herkistymisprosessi
Herkistymisprosessi, also known as sensitization, is a biological process where an organism becomes increasingly responsive to a particular stimulus after repeated exposure. This heightened responsiveness can manifest in various ways depending on the context. In immunology, it refers to the development of an allergic reaction. Initially, a person may be exposed to an allergen, such as pollen or a food protein, without any adverse effects. However, with subsequent exposures, the immune system may become sensitized, producing antibodies like IgE. Upon re-exposure, these antibodies trigger the release of histamine and other inflammatory mediators, leading to allergic symptoms like itching, swelling, or respiratory distress.
Beyond allergies, herkistymisprosessi can occur in other biological systems. For instance, in the nervous system, repeated
