Binding Target  Glycoprotein.

Mechanism  The efficacy of delta-Fc and its truncated versions (delta1-28-Fc, delta1-33-Fc, delta1-39-Fc, delta13-48-Fc, delta28-48-Fc, delta7-48-Fc, delta18-48-Fc, delta1-17-Fc) in inhibiting Ebola virus (EBOV) entry was investigated, demonstrating specific binding to filovirus-permissive cells and inhibition of EBOV glycoprotein GP1,2 entry. These Fc-tagged peptides interfere with the viral entry process, potentially preventing superinfection of producer cells and inhibiting cell transduction with filoviruses. The mechanisms of action involve binding to cell surface receptors or disrupting key viral entry steps.
