Fig. 4From: Differential effects of innate immune variants of surfactant protein-A1 (SFTPA1) and SP-A2 (SFTPA2) in airway function after Klebsiella pneumoniae infection and sex differencesEffect of sex on airway function after infection and methacholine (50 mg/mL). Airway functions such as respiratory resistance (Rrs) panel a, compliance (Crs) panel b, elastance (Ers) panel c, and constant phase model parameters airway resistance (Rn), tissue damping (g), and tissue elastance (h), (panels d, e, f) were measured in SP-A1 (6A2, 6A4), SP-A2 (1A0, 1A3), SP-A1/SP-A2 (6A2/1A0, co-ex), and SP-A (KO) male and female mice after challenge with methacholine (50 mg/mL). Data are expressed as mean ± SD (4 replicates per group). *p < 0.05Back to article page
