    GO:0002296    T-helper 1 cell lineage commitment    The process in which a CD4-positive, alpha-beta T cell becomes committed to becoming a T-helper 1 cell, a CD4-positive, alpha-beta T cell specialized to promote immunological processes often associated with resistance to intracellular bacteria, fungi, and protozoa, and pathological conditions such as arthritis.
    GO:0035745    T-helper 2 cell cytokine production    Any process that contributes to cytokine production by a T-helper 2 cell.
    GO:0045064    T-helper 2 cell differentiation    The process in which a relatively unspecialized T cell acquires specialized features of a T-helper 2 (Th2) cell. A Th2 cell is a CD4-positive, alpha-beta T cell that has the phenotype GATA-3-positive and produces interleukin-4.
    GO:0006968    cellular defense response    A defense response that is mediated by cells.
    GO:0071288    cellular response to mercury ion    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a mercury ion stimulus.
    GO:0006935    chemotaxis    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).
    GO:0008203    cholesterol metabolic process    The chemical reactions and pathways involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones. It is a component of the plasma membrane lipid bilayer and of plasma lipoproteins and can be found in all animal tissues.
    GO:0045189    connective tissue growth factor biosynthetic process    The chemical reactions and pathways resulting in the formation of CTGF, produced by human umbilical vein endothelial cells and by skin fibroblasts after activation with TGF-beta.
    GO:0042832    defense response to protozoan    Reactions triggered in response to the presence of a protozoan that act to protect the cell or organism.
    GO:0097028    dendritic cell differentiation    The process in which a precursor cell type acquires the specialized features of a dendritic cell. A dendritic cell is a leukocyte of dendritic lineage specialized in the uptake, processing, and transport of antigens to lymph nodes for the purpose of stimulating an immune response via T cell activation.
    GO:0097192    extrinsic apoptotic signaling pathway in absence of ligand    A series of molecular signals in which a signal is conveyed from the cell surface to trigger the apoptotic death of a cell. The pathway starts with withdrawal of a ligand from a cell surface receptor, and ends when the execution phase of apoptosis is triggered.
    GO:0007565    female pregnancy    The set of physiological processes that allow an embryo or foetus to develop within the body of a female animal. It covers the time from fertilization of a female ovum by a male spermatozoon until birth.
    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:0002227    innate immune response in mucosa    Any process of the innate immune response that takes place in the mucosal tissues.
    GO:0001774    microglial cell activation    The change in morphology and behavior of a microglial cell resulting from exposure to a cytokine, chemokine, cellular ligand, or soluble factor.
    GO:0043011    myeloid dendritic cell differentiation    The process in which a monocyte acquires the specialized features of a dendritic cell, an immunocompetent cell of the lymphoid and hemopoietic systems and skin.
    GO:0050868    negative regulation of T cell activation    Any process that stops, prevents, or reduces the frequency, rate or extent of T cell activation.
