What immunoglobulin is for cats? - briefly
Immunoglobulins in cats, also known as antibodies, are proteins produced by the immune system to identify and neutralize pathogens like viruses and bacteria.
What immunoglobulin is for cats? - in detail
Immunoglobulins, commonly known as antibodies, are essential components of the feline immune system, produced by B cells in response to pathogens such as viruses, bacteria, or other foreign substances. In cats, immunoglobulins are classified into several types, including IgG, IgM, IgA, and IgE, each with distinct functions. IgG is the most abundant immunoglobulin in feline serum and provides long-term immunity by neutralizing pathogens and facilitating their removal by immune cells. IgM is the first antibody produced during an initial immune response, acting as a rapid but short-lived defense mechanism. IgA is primarily found in mucosal surfaces, such as the respiratory and gastrointestinal tracts, where it prevents pathogens from entering the body. IgE is involved in allergic reactions and defense against parasites. In veterinary medicine, immunoglobulins are often administered to cats as part of passive immunotherapy, particularly in cases of infectious diseases like feline panleukopenia or feline herpesvirus, where they provide immediate but temporary protection. Additionally, maternal immunoglobulins are transferred to kittens through colostrum, offering crucial immune support during the early stages of life. Understanding the role of immunoglobulins in cats is vital for developing effective vaccines, treatments, and preventive strategies to enhance feline health and combat infectious diseases.
