Characterization of porcine CD19 and anti-CD19 monoclonal antibodies
Molecular Immunology, 2004CD19 is an important pan B cell marker and co-stimulatory protein in humans and mice. Efforts to further characterize B cell ontogeny in swine have been hampered by the lack of monoclonal antibodies (mAb) to valuable surface markers like Vpre-B, CD19, CD34 and CD43.

As a 95-kDa member of the immunoglobulin super-family expressed exclusively on B lymphocytes, CD19 is a critical co-receptor for B cell antigen receptor (BCR) signal transduction. Co-ligation of CD19 with the BCR synergistically enhances calcium release, mitogen-activated protein kinase activity and cell proliferation.

Retargeting CD19 Chimeric Antigen Receptor T Cells via Engineered CD19-Fusion Proteins
Molecular Pharmaceutics, 2019CD19-targeted chimeric antigen receptor (CAR) T-cells (CAR19s) show remarkable efficacy in the treatment of relapsed/refractory acute lymphocytic leukemia and Non-Hodgkin's lymphoma. However, the use of CAR T-cell therapy against CD19-negative hematological cancers and solid tumors has been challenging.

The Journal of Immunology, 1997
Abstract Establishing signal transduction thresholds that regulate B lymphocyte responses to foreign Ags and tolerance to self Ags is critical for humoral immune responses. The effects of altered signaling thresholds in B lymphocytes were examined in CD19-deficient mice and transgenic mice that expressed human CD19 at varying densities ...

Deficiencies in the CD19 complex
Clinical Immunology, 2018Signaling via the CD19-complex, consisting of CD19, CD81, CD21 and CD225, is critically important for B-cell development, differentiation and maturation. In this complex, each protein has its own distinct function. Over the past decade, 15 patients with antibody deficiency due to deficiencies in the CD19-complex have been described. These patients have

Blood, 2006
Abstract Current data on the leukemic stem cell (LSC) compartment in childhood acute lymphoblastic leukemia (ALL) are conflicting. The traditional hypothesis supposed that childhood ALL originates in a lymphoid progenitor cell and this is assumed to be consistent with the overall good treatment responses in pediatric patients.

CD19 Deficiency Due to Genetic Defects in the CD19 and CD81 Genes
2018CD19 is a transmembrane protein specifically expressed on B cells and acts together with CD21, CD81, and CD225 to reduce the threshold for B-cell antigen receptor (BCR) signaling. To date, 11 patients with childhood-onset hypogammaglobulinemia have been identified with CD19 deficiency due to mutations in the CD19 or CD81 genes.

BAFF-driven autoimmunity requires CD19 expression
Journal of Autoimmunity, 2015B cell activating factor of the tumor necrosis factor family (BAFF or BLyS) is a critical factor for B cell survival and maturation. BAFF-transgenic (BAFF-Tg) mice develop autoimmunity that resembles systemic lupus erythematosus (SLE) in a T cell-independent but MyD88-dependent manner, implicating toll-like receptor (TLR) signaling. The specific B cell
