Researchers obtain a pure solution of antibodies that bind specifically to the cadherins (linking proteins) of the desmosomes of epithelial cells of a mouse. As a follow up of their previous experiment, they take a tube of individual muscle cells from a chicken and add antibodies to the tube. What is the predicted outcome of this second experiment? A. The antibodies will bind to the chicken muscle cells, so the cells will adhere to each other B. The antibodies will bind to the chicken muscle cells, so the muscle cells will not adhere to each other C. The antibodies will not bind to the chicken muscle cells, so the cells will adhere to each other D. The antibodies will not bind to the chicken muscle cells, so the cells will not adhere to each other

Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.
