The role of melatonin in modulating parasite infections

Abstract

In giardiasis, serum melatonin levels are elevated in these patients; this suggests a positive correlation between the level of melatonin and phagocytic activity in infected patients, possibly related to melatonin’s immunomodulatory effect [2]. The study in vitro showed que phagocytes exhibited higher rates of Giardia lamblia elimination when treated with melatonin. In the group of older mothers, colostrum MN phagocytes treated with melatonina obtained a higher microbicidal index for G. lamblia [6].
