TABLE 2.

Production of VLPs with heterologous NP proteins^a

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

^a“−” denotes increase smaller than 1.4-fold; “+” 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. NiV, Nipah virus.
