En esta lección vamos a discutir el proceso de la inmunidad adaptiva.
A particle that has the potential to stimulate an immune response; antigens are basically the identity marker of cells for the immune system to see.
Also known as specific immunity, adaptive immunity is carried out by T & B lymphocytes and reacts to specific antigens of cells; adaptive immunity also produces memory cells to target the same pathogen if we are ever exposed to it again.
Also known as T lymphocytes, T cells carry out a version of specific immunity called cell-mediated immunity or cellular immunity. During cellular immunity the immune response is enhanced by helper T cells and cells are directly attacked by cyotoxic T cells.
Also known as B lymphocytes, B cell carry out a version of specific immunity called humoral immunity. During humoral immunity B cells form into plasma cells that mass produce antibodies to be secreted into our body tissue cavities.
Specific protein markers that are created by the immune system for binding and reacting to specific antigens; antibodies are created by B cells during humoral immunity.
Memory cells are genetically programmed cells that have gone through an initial exposure to a pathogen/antigen that can coordinate a much more specific and rapid response if we are ever exposed to that same pathogen/antigen.
