Provided are a mutated HPV51 L1 protein or a variant thereof, a coding sequence thereof, a preparation method therefor, and a virus-like particle containing same, wherein the protein or the variant and the virus-like particle thereof are capable of inducing neutralizing antibodies against at least two types of HPV (for example, HPV51 and HPV69, or HPV51, HPV69 and HPV26). Also provided is the use of the above-mentioned protein and the virus-like particle for preparing a pharmaceutical composition or a vaccine, wherein the pharmaceutical composition or the vaccine can be used to prevent infections of the at least two types of HPV and diseases caused by the infections, such as cervical cancer and condyloma acuminatum.

Human papilloma virus type 51 L1 protein mutants

The invention relates to a mutated HPV66 L1 protein (or a variant thereof), a sequence encoding the same, a method for preparing the same, and a virus-like particle comprising the same, wherein the protein (or a variant thereof) and the virus-like particle can induce the generation of neutralizing antibodies against at least two HPV types (e.g. HPV66 and HPV56, or HPV66, HPV56 and HPV53), and therefore can be used to prevent infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum. The invention further relates to the use of the protein and the virus-like particle in the manufacture of a pharmaceutical composition or a vaccine for preventing infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum.
