- Neutrophil
- Monocyte
- Dendritic cell
Term
G-CSF
Definition
- CFC-NM -> neutrophil
Term
M-CSF
Definition
- CFC-NM -> Monoctye
Term
Flt3-ligand

IL 12 in THx repsone?

Which Thelper response?
Which cell type secretes it?
Function?
Definition
-Th1 pathway

- secreted by APC

- commit Th0 -> Th1
Term
IL 18 in THx repsone?

Which Thelper response?
Which cell type secretes it?
Function?
Definition
- Th1 pathway

- APC secretes it

- works in concert with IL12, enhancing it's effect of committing Th0->Th1
Term
INF-γ in THx repsone?

Which Thelper response?
Which cell type secretes it?
Function?
Definition
- Th1 pathway

- T helper secretes it

- activates macrophages
- supresses Th2 or Th17 response
Term
IL-2 in THx repsone?

Which Thelper response?
Which cell type secretes it?
Function?
Definition
- Th1 pathway

- Th1 cell secretes it

- Helps Th1 cell proliferation and growth
Term
IL 21 in THx repsone?

Which Thelper response?
Which cell type secretes it?
Function?
Definition
In Th1 pathway, secreted by Th1 cell
- activates CD8 cytotoxicity

In Th2 pathway (absence of INF-y) secreted by Th2 committed cell
- stimulates B cell proliferation
Term
IL 1 - main function
Definition
- increases APC presenation
Term
IL-6 main function
Definition
- fever in concert with IL6
- also activates B cells
Term
IL 8 main function
Definition
- recruitment of neutrophils
Term
TNF-α - 3 main functions as proinflammatory cytokine
Definition
- macrophage recruitment
- endothelial cell homing and adheison
- growth of vasculature
Term
IL-10 in THx repsone?

Which Thelper response?
Which cell type secretes it?
Function?
Definition
-Th2 pathway

- secreted by Th2 cell

- potent supressor of Th1/TIMMI response
Term
Leptin
Definition
proinflammatory cytokine released by adipocytes

- increases TNF-alpha, IL1, IL6
Term
Visfatin
Definition
Proinflammatory cytokine produced by adiopocytes, also pro angiogenic
Term
Adiponectin
Definition
anti-inflamatory cytokine produced by adipocytes

- decreases TNF-alpha
Term
MAC1
Definition
Macrophage inhibitory cytokine - produced by adipocytes and is anti-inflammatory

- major stimulator of adiponectin
Term
SFRP
Definition
anti-inflammatory cytokine of adipocytes
Term
Osteopontin
Definition
- proinflammatory macrophage derived cytokine that acts in adipose tissue
- strongly chemotactic for monocytes and macrophages
Term
Resistan
Definition

- proinflammatory macrophage derived cytokine

- direct antagonist of adiponectin and promotes TNF-alph and IL 6 production
