Application: LLO (190–201) is a helper T-cell epitope derived from listeriolysin O, a major virulence factor of Listeria monocytogenes. This peptide is presented by MHC class II molecules and elicits a strong LLO190-specific CD4⁺ T-cell response. LLO (190–201) is commonly used in infection biology and immunology research to study antigen presentation, T-helper cell activation, cellular immunity, and host responses to intracellular bacterial pathogens. It is also valuable in vaccine research, immune challenge models, and studies of protective immunity involving Listeria infection and MHC class II-restricted T-cell responses.
