The process in which a precursor cell type acquires the specialized features of a pre-B cell. Pre-B cells follow the pro-B cell stage of immature B cell differentiation and undergo rearrangement of heavy chain V, D, and J gene segments.

The process in which a precursor cell type acquires the specialized features of a pro-B cell. Pro-B cells are the earliest stage of the B cell lineage and undergo heavy chain D and J gene rearrangements, although they are not fully committed.

The process in which a naive natural killer cell acquires the specialized features of an effector natural killer T cell as part of an immune response.

The change in morphology and behavior of a natural killer cell resulting from exposure a cytokine, chemokine, cellular ligand, or soluble factor, leading to the initiation or perpetuation of an immune response.

The expansion of a natural killer cell population by cell division as part of an immune response.

A change in morphology and behavior of a lymphocyte resulting from exposure to a specific antigen, mitogen, cytokine, chemokine, cellular ligand, or soluble factor, leading to the initiation or perpetuation of an immune response.

The expansion of a B cell population by cell division following B cell activation during an immune response.

The process in which a precursor cell type acquires the specialized features of a natural killer cell progenitor.

The process in which a B cell acquires the specialized features of a memory B cell. Memory B cells are cells that can respond rapidly to antigen re-exposure by production of high-affinity antibody.

Any immunological memory process that can contribute to the formation of immunological memory.

The process in which a naive B cell acquires the specialized features of a mature or memory B cell during an immune response.

The process in which a precursor cell type acquires the specialized features of a myeloid progenitor cell. Myeloid progenitor cells include progenitor cells for any of the myeloid lineages.

The process in which a B cell acquires the specialized features of a plasma cell. A plasma cell is a lymphocyte which develops from a B cell and produces high amounts of antibody.

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.

The process in which a B cell in the spleen acquires the specialized features of a marginal zone B cell. Marginal zone B cells are localized in a distinct anatomical region of the spleen that represents the major antigen-filtering and scavenging area (by specialized macrophages resident there). It appears that they are preselected to express a BCR repertoire similar to B-1 B cells, biased toward bacterial cell wall constituents and senescent self-components (such as oxidized LDL).

The process in which a B cell in the spleen acquires the specialized features of a germinal center B cell. Germinal center B cells are rapidly cycling B cells which have downregulated IgD expression and exhibit high levels of binding by peanut agglutinin (PNA).

The expansion of a gamma-delta T cell population by cell division as part of an immune response.

The expansion of a T cell population by cell division as part of an immune response.

The change in morphology and behavior of a gamma-delta T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific, leading to the initiation or perpetuation of an immune response.

The expansion of an alpha-beta T cell population by cell division as part of an immune response.
