The original antigenic sin: When the body first encounters an infection it produces effective antibodies against its dominant antigens and thus eliminates the infection. But when it encounters the same infection, at a later evolved stage, with a new dominant antigen, with the original antigen now being recessive, the immune system will still produce the former antibodies against this old "now ...
Original antigenic sin; Vaccine adverse event; Other ways in which antibodies can (unusually) make an infection worse instead of better Blocking antibody, which can be either good or bad, depending on circumstances; Hook effect, most relevant to in vitro tests but known to have some in vivo relevances
This doctrine is known as the original antigenic sin. [21] This phenomenon comes into play particularly in immune responses against influenza , dengue and HIV viruses. [ 25 ] This limitation, however, is not imposed by the phenomenon of polyclonal response, but rather, against it by an immune response that is biased in favor of experienced ...
An illustration that shows how antigens induce the immune system response by interacting with an antibody that matches the molecular structure of an antigen. In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. [1]
Through an immunological phenomenon, known as original antigenic sin, the immune system is not able to adequately respond to the stronger infection, and the secondary infection becomes far more serious. [6]
In Marxian economics and preceding theories, [1] the problem of primitive accumulation (also called previous accumulation, prior accumulation, or original accumulation) of capital concerns the origin of capital and therefore how class distinctions between possessors and non-possessors came to be.
Original antigenic sin, descriptive diagram. en:Original antigenic sin refers to the propensity of the body's immune system to preferentially utilize immunological memory based on a previous infection when a second slightly different version of that foreign entity is encountered.
Depiction of the sin of Adam and Eve (The Garden of Eden with the Fall of Man by Jan Brueghel the Elder and Pieter Paul Rubens). Original sin (Latin: peccatum originale) in Christian theology refers to the condition of sinfulness that all humans share, which is inherited from Adam and Eve due to the Fall, involving the loss of original righteousness and the distortion of the Image of God.
