What are Th1 cytokines?
Table of Contents
What are Th1 cytokines?
Th1-type cytokines tend to produce the proinflammatory responses responsible for killing intracellular parasites and for perpetuating autoimmune responses. Interferon gamma is the main Th1 cytokine.
What are the two types of cytokines?
Cytokines include Interleukins, Lymphokines, Monokines, Interferons (IFN), colony stimulating factors (CSF), Chemokines and a variety of other proteins. Type-1 cytokines are cytokines produced by Th1 T-helper cells while Type-2 cytokines are those produced by Th2 T-helper cells.
What are Th1 and Th2 cytokines?
TH1 immune response refers to the cytokine-mediated immune response generated by TH1 cells against intracellular parasites such as bacteria and virus, while TH2 immune response refers to the cytokine-mediated immune response generated by TH2 cells against large, extracellular parasites such as helminths.
What cytokine activates Th1?
The two cytokines that play a critical role in Th1 differentiation are IFNγ and IL-12. IL-12 secreted by APCs upon T cell engagement drives differentiation into Th1 effector cells through the activation of STAT4 transcription factor.
What is type 1 and type 2 inflammation?
Overall, a Th1 type response (or type 1 inflammatory response) is better at producing an immune response that is effective at targeting viruses and bacteria. 3 In contrast, a Th2 type response is better at eliminating certain parasites, like tapeworms or nematodes.
What is difference between Th1 and Th2?
Definition. TH1 immune response refers to the cytokine-mediated immune response generated by TH1 cells against intracellular parasites such as bacteria and virus, while TH2 immune response refers to the cytokine-mediated immune response generated by TH2 cells against large, extracellular parasites such as helminths.
What cytokines do Th1 cells secrete?
Th1 cells are most often defined by their production of IL-2 and IFN-γ but have been reported to produce a number of cytokines including: TNF, lymphotoxin, and granulocyte-macrophage colony-stimulating factor (GM-CSF).
What cytokines do Th1 and Th2 produce?
1. Th1 and Th2 Cells
| Differences | Th1 | Th2 |
|---|---|---|
| Secreted cytokines | IFN-γ，IL-2, IL-3, TNF-α, TNF-β | IL-4, IL-10, IL-5, IL-9, IL-13 |
| Characteristic cytokines | IFN-γ | IL-4 |
| Adjustment factor | IFN-γ, IL-12 | IL-4, IL-13, IL-5 |
What is Type 1 and Type 2 immunity?
Type 1 immunity is critical for defence against many intracellular pathogens, bacteria, viruses and other microorganisms. By contrast, type 2 immunity promotes immunity against extracellular parasites and helminths, helps to maintain metabolic homeostasis and regulates tissue repair following injury.
What is Th1 and Th2?
Th1 and Th2 cells play an important role in immunity. Th1 cells stimulate cellular immune response, participate in the inhibition of macrophage activation and stimulate B cells to produce IgM, IgG1. Th2 stimulates humoral immune response, promotes B cell proliferation and induces antibody production (IL-4).
