Immunoglobuliniche

Immunoglobuliniche is a term that refers to immunoglobulins, which are also known as antibodies. These are Y-shaped proteins produced by the immune system to identify and neutralize foreign substances such as bacteria and viruses. Each antibody is designed to bind to a specific antigen, a unique molecule found on the surface of these foreign invaders. This binding action is crucial for various immune responses, including agglutination, precipitation, and neutralization of toxins.

There are five main classes of immunoglobulins: IgG, IgM, IgA, IgE, and IgD. Each class has a distinct structure and function. IgG is the most abundant in blood and is important for long-term immunity. IgM is the first antibody produced during an infection and is effective at combating bacteria. IgA is found in bodily secretions like saliva and mucus, providing mucosal immunity. IgE is involved in allergic reactions and defense against parasites. IgD is primarily found on the surface of B cells and plays a role in B cell activation. The collective term "immunoglobuliniche" encompasses all these classes and their roles in adaptive immunity.
