Intergalactic travel Intergalactic travel is travel between galaxies, and it is even more difficult than interstellar travel. At the speed of light, travelling from Earth in the Milky Way galaxy to the Andromeda Galaxy (the nearest major galaxy) would take roughly two and a half million years from the perspective of observers on Earth, but would take an arbitrarily short amount of time for the traveller (due to the effects of time dilation), depending on exactly how close to the speed of light their vessel is traveling.

The field is similar to architecture in that it deals with structures and load bearing walls.
Interior decoration Interior decoration or décor is the art of decorating a room so that it is attractive, easy to use, and functions well with the existing architecture. The goal of interior decoration is to provide a certain "feel" for the room; it encompasses applying wallpaper, painting walls and other surfaces, choosing furniture and fittings, such as light fixtures, and providing other decorations for the area such as paintings, sculptures and carpets.
Interior design Interior design is the process of shaping the experience of interior space, through the manipulation of spatial volume as well as surface treatment. Not to be confused with interior decoration, interior design draws on aspects of environmental psychology, architecture, product design and furniture design in addition to traditional decoration.

Interjurisdictional immunity In Canadian Constitutional law, interjurisdictional immunity is the legal doctrine that prevents a law from being applied to matters outside of the constitutional jurisdiction of the enacting head of power. For example, where a provincial law is found to intrude into a matter in the jurisdiction of the federal government the law will be interpreted through the “reading down” doctrine to exclude that matter.
Interlace (bitmaps) Interlacing is a method of encoding a bitmap image such that a person who has partially received it sees a degraded copy of the entire image. When communicating over a slow communications link, this is often preferable to seeing a perfectly clear copy of one part of the image, as it helps the viewer decide more quickly whether to abort or continue the transmission.

Interleukin Interleukins are a group of cytokines (secreted signaling molecules) that were first seen to be expressed by white blood cells (leukocytes, hence the -leukin) as a means of communication (inter-). The name is something of a relic though; it has since been found that interleukins are produced by a wide variety of bodily cells.
Interleukin 1 Interleukin-1 (IL-1) is one of the first cytokines ever described. Its initial discovery was as a factor that could induce fever, control lymphocytes, increase the number of bone marrow cells and cause degeneration of bone joints.
Interleukin 10 Interleukin-10 (IL-10 or IL10), also known as human cytokine synthesis inhibitory factor (CSIF), is an anti-inflammatory cytokine, capable of inhibiting synthesis of pro-inflammatory cytokines like Interferon-gamma, IL-2, IL-3, TNFα and GM-CSF by cells such as macrophages and the Type 2 T helper cells. However, it is also stimulatory towards certain T cells, mast cells and B cells.
Interleukin 13 Interleukin 13 (IL-13) is a cytokine secreted by many cell types, but especially T helper type 2 (Th2) cells, that is an important mediator of allergic inflammation and disease. In addition to effects on immune cells that are similar to those of the closely related cytokine IL-4, IL-13 is more importantly implicated as a central mediator of the physiologic changes induced by allergic inflammation in many tissues.
Interleukin 15 Interleukin 15 (IL-15) is a cytokine with structural similarity to IL-2 that is secreted by mononuclear phagocytes (and some other cells) following infection by virus(es). This cytokine induces cell proliferation of natural killer cells; cells of the innate immune system whose principal role is to kill virally infected cells.
Interleukin 16 Interleukin 16 (IL-16) is a cytokine that released by a variety of cells (including lymphocytes and some epithelial cells) that has been characterized as a chemoattractant for certain immune cells expressing the cell surface molecule CD4.
Interleukin 18 Interleukin-18 (IL-18) is a cytokine produced by macrophages that belongs to the IL-1 superfamily. IL-18 works together with IL-12 to induce cell-mediated immunity following infection with microbial products like lipopolysaccharide (LPS).
Interleukin 19 Interleukin-19 is a cytokine that belongs to the IL-10 family of cytokines along with several other interleukins including IL-10, IL-20, IL-22, IL-24, IL-26, and several virus-encoded cytokines. It signals through the same cell surface receptor (IL-20R) that is used by IL-20 and IL-24.
Interleukin 2 Interleukin-2 (IL-2) is an interleukin, or hormone of the immune system that is instrumental in the body's natural response to microbial infection and in discriminating between foreign (nonself) and self. IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes, the cells that are responsible for immunity.
Interleukin 20 Interleukin-20 (IL-20) is a protein belonging to the IL-10 family of cytokines. IL-20 is produced by activated keratinocytes and monocytes and transmits an intracellular signal through two distinct cell-surface receptor complexes on keratinocytes and other epithelial cells.
Interleukin 21 Interleukin 21 (IL-21), is a cytokine that has potent regulatory effects on cells of the immune system, including natural killer (NK) cells and cytotoxic T cells that can destroy virally infected or cancerous cells. Parrish-Novak J.
Interleukin 22 Interleukin-22 (IL-22) is a cytokine with homology to IL-10 that was originally called IL-10-related T cell-derived inducible factor (IL-TIF). Human IL-TIF activates the transcription factors stat-1 and stat-3 in several hepatoma cell lines and up-regulates production of acute phase proteins such as serum amyloid A, 1-antichymotrypsin and haptoglobin in HepG2 human hepatoma cells.
Interleukin 23 Interleukin-23 (IL-23) is a heterodimeric cytokine consisting of two subunits, one called p40, which is shared with another cytokine, IL-12, and another called p19 (the IL-23 alpha subunit). IL-23 is an important part of the inflammatory response against infection.
Interleukin 24 Interleukin 24 (IL-24) is a cytokine belonging to the IL-10 family of cytokines that signals through two heterodimeric receptors: IL-20R1/IL-20R2 and IL-22R1/IL-20R2. This interleukin is also known as Melanoma differentiation-associated 7 (mda-7) due to its discovery as a tumour suppressing protein.
Interleukin 26 Interleukin-26 (IL-26) is a 171-amino acid protein, which is similar in amino acid sequence to interleukin 10. It was originally called AK155 and is composed of a signal sequence, 6 helices, and 4 conserved cysteine residues.
Interleukin 27 Interleukin-27 (IL-27) is a heterodimeric cytokine belonging to the IL-12 family that is composed of two subunits, Epstein-Barr virus (EBV)-induced gene 3 (EBI3) (also known as IL-27B) and IL27-p28 (also called IL-28).F.
Interleukin 30 Interleukin-30 (IL-30) is a protein with a molecular weight of 28 kilodaltons, which forms one chain of the heterodimeric cytokine called interleukin 27 (IL-27), thus is sometimes called IL27-p28. The other chain of IL-27 is a molecule called Epstein-Barr induced gene-3 (EBI3).
Interleukin 32 Interleukin 32 (IL-32) is a cytokine that can induce cells of the immune system (such as monocytes and macrophages) to secrete tumor necrosis factor alpha (TNF-α) in addition to chemokines such as IL-8 and MIP-2/CXCL2.Kim SH, Han SY, Azam T, Yoon DY, Dinarello CA.
Interleukin 33 Interleukin 33 (IL-33) is a cytokine that is structurally related to IL-1, which induces helper T cells to produce type 2 cytokines. This cytokine was previously called NF-HEV because it appeared to play a role as a nuclear factor (NF) in high endothelial venules (HEVs).
Interleukin 4 Interleukin-4, abbreviated IL-4, is a cytokine with many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of CD4+ T-cells into Th2 cells. It is a key regulator in humoral and adaptive immunity.
Interleukin 6 Interleukin-6 (IL-6) is a pro-inflammatory cytokine secreted by T cells and macrophages to stimulate immune response to trauma, especially burns or other tissue damage leading to inflammation. In terms of host response to a foreign pathogen, IL-6 has been shown, in mice, to be required for resistance against the bacterium, Streptococcus pneumoniae .
Interleukin 7 Interleukin 7 (IL7) is a hematopoietic growth factor secreted by the Stromal cells of the red marrow capable of stimulating the proliferation of lymphoid progenitors. It is important for proliferation during certain stages of B-cell maturation, T and NK cell survival, development and homeostasis (From UniProt IL7_HUMAN).
Interleukin 8 Interleukin-8 (IL-8) is a chemokine produced by macrophages and other cell types such as epithelial cells. When first encountering an antigen, the primary cells to encounter it are the macrophages who phagocytose the particle.
Interleukin-3 receptor The interleukin-3 receptor (also known as CD123 antigen) is a molecule found on cells which helps transmit the signal of interleukin-3, a soluble cytokine important in the immune system. The gene coding for the receptor is located in the pseudoautosomal region of the X and Y chromosomes.
Interlibrary loan Interlibrary loan (abbreviated ILL, and sometimes called interloan, document delivery, or document supply etc.) is a service whereby a user of one library can borrow books, videos, DVDs, sound recordings, microfilms, or receive photocopies of articles in magazines that are owned by another library.

Interlock diagram An interlock diagram is a real or imagined diagram that plots the actual interactions, physical, political, social, environmental between all entities within human societies. Each node is a specific activity such as a power station, or a policy such as controlled rent.
Interlock Protocol The Interlock Protocol, as described by Ron Rivest and Adi Shamir, was designed to frustrate eavesdropper attack against two parties that use an anonymous key exchange protocol to secure their conversation. A further paper proposed using it as an authentication protocol, which was subsequently broken.
Interlock research Interlock Research is related to but broader than the notions of Corporate Interlocks and the Collaboratory. This idea is based on the notion that the looming environmental and other catastrophes; social, medical, health and other organizations; policy generally not working efficiently, are caused in large part by the failure for active professionals within and across different organizations; or even within the same organization to communicate at a lateral level directly with each other or their electronic avatars, leading to unintended and undesirable interactions and consequences.
Interlocking In railway signaling, an interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions, crossings, and so forth. The signaling appliances and tracks are sometimes collectively referred to as an interlocking plant.
Interlocking directorate Interlocking directorate refers to the practice of members of corporate board of directors serving on the boards of multiple corporations. This practice, although widespread and lawful, raises questions about the quality and independence of board decisions.
Interlocking spurs Interlocking spurs occur in the top part of a river course in upland areas. The water cannot erode the hard rock as easily as soft rock, so eventually the course of the river reflects this and ridges are produced when a river twists and turns around obstacles of harder rock on its downward path.
Interlocking tower An interlocking tower is an often towerlike structure or building housing the levers for working railroad switches and trackside signals. Its function is therefore that of a control point for movement, course, direction, and speed of trains.
