GO:0001774 microglial cell activation biological_process The change in morphology and behavior of a microglial cell resulting from exposure to a cytokine, chemokine, cellular ligand, or soluble factor. [GOC:mgi_curators, PMID:10626665, PMID:10695728, PMID:12580336, PMID:9893949]
GO:0006956 complement activation biological_process 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. [GO_REF:0000022, GOC:add, ISBN:0781735149]
GO:0006958 complement activation, classical pathway biological_process Any process involved in the activation of any of the steps of the classical pathway of the complement cascade which allows for the direct killing of microbes, the disposal of immune complexes, and the regulation of other immune processes. [GOC:add, ISBN:0781735149]
GO:0007267 cell-cell signaling biological_process Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions. [GOC:dos, GOC:mah]
GO:0016322 neuron remodeling biological_process The developmentally regulated remodeling of neuronal projections such as pruning to eliminate the extra dendrites and axons projections set up in early stages of nervous system development. [GOC:hb]
GO:0045087 innate immune response biological_process Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. [GO_REF:0000022, GOC:add, GOC:ebc, GOC:mtg_sensu]
GO:0048143 astrocyte activation biological_process A change in morphology and behavior of an astrocyte resulting from exposure to a cytokine, chemokine, cellular ligand, or soluble factor. [GOC:mgi_curators, PMID:10526094, PMID:10695728, PMID:12529254, PMID:12580336, PMID:9585813]
GO:0050808 synapse organization biological_process A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a synapse, the junction between a neuron and a target (neuron, muscle, or secretory cell). [GOC:ai, GOC:pr]
GO:0098883 synapse pruning biological_process A cellular process that results in the controlled breakdown of synapse. After it starts the process is continuous until the synapse has disappeared. [GOC:dos, PMID:12062020, PMID:18083105, PMID:22632716, PMID:29844190]
GO:0150062 complement-mediated synapse pruning biological_process Synaptic pruning mediated by complement system signaling. [GOC:aruk, GOC:bc, PMID:18083105, PMID:22632727, PMID:29844190]
GO:0150064 vertebrate eye-specific patterning biological_process Early postnatal vertebrate developmental process, during which axons of retinal ganglion cells (RGCs), transmitting overlapping inputs from both eyes, segregate into distinct eye-specific non-overlapping regions in the dorsal lateral geniculate nucleus (dLGN) of the thalamus. [GOC:aruk, GOC:bc, PMID:16025107, PMID:22632727, PMID:29322522]
GO:0005576 extracellular region cellular_component 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. [GOC:go_curators]
GO:0005602 complement component C1 complex cellular_component A protein complex composed of six subunits of C1q, each formed of the three homologous polypeptide chains C1QA, C1QB, and C1QB, and tetramer of two C1QR and two C1QS polypeptide chains. [GOC:add, ISBN:0781735149]
GO:0045202 synapse cellular_component The junction between an axon of one neuron and a dendrite of another neuron, a muscle fiber or a glial cell. As the axon approaches the synapse it enlarges into a specialized structure, the presynaptic terminal bouton, which contains mitochondria and synaptic vesicles. At the tip of the terminal bouton is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic terminal bouton secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. [GOC:aruk, ISBN:0198506732, PMID:24619342, PMID:29383328, PMID:31998110]
GO:0062023 collagen-containing extracellular matrix cellular_component An extracellular matrix consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that provides not only essential physical scaffolding for the cellular constituents but can also initiate crucial biochemical and biomechanical cues required for tissue morphogenesis, differentiation and homeostasis. The components are secreted by cells in the vicinity and form a sheet underlying or overlying cells such as endothelial and epithelial cells. [GOC:BHF, GOC:rph, PMID:21123617]
GO:0062167 complement component C1q complex cellular_component A protein-containing complex composed of six subunits of each of the three homologous polypeptide chains C1QA, C1QB, and C1QB. It is a subunit of the complement C1 complex. In addition to complement activation, C1q appears to have roles in homeostasis and cellular development, superoxide (O2-) production by neutrophils, blood coagulation and neurological synapse pruning.

GO:0098794 postsynapse cellular_component The part of a synapse that is part of the post-synaptic cell. [GOC:dos]
GO:0005581 collagen trimer cellular_component A protein complex consisting of three collagen chains assembled into a left-handed triple helix. These trimers typically assemble into higher order structures. [GOC:dos, GOC:mah, ISBN:0721639976, PMID:19693541, PMID:21421911]
