CCL11 and Allergy: The results showed that all Streptococcus salivarius isolates (whereas Staphylococcus epidermidis isolates had no such effect) could stimulate the expression of pro-inflammatory cytokines (IL-6, IL-8, TNF-α), epithelial cytokines (IL-33 and TSLP, which can trigger type 2 immune cell-mediated allergic cascades), and the chemokine eotaxin-1 (CCL11)—an eosinophil-specific chemoattractant (eosinophils possess allergy-related characteristics).
