  • neutralize
  • Antibodies can simply bind to IFN-beta or glatiramer acetate (binding Ab, or BAb) with no subsequent effect on function, or they can block or neutralize (neutralizing Ab, or NAb) their biological activity. (wikipedia.org)
  • Mark S. Freedman, MD, MSc This difference is what gives neutralizing antibodies the ability to fight viruses which attack the immune system, since they can neutralize function without a need for white blood cells (excluding production) Broadly-neutralizing antibodies (bNAbs) affect multiple strains of a particular virus. (wikipedia.org)
  • 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. (wikipedia.org)
  • 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 (for example, by blocking a part of a microbe that is essential for its invasion and survival). (wikipedia.org)
  • bind
  • For any given antigen, at least one of these side chains would bind, stimulating the cell to produce more of the same type, which would then be liberated into the blood stream as antibodies. (wikipedia.org)
  • According to Ehrlich, an antibody could be considered an irregularly shaped, microscopic, three-dimensional label that would bind to a specific antigen but not to the other cells of the organism. (wikipedia.org)
  • Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. (wikipedia.org)
  • The ability of an antibody to bind to its corresponding FcR is further modulated by the structure of the glycan(s) present at conserved sites within its Fc region. (wikipedia.org)
  • The ability of antibodies to bind to FcRs helps to direct the appropriate immune response for each different type of foreign object they encounter. (wikipedia.org)
  • immune system
  • Giving patients a modified gp120 that contains little more than the epitope that both antibodies target could act to "prime" the immune system, followed by a booster that contains trimer spikes in the most natural configuration possible. (wikipedia.org)
  • Exotoxins are susceptible to antibodies produced by the immune system, but many exotoxins are so toxic that they may be fatal to the host before the immune system has a chance to mount defenses against them. (wikipedia.org)
  • An antibody is a protein that is produced in B cells and used by the immune system of humans and other vertebrate animals to identify a specific foreign object like a bacterium or a virus. (wikipedia.org)
  • These non-human antibodies are recognized as foreign by the human immune system and may be rapidly cleared from the body, provoke an allergic reaction, or both. (wikipedia.org)
  • The ability of an antibody to communicate with the other components of the immune system is mediated via its Fc region (located at the base of the "Y"), which contains a conserved glycosylation site involved in these interactions. (wikipedia.org)
  • The production of antibodies is the main function of the humoral immune system. (wikipedia.org)
  • Antibodies are secreted by B cells of the adaptive immune system, mostly by differentiated B cells called plasma cells. (wikipedia.org)
  • Humoral
  • Humoral immunity or humoural immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies , complement proteins , and certain antimicrobial peptides . (wikipedia.org)
  • Humoral immunity refers to antibody production and the accessory processes that accompany it, including: Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation. (wikipedia.org)
  • Passive immunity is the transfer of active humoral immunity in the form of ready-made antibodies. (wikipedia.org)
  • Humans
  • A consortium of animal-welfare groups has funded research to develop a product it says could lead to more effective treatment of infectious diphtheria in humans while sparing thousands of horses now being bled to produce antitoxins. (foxnews.com)
  • Antitoxins made from horses aren't the best for humans,' Brown said. (foxnews.com)
  • Antitoxins are made within organisms, but can be injected into other organisms, including humans. (wikipedia.org)
  • In humans, maternal antibodies (MatAb) are passed through the placenta to the fetus by an FcRn receptor on placental cells. (wikipedia.org)
  • Only a few other species besides humans transfer maternal antibodies before birth, including primates and lagomorphs (which includes rabbits and hares). (wikipedia.org)
  • soluble
  • Antibodies can occur in two physical forms, a soluble form that is secreted from the cell to be free in the blood plasma, and a membrane-bound form that is attached to the surface of a B cell and is referred to as the B-cell receptor (BCR). (wikipedia.org)
  • bacterial
  • The worldwide consortium of PETA groups awarded 134,000 euros (about $142,000) to Technical University Braunschweig in Germany to pioneer a new treatment for diphtheria, a bacterial infection. (foxnews.com)
  • IgG antibodies protects against bacterial and viral infections in fetuses. (wikipedia.org)
  • Ehrlich's
  • Ehrlich's theory can be summarised with the following tenets: Antibodies are produced by white blood cells normally and they act as side chains (receptors) on the cell membrane. (wikipedia.org)
  • Dr. Ehrlich's Magic Bullet, a 1940 film Diphtheria Syphilis Witebsky, Ernest (1954). (wikipedia.org)
  • Despite Paul Ehrlich's demonstration of the effectiveness of diphtheria antitoxin in the 1890s, the treatment remained slowly adopted on wider scale and diphtheria deaths in children continued to rise well into early decades of the 1900s. (wikipedia.org)
  • concentration
  • The strongest associations suggested a decrease in the antibody concentration by about 20% for each doubling in PCB exposure. (nih.gov)
  • Tdap
  • Prelicensure studies demonstrated safety and efficacy, inferred through immunogenicity, against tetanus, diphtheria, and pertussis when Tdap was administered as a single booster dose to adults. (cdc.gov)
  • Behring's
  • From Behring's work, Ehrlich understood that antibodies produced in the blood could attack invading pathogens without any harmful effect on the body. (wikipedia.org)
  • equine
  • Stocks of the equine antitoxin have become increasingly difficult to locate, and those who receive it sometimes experience reactions similar to anaphylactic shock, Hust said. (foxnews.com)
  • 2017
  • In April 2017, at the WHO's 64th Consultation on International Nonproprietary Names for Pharmaceutical Substances, it was decided to drop the source substem and from that meeting onwards, it is no longer used in new antibody names. (wikipedia.org)
  • mutations
  • Most mutations that shape bNAbs take place at the tips of the Y-shaped antibody molecules, which have loops to ensnare viral epitopes. (wikipedia.org)
  • This antibody attached to a "conserved" portion of gp120 that outlasts many of its mutations, affecting 17/24 tested strains at low doses. (wikipedia.org)
  • bNAbs evolve over years, accumulating some three times as many mutations as other antibodies. (wikipedia.org)
  • The large and diverse population of antibody paratope is generated by random recombination events of a set of gene segments that encode different antigen-binding sites (or paratopes), followed by random mutations in this area of the antibody gene, which create further diversity. (wikipedia.org)
  • infection
  • They individually probed 30,000 of one woman's antibody-producing B cells and isolated two that were able to stop more than 70% of 162 divergent HIV strains from establishing an infection. (wikipedia.org)
  • However, it is less certain whether the detection of antibodies in cerebrospinal fluid (c.s.f.) of infants indicates congenital infection of the central nervous system, because the origins of such antibodies have not been established. (biomedsearch.com)
