Tachyphylaxis is characterized by the rate sensitivity: the response of the system depends on the rate with which a stimulus is presented. To be specific, a high-intensity prolonged stimulus or often-repeated stimulus may bring about a diminished response also known as desensitization.
In medicine, desensitization is a method to reduce or eliminate an organism's negative reaction to a substance or stimulus. In pharmacology , drug desensitization refers to two related concepts. First, desensitization may be equivalent to drug tolerance and refers to subjects' reactions (positive or negative) to a drug reducing following its ...
Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies (such as insect bites) and asthma. [ 1 ] [ 2 ] Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response.
Homologous desensitization also occurs with cytokine and other types of receptors, such as those of the epidermal growth factor receptor type, but in these cases desensitization is mediated by other types of receptor kinases. [2] Homologous desensitization serves to limit or restrain a cell's responses to stimuli.
Decoding organic vs. conventionally grown. These stickers can offer clues as to how your produce was grown — be it conventional or organic. The easiest way to tell the difference is if the code ...
Homologous desensitization occurs when a receptor decreases its response to an agonist at high concentration. [1] It is a process through which, after prolonged agonist exposure, the receptor is uncoupled from its signaling cascade and thus the cellular effect of receptor activation is attenuated.
A 21-year-old Norwegian woman has become the youngest person to reach the South Pole on skis, solo and without assistance, her team told AFP on Tuesday. Karen Kylleso accomplished the feat ...
