OBSOLETE. The process in which the anatomical structures of the tail are generated and organized. The tail is the hindmost part of some animals.

The expansion of a NK T cell population by cell division.

The change in morphology and behavior of a mature or immature natural killer T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific.

Any process involved in the activation of any of the steps of the lectin pathway of the complement cascade which allows for the direct killing of microbes and the regulation of other immune processes.

Binding to a pentraxin, a member of a family of inflammatory proteins with a radially symmetric arrangement of five identical, noncovalently linked chains in a pentagonal array.

Binding to an opsonin, such as a complement component or antibody, deposited on the surface of a bacteria, virus, immune complex, or other particulate material.

The process in which a precursor cell type acquires the specialized features of a NK T cell.

The process in which a precursor cell type acquires the specialized features of an alpha-beta T cell. An alpha-beta T cell is a T cell that expresses an alpha-beta T cell receptor complex.

Binding to a collectin, a member of a group of structurally related pattern recognition molecules characterized by having a carbohydrate recognition domain of the C-type lectin family at the C-terminus and a collagenous domain at the N-terminus.

Combining with a collectin and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.

Any process that stops, prevents, or reduces the frequency, rate or extent of nervous system development, the origin and formation of nervous tissue.

Combining with the C3d product of the complement cascade and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.

The chemical reactions and pathways involving depsipeptides, a linear or cyclic compound composed of both amino acids and hydroxy acids in peptide and ester bonds respectively.

Combining with the C4b product of the classical complement cascade and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.

The chemical reactions and pathways resulting in the breakdown of depsipeptides, a linear or cyclic compound composed of both amino acids and hydroxy acids in peptide and ester bonds respectively.

The chemical reactions and pathways resulting in the formation of depsipeptides, a linear or cyclic compound composed of both amino acids and hydroxy acids in peptide and ester bonds respectively.

Any process that activates, maintains or increases the frequency, rate or extent of nervous system development, the origin and formation of nervous tissue.

OBSOLETE. The process in which the anatomical structures of a leg joint are generated and organized. The leg joint is a flexible region that separates the rigid sections of a leg to allow movement in a controlled manner. One example is the knee, which separates the leg tibia and femur.

The process, occurring in the embryo, by which the anatomical structures of the pectoral fin are generated and organized. Pectoral fins are bilaterally paired fins mounted laterally and located behind the gill covers of fish. These fins are used for lateral mobility and propulsion.
