Imary N. brasiliensis infection.Intestinal goblet cell hyperplasia was assessed by determining the total number of Sudan I PAS-positive goblet cells per 5 villi in histological sections of the small intestine at day 7 and 10 PI (C). Total IgE production in the serum was measured by ELISA at day 7 and 10 PI (D). The data are representative of the results of two ML-281 chemical information independent experiments with mean values+SEM and n = 4 or 5 mice per group. ND, not detected, ns = not significant. One-WayANOVA, *P,.05, **P,.01. (TIF)Figure 1676428 S3 N. brasiliensis infection is comparable between BALB/c and IL-4Ra2/lox mice. Five mice per group were infected with 750 N. brasiliensis L3 larvae. Faeces were collected from day 5 to 10 post infection (PI) and egg production was calculated using the modified McMaster technique (A). At days 7 and 10 PI the worm burden in the small intestine was assessed (B). Intestinal goblet cell hyperplasia was assessed by determining the total number of PAS-positive 15481974 goblet cells per 5 villi in histological sections of the small intestine at day 7 and 10 PI (C). Total IgE production in the serum was measured by ELISA at day 7 and 10 PI (D). Comparison of the response of infected BALB/c and IL-4Ra2/lox mice to acetylcholine is also shown for day 7 p.i. The data represents one (A-D) and two (E) independent experiment with n = 5 per group and mean values + SEM. ND, not detected. Unpaired two-tailed Student t test, ns = not significant.

Duplicated worm burdens from figure 1B represented as individual counts at days 7 and 10 PI. As above, the data represents three independent experiments combined, with n = 4 or 5 per group, ns = not significant. OneWay-ANOVA, ***P,.001.

Table S1 summarizes the surface expression of IL-4Ra on T cell subpopulations determined by FACS as previously described [29,30]. Subpopulations include CD4+, CD8+, cd T cells and NK T cells.

Caenorhabditis elegans is an extremely versatile and appropriate animal model for mimicking and recapitulating in vivo the key molecular mechanisms underlying the gene-and tissue-specific protein misfolding and toxicity related to the human pathogenesis [1]. Despite the evolutionary distance from vertebrates, human proteins substantially maintain their structure and function when they are expressed in C. elegans [1]. Many variant proteins associated to human diseases cause a pathological phenotype in worms and this c.Imary N. brasiliensis infection.Intestinal goblet cell hyperplasia was assessed by determining the total number of PAS-positive goblet cells per 5 villi in histological sections of the small intestine at day 7 and 10 PI (C).
