Identify the exposed antigen and complementary antibody, trace activation or binding and connect the interaction to opsonisation, agglutination or cell destruction.
There are four types of immunity.
Natural active immunity can develop when a person is infected with a virus.
Describe the role of macrophages in the development of natural active immunity to a virus, following infection.
A description that includes the following points:
- engulf the virus / phagocytosis of the virus (1)
- digestion of the virus (1)
- antigen presentation to \{T helper / CD4\} \{cells / lymphocytes\} (1)
ACCEPT pathogen, if in context of virus reference to a macrophage being a phagocyte, if in context of viruses
DO NOT ACCEPT kills the virus
ACCEPT macrophage is an \{antigen presenting cell / APC\} to T helper cells DO NOT ACCEPT to T killer cells
