isotypens

Isotypens, also known as isotypes, are a group of immunoglobulins that share the same variable region but differ in their constant regions. These immunoglobulins are produced by B cells and play a crucial role in the immune system's response to infections. Isotypens are classified based on their constant regions, which determine their function and specificity. The most common isotypes include IgG, IgA, IgM, IgE, and IgD. Each isotype has distinct properties and functions, such as IgG's role in neutralizing pathogens and IgE's involvement in allergic reactions. The study of isotypens is essential for understanding immune responses, diagnosing diseases, and developing immunotherapies.
