The effect of Lyprinol was evaluated on LTB4-induced human monocytes (normal and allergic donors) activation. Peripheral blood normal monocyte-derived monocytes when stimulated by Interleukin-4 (IL-4) produced high amounts of leukotriene B4 (LTB4) through the activation of the 5-lipoxygenase pathway. Maximal
