Abstract: Related are an anti-TSLP antibody or an antigen-binding fragment thereof, nucleic acid molecules coding the same, and a method for preparing the same. The anti-TSLP antibody or the antigen-binding fragment thereof have high affinity to TSLP, capable of effectively binding with TSLP and blocking the proliferative effect of TSLP with respect to Ba/F3-hTSLPR-hIL7R? cells, and blocking the capability of TSLP in activating and secreting cytokines with respect to PBMC. At the same time, further related are a medicinal composition comprising the antibody or the antigen-binding fragment thereof, and uses of the composition in preparing a medicament for preventing and/or treating asthma, allergic inflammation, an allergic reaction or autoimmune disease.

Abstract: A BLyS antibody, preparation method therefor and application thereof, the BLyS antibody comprising one or more of CDR1, CDR2 and CDR3 of a heavy chain variable region of the BLyS antibody, and/or one or more of CDR1, CDR2 and CDR3 of a light chain variable region of the BLyS antibody. An amino acid sequence of the antibody is shown in a sequence listing. The BLyS antibody has a high affinity, and may observably and effectively seal a BLyS protein at a protein level and a cell level, and prevent the BLyS protein from binding to a receptor. The BLyS antibody lacks a cross-reaction with homologous protein antigens such as human APRIL, and enjoys good biological activity. The BLyS antibody may inhibit the proliferation of human BLyS-induced mouse B cells and may therefore be used for preparing a drug for preventing or treating diseases associated with BLyS expression or dysfunction.

Abstract: Anti-PD-1 antibodies and antigen-binding fragments thereof are described. Also described are nucleic acids encoding the antibodies, compositions comprising the antibodies, and methods of producing the antibodies and using the antibodies for treating or preventing diseases such as cancers and autoimmune diseases.

Abstract: The present invention provides an anti-C5aR antibody and a preparation method and use thereof. The anti-C5aR antibody comprises one or more of the followings: a heavy chain CDR1, heavy chain CDR2 or heavy chain CDR3 of a heavy chain variable region of an anti-C5aR antibody, and one or more of the followings: a light chain CDR1, light chain CDR2 or light chain CDR3 of a light chain variable region of the anti-C5aR antibody. The anti-C5aR antibody has a high affinity to human C5aR protein and can block the binding of the C5aR protein to a C5a, thus downregulating or switching off a corresponding signaling pathway, stopping C5a directed migration of a neutrophil in vitro and inhibiting chemotaxis of the neutrophil.
