NRG4 and tuberculosis: The interaction from myofibers to other myogenic cells via NRG4 and ERBB4, FAPs to myeloid cells via BMP5 and BMPR1A/2 and lymphoid cells to MuSCs via EGF and EGFR was only observed in Duroc pig; MuSCs provided BTC to EGFR in myofibers that existed in TB rather than in Duroc pig (Figures 2C and S4C).
