Wissenschaftler identifizieren synthetische Mini-Antikörper zur Bekämpfung von COVID-19

Durch ein Screening von hunderten synthetischen Mini-Antikörpern, sogenannten Sybodies, identifizierten Wissenschaftlern einen solchen Mini-Antikörper, der SARS-CoV-2 daran hindern könnte, menschliche Zellen zu infizieren

Lama-Mini-Antikörper und ihre synthetischen Imitationen

Die Fähigkeit von SARS-CoV-2, Zellen zu infizieren, hängt von den Wechselwirkungen zwischen dem viralen Spike-Protein und dem menschlichen Zelloberflächenprotein ACE2 ab. Damit sich das Virus an der Zelloberfläche festhaken kann, bindet das Spike-Protein ACE2 über drei fingerartige Vorsprünge, die so genannten Rezeptorbindungsdomänen (RBDs). Die Blockierung der RBDs hat daher das Potenzial, das Eindringen des Virus in menschliche Zellen zu verhindern. Dies kann mit Hilfe von Antikörpern erreicht werden.

Nanokörper, kleine Antikörper, die in Kamelen und Lamas gefunden werden, sind aufgrund ihrer hohen Stabilität und ihrer geringen Größe vielversprechende Werkzeuge gegen Viren.
