Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation of peptide antigen via MHC class Ib.

Any process that modulates the frequency, rate, or extent of antigen processing and presentation of peptide antigen via MHC class Ib.

Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation of antigen via MHC class Ib.

Any process that stops, prevents, or reduces the frequency, rate, or extent of antigen processing and presentation of peptide antigen via MHC class Ib.

Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation.

Any process that stops, prevents, or reduces the frequency, rate, or extent of antigen processing and presentation.

Any process that modulates the frequency, rate, or extent of antigen processing and presentation.

Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation of peptide antigen via MHC class II.

Any process that modulates the frequency, rate, or extent of antigen processing and presentation of peptide antigen via MHC class II.

Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation of antigen (peptide or polysaccharide) via MHC class II.

Any process that stops, prevents, or reduces the frequency, rate, or extent of antigen processing and presentation of antigen (peptide or polysaccharide) via MHC class II.

Any process that modulates the frequency, rate, or extent of antigen processing and presentation of antigen (peptide or polysaccharide) via MHC class II.

The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet.

The movement of a basophil in response to an external stimulus.

The process in which a relatively unspecialized myeloid precursor cell acquires the specialized features of a thrombocyte, a nucleated cell found in all vertebrates but mammals involved in hemostasis.

The process in which a relatively unspecialized hemopoietic precursor cell acquires the specialized features of a leukocyte. A leukocyte is an achromatic cell of the myeloid or lymphoid lineages capable of ameboid movement, found in blood or other tissue.

The process in which a precursor cell type acquires the specialized features of a pro-T cell. Pro-T cells are the earliest stage of the T cell lineage but are not fully committed.

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

The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of T cell receptor genes. N regions are found at the V-D, D-D, V-J, and D-J recombinational junctions, depending on the T cell receptor gene.

The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of heavy chain immunoglobulin and T cell receptor genes. N regions are found at the V-D, D-D, V-J, and D-J recombinational junctions, depending on the immune receptor gene.
