• The isolate, basically the dendritic cells, is incubated with a fusion protein, named PA2024, consisting of a PAP region (the antigen of prostatic acid phosphatase, found in more than 95% of the prostate cancer cells) and a stimulating region (granulocyte-macrophage colony stimulating factor GM-CSF), which helps the dendritic cells (APCs) mature;. Here, CSF2 is linked to prostate carcinoma.
