isotypová

Isotypové is a term that appears to be a misspelling or a less common transliteration. The most likely intended term is "isotype," which has several meanings depending on the field of study.

In chemistry and physics, an isotype refers to a nuclide that has the same number of protons and a different number of neutrons in its nucleus. This means that isotopes of an element have the same atomic number but different mass numbers. For example, hydrogen has three common isotopes: protium (one proton, zero neutrons), deuterium (one proton, one neutron), and tritium (one proton, two neutrons). Isotopes of an element exhibit very similar chemical properties because their electron configurations are identical. However, their physical properties, such as mass and nuclear stability, can differ significantly.

In the context of immunology, an isotype refers to a specific class or subclass of antibodies. Antibodies, also known as immunoglobulins, are proteins produced by the immune system to neutralize pathogens. They are classified into different isotypes (IgG, IgM, IgA, IgD, and IgE) based on variations in their heavy chains. Each isotype has distinct structural and functional characteristics that determine its role in the immune response. For instance, IgG is the most abundant antibody in serum and plays a crucial role in long-term immunity, while IgE is primarily involved in allergic reactions.
