ATCC reference strain vr2332

Experimental layout. Lungs were collected from influenza- and PRRSV-negative 8–12-week-old pigs. Mononuclear phagocytes (MNPs) from bronchoalveolar lavage (BAL) and parenchyma (PAR) were enriched using OptiPrep gradient. MNPs were infected with North Carolina (NC) PRRSV-2 strains NC134 and NC174 (MOI = 1) and control media for 12 h. Infected and control porcine alveolar macrophages (PAMs), pulmonary intravascular macrophages (PIMs), monocyte-derived dendritic cells (moDCs), and classical DCs (cDCs) were sorted, and RNA-seq was performed on each cell subset. Additional PAM and PIM sorted cells were used for qPCR and NanoString validations. For other assays, enriched MNPs were plated to allow macrophage adhesion for 2 h. PAMs and PIMs were subsequently infected with different NC PRRSV-2 strains (NC134, NC174, and NC144) or <t>VR2332</t> prototype strain; uninfected cells were used as negative control. Infected macrophages were used in different assays: mitochondrial function assay (Seahorse Agilent technology) and ROS and NO production assays. Created in BioRender.

Article Snippet: The viruses used in the study included the VR2332 NA reference strain (ATCC VR-2332) and the MN184C strain provided kindly by Drs. Kelly Lager and Kay Faaberg at U.S. Department of Agriculture-Agriculture Research Service (USDA-ARS).

Techniques:

Phylogenetic analysis of the GP5 Amino acid sequence of the two Mosaic sequences, MN184C and VR2332. The analysis was done via the neighbor-joining method using MEGA7.0.

Vaccination-induced humoral and cellular responses. ( A ) The virus neutralization was expressed as viral copy numbers (log10 scale), as measured by RT-qPCR in cell supernatants after the infection of MARC-145 cells with pre-incubated serum–virus mixtures. ( B ) The expression of IFN-γ mRNA as fold changes, by either VR2332 or MN184C-stimulated PBMCs collected on the challenge day. Each dot represents the value of one animal. The variation is expressed as standard error of the means. There were three independent replications. Significant differences were calculated by a two-way ANOVA or Student’s t test (* p < 0.05, *** p < 0.0001).
