types of haematopoietic stem cells Flashcards
1
Q
monocytes
A
- circulating precursor to dendritic cells and macrophages
2
Q
macrophages
A
- tissue resident around the body
- phagocytic and antigen presenting
3
Q
dendritic cells
A
- differentiate in the tissue
- phagocitic and antigen presenting
- travel to the lymph nodes to activate T cells
4
Q
neutrophil
A
- circulating cell
- highly phagocytic granulocyte
5
Q
eosinophil
A
- circulating cell
- responds to IgE
- can degranulate to remove parasites
6
Q
basophil
A
- circulating granulocytes in very low numbers
7
Q
mast cells
A
- tissue resident
- source of cytokines and can degranulate
8
Q
T lymphocytes
A
- helper and cytotoxic
- recirculate through lymph nodes
activated by dendritic cells
9
Q
natural killer cells
A
- innate immune cells
- kill infected cells using their granule contents (granzyme and perforin)
10
Q
b lymphocytes
A
- produce antibodies as a defence
- activated by T cells to produce high affinity antibodies
- become antibody secreting plasma cells
11
Q
what are the myeloid cells
A
- monocytes
- macrophages
- neutrophils
- basophils
- eosinophils
- erythrocytes
- platelets
12
Q
what are the lymphoid cells/ lymphocytes
A
- t cells
- b cells
- natural killer cells
- (dendritic cells)
13
Q
what are the granulocytes
A
- neutrophils
- eosinophil
- basophil
- mast cells
