Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.

The process in which an antigen-presenting cell expresses lipid antigen of endogenous origin in association with an MHC class Ib protein complex on its cell surface. Class Ib here refers to non-classical class I molecules, such as those of the CD1 family.

Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.

The process in which a precursor cell type acquires the specialized features of a NK T cell.

Any process that activates or increases the frequency, rate or extent of T cell mediated cytotoxicity.

The change in morphology and behavior of a mature or immature T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific, leading to the initiation or perpetuation of an immune response.

The series of events in which a stimulus from a bacterium is received and converted into a molecular signal.

The process in which an antigen-presenting cell expresses antigen (peptide or lipid) on its cell surface in association with an MHC protein complex.

Any process that modulates the frequency, rate or extent of immature T cell proliferation in the thymus.

The attachment of a cell to a cell of a different type via adhesion molecules.

Any process that activates or increases the rate or extent of T cell proliferation.

Any process that activates or increases the rate or extent of T cell proliferation.

Any process that stimulates, induces or increases the rate of macrophage activation.

The process in which T cells that express T cell receptors that are restricted by self MHC protein complexes and tolerant to self antigens are selected for further maturation.

The process of sparing immature T cells in the thymus which react with self-MHC protein complexes with low affinity levels from apoptotic death.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interferon-gamma.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interleukin-2.

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.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interleukin-4.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interleukin-4.

The process in which an antigen-presenting cell expresses lipid antigen of exogenous origin in association with an MHC class Ib protein complex on its cell surface. Class Ib here refers to non-classical class I molecules, such as those of the CD1 family.

Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.

Any process that activates or increases the frequency, rate or extent of natural killer T cell activation.

Any process that activates or increases the frequency, rate or extent of natural killer T cell differentiation.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of the plasma 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.

The component of the plasma 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.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A small lytic vacuole that has cell cycle-independent morphology and is found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions.

A membrane-bounded organelle that receives incoming material from primary endocytic vesicles that have been generated by clathrin-dependent and clathrin-independent endocytosis; vesicles fuse with the early endosome to deliver cargo for sorting into recycling or degradation pathways.

A prelysosomal endocytic organelle differentiated from early endosomes by lower lumenal pH and different protein composition. Late endosomes are more spherical than early endosomes and are mostly juxtanuclear, being concentrated near the microtubule organizing center.

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).

The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

The external part of the cell wall and/or plasma membrane.

The external part of the cell wall and/or plasma membrane.

The external part of the cell wall and/or plasma membrane.
