... by their sheer size. The virus will be unable to dock to a cell and infect it, hindered by the antibody. They can also agglutinate them so the phagocytes
can capture them.
Antibodies that recognize bacteria mark them for ingestion by macrophages. Together with the plasma component complement , ...
Plasma B cells secrete antibodies which effect the destruction of antigens by binding to them and making them easier targets for phagocytes
Memory B cells are formed specific to the antigen(s) encountered during the primary immune response; able to live for a long time, these ...
... by an attenuated response. There are congenital (inborn) and acquired forms of immune deficiency. Chronic granulomatous disease , in which phagocytes
have trouble destroying pathogens, is an example of the former. AIDS ("Acquired Immune Deficiency Syndrome"), an infectious disease , caused by ...
Major histocompatibility complex
... The helper T cells then help to trigger an appropriate immune response which may include localized inflammation and swelling due to recruitment of phagocytes
or may lead to a full-force antibody immune response due to activation of B cells.
MHC evolution and allelic diversity
MHC gene families are ...
... Pseudopods also capture prey phagocytosis . Phagocytosis pseudopods have arisen in a number of different protist groups, but also in some cells ( phagocytes
) in multicellular organisms.
Pseudopods can be classified into several varieties according to their appearance:
