MPPE1 and infection: hMPV infection leads to an increase in the amounts of pDCs and cDCs in the lungs, reaching their peak at 8 and 10 d.p.i., respectively, and cDCs are found more abundantly and persist until 18 d.p.i. However, the CD103+ cDC1 subset decreases during the first weeks after the infection, but 8 weeks after the infection it reaches its normal amount [88].
