Immunofluorescence (IF) on ethanol-fixed neutrophils is used to detect ANCA, although formalin-fixed neutrophils may be used to help differentiate ANCA patterns. ANCA can be divided into four patterns when visualised by IF; cytoplasmic ANCA (c-ANCA), C-ANCA (atypical), perinuclear ANCA (p-ANCA) and atypical ANCA (a-ANCA), also known as x-ANCA. c-ANCA shows cytoplasmic granular fluorescence ...
This pattern results from binding of ANCAs to antigen targets throughout the neutrophil cytoplasm, the most common protein target being proteinase 3 (PR3). For example, PR3 is the most common antigen target of ANCA in patients with granulomatosis with polyangiitis. In active granulomatosis with polyangiitis, c-ANCA is found over 90% of the time.

p-ANCA, or MPO-ANCA, or perinuclear anti-neutrophil cytoplasmic antibodies, are antibodies that stain the material around the nucleus of a neutrophil. They are a special class of anti-neutrophil cytoplasmic antibodies. This pattern occurs because the vast majority of the antigens targeted by ANCAs are highly cationic (positively charged) at pH ...
Neutrophils have also been demonstrated to be released into the blood from a splenic reserve following myocardial infarction. [25] The distribution ratio of neutrophils in bone marrow, blood and connective tissue is 28:1:25. [citation needed] Neutrophils are much more numerous than the longer-lived monocyte/macrophage phagocytes.
Primary autoimmune neutropenia, another name for autoimmune neutropenia, is an autoimmune disease first reported in 1975 that primarily occurs in infancy. [2] In autoimmune neutropenia, the immune system produces autoantibodies directed against the neutrophilic protein antigens in white blood cells known as granulocytic neutrophils ...

Its exact role in the function of the neutrophil is unknown, but, in human neutrophils, proteinase 3 contributes to the proteolytic generation of antimicrobial peptides. It is also the target of anti-neutrophil cytoplasmic antibodies (ANCAs) of the c-ANCA ( cytoplasmic subtype) class, a type of antibody frequently found in the disease ...
