The ELANE gene provides instructions for making a protein called neutrophil elastase. This protein is found in neutrophils, a type of white blood cell that plays a role in inflammation and in fighting infection. When the body starts an immune response to fight an infection, neutrophils release neutrophil elastase. This protein then modifies the function of certain cells and proteins to fight the infection.

The immune system
The first line of defence is your body's skin and mucous membranes. If pathogens manage to get through these barriers, they encounter special white blood cells present in your bloodstream. There are different types of white cells, called neutrophils (polymorphs), lymphocytes, eosinophils, monocytes, and basophils. White blood cells travel in your.
