Target/Biomarker information

Feline Immunoglobulin G (IgG) stands as a linchpin in the intricate framework of the feline immune system. Structurally, IgG is a glycoprotein characterized by its Y-shaped configuration, comprising two identical heavy chains and two identical light chains, held together by disulfide bonds. Each IgG molecule features antigen-binding regions of extraordinary specificity, finely tuned to recognize and bind to a diverse array of pathogens. The production of IgG antibodies in cats unfolds as a meticulously orchestrated process. When B cells, a subset of white blood cells, encounter antigens—foreign substances or pathogens—they undergo activation. Subsequently, these activated B cells transform into plasma cells, specialized factories dedicated to IgG production. These plasma cells churn out copious amounts of IgG antibodies, which are then released into the bloodstream. Feline IgG antibodies exhibit remarkable versatility and precision. They possess the ability to effectively recognize and bind to a wide spectrum of pathogens, including bacteria, viruses, fungi, and parasites, through their antigen-binding regions. This interaction serves multifaceted functions, from neutralizing the invaders to activating other immune cells, facilitating pathogen clearance, and marking pathogens for destruction. One of the extraordinary attributes of Feline IgG is its role in establishing long-lasting immunity. After an initial encounter with an antigen, memory B cells are generated. These memory B cells "remember" the specific pathogen, enabling the rapid production of IgG antibodies upon subsequent exposure to the same antigen. This mechanism underpins adaptive immunity, allowing cats to mount a swift and effective response upon reencountering a pathogen.
