[Research Progress of Bispecific Antibodies in Treatment of Multiple Myeloma--Review].

Multiple myeloma (MM) is an incurable malignant plasma cell diseases, the incidence of which is increasing year by year. The application of immunomodulators drugs, proteasome inhibitors, anti-CD38 antibodies, CAR-T, and HSCT have significantly improved the prognosis of patients with MM, however new therapeutic tools need to be developed to improve the prognosis of patients with relapsed/refractory after conventional regimens treatment. Bispecific antibodies are a novel immunotherapeutic approach that generates immune synapses by binding to targets on malignant plasma cells and cytotoxic immune effector cells (T cells/natural killer cells), leading to T/NK cells activation and malignant plasma cell lysis.

[Research Progress of NK Cell Therapy in Multiple Myeloma Treatment --Review].

Multiple myeloma (MM) is a hematologic neoplasm characterized by malignant proliferation of monoclonal plasma cells in the bone marrow. NK cells, a class of innate lymphocytes with potent natural killer activity, are capable of recognizing and destroying tumor cells and virally infected cells, and have attracted attention as a potential anticancer therapy. In patients with MM, NK cells are suppressed in number and function, resulting in reduced immune surveillance and clearance of myeloma cells.

[Research Progress of Cancer-associated Fibroblasts in Hematolo- gic Malignancies --Review].

Cancer-associated fibroblasts （CAF） are a key component of the tumor microenvironment, which can secrete a variety of cytokines, chemokines and growth factors, directly and indirectly support cancer cells, also alter the immune cellular environment by inhibiting the activity of immune effector cells and recruiting immunosuppressive cells, thereby allowing cancer cells to evade immune surveillance. CAF has been proven to be associated with the development, progression, and poor prognosis of solid tumors. However, the role of CAF in hematological malignancies is still unclear.
