this binding releases an intra-cytoplasmic signal which governs the following stages , i.e . actual ingestion ( phagocytosis ) , then enzymatic destruction within phagolysosomes `` '' bactericidosis `` '' . the phase of recognition and membrane binding to bacteria thus occupies an important place in the physiological role of macrophages . two receptors are especially involved : the fc receptor and the c3b receptor .
