Resting CD4 regulatory T cell and neuroblastoma: A Mendelian randomization study

Abstract

Neuroblastoma (NB) is a common extracranial solid tumor in children, and currently our understanding of the molecular mechanisms underlying tumor progression is not very thorough. In clinical practice, although the prognosis and survival rates of NB patients in the low‐risk and medium‐risk groups are still acceptable, the prognosis and survival rates of NB patients in the high‐risk group are extremely poor. Therefore, improving awareness of NB tumors is crucial for improving the treatment status of NB patients in clinical practice. So we collected common tumor exposure factors and performed multiple Mendelian randomization (MR) analysis on NB, and ultimately determined that the increase in Resting CD4 regulatory T cell was positively correlated with the occurrence and development of NB. In addition, we also used the network pharmacology algorithm proximity to screen the NB chemotherapy drug papain and reasonably speculated that there is an interaction between papain and CD4 regulatory T cell in the chemotherapy of NB patients.
