According to a study from the United States, "Recombinant human parainfluenza virus type 1 (rHPIV1) was modified to create rHPIV1-P(C-), a virus in which expression of the C proteins (C ', C, Y1, and Y2) was silenced without affecting the amino acid sequence of the P protein. Infectious rHPIV1-P(C-) was readily recovered from cDNA, indicating that the four C proteins were not essential for virus replication." "Early during infection in vitro, rHPIV1-P(C-) replicated as efficiently as wild-type (wt) HPIV1, but its titer subsequently decreased coincident with the onset of an extensive cytopathic effect not observed with wt rHPIV1. rHPIV1-P(C-) infection, but not wt rHPIV1...
