- inflorescence morphogenesis
The process in which the anatomical structures of inflorescences are generated and organized. An inflorescence is the part of a seed plant body that is usually above ground and that can bear flowers.
- alpha-beta T cell activation by superantigen
The change in morphology and behavior of alpha-beta T cells resulting from exposure to a superantigen, a microbial antigen with an extremely potent activating effect on T cells that bear a specific variable region.
- sodium:potassium-exchanging ATPase complex
Sodium:potassium-exchanging ATPases are tetrameric proteins, consisting of two large alpha subunits and two smaller beta subunits. The alpha subunits bear the active site and penetrate the membrane, while the beta subunits carry oligosaccharide groups and face the cell exterior.
- V(D)J recombination
The process in which immune receptor V, D, and J, or V and J gene segments, depending on the specific receptor, are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- T cell receptor V(D)J recombination
The process in which T cell receptor V, D, and J, or V and J gene segments, depending on the specific locus, are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- somatic diversification of immune receptors by N region addition
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.
