Well, it basically recruits special types of immune cells, white blood cells. So we have macrophages as well as the three different types of granulocytes. So we have neutrophils, we have Basophils, which we spoke about already and we have these eosinophils. Now these eosinophils are granulocytes that are specialized to fight certain parasites. So if the pathogen is parasitic then it's these cells that will ultimately end up fighting those parasites. Now neutrophils are basically a type of phagocytic cell.
