Then in AAD we identified inductive roles for: TLR2 in IL-5 release from MLN T cells, IL-5 and IL-13 release from splenocytes and AHR; TLR4 in eosinophil infiltration into BALF and blood (partial) and AHR, and; MyD88 in blood eosinophilia, IL-13 release from MLN T cells and AHR (Fig 7). Here, TLR4 is linked to Increased total eosinophil count.
