Any process that stops, prevents, or reduces the frequency, rate or extent of complement activation.

Any process that stops, prevents, or reduces the frequency, rate or extent of complement activation.

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

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 a peptide hormone stimulus. A peptide hormone is any of a class of peptides that are secreted into the blood stream and have endocrine functions in living animals.

A reproductive process occurring in the mother that results in birth.

The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi.

Any process that increases the concentration of calcium ions in the cytosol.

Any process that modulates the frequency, rate or extent of complement activation.

Any process that modulates the frequency, rate or extent of complement activation.

Any process that modulates the frequency, rate or extent of complement activation.

Any process that modulates the frequency, rate or extent of the classical pathway of complement activation.

Any process that modulates the frequency, rate or extent of signaling in response to detection of lipopolysaccharide.

Any process that contributes to cytokine production by a CD4-positive, alpha-beta T cell.

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

A phase of elevated metabolic activity, during which oxygen consumption increases; this leads to the production, by an NADH dependent system, of hydrogen peroxide (H2O2), superoxide anions and hydroxyl radicals.

Any process that stops, prevents, or reduces the frequency, rate or extent of complement activation.

Any process that modulates the frequency, rate or extent of complement-dependent cytotoxicity.

Any process that modulates the frequency, rate or extent of complement-dependent cytotoxicity.

Any process that activates or increases the frequency, rate or extent of CD4-positive, alpha-beta T cell activation.

Any process that activates or increases the frequency, rate or extent of CD4-positive, alpha-beta T cell proliferation.

The highly organized segment of the sperm flagellum which begins at the connecting piece and is characterized by the presence of 9 outer dense fibers (ODFs) that lie outside each of the 9 outer axonemal microtubule doublets and by a sheath of mitochondria that encloses the ODFs and the axoneme; the midpiece terminates about one-fourth of the way down the sperm flagellum at the annulus, which marks the beginning of the principal piece.

The region of the plasma membrane located at the apical end of the cell.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

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

The region of the plasma membrane located at the apical end of the cell.

Any of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions.

The lipid bilayer surrounding any of the compartments of the Golgi apparatus.

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 membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

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

Any of the vesicles of the constitutive secretory pathway, which carry cargo from the endoplasmic reticulum to the Golgi, between Golgi cisternae, from the Golgi to the ER (retrograde transport) or to destinations within or outside the cell.

The lipid bilayer surrounding a secretory granule.

The lipid bilayer surrounding any of the compartments of the endoplasmic reticulum (ER)-Golgi intermediate compartment system.

Any of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions.

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.

The lipid bilayer surrounding a ficolin-1-rich granule.
