Cooperation Seeking

Creative Biolabs is interested in collaborating with potential partners (include but not limit to major pharma or biotech firms) to further co-develop ADCC-enhanced CD19 antibody. For commercial partners interested in our ADCC-enhanced therapeutic antibodies, Creative Biolabs welcomes collaboration. Here are two ways for your choice, and please contact us for more details.
1) Collaborate with us and co-develop the programs from discovery phase to IND enabling. Costs will be shared.
2) Become a licensed candidate of our programs.
Looking forward to cooperating with you in the near future.
Official Name
CD19
Full Name
CD19 molecule
Background
Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
Alternative Names
CD19; CD19 molecule; B4; CVID3; B-lymphocyte antigen CD19; differentiation antigen CD19; T-cell surface antigen Leu-12; B-lymphocyte surface antigen B4

Cellular Localization

Involvement in Disease
Its related pathways are RET signaling and B cell receptor signaling pathway (KEGG).
Related Pathways
As a co-receptor of b cell antigen receptor complex (BCR) on b lymphocytes. Lower the threshold of downstream signaling pathway activation and trigger b-cell response to antigen (PubMed: 2463100, PubMed: 1373518, PubMed: 16672701). Activating the signaling pathway leads to the activation of phosphatidylinositol 3-kinase and mobilization of intracellular Ca(2+) storage (PubMed:9382888, PubMed:9317126, PubMed:12387743, PubMed:16672701). Not needed in the early steps of bone marrow B cell differentiation (PubMed:9317126). Necessary for normal differentiation of B-1 cells (similarity). Normal B cell differentiation and proliferation are required to respond to antigen challenges (PubMed: 2463100, PubMed: 1373518). Requires normal levels of serum immunoglobulins, and high-affinity antibodies produced upon antigen challenge (PubMed:9317126, PubMed:12387743, PubMed:16672701).

Description
Blinatumomab is a bispecific T-cell conjugate (BiTE) that selectively acts and guides the human immune system against tumor cells. In 2014, the product was approved by the US Food and Drug Administration under the accelerated approval program and used as a second-line treatment for Philadelphia chromosome-negative relapse or refractory acute lymphoblastic leukemia. Blinatumomab specifically targets the CD19 antigen present on B cells.
Indication
Refractory B cell precursor Acute lymphoblastic leukemia
Relapsed B cell precursor Acute lymphoblastic leukemia
Synonyms
AMG103, MT103

Blinatumomab is a CD19-specific bispecific CD3 T cell adaptor that can simultaneously target CD19 expressed on the surface of cells of the B lineage and CD3 expressed on the surface of T cells. It activates endogenous T cells by linking CD3 in the T cell receptor (TCR) complex with CD19 on benign and malignant B cells, mediating the release of inflammatory cytokines and the proliferation of T cells, which leads to CD19 + Redirected lysis of cells.
