QUIZ QUESTION: In an example of inflammation-mediated antibody damage to cells, Ig binds to self antigen on epithelial cells → complement binds Ig and is activated → pro inflammatory fragments of complement proteins are produced → the fragments bind to vessel walls → neutrophils move out of vessels → neutrophils bind to ____________ via receptors → neutrophils are triggered to release granules that damage cells. 1. complement proteins 2. Ig Fc portion 3. infected cells 4. sel...

What cells participate in the process of antibody production? Where are they located? - ANS naive B cells produce the plasma cells, the plasma cells then make the antibodies plasma cells are found in the bone marrow B cell sits around largely in lymph nodes? In what ways do the complement pathways and humoral immunity interact? - ANS the classical pathway in complement is activated by antibody-antigen dependent binding Where are lymphoid cells produced? - ANS bone...

neutralization antibodies block spike proteins and prevent viruses from binding to cell receptors agglutination - antibodies "stick bacteria together" - large clump is easier for phagocyte to recognize opsonization - "eat me" tags - C3b and antibodies - enhance phagocytosis complement activation classical pathway initiated by antibody binding ag for destruction - NK cells kill bacteria/infected cell - ADCC (antibody dependent cellular cytotoxicity) - antibodies serve as re...

Activator proteins - A DNA-binding proteins that recruit transcriptional machinery Affinity chromatography - A method of separating biochemical mixtures based on a highly specific interaction such as that between antigen and antibody, enzyme and substrate, or receptor and ligand Alternative pathway of complement activation - C3b binds directly to cell surface C5b-9 forms the MAC Anion exchange chromatography - Negative charges bind to the beads, so positive charges will elute sooner. Anti...
