How does a tiny hookworm outsmart the human immune system? In this episode, we explore the physicochemical fingerprint of Necator americanus, a parasite that infects millions worldwide. Using cutting-edge techniques like atomic force microscopy (AFM) and time-of-flight secondary ion mass spectrometry (ToF-SIMS), researchers reveal how the hookworm’s sheath and cuticle surfaces play a crucial role in immune evasion and infection.

🔍 Key Topics Covered: • The unique surface properties of N. americanus at the infective L3 stage • How the hookworm’s sheath diverts immune defences, aiding reinfection • The role of nano-annuli in enhancing adhesion and survival • How surface chemistry, including heparan sulphate and phosphatidylglycerol, influences parasite migration
