دیاپدز گلبول های سفید از جدار رگ🛡️ Once neutrophils reach the site of infection, the battle begins.Phagocytosis occurs in three steps:1️⃣ Recognition & Opsonization (IgG, C3b)2️⃣ Engulfment (Phagosome formation)3️⃣ Killing & Degradation (ROS, Myeloperoxidase, lysosomal enzymes)Neutrophils can also release Neutrophil Extracellular Traps (NETs) to immobilize and destroy pathogens.@arshadphdimeni🎯 Exam Pearls✔ Major opsonins: IgG, C3b.✔ Respiratory burst generates reactive oxygen species.✔ Myeloperoxidase converts H₂O₂ into hypochlorous acid (HOCl).✔ NETosis is an additional extracellular antimicrobial mechanism.🧠 One-LinerNeutrophils eliminate microbes through phagocytosis, oxidative killing, lysosomal enzymes, and NET formation.#Pathology #Phagocytosis #Neutrophils@arshadphdimeni
