BIO 11 Lecture Notes - Lecture 26: Adaptive Immune System, Immunoglobulin M, Fetus
Document Summary
Antibody, mediated immunity - b cells, because responsible for antibody production. Starts the same as cell mediated - the more detailed the antigen the more likely antibodies will mediate the immunity. If helper t cell determines it is antibody mediated side - calls upon immature b cell. Innate immunity which is genetically determined; handed down from genes. Acquired immunity not have at birth, acquire over lifetime through vaccinations or exposure to virus. Passive immunity given to you through transfer of antibodies through placenta and fetus - before birth. Igm -> true first round of released immunoglobin, not in standard y shape, unit of 5 standard y shaped antibodies that have been linked together at the bottom end to form a star. Immediately released after the antigen arrives, has the ability to agglutinate or cluster together the antigen to see if they can kill it off faster, not mass produced, only. 24 hours when antigen first arrives, begin mass killing process.
