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 [goid 6954] [evidence IEA]; The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell [goid 7165] [evidence IEA]; A series of reactions initiated by the activation of the transcription factor NF-kappaB. NF-kappaB is sequestered by the inhibitor I-kappaB, and is released when I-kappaB is phosphorylated by activated I-kappaB kinase [goid 7249] [pmid 12032557] [evidence NAS]; A series of reactions initiated by the activation of the transcription factor NF-kappaB. NF-kappaB is sequestered by the inhibitor I-kappaB, and is released when I-kappaB is phosphorylated by activated I-kappaB kinase [goid 7249] [pmid 15276183] [evidence EXP]; The series of events in which a stimulus from a virus is received and converted into a molecular signal [goid 9597] [pmid 12032557] [evidence NAS]; An immune response mediated by immunoglobulins, whether cell-bound or in solution [goid 16064] [pmid 16123302] [evidence TAS]; Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interferon-gamma [goid 45078] [pmid 16286015] [evidence IDA]; Any process that activates or increases the frequency, rate or extent of the innate immune response, the organism's first line of defense against infection [goid 45089] [pmid 16123302] [evidence IDA]; Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interferon-alpha [goid 45356] [pmid 16286015] [evidence IDA]; Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interferon-beta [goid 45359] [pmid 16286015] [evidence IDA]; Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interleukin-8 [goid 45416] [pmid 16188996] [evidence IMP]; Reactions triggered in response to the presence of a virus that act to protect the cell or organism [goid 51607] [pmid 16188996] [evidence IMP]; The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell [goid 7165] [evidence IEA]; Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens [goid 45087] [evidence IEA]
