Abstract: A composition including a substance that inhibits an expression or activity of c-src and its use in inhibiting aggregation and/or migration of ?-syn are disclosed. The composition may be a pharmaceutical composition and can be used for preventing or treating synucleinopathy. The substance can inhibit the signal transduction induced by ?-syn migrating to adjacent cells, thus mitigating the cytotoxic influence of ?-syn on the adjacent cells; and can inhibit the denaturation of monomeric ?-syn into aggregated ?-syn, which may be a major cause of synucleinopathy, and thus, can be beneficially used as a therapeutic agent for synucleinopathy.

Abstract: The present disclosure provides an anti-PD-L1/anti-LAG3 bispecific antibody capable to effectively block the interactions between PD-L1 and its receptor PD-1 and between LAG3 and its ligand (e.g., a MHC class II molecule and FGL1). The bispecific antibody may have high binding affinity to both of a PD-L1 protein (e.g., a human PD-L1 protein) and a LAG3 protein (e.g., a human LAG3 protein). Also provided are antibodies and fragments that have specificity to the PD-L1 or LAG3 protein alone, or antibodies and fragments having additional specificity to one or more other antigens.

Abstract: Provided herein are multispecific molecules comprising a first binding domain that specifically binds to polymeric immunoglobulin receptor (pIgR) and a second binding domain that specifically binds to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and related methods for the treatment of patients infected with SARS-CoV-2.

Abstract: The present disclosure relates to a novel anti-HER2 antibody or an antigen-binding fragment thereof used in the prevention or treatment of cancer, a chimeric antigen receptor including the same, and uses thereof. The antibody of the present disclosure is an antibody that specifically binds to HER2 which is highly expressed in cancer cells (particularly, breast cancer or gastric cancer cells), and binds to an epitope that is different from an epitope to which trastuzumab binds. When compared with trastuzumab, the antibody of the present disclosure exhibits better killing ability for HER2-unexpressed cancer cells which have non-reactivity (or resistance) to the trastuzumab antibody or have reduced sensitivity. In addition, when the anti-HER2 antibody of the present disclosure is administered in combination with trastuzumab, a synergistic killing ability is achieved for cancer cells on which the trastuzumab antibody acts.
