Mammalian Immune Response To Parasites Flashcards
The first and second line of defences work against a wide range of parasites, this is described to be what
Non specific
What are T-lymphocytes
Destroys specific infected or damaged cells by apoptosis
Whatever B-lymphocytes
Produce antibodies which are specific to the antigen
What is clonal selection
lymphocytes become amplified by mitosis
Clonal selection creates two cells, what are they
Memory and plasma
What is the first line defence two techniques that work together to prevent many parasites from entering the body fluids
Chemical secretions and physical barriers
What are the three non specific ways to defend parasites
Natural killer cells, immune response and phagocytes
What is immune response
Release of histamine when swelling occurs and can stimulate phagocytes
How do phagocytes work
Engulf and digests
What are natural killer cells
Detected abnormal cell surface proteins and induce apoptosis
What are the specific cellular defences
Lymphocytes and immune surveillance, clonal selection and action of lymphocytes
What are lymphocytes
They are white blood cell which has one type of antigen receptor protein that produces clones
What is immune surveillance
Lymphocytes checking for specific antigens using receptors on the surface
