Key Concepts

Immunoglobulins

Immunoglobulins, or antibodies, are glycoproteins produced by plasma cells that play a key role in the immune response. They come in different classes, each with specific structures and functions, such as neutralizing pathogens, facilitating phagocytosis, and triggering the complement system. Understanding the distinctions among these classes is fundamental in immunology.

Transplacental Transfer

Transplacental transfer is the process by which certain antibodies, specifically IgG, are transported from the mother to the fetus through the placenta. This transfer is crucial for providing passive immunity to the newborn, offering protection against infections during early life until the infant's own immune system matures.
