Antigen Molecule capable of inducing an immune response (to produce an antibody) in the host organism

In immunology, an antigen (Ag) is a molecule or molecular structure, such as may be present at the outside of a pathogen, that can be bound to by an antigen-specific antibody (Ab) or B cell antigen receptor (BCR). The presence of antigens in the body normally triggers an immune response. The term "antigen" originally described a structural molecule that binds specifically to an antibody only in the form of native antigen. It was expanded later to refer to any molecule or a linear molecular fragment after processing the native antigen that can be recognized by T-cell receptor (TCR). BCR and TCR are both highly variable antigen receptors diversified by somatic V(D)J recombination. Both T cells and B cells are cellular components of adaptive immunity. The Ag abbreviation stands for an antibody generator.

Antibody immune system protein

An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen, via the fragment antigen-binding (Fab) variable region. Each tip of the "Y" of an antibody contains a paratope that is specific for one particular epitope on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly. Depending on the antigen, the binding may impede the biological process causing the disease or may activate macrophages to destroy the foreign substance. The ability of an antibody to communicate with the other components of the immune system is mediated via its Fc region, which contains a conserved glycosylation site involved in these interactions. The production of antibodies is the main function of the humoral immune system.

Cyberpunk is a subgenre of science fiction in a dystopian futuristic setting that tends to focus on a "combination of low-life and high tech" featuring advanced technological and scientific achievements, such as artificial intelligence and cybernetics, juxtaposed with a degree of breakdown or radical change in the social order. Much of cyberpunk is rooted in the New Wave science fiction movement of the 1960s and 1970s, when writers like Philip K. Dick, Roger Zelazny, John Brunner, J. G. Ballard, Philip José Farmer and Harlan Ellison examined the impact of drug culture, technology, and the sexual revolution while avoiding the utopian tendencies of earlier science fiction.

Science fiction Genre of speculative fiction

Science fiction is a genre of speculative fiction that typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life. It has been called the "literature of ideas", and often explores the potential consequences of scientific, social, and technological innovations.

Science fiction films This is a list of science fiction films organized chronologically. These films have been released to a cinema audience by the commercial film industry and are widely distributed with reviews by reputable critics. This includes silent film–era releases, serial films, and feature-length films. All of the films include core elements of science fiction, but can cross into other genres such as drama, mystery, action, horror, fantasy, and comedy.

Toho Japanese film production company

Toho Co., Ltd. is a Japanese film, theater production, and distribution company. It has its headquarters in Yūrakuchō, Chiyoda, Tokyo, Tokyo and is one of the core companies of the Hankyu Hanshin Toho Group. Outside Japan, it is best known as the producer and distributor of many kaiju and tokusatsu films, the Chouseishin tokusatsu superhero television franchise, the films of Akira Kurosawa, and the anime films of Studio Ghibli, TMS Entertainment and OLM, Inc.. Other famous directors, including Yasujirō Ozu, Kenji Mizoguchi, Masaki Kobayashi, and Mikio Naruse, also directed films for Toho.

Blood type classification of blood

A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Some of these antigens are also present on the surface of other types of cells of various tissues. Several of these red blood cell surface antigens can stem from one allele and collectively form a blood group system.

Microarray a small-scale two-dimensional array of samples on a solid support

A microarray is a multiplex lab-on-a-chip. It is a two-dimensional array on a solid substrate—usually a glass slide or silicon thin-film cell—that assays (tests) large amounts of biological material using high-throughput screening miniaturized, multiplexed and parallel processing and detection methods. The concept and methodology of microarrays was first introduced and illustrated in antibody microarrays by Tse Wen Chang in 1983 in a scientific publication and a series of patents. The "gene chip" industry started to grow significantly after the 1995 Science Paper by the Ron Davis and Pat Brown labs at Stanford University. With the establishment of companies, such as Affymetrix, Agilent, Applied Microarrays, Arrayjet, Illumina, and others, the technology of DNA microarrays has become the most sophisticated and the most widely used, while the use of protein, peptide and carbohydrate microarrays is expanding.

Western blot analytical technique used in molecular biology

The western blot, or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract.

Science fiction film Film genre

Science fiction film is a genre that uses speculative, fictional science-based depictions of phenomena that are not fully accepted by mainstream science, such as extraterrestrial lifeforms, alien worlds, extrasensory perception and time travel, along with futuristic elements such as spacecraft, robots, cyborgs, interstellar travel or other technologies. Science fiction films have often been used to focus on political or social issues, and to explore philosophical issues like the human condition. In many cases, tropes derived from written science fiction may be used by filmmakers ignorant of or at best indifferent to the standards of scientific plausibility and plot logic to which written science fiction is traditionally held.

Monoclonal antibody Monospecific antibody that is made by identical immune cells that are all clones of a unique parent cell

Monoclonal antibodies are antibodies that are made by identical immune cells that are all clones of a unique parent cell. Monoclonal antibodies can have monovalent affinity, in that they bind to the same epitope. In contrast, polyclonal antibodies bind to multiple epitopes and are usually made by several different plasma cell lineages. Bispecific monoclonal antibodies can also be engineered, by increasing the therapeutic targets of one single monoclonal antibody to two epitopes.

Serology is the scientific study of serum and other body fluids. In practice, the term usually refers to the diagnostic identification of antibodies in the serum. Such antibodies are typically formed in response to an infection, against other foreign proteins, or to one's own proteins.

César Milstein, CH, FRS was an Argentine biochemist in the field of antibody research. Milstein shared the Nobel Prize in Physiology or Medicine in 1984 with Niels Kaj Jerne and Georges J. F. Köhler.

Space Western Science-fiction subgenre that uses the themes and tropes of Westerns within science-fiction stories

Space Western is a subgenre of soft science fiction which uses the themes and tropes of Westerns within science-fiction stories. Subtle influences may include exploration of new, lawless frontiers, while more overt influences may feature literal cowboys in outer space who use rayguns and ride robotic horses. Although initially popular, a strong backlash against perceived hack writing caused the genre to become a subtler influence until the 1980s, when it regained popularity. A further critical reappraisal occurred in the 2000s with Firefly.

Antibody is a 2002 science fiction thriller film directed and edited by Christian McIntire that debuted as a Sci Fi Pictures TV-movie on the Sci Fi Channel on February 8, 2003.

Space opera Subgenre of science fiction

Space opera is a subgenre of science fiction that emphasizes space warfare, melodramatic adventure, interplanetary battles, chivalric romance, and risk-taking. Set mainly or entirely in outer space, it usually involves conflict between opponents possessing advanced abilities, futuristic weapons, and other sophisticated technology. The term has no relation to music, as in a traditional opera, but is instead a play on the terms "soap opera", a melodramatic television series, and "horse opera", which was coined during the 1930s to indicate a clichéd and formulaic Western movie. Space operas emerged in the 1930s and continue to be produced in literature, film, comics, television, and video games.

Saturn Awards Award

The Saturn Awards are American awards presented annually by the Academy of Science Fiction, Fantasy and Horror Films; they were initially created to honor science fiction, fantasy, and horror on film, but have since grown to reward other films belonging to genre fiction, as well as films on television and home media releases.
