What IL is responsible for the differentiation of HCS–> CLP?
IL-7
What IL is responsible for the differentiation of HCS–> CMP?
IL-3
Which IL activates Mast cells?
IL-12
What cells bridge the innate and adaptive immunity?
Dendritic cells
What is the second exposure to an antigen like?
- Response is larger (more antibodies released)
2. Response is faster
What happens when a lymphocyte is not activated by an antigen?
It will leave the lymphatics and go to the next lymphoid tissue.
Steps of lymphocyte migration
- Enter lymphoid tissue
- Follow cytokine signals
- No activation–> next lymhoid tissue
- Still no activation–> go to the thoracic duct and re-circulate
What colony factors and interleukins do you need to develop a macrophage?
IL1
IL3
IL6
M-CSF
Which of mechanism requires antibodies in order to activate fx/cascade?
Classical compliment pathwat
Anti-inflammatory components
IL-10
TGF-B
What hemopoietic growth factor stimulates the growth of neutrophils?
G-CSF
What hemopoietic growth factor stimulates the growth of macrophages?
M-CSF
What is a chemokine that attracts neutrophils to a site of injury?
IL-8
What leukocyte do you usually find in pus>?
Neutrophils. Neutrophils generally die in the course of the battle.
What causes the healing of tissue?
Macrophages;
Remember, they heal tissue as well.
Clonal selection
occurs in the primary lymphoid organ WITHOUT EXPOSURE to antigen
