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.

The formation of a protein homotrimer, a macromolecular structure consisting of three noncovalently associated identical subunits.

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.

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.

An acute inflammatory response that involves non-antibody proteins whose concentrations in the plasma increase in response to infection or injury of homeothermic animals.

Any process involved in the activation of any of the steps of the complement cascade, which allows for the direct killing of microbes, the disposal of immune complexes, and the regulation of other immune processes; the initial steps of complement activation involve one of three pathways, the classical pathway, the alternative pathway, and the lectin pathway, all of which lead to the terminal complement pathway.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.

The process in which a microorganism (or other particulate material) is rendered more susceptible to phagocytosis by coating with an opsonin, a blood serum protein such as a complement component or antibody.

Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.

Any process in which the symbiont stops, prevents or reduces its increase in size or mass within the cells or tissues of the host organism. The host is defined as the larger of the organisms involved in the symbiotic interaction.

Any process in which the symbiont stops, prevents or reduces its increase in size or mass within the cells or tissues of the host organism. The host is defined as the larger of the organisms involved in the symbiotic interaction.

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

Any process that stops, prevents, or reduces the frequency, rate or extent of a multi-organism process in which a virus is a participant.

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

Reactions triggered in response to the presence of a Gram-positive bacterium that act to protect the cell or organism.

Reactions triggered in response to the presence of a Gram-positive bacterium that act to protect the cell or organism.

The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits.

The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits.

Any process mediated by an organism that results in the death of cells in the symbiont organism. The symbiont is defined as the smaller of the organisms involved in a symbiotic interaction.

The formation of a protein homotrimer, a macromolecular structure consisting of three noncovalently associated identical subunits.

The formation of a protein homotrimer, a macromolecular structure consisting of three noncovalently associated identical subunits.

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

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.

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

The external part of the cell wall and/or plasma membrane.
