The invention discloses a
CTGF (
connective tissue growth factor) chimeric vaccine for treating
liver fibrosis. The antigenic
epitope of the
CTGF is inserted into c / e1
B cell epitope of
hepatitis b
virus core
antigen to form the
CTGF chimeric vaccine which can be assembled into
hepatitis B
core sample particles. Under the non-
adjuvant assistance, the chimeric vaccine can stimulate a body to generate high-valence anti-CTGF neutral
antibody. A mouse which is immunized by the chimeric vaccine is obviously relieved in
fibrosis degree generated after
carbon tetrachloride induction. According to the experimental
verification, the CTGF chimeric vaccine can be used for obviously restraining the activation intensity of hepatic stellate cells in the mouse liver, and also can be used for stimulating liver cells to multiply and restraining liver
apoptosis. Besides, the TGF-beta 1 and PDGF level in the immunized mouse is obviously reduced, so that the process of
liver fibrosis can be relieved in a facilitated manner. According to the results, the CTGF chimeric vaccine can be used for successfully restraining the carbon-
tetrachloride-induced mouse
liver fibrosis. Therefore, the CTGF chimeric vaccine is expected to be developed into effective means for treating the liver
fibrosis.
