Production of VLPs with heterologous glycoproteins^a

Viral protein	Effect on VLP production when coexpressed with:
	PIV5 M and PIV5 NP	MuV M and MuV NP
PIV5 HN	+++	+
MuV HN	+++	+
PIV5 F	+++	++
MuV F	+++	+++

^a“+” denotes increase ranging from 1.4-fold to 2-fold; “++” denotes increase ranging from 3-fold to 5-fold; “+++” denotes increase greater than 5-fold.
