The present invention relates to a mutated HPV18 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 (for example, HPV18 and HPV45, or HPV18, HPV45 and HPV59), 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.

Mutant of L1 protein of human papillomavirus type 18

Provided are a mutated HPV16 L1 protein (or a variant thereof), a sequence encoding the same and a method for preparing the same, as well as a virus-like particle comprising the same. The protein (or variant thereof) and the virus-like particle are capable of inducing neutralizing antibodies against at least two types of HPV (e.g., HPV16 and HPV35, or HPV16, HPV35, and HPV31), 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. Also provided are a use of the above protein and virus-like particle in the manufacture of a pharmaceutical composition or 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.

Mutant of L1 protein of human papillomavirus type 16

Provided are a mutated HPV58 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, 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.

Mutant of L1 protein of human papillomavirus type 58
