Moreover, primary immunodeficiency (Yazdani et al., 2017), chemokine signaling pathway (Meng, Xue, & Chen, 2018; Zhou, Cao, Li, & Zhao, 2018), steroid hormone biosynthesis (Boibessot & Toren, 2018; Hima & Sreeja, 2016), and intestinal immune network for IgA production (Liang et al., 2018) all participate in tumor progression and regulation of the tumor microenvironment. The gene discussed is CD79A; the disease is neoplasm.
