Fc Receptor (FcR)
Fc Receptor
Fc Receptors (FcR) are a class of cell surface receptors that can recognize and bind to the Fc region of immunoglobulins, playing an important role in processes such as the immune response and immune regulation. According to the types of immunoglobulins they recognize, FcR can be classified into FcγR, FcεR, FcαR, etc. According to their functional characteristics, they can be divided into activating FcR and inhibitory FcR. FcR mediate the phagocytosis of immune cells, prompting phagocytes to eliminate antigenic foreign substances such as pathogens. FcR also participate in ADCC, which activates NK cells and other cells to kill target cells, affecting the immune response. In addition, FcR can clear immune complexes and prevent them from depositing in tissues and triggering inflammation. Abnormal functions or dysregulated expressions of FcR can lead to autoimmune diseases and allergic diseases. In tumors, FcR are involved in both the immune escape of tumor cells and can serve as targets for immunotherapy[1][2].

Cusatuzumab
0 ImagesSynonyms: ARGX-110Cusatuzumab (ARGX-110) is a selective competitive blocker targeting CD70 (with an equilibrium dissociation constant of 17 pM for binding to human CD70). Cusatuzumab also possesses enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) activity. It is a humanized IgG1 monoclonal antibody, artificially synthesized through humanization and genetic engineering modifications (CH2 region mutation to enhance effector function). Cusatuzumab has a dual mechanism of action: firstly, it competitively blocks the interaction between CD70 and CD27, inhibiting the CD27-NF-κB signaling pathway, reducing regulatory T cell (Treg) activation and tumor cell proliferation; secondly, by enhancing binding to FcγRIIIa, it mediates ADCC and antibody-dependent cellular phagocytosis (ADCP), directly lysing CD70-positive tumor cells. Cusatuzumab can efficiently eliminate leukemia stem cells (LSCs), induce tumor cell differentiation and apoptosis, restore immune surveillance, and target CD70-positive tumors. Cusatuzumab is used in the study of acute myeloid leukemia (AML).
