IL4 and infection: Given that IL‐5 and c‐Kit knockouts, on the other hand, largely lacking eosinophils and mast cells respectively, do not experience increased susceptibility to HD Tm infection [131], basophils may be uniquely capable of providing key IL‐4 signals necessary for TH2 generation during HD Tm infection, but further study on TSLP‐basophil interactions is needed to determine when during infection, where in tissue, and whether TSLP interacts with basophils directly in this potential key signalling event occurs.
