Figure Legend Snippet: Omicron S1 shows reduced immune cells recruitment and expansion compared with the ancestral variant. Recombinant S1WT, S1 Omicron or vehicle (-) were injected in the hindbrain ventricle (HBV) of Tg(lyz:DsRED) (A) , Tg(mfap4:Tomato) (B) , Tg(nfkb:eGFP) (C) of 2-dpf larvae. Neutrophil (A) and macrophage (B) recruitment and number and Nfkb reporter activity (C) were analyzed at 6, 12, and/or 24 hpi by fluorescence microscopy. Representative photos for each treatment are shown from 24 hpi. Scale bar 500 μm. Each dot represents one individual, and the means ± SEM for each group is also shown. P values were calculated using one-way analysis of variance (ANOVA) and Tukey multiple range test. ns, not significant; * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001 and **** p < 0.0001. auf, arbitrary units of fluorescence.
Techniques Used: Variant Assay, Recombinant, Injection, Activity Assay, Fluorescence, Microscopy
Figure Legend Snippet: Omicron is more proinflammatory than the ancestral variant. Recombinant S1WT, S1 Omicron or vehicle (-) were injected in the hindbrain ventricle (HBV) of WT (A–F) 2-dpf larvae. The transcript levels of the indicated genes (A–E) were analyzed at 12 hpi by RT-qPCR in larval head and rest of the body and caspase-1 activity was determined at 24 hpi using a fluorogenic substrate (F) . Graphs shown are representative of three independent experiments; technical replicates are displayed in each graph. The means ± SEM for each group is shown. P values were calculated using one-way analysis of variance (ANOVA) and Tukey multiple range test. n=45 in (A–E) , n=35 in (F) . ns, not significant; * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001 and **** p < 0.0001. auf, arbitrary units of fluorescence.
Techniques Used: Variant Assay, Recombinant, Injection, Quantitative RT-PCR, Activity Assay, Fluorescence
Figure Legend Snippet: Omicron causes higher neutrophil cell death than the ancestral variant. Recombinant S1WT, S1 Omicron or vehicle (-) were injected in the hindbrain ventricle (HBV) of Tg(lyz:DsRED) (A, B) of 2-dpf larvae. Tunel positive neutrophil number (double positive) was counted at 6 hpi in the head and tail of the larvae (A, B) . Representative photos for each treatment are shown. Scale bar 500 μm. Each dot represents one individual, and the means ± SEM for each group is also shown. P values were calculated using one-way analysis of variance (ANOVA) and Tukey multiple range test. ns, not significant; * P ≤ 0.05, ** P ≤ 0.01 and **** p < 0.0001.
Techniques Used: Variant Assay, Recombinant, Injection, TUNEL Assay
Figure Legend Snippet: Trimeric ancestral variant induces a weaker immune response than its monomeric form. Recombinant S1WT (monomeric), S1/S2WT-T (trimeric) or vehicle (-) were injected in the hindbrain ventricle (HBV) of Tg(lyz:DsRED) (A) , Tg(mfap4:Tomato) (B) , Tg( nfkb :eGFP) (C) 2-day postfertilization larvae (dpf). Neutrophil (A) and macrophage (B) recruitment and number and Nfkb reporter activity (C) were analyzed at 6, 12, and/or 24 hpi by fluorescence microscopy. Representative photos for each treatment are shown from 24 hpi. Scale bar 500 μm. Each dot represents one individual, and the means ± SEM for each group is also shown.

Recombinant S1WT, S1/S2WT-T or vehicle (-) were injected in the hindbrain ventricle (HBV) of WT (A–E) 2-day postfertilization larvae (dpf). The transcript levels of the indicated genes (A–D) were analyzed at 12 hpi by RT-qPCR in larval head and rest of the body and caspase-1 activity was determined at 24 hpi using a fluorogenic substrate (E) . Graphs shown are representative of three independent experiments; technical replicates are displayed in each graph. The means ± SEM for each group is shown. P values were calculated using one-way analysis of variance (ANOVA) and Tukey multiple range test. n=40 in A-D, n=35 in E. ns, not significant; * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001 and **** p < 0.0001. auf, arbitrary units of fluorescence.
