1. A method for identifying an antibody acting as an anti-tumoral agent that depletes tumor-infiltrating regulatory T cells, comprising the steps of:
a) assaying candidate antibodies for their binding specificity to LAYN;
b) selecting antibodies having a specific binding activity to LAYN; and
c) testing the binding antibodies in a cell system comprising tumor-infiltrating regulatory T cells for their ability to induce antibody-dependent cell-mediated cytotoxicity (ADCC) on the tumor-infiltrating regulatory T cells, thereby identifying an antibody that depletes tumor-infiltrating regulatory T cells.
