BCL6 expression can be stimulated by cytokines such as IFN-γ, IL-6, type I IFN, IL-12, and TNF-α in myeloma or TFH cells (Hideshima et al., 2010; Nakayamada et al., 2011, 2014; Choi et al., 2013; Madapura et al., 2017; Ujvari et al., 2018). This evidence concerns the gene IFNG and plasma cell myeloma.
