A nanobody discovery pipeline incorporating competition-based yeast surface display assays is optimized to isolate single-chain variable heavy chain-only antibody domains (VHHs or nanobodies) that bind human ACE2 and inhibit SARS-CoV-2 entry, showcasing their potential as broadly acting receptor-targeted biologics against pandemic-threat viruses.
It is demonstrated that nanobodies targeting the PLpro/ISG15 interface can achieve synergistic antiviral and immunomodulatory effects, providing a proof-of-concept for a novel therapeutic approach to combat SARS-CoV-2 and potentially other emerging coronaviruses.

HRBD demonstrated potent and broad-spectrum inhibition against Pangolin-CoV, SARS-CoV, SARS-CoV, SARS-CoV-2, and its variants, lowering the half-maximal inhibitory concentration (IC50) by approximately 1000-fold compared to the monomeric RBD.

The rapid evolution of SARS-CoV-2 and the ongoing risk of zoonotic spillover highlight the need for vaccines that provide broad protection beyond strain-specific immunity. Here, we present a structure-guided, AI-enabled strategy for rational antigen design that enhances cross-reactive B-cell epitope recognition across...

ABSTRACT The continuous emergence of variants of concern (VoCs) represents a significant challenge to effectively control severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although FDA-approved vaccines and antivirals have been successfully developed and implemented for the prophylactic and therapeutic inte...
