In addition, eosinophils can help keep the immune system balanced. They help control the response to foreign antigens (structures that antibodies bind to). These include food and microorganisms (harmful and beneficial, e.g. microbiota ). Eosinophils also help prevent immune cells from attacking the body ’s own tissues [ 2, 16, 17 ].
What causes eosinophils to drop?
1) Infections. When there is an acute infection, several substances are secreted to attract eosinophils from blood to affected tissues. This causes blood eosinophil levels to drop rapidly. A complete absence of eosinophils is also seen in serious infections such as sepsis [ 20, 21 ].
