GSTM1 and infection: Given that Hb co‐infection dramatically impaired expulsion of Tm but did not significantly affect canonical drivers (IL‐13) or effectors (goblet cell hyperplasia, increased crypt length, type 2 gene expression) of anti‐Tm immunity, we aimed to identify if Hb was influencing Tm′s ability to establish an infection independent of any effect Hb may exert on adaptive immunity.
