Class I here refers to classical class I molecules.
    GO:0002479    antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-dependent    The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC class I protein complex following intracellular transport via a TAP (transporter associated with antigen processing) pathway. The peptide is typically a fragment of a larger exogenous protein which has been degraded within the cell and is dependent on TAP transport from the cytosol to ER for association with the MHC class I molecule. Class I here refers to classical class I molecules.
    GO:0002480    antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-independent    The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC class I protein complex following intracellular transport via a pathway not requiring TAP (transporter associated with antigen processing). The peptide is typically a fragment of a larger exogenous protein which has been degraded within the cell. Class I here refers to classical class I molecules.
    GO:0002474    antigen processing and presentation of peptide antigen via MHC class I    The process in which an antigen-presenting cell expresses a peptide antigen on its cell surface in association with an MHC class I protein complex. Class I here refers to classical class I molecules.
    GO:0050830    defense response to Gram-positive bacterium    Reactions triggered in response to the presence of a Gram-positive bacterium that act to protect the cell or organism.
    GO:0006955    immune response    Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.
    GO:0002376    immune system process    Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
    GO:0060333    interferon-gamma-mediated signaling pathway    A series of molecular signals initiated by the binding of interferon-gamma to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription. Interferon gamma is the only member of the type II interferon found so far.
    GO:2001187    positive regulation of CD8-positive, alpha-beta T cell activation    Any process that activates or increases the frequency, rate or extent of CD8-positive, alpha-beta T cell activation.
    GO:2000566    positive regulation of CD8-positive, alpha-beta T cell proliferation    Any process that activates or increases the frequency, rate or extent of CD8-positive, alpha-beta T cell proliferation.
    GO:0002726    positive regulation of T cell cytokine production    Any process that activates or increases the frequency, rate, or extent of T cell cytokine production.
    GO:0001916    positive regulation of T cell mediated cytotoxicity    Any process that activates or increases the frequency, rate or extent of T cell mediated cytotoxicity.
    GO:0032729    positive regulation of interferon-gamma production    Any process that activates or increases the frequency, rate, or extent of interferon-gamma production. Interferon-gamma is also known as type II interferon.
    GO:2000568    positive regulation of memory T cell activation    Any process that activates or increases the frequency, rate or extent of memory T cell activation.
    GO:0050690    regulation of defense response to virus by virus    Any viral process that modulates the frequency, rate, or extent of the antiviral response of the host cell or organism.
    GO:0050776    regulation of immune response    Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.
    GO:0060337    type I interferon signaling pathway    A series of molecular signals initiated by the binding of a type I interferon to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription. Type I interferons include the interferon-alpha, beta, delta, episilon, zeta, kappa, tau, and omega gene families.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
cellular component
    GO:0012507    ER to Golgi transport vesicle membrane    The lipid bilayer surrounding a vesicle transporting substances from the endoplasmic reticulum to the Golgi.
    GO:0005794    Golgi apparatus    A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions.
    GO:0005797    Golgi medial cisterna    The middle Golgi cisterna (or cisternae).
    GO:0000139    Golgi membrane    The lipid bilayer surrounding any of the compartments of the Golgi apparatus.
    GO:0042612    MHC class I protein complex    A transmembrane protein complex composed of a MHC class I alpha chain and an invariant beta2-microglobin chain, and with or without a bound peptide antigen. Class I here refers to classical class I molecules.
    GO:0009986    cell surface    The external part of the cell wall and/or plasma membrane.
    GO:0031901    early endosome membrane    The lipid bilayer surrounding an early endosome.
    GO:0005783    endoplasmic reticulum    The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
    GO:0070971    endoplasmic reticulum exit site    An endoplasmic reticulum part at which COPII-coated vesicles are produced.
    GO:0071556    integral component of lumenal side of endoplasmic reticulum membrane    The component of the endoplasmic reticulum membrane consisting of the gene products that penetrate only the lumenal side of the membrane.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0030670    phagocytic vesicle membrane    The lipid bilayer surrounding a phagocytic vesicle.
