The regulated release of parathyroid hormone into the circulatory system.

The series of molecular signals initiated by binding of Wnt protein to a frizzled family receptor on the surface of the target cell contributing to the specification of the animal/vegetal axis of an oocyte.

Grouping of smoothened or patched receptors in a cilium, contributing to the smoothened signaling pathway.

Any process in which an organism increases the frequency, rate or extent of blood mast cell degranulation in another organism.

Any process that activates or increases the frequency, rate or extent of mast cell degranulation.

The series of molecular signals generated as a consequence of activation of the transmembrane protein Smoothened contributing to the dorsal/ventral pattern of the neural tube.

OBSOLETE. The chemical reactions and pathways performed by an organism resulting in the hydrolysis of proteins in another organism by cleavage of their peptide bonds.

The process in which a venous blood vessel endothelial cell acquires specialized features of a lymphatic vessel endothelial cell, a thin flattened cell that lines the inside surfaces of lymph vessels.

Maintaining the zonula adherens junction, the cell-cell adherens junction formed near the apex of epithelial cells.

The establishment, maintenance and elaboration of a line that delineates the mouth and the anus of an embryo.

The series of molecular signals initiated by an extracellular ligand binding to a transforming growth factor beta receptor on the surface of a target cell, which contributes to the specification of the oral/aboral axis.

The commitment of a venous blood vessel endothelial cell to a lymphatic endothelial cell fate and its capacity to differentiate into a lymphatic endothelial cell.

The process in which the developmental fate of a cell becomes restricted such that it will develop into an epithelial cell.

The chemical reactions and pathways resulting in the formation of fas ligand (FasL or CD95L), an antigen originally found to be expressed on the cell surface of activated human T-lymphocytes and B-lymphocytes and a variety of malignant human lymphoid cell lines.

A specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters cross the synaptic cleft and transmit the signal to the postsynaptic membrane.

OBSOLETE. The chemical reactions and pathways resulting in the formation of neurotransmitter receptors.

The chemical reactions and pathways involving a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.
