PASSIVE ANTIBODY TRANSFERS Meaning and
Definition
-
Passive Antibody Transfer refers to the introduction of preformed antibodies into an individual's body to provide immediate protection against a particular pathogen or toxin. This process involves the transfer of pre-existing antibodies produced by another organism into a recipient to bolster the recipient's immune response temporarily.
Passive Antibody Transfer can occur naturally, such as when a mother passes antibodies to her fetus through the placenta during pregnancy or through breast milk during breastfeeding. In a medical context, it is achieved by administering purified antibodies derived from the serum or plasma of another individual or animal species that has previously been exposed to the specific pathogen or toxin of interest.
The transferred antibodies bind to the antigens present on the pathogen or toxin, preventing their attachment to the recipient's cells and neutralizing their harmful effects. This process provides immediate protection against the pathogen without the recipient having to produce their own antibodies, which can take time and may not occur efficiently in some cases.
Passive Antibody Transfer is commonly used in the treatment of infectious diseases and toxin-mediated conditions. It is often employed as a supportive therapy for individuals with weakened immune systems or individuals who have been exposed to a pathogen but have not yet developed their own immune response. Additionally, it can serve as a preventive measure in some cases, such as the administration of antibodies following exposure to a particular virus or toxin to prevent the development of disease symptoms.
