Azygos Vein
|
D001401 |
[A vein which arises from the right ascending lumbar vein or the vena cava, enters the thorax through the aortic orifice in the diaphragm, and terminates in the superior vena cava.

B-Cell Activating Factor
|
D053264 |
[A tumor necrosis factor superfamily member that plays a role in the regulation of B-LYMPHOCYTE survival. It occurs as a membrane-bound protein that is cleaved to release an biologically active soluble form with specificity to TRANSMEMBRANE ACTIVATOR AND CAML INTERACTOR PROTEIN; B-CELL ACTIVATION FACTOR RECEPTOR; and B-CELL MATURATION ANTIGEN.

|
B-Cell Activation Factor Receptor
|
D053265 |
[A member of the tumor necrosis factor receptor superfamily that specifically binds B-CELL ACTIVATING FACTOR. It is found on B-LYMPHOCYTES and plays a role in maturation and survival of B-cells. Signaling by the activated receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.

|
B-Cell CLL-Lymphoma 10 Protein
|
D000074018 |
[A signal transducing adaptor protein that contains an N-terminal CARD DOMAIN and functions in the ADAPTIVE IMMUNE RESPONSE. It promotes PRO-CASPASE-9 maturation and APOPTOSIS, activation of NF-KAPPA B, and is a substrate for MALT1 PARACASPASE.
] |
|
B-Cell Lymphoma 3 Protein
|
D000081242 |
[A member of the I kappa B family, B-cell lymphoma 3-encoded (bcl-3) protein is involved in the regulation of TRANSCRIPTIONAL ACTIVATION of NF-KAPPA B target genes.
] |
|
B-Cell Maturation Antigen
|
D053301 |
[A member of the tumor necrosis factor receptor superfamily found on mature B-LYMPHOCYTES. It has specificity for B CELL ACTIVATING FACTOR and TUMOR NECROSIS FACTOR LIGAND SUPERFAMILY MEMBER 13. Signaling of the receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.

|
B-Lymphocytes
|
D001402 |
[Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.
] |
|
B-Lymphocytes, Regulatory
|
D060151 |
[B-cells that have a role in regulating the immune response including the production of CYTOKINES. This function is in addition to their traditional role in making antibodies.
] |
|
B30.2-SPRY Domain
|
D000071197 |
[A protein interaction domain that is characterized by a bent "beta-sandwich" consisting of two antiparallel beta-sheets. It occurs in eukaryotic proteins, including many TRIPARTITE MOTIF PROTEINS, which function in a variety of cellular processes.
] |
|
B7 Antigens
|
D060887 |
[A family of cell-surface proteins found on ANTIGEN-PRESENTING CELLS. B7 antigens are ligands for specific cell surface receptor subtypes found on T-CELLS. They play an immunomodulatory role by stimulating or inhibiting the T-CELL activation process.
] |
|
B7-1 Antigen
|
D018122 |
[A costimulatory ligand membrane glycoprotein that contains a V2 type and C2 IMMUNOGLOBULIN DOMAIN and is expressed by ANTIGEN-PRESENTING CELLS. It binds to CTLA-4 ANTIGEN with high specificity and to CD28 ANTIGEN with low specificity. The interaction of CD80 with CD28 ANTIGEN provides a costimulatory signal to T-LYMPHOCYTES, while its interaction with CTLA-4 ANTIGEN may play a role in inducing PERIPHERAL TOLERANCE.

|
B7-2 Antigen
|
D051940 |
[A costimulatory ligand glycoprotein that contains a C2 and V-type IMMUNOGLOBULIN DOMAIN. It is expressed by ANTIGEN-PRESENTING CELLS and binds to CD28 ANTIGEN with high specificity and to CTLA-4 ANTIGEN with low specificity. The interaction of CD86 with CD28 ANTIGEN provides a stimulatory signal to T-LYMPHOCYTES, while its interaction with CTLA-4 ANTIGEN may play a role in inducing PERIPHERAL TOLERANCE.

|
B7-H1 Antigen
|
D060890 |
[An inhibitory B7 antigen that contains V-type and C2 type immunoglobulin domains. It has specificity for the T-CELL receptor PROGRAMMED CELL DEATH 1 PROTEIN and provides negative signals that control and inhibit T-cell responses. It is found at higher than normal levels on tumor cells, suggesting its potential role in TUMOR IMMUNE EVASION.
