Figure Lengend Snippet: Iba1 + (microglia/monocyte lineage), CD68 + (macrophages) and MPO + (neutrophils) cells presence in the olfactory epithelium before and during SARS-CoV-2 infection. Immunostaining on successive slides of the olfactory epithelium from a non-infected ( A ) or 1 dpi hamster ( B ). Only Iba1 + cells are present in the uninfected olfactory epithelium (OE) and in the lamina propria (LP). In the infected epithelium, Iba1 + cells are massively present in the OE while CD68 + and MPO cells are mostly present in the desquamated cells (red asterisk) in the lumen of the nasal cavity (white asterisk)

Figure Lengend Snippet: Immunosuppression induced by cyclophosphamide reduces damage of the olfactory epithelium as well as OE infection area. ( A ) Expression of innate immune genes in the nasal turbinates with or without cyclophosphamide treatment at 1 and 2 days post-infection (dpi). Iba1, CD68 and Ncf2 are related to the presence of microglia/macrophages, monocytes/macrophages and neutrophils, respectively; TNFα and IL6 are two cytokines expressed during inflammation; SARS-CoV-2 N expression is related to the SARS-CoV-2 infection. Results represent the Mean ± SEM relative to vehicle-treated hamsters ( n = 4, * p < 0.05; Mann–Whitney test). Representative images of the infected olfactory epithelium immunostained for MPO (neutrophil marker) and SARS-CoV-2 N protein in ( B ) vehicle and ( C ) cyclophosphamide treated animal (olfactory epithelium (OE), lamina propria (LP)). In the vehicle condition, the lumen (white asterisk) is filled with desquamated cells (red asterisk) containing MPO signal. In the cyclophosphamide condition, MPO signal is absent and the lumen is mostly free of cellular debris . Quantification in the OE of ( D 1 ) MPO + neutrophil presence ( D 2 ) damage score ( D 3 ) SARS-CoV-2-infected area and in the lumen of the nasal cavity of ( D 4 ) desquamated cells area and ( D 5 ) percentage of SARS-CoV-2-infected area in the desquamated cells (Mean ± SEM, n = 8 areas of the nasal cavity from 4 different animals, * p < 0.05, ** p < 0.01, *** p < 0.001 (Mann–Whitney))

doi: 10.1111/bjd.16600

Figure Lengend Snippet: (a) Perilesional and chronic lesional HS tissue sections demonstrate dermal infiltration of inflammatory cells, including macrophages in affected areas (n=15, H&E). (b) Immunohistochemistry demonstrates a CD163+ infiltrate in the dermis of in HS chronic lesional tissue (n=8, 20x, scale bar 100 μm outer panels; 10x, scale bar 250 μm middle panel), especially surrounding hair follicles (black arrowheads, 20x, scale bar 100 μm). (c) Quantification of CD163 protein expression in perilesional and lesional regions (mean ± SD, *p=0.0357, Mann-Whitney U test). (d) Flow cytometry demonstrates a 29.4% increase in CD68+C163+ cells in chronic HS lesions (n=3, pink) compared to normal control tissue (n=2, grey). Live single cells were used to set population gates followed by selecting CD68+ cells. (e) Indirect immunofluorescence for CCL18 in chronic HS lesions (n=5), normal control tissue (n=3) and perilesional tissue (n=3) (10x, scale bar 250 μm). (f) Double indirect immunofluorescence staining for CD163 (red), CCL18 (green), and DAPI for nuclei staining (blue). The images for CD163 and CCL18 were merged (yellow-gold) (n=5, 20x, scale bar 100 μm). (g) HS chronic lesional tissue (n=5) show inflammatory infiltrate (black arrow) adjacent to collagen (yellow asterisks, blue stained material) as well as near a hair follicle (black arrowhead) (10x, scale bar 250 μm, perilesional (n=5), Masson’s trichrome (MT)). (h) Picrosirius Red (PSR) staining shows more organized thick, mature, dense bundles of collagen in perilesional tissue (n=1) and thinner, less mature, loose collagen bundles in the chronic lesional HS tissue (n=2) (white arrows, 20x, scale bar 250 μm). (i) Mixed infiltrate including macrophages (black arrow) and reactive myofibroblasts (black double arrow) are present in chronic lesional tissue, 60x. (j) Schematic of proposed role for macrophages in chronic HS: CD68+CD163+ macrophage release of CCL18 stimulates fibroblast-mediated collagen deposition as seen clinically in chronic HS lesions.
