Immunity: protection against infectious disease ensured by the immune response generated by i(cid:373)(cid:373)u(cid:374)izatio(cid:374) or pre(cid:448)ious i(cid:374)fe(cid:272)tio(cid:374) (cid:894)body"s a(cid:271)ility to resist a(cid:374)d fight i(cid:374)fe(cid:272)tio(cid:374)(cid:895, 2 types of immunity, non-specific (innate, specific (adaptive, acquired) Iron-binding proteins: bind iron that is necessary for bacterial growth, some bacteria require iron for growth (ex. Specific immunity: humoral and cell-mediated (cmi, extremely specific; targeting one type of pathogen. Adaptive: directed against on type of invader, dependent on past exposure. Humoral immunity (b-cells: circulating antibodies, antibody: protein that binds specifically to a substance (antigen) Anything that enters the body/ most are protein in nature/ antibody & antigen interactions. 5 y-shaped molecules for even more efficient recognizing of antigens: e hypersensitivity (allergies) and defends against parasites (not as useful, d role in unknown. Immunization: getting the same effects of the 2ndary response. 3-5 injections of the antigen are given until the antibody level reaches a maximum.
