Immune response:
Specific response to the detection of pathogens in he body
Involves B Cells and T cells (white blood cells with specialised receptors on their plasma membrane)
Produces antibodies - they neutralise the foreign antigens
Provides long-term protection from disease
Produces immunological memory through the reease of memory cells

Starting the Response
T and B lymphocytes must detect the foreign antigens on the incading pathogen
Lymphocytes carry receptor molecule on their membranes, they have a complimentary shape of the antigens on proteins
Once T or B lymphocytes detect the antigens they immune response can begin

Very few correct T and B lymphocytes - takes a while to find the antigens
Cells that are attacked  by the pathogen will display…
