Specific Cellular Defence
HIV
Attacks and destroys T cells
Lymphocytes
White blood cells
Recognise antigens on invading pathogens
Antigens are proteins found on cells surface, which can trigger immune response
Lymphocytes detect foreign pathogens and produce antigens
T cells
Destroy infected body cells by recognising antigens an inducing apoptosis
Apoptosis is programmed cells death
Failure of immune system regulation leads to responding to own cells - autoimmune disease
B cells
Antibodies against antigens, resulting in pathogen destruction
Can respond to antigens on harmless substances
Hypersensitive response is an allergic reaction
Memory cells
Some cloned versions of lymphocytes survive as memory cells
When a second exposure to the same antigen occurs, memory cells divide rapidly and in greater numbers
They destroy invading pathogens and prevents symptoms
Phagocytes
Recognise pathogens and destroy them by Phagocytosis
Release cytokines to site of infection
