Human papillomavirus type 11 antigen (HPV-11 antigen)

Human papillomavirus type 11 antigen encompasses the proteins encoded by HPV-11, chiefly the *L1 major capsid protein* used in vaccine development and immune assays[5][6]. HPV-11 antigens also include early proteins E4, E5, and E2, which participate in viral replication, modulation of cell cycle, and immune evasion[1][2][4]. HPV-11 is a low-risk type responsible for benign lesions such as genital warts and laryngeal papillomatosis but is infrequently oncogenic[7]. Vaccine antigens derived from HPV-11 L1 protein are clinically used in prophylactic vaccines, inducing neutralizing antibodies that confer protection against infection[5][6]. HPV-11 E4 and E5 proteins are being studied as molecular targets for diagnosis and potential therapies[1]. If more specific antigen information is needed (e.g., distinguishing between L1, L2, E4), the main immunogenic component for vaccines and serodiagnosis is **L1 protein** (the major capsid antigen)[5][6]. Antibodies and diagnostics may also target E4 and E2 proteins for research and clinical purposes[1][2].
