlined, because it may facilitate the speedy comparability of those quite a few formulations. conventional immunological assays akin to ELISA, proliferation and cytotoxicity assays can realize immune responses in vaccinated sufferers yet are usually not quantitative. against this, novel assays equivalent to enzyme-linked immunospot (ELISPOT) assay, intracellular cytokine assay and tetramer assay can quantitate the frequency of antigen-specific T cells. of those, the ELISPOT assay has the five lowest detection restrict with 1/10 peripheral blood mononuclear cells (PBMC) and has been decided to be the most precious assays to judge immune reaction to melanoma vaccines (4). even if, the IFN-? ELISPOT assay isn't really an unique degree of cytotoxic T-lymphocyte (CTL) job as non-cytotoxic cells may also secrete IFN-?. also, CTL with lytic task don't consistently secrete IFN-? (5). A extra correct method of investigate practical job of cytotoxic lymphocytes will be to degree the secretion of molecules which are linked to lytic job. one of many significant mechanisms of cell-mediated cytotoxicity includes exocytosis of cytoplasmic granules from the effector towards the objective cell.
