|---|
| complement component C3a receptor activity | molecular function | Combining with the C3a 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. [GOC:add, GOC:mah, GOC:pg, GOC:signaling, ISBN:0781735149] |
| G protein-coupled receptor activity | molecular function | Combining with an extracellular signal and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. [GOC:bf, http://www.iuphar-db.org, Wikipedia:GPCR] |
| complement component C5a receptor activity | molecular function | Combining with the C5a 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. [GOC:add, GOC:mah, GOC:pg, GOC:signaling, ISBN:0781735149] |

|---|
| plasma membrane | cellular component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| azurophil granule membrane | cellular component | The lipid bilayer surrounding an azurophil granule, a primary lysosomal granule found in neutrophil granulocytes that contains a wide range of hydrolytic enzymes and is released into the extracellular fluid. [GOC:bf, PMID:17152095] |
| specific granule membrane | cellular component | The lipid bilayer surrounding a specific granule, a granule with a membranous, tubular internal structure, found primarily in mature neutrophil cells. Most are released into the extracellular fluid. Specific granules contain lactoferrin, lysozyme, vitamin B12 binding protein and elastase. [GOC:bf, PMID:7334549] |

| complement receptor mediated signaling pathway | biological process | The series of molecular signals generated as a consequence of a component of the complement pathway binding to a complement receptor. Such components include both whole complement proteins and fragments of complement proteins generated through the activity of the complement pathway. [GO_REF:0000022, GOC:add, ISBN:0781735149] |
| chemotaxis | biological process | The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis). [ISBN:0198506732] |
| G protein-coupled receptor signaling pathway | biological process | The series of molecular signals initiated by a ligand binding to its receptor, in which the activated receptor promotes the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, and ends with regulation of a downstream cellular process. The pathway can start from the plasma membrane, Golgi or nuclear membrane.

| blood circulation | biological process | The flow of blood through the body of an animal, enabling the transport of nutrients to the tissues and the removal of waste products. [GOC:mtg_heart, ISBN:0192800825] |
| positive regulation of vascular endothelial growth factor production | biological process | Any process that increases or activates the frequency, rate, or extent of production of vascular endothelial growth factor. [GOC:BHF, GOC:rl] |
| positive regulation of macrophage chemotaxis | biological process | Any process that increases the rate, frequency or extent of macrophage chemotaxis. Macrophage chemotaxis is the movement of a macrophage in response to an external stimulus. [GOC:BHF, GOC:dph, GOC:tb] |
| complement component C5a signaling pathway | biological process | A G protein-coupled receptor signaling pathway initiated by a C5a component of the complement pathway binding to a complement receptor, and ending with regulation of a downstream cellular process. C5a is a peptide derived from the C5 complement factor. [GOC:jc, PMID:15313431, Wikipedia:Complement_component_5a] |
| positive regulation of angiogenesis | biological process | Any process that activates or increases angiogenesis. [GOC:go_curators] |
| positive regulation of neutrophil chemotaxis | biological process | Any process that increases the frequency, rate, or extent of neutrophil chemotaxis. Neutrophil chemotaxis is the directed movement of a neutrophil cell, the most numerous polymorphonuclear leukocyte found in the blood, in response to an external stimulus, usually an infection or wounding. [GOC:dph, GOC:tb] |
| positive regulation of cytosolic calcium ion concentration | biological process | Any process that increases the concentration of calcium ions in the cytosol. [GOC:ai] |
| phospholipase C-activating G protein-coupled receptor signaling pathway | biological process | A G protein-coupled receptor signaling pathway in which the signal is transmitted via the activation of phospholipase C (PLC) and a subsequent increase in the intracellular concentration of inositol trisphosphate (IP3) and diacylglycerol (DAG). [GOC:dph, GOC:mah, GOC:signaling, GOC:tb, ISBN:0815316194] |
| inflammatory response | biological process | The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages. [GO_REF:0000022, ISBN:0198506732] |
