Additionally, intratumoral administration of oncolytic virus (OV) armed with the chemokine RANTES as chemoattractant agent and IL-15 as a T cell growth factor, combined with anti-GD2-CAR T cells, was led to similar outcomes (i.e., local accumulation and survival of T cells) in the neuroblastoma tumor model [46]. The gene discussed is CCL5; the disease is neoplasm.
