Figure 1. NLRP12 deficiency does not influence the development of acute allergic airway inflammation.
A) Schematic illustrating OVA mediated acute allergic airway inflammation with an alum adjuvant. B) Mice immunized with OVA/alum and challenged with OVA (OVA/OVA) demonstrated a significant increase in BALF cellularity compared to wild type and Nlrp12−/− mice immunized with OVA/alum but challenged with saline (OVA/Saline). C) Differential staining of the BALF cellularity revealed that mice immunized and challenged with OVA demonstrated a significant increase in airway leukocyte populations, which were predominately eosinophilic. D) A significant increase in local (BALF) and systemic (serum) IL-13 was observed in all OVA immunized and challenged animals regardless of genotype. OVA/Saline, n = 6; Nlrp12−/−, n = 12; wild type, n = 15. E) A significant increase in OVA specific IgE was detected in serum collected from both wild type and Nlrp12−/− mice following OVA immunization and challenge. F) Central airway resistance (Rn) and tissue damping (G) in response to methacholine (MCh) was evaluated in wild type and Nlrp12−/− mice following OVA challenge. Mock (PBS), n = 4; Wild Type, n = 8; Nlrp12−/−, n = 5.
