“…32 Eosinophil activation in diseases associated with fibrosis and necrosis can modulate fibroblasts activity through the release of biologically active compounds that exhibit either fibrogenic or fibrolytic activities. [32][33][34] In addition to its granule content of cationic proteins such as ECP, major basic protein, and eosinophil peroxidase with known toxic effects on various cells and tissues including bladder epithelium, 35,36 eosinophils are now known to have the capacity to express, store, and release an array of up to 18 different cytokines, chemokines, and growth factors, including interleukin-3 (IL-3), IL-4, IL-5, IL-6, regulated upon activation normal T lymphocyte expressed and secreted (RAN-TES), granulocyte-macrophage-colony stimulating factor, tumor necrosis factor-␣, and transforming growth factor-. 37 Moreover, eosinophils have been shown to express major histocompatibility class II and CD4 molecules and act as antigen presenting cells in vitro.…”
