B cell differentiation

The process in which a precursor cell type acquires the specialized features of a B cell. A B cell is a lymphocyte of B lineage with the phenotype CD19-positive and capable of B cell mediated immunity.

B-1 B cell proliferation

The expansion of a B-1 B cell by cell division. Follows B cell activation.

B cell apoptotic process

Any apoptotic process in a B cell, a lymphocyte of B lineage with the phenotype CD19-positive and capable of B cell mediated immunity.

B-1 B cell lineage commitment

The process in which an immature B cell becomes committed to become a B-1 B cell.

B-1 B cell differentiation

The process in which a hemopoietic stem cell acquires the specialized features of a B-1 B cell. B-1 B cells are a distinct subset of B cells characterized as being CD5 positive, found predominantly in the peritoneum, pleural cavities, and spleen, and enriched for self-reactivity.

neuromedin B receptor binding

Binding to a neuromedin B receptor.

follicular B cell differentiation

The process in which a B cell in the spleen acquires the specialized features of a follicular B cell. Follicular B cells are major population of mature recirculating B cells in the spleen and are located in the B-cell follicle region.

B cell proliferation

The expansion of a B cell population by cell division. Follows B cell activation.

type B pancreatic cell fate commitment

The commitment of a cell to a type B pancreatic cell fate and its capacity to differentiate into a type B pancreatic cell. A type B pancreatic cell is a cell located towards center of the islets of Langerhans that secretes insulin.

obsolete cytochrome b/b6

OBSOLETE. Diheme cytochrome b; cytochrome b has the hemes b(562) and b(566) and is a component of the mitochondrial respiratory chain complex III. Cytochrome b6 is a component of bc complex acting between photosystems II and I of photosynthesis.
