    Abstract: The present invention discloses a monoclonal antibody against nerve growth factor, and an encoding gene and use thereof. The monoclonal antibody comprises heavy chains comprising a heavy chain constant region and a heavy chain variable region, and light chains comprising a light chain constant region and a light chain variable region. The heavy chain variable region comprises three complementarity determining regions HCDR1, HCDR2 and HCDR3, and the light chain variable region comprises three complementarity determining regions LCDR1, LCDR2 and LCDR3. The monoclonal antibody can specifically bind to nerve growth factor, and can be used to detect the presence and/or level of nerve growth factor, as well as to prepare a drug for inhibiting the nerve growth factor-dependent proliferation of TF-1 cells, and for treating or preventing at least one of neuropathic pain, chronic pain, and inflammatory pain, thus having good application prospects and marketing value.

    Abstract: The present invention belongs to the field of immunology, and relates to an anti-IL-1β antibody and pharmaceutical composition thereof and use of the same. Specifically, the present invention relates to an anti-IL-1β antibody or an antigen-binding fragment thereof, wherein a heavy chain variable region of the antibody comprises HCDR1-HCDR3 with amino acid sequences set forth in SEQ ID NO: 17-SEQ ID NO: 19, respectively; and a light chain variable region of the antibody comprises LCDR1-LCDR3 set forth in SEQ ID NO: 20-SEQ ID NO: 22, respectively. The antibody disclosed herein can effectively bind to human IL-1β, block the binding of IL-1β to a receptor IL-1R1 thereof, and inhibit the activation of downstream signaling pathways of IL-1β; having the potential of being used for preparing a medicament for preventing and treating autoimmune diseases, cryopyrin-associated periodic syndromes in children and adults, systemic juvenile idiopathic arthritis, gouty arthritis, cardiovascular diseases or tumors.
