Abstract: Disclosed are a novel antibody specifically binding to the tumor-immunosuppressant, TIGIT (T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif [ITIM] domain) or an antigen-binding fragment thereof, a nucleic acid encoding the antibody or the antigen-binding fragment thereof, a vector and a host cell including the nucleic acid, a method for producing the antibody or the antigen-binding fragment thereof, a pharmaceutical composition containing the antibody or the antigen-binding fragment thereof as an active ingredient, and uses of the pharmaceutical composition. The antibody specifically binding to TIGIT or the antigen-binding fragment thereof and the pharmaceutical composition containing the same as an active ingredient are preferably used for the treatment of cancer or tumors.

Abstract: Provided are a fusion protein having a CCL3 variant with improved in vivo persistency, protein stability and pharmacological activity and a use thereof, more particularly, a fusion protein comprising a CCL3 variant and an immunoglobulin Fc region and a use thereof as a therapeutic agent for lymphopenia, cancer or infection, in which an N-terminal amino acid of a wild-type CCL3? or CCL3? is deleted and an amino acid at a specific position is substituted with a different amino acid at the same position of the wild-type CCL3? or CCL3? in the CCL3 variant.
