WebEosinophil secretory (specific) granules have a unique morphology and are both a morphologic hallmark of eosinophils and fundamental to eosinophil-mediated responses. Eosinophil mediators with multiple functional activities are presynthesized and stored within these granules, poised for very rapid, stimulus-induced secretion.
WebNov 1, 2005 · Secretion of interleukin‐4 (IL‐4) by leukocytes is important for varied immune responses including allergic inflammation. Within eosinophils, unlike lymphocytes, IL‐4 is stored in granules (termed specific granules) and can be rapidly released by brefeldin A (BFA)‐inhibitable mechanisms upon stimulation with eotaxin, a chemokine that activates …
