Figure Lengend Snippet: To characterize macrophage polarization, adipose tissue sections were doubly stained for (A) CD86 and CD68 (M1) and (B) CD163 and CD68 (M2). (C) UCP1 was present in CD163+ cells in SC WAT. Yellow arrows point to UCP1+CD163+DAPI+ cells (scale bar: 50 μm). (D) UCP1+CD163+ cells were quantified in SC WAT before and after mirabegron treatment. Data indicate the mean ± SEM (n = 13). *P < 0.05 and ***P < 0.001, by paired, 2-tailed Student’s t test.

D Robust rank aggregation scores (RRA) scores for gene knockouts enriched in surviving MA-104 cells compared to pre-infection; top 10 hits for each screen are shown as colored datapoints. E RRA scores of SHFV vs. PRRSV-2, with CD163 , FCGRT (FcRn), and B2M circled and labeled. F Infection of cells transduced with single-guide RNA targeting grivet (for MA-104) or human (for ACHN) FCGRT (ΔFcRn), or empty vector control. Viruses tested on these cells are arranged in terms of relatedness to arteriviruses from left to right, with taxonomic relationships shown along the top. Data are presented as mean values ± SEM. Infections were performed with n = 3 biological replicates at an MOI of 0.01. Supernatant was titrated via plaque assay or focus-forming assay at the indicated time points; asterisks represent p-values (**p ≤ 0.01; *** p ≤ 0.001) derived from a two-tailed unpaired t-test with Welch correction and multiple comparisons testing.

Article Title: The neonatal Fc receptor (FcRn) is a pan-arterivirus receptor

doi: 10.1038/s41467-024-51142-x

Figure Lengend Snippet: A Western blot showing gCD163 and gFcRn expression in wild-type (WT) MA-104 cells and MA-104 cells with ectopic expression of gCD163, gFcRn, or both. B Cells from A were infected with SHFV (MOI = 30) and assayed for intracellular SHFV RNA 4 h later using single molecule RNA fluorescence in situ hybridization (smRNA FISH). Confocal microscopy (×600 magnification) was used to capture 16–18 fields of view taken at random (one representative shown). Blue = nuclei; red = smFISH detecting viral (v)RNA, Scale bar = 25 μm. C Quantification of microscopy performed in B . From each field of view, the percent vRNA positive cells, average number of puncta per infected cell, and average puncta FISH intensity per infected cell were determined and graphed as independent points. Error bars represent the mean ± SEM. Data shows results from one experiment. D Time course of SHFV production from wild-type (WT) MA-104 cells (red) compared to dual-overexpressing gCD163/gFcRn cells (black) at a low (0.03, left) and high (3, right) MOI, n = 3 biological replicates. E Cytopathic effect of SHFV infection of wild-type (WT) MA-104 cells (red) compared to dual-overexpressing gCD163/gFcRn cells (black) at a low MOI (0.03) 24 hrs after inoculation. Data shows results from one representative experiment in D . F Photographs of plaque assay wells (6-well plate) fixed and stained with crystal violet 2 days after inoculation. Note the larger and more well-circumscribed plaques in the CD163/FcRn-dual-expressing cells.

Figure Lengend Snippet: A FcRn orthologs from natural and potential arterivirus hosts—grivet (g), human (hu), mouse (m), pig (p), and horse (ho)–were introduced into MA-104ΔFcRn cells and inoculated with SHFV (red), PRRSV-2 (green), or EAV (blue) at an MOI of 0.01, n = 2 biological replicates. FcRn orthologs derived from the natural host of an arterivirus (i.e., positive control) are denoted by a black outline. Productive infection was then assessed via plaque assay of supernatant at 2 days post inoculation. B Similar experimental setup to A , except with CD163 orthologs in MA-104ΔCD163 cells.
