Inmune System - Coggle Diagram
Inmune System
Macrophages
funtions
critical for innate immunity
phagocytosis
the detection of bacteria
and destruction of bacteria
normal tissue development
cell growth
homeostasis
repair of damaged tissue.
effector cells of the innate immune system
specialised cells involved in
T-cells
type of lymphocyte
T cells circulate around the body
until they encounter their specific antigen
funtions
can also be responsible for inflammatory or autoimmune diseases.
They maintain immune homeostasis in humans
lyfe period
Later in life
the functionality of T cells decreases
dysregulation of the immune system
dysregulation of associated pathologies.
In adulthood
maintain homeostasis and immunoregulation of repeat
chronically encountered antigens.
infancy
develop inmunity towards common pathogens or antigens
T cell activation and mechanism
originate in the bone marrow
are matured in the thymus
not activated until they find their specific antigen
need secondary signals to become fully activated
types
helper
they sense an infection
activate other immune cells to fight it
regulatory
a specialized subpopulation of T cells
hat act to suppress immune response
maintaining homeostasis and self-tolerance
cytotoxic
can kill certain cells
including foreign cells
cancer cells
cells infected with a virus
B cells
lineage of lymphocytes (white blood cell)
makes antibodies
produced in response to antigens.
They bind to specific antigens
so the pathogen can be eliminated from the body
alerting other white cells
direct neutralization
develop from stem cells in the bone marrow.
