TNFSF14 and tuberculosis: Cells from both species produced very high levels of transcripts for genes such as IL2, IL21, IL26, IFNG, TNF, CCL3, CCL4, CD40LG, CSF2, and GZMB, as well as several molecules less well understood in TB T cell immunology including: CCL20, SEMA7A, TNFSF14, FASLG, CTSB, TG, and SLAMF1 (Figure 4L).
