Background: BCMA/TNFRSF17
BCMA has two agonistic ligands: BAFF and a proliferation-inducing ligand (APRIL) (1,2). APRIL has higher affinity for BCMA than BAFF and the binding is mediated by CD138/syndeclin-1 (2,3). Activation of BCMA promotes the growth and survival of plasma cells, or MM cells in disease, through several signaling pathways such as NFkappaB, MEK/ERK, AKT, JNK, and p38 (1,2). In MM cells the BCMA activation and downstream signaling cascade functions to upregulate antiapoptotic proteins including Bcl-2, Bcl-xL, and Mcl-1 and protect the cells against therapeutic agents like dexamethasone (2,3).
Given its specific expression on plasma cells but not memory B cells, naive B cells, or hematopoietic stem cells, BCMA has garnered much interest as a therapeutic target for the treatment of MM (1-4). Current BCMA-targeted immunotherapy strategies include antibody-drug conjugates (ADC), chimeric antigen receptor (CAR) T cells, bispecific T cell engager (BiTE), and bispecific/trispecific antibodies (1-4). CAR T cell therapy in particular has demonstrated promising clinical results (2,4). Still, more research needs to be done to improve the efficacy and risk of relapse following CAR T cell therapy and may also include targeting additional antigens in combination with BCMA or utilizing pharmacological agents to increase antigen density (4).

This lyophilized preparation is stable for 12 months from date of receipt at -20 to -70 degrees C, preferably desiccated. Upon reconstitution, the preparation can be stored for 1 month at 2-8 degrees C under sterile conditions, and for 3 months at -20 degrees C to -70 degrees C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Stock solutions should be aliquoted and stored at < -20 degrees C. Further dilutions should be made in appropriate buffered solutions
