Figure Lengend Snippet: (A) Left: WT mice were administered PBS, CpG or Pm3 intrapharyngeally (i.ph.). Lungs were collected at seven days post treatment and homogenates were assayed for mouse ACE2 by ELISA. Right: K18-hACE2 Tg mice were administered PBS, CpG or Pm3 i.ph., lungs were collected at 10 days post-treatment and homogenates were assayed for human ACE2 by ELISA, n= 3 – 8, data combined from 1 – 2 independent experiments. (B) Trem2 −/− or (C) Ccr2 −/− mice were given either PBS or 10μg CpG i.ph. seven days prior to being i.n. infected with 3.5×10 4 TCID 50 SCV2 (B.1.351), mice were euthanized 3 days later. Viral loads in lung are shown as measured by TCID 50 on Vero E6 cells, n= 3 – 8, data combined from 1 – 2 independent experiments. Geometric mean, significance determined by two-tailed Mann Whitney test, LD= limit of detection, n.s.= not significant.
Article Snippet: Mouse and human ACE2 protein levels were quantified from lung homogenates by ELISA (R&D Systems #DY3437, #DY933).
