This may be due to individual tumor composition variability, small sample size, and the fact that the effect of OX40L/PPT on the growth of this type of tumors is caused by the change in activated immune cell populations, and not the proportion of these immune cell populations among all intratumoral immune cells (the individual immune cell type activation was not evaluated in this study due to the method limitations). Here, TNFSF4 is linked to neoplasm.
