As NHL is a multifactorial disease, we wanted to know whether the expression of genes involved in DLBCL and FL suggested by Flowers et al. was involved in cases of C. burnetii associated NHL (EXOC2, MYC, NCOA1, PTV1, CXCR5, ETS1, LPP and BCL2) [1]. The gene discussed is CXCR5; the disease is non-Hodgkin lymphoma.
