The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

Any process that stops, prevents, or reduces the frequency, rate or extent of blood coagulation.

A process that solubilizes fibrin in the bloodstream of a multicellular organism, chiefly by the proteolytic action of plasmin.

A series of reactions that takes place outside the cell occurring in response to tissue damage and initiated within blood plasma by the action of activated Factor XII (Hageman Factor) on prekallikrein to convert it to plasma kallikrein, and the subsequent reaction of plasma kallikrein with high molecular weight kininogen. The ultimate product of the plasma kallikrein-kinin cascade is bradykinin, an agent known to induce smooth muscle contraction, vasoconstriction, and increased vascular permeability.

The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.

The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.

The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.

The process in which the sperm binds to the zona pellucida glycoprotein layer of the egg. The process begins with the attachment of the sperm plasma membrane to the zona pellucida and includes attachment of the acrosome inner membrane to the zona pellucida after the acrosomal reaction takes place.

The whole of the physical, chemical, and biochemical processes carried out by multicellular organisms to break down ingested nutrients into components that may be easily absorbed and directed into metabolism.

The chemical reactions and pathways involving cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom.

The controlled self-propelled movement of a cell from one site to a destination guided by molecular cues. Cell migration is a central process in the development and maintenance of multicellular organisms.

An immune response against microbes mediated through a body fluid. Examples of this process are seen in the antimicrobial humoral response of Drosophila melanogaster and Mus musculus.

Any process that activates or increases the frequency, rate or extent of blood coagulation.

The proteolytic processing of an inactive enzyme to an active form.

The regulated exocytosis of secretory granules containing preformed mediators such as proteases, lipases, and inflammatory mediators by a neutrophil.

The orderly movement of an endothelial cell into the extracellular matrix to form an endothelium.

A process that begins with venom being forced into an organism by the bite or sting of another organism, and ends with the resultant activation, maintenance or an increase in the frequency, rate or extent of platelet aggregation in the bitten organism.

A process that begins with venom being forced into an organism by the bite or sting of another organism, and ends with the resultant hydrolysis of proteins in of the bitten organism.

The process which begins with venom being forced into an organism by the bite or sting of another organism, and ends with fibrinogenolysis, a process that degrades fibrinogen at a variety of Arg-Lys bonds, thus impairing fibrinogen clotting in the bloodstream of the bitten/stung organism.

Any process leading to the attainment of the full functional capacity of a protein.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

Any membrane-enclosed lumen that is part of a tertiary granule.
