Mechanism  Peptide P2 acts against Ebola virus by stimulating cytotoxic T lymphocytes (CTLs) specific to the Ebola virus glycoprotein (GP). When used in immunization alongside liposome-encapsulated irradiated Ebola virus, P2 contributes to the generation of a CTL response aimed at targeting and eliminating virus-infected cells. This specificity was demonstrated by the enhanced lysis of target cells infected with vaccinia virus GP when effector cells from mice immunized with liposome-encapsulated virus were cultured with peptide P2, suggesting its role in inducing a more precise immune response against Ebola virus GP.
