Th17 and Treg cells were discovered much more recently.
For those with a confirmed autoimmune condition, the Th1 Th2 test is possibly the most important test.The test points out imbalances in the immune system by looking at cytokines, proteins that the immune system relies on to communicate. Equally impressive as upregulation in TH1/interferon markers (IFNG and CXCL10/CXCL9) were those noted in TH2 (IL13, CCL18, CCL26, thymic stromal lymphopoietin, and periostin), TH9/IL-9, IL-23 (p40 and p19), and IL-16 mediators (all P < .05). Th1 Th2 Th17 Dominance Test | Advanced. Thus, Th1 and Th2 cells are both self-stimulating and inhibitory to the other cell type, meaning that once a population of naive T helper cells is pushed in the direction of differentiating into Th1 or Th2 cells, the relative ratio of Th1 to Th2 cytokine production can remain tipped in one direction.This phenomenon is referred to as the Th1/Th2 balance, and imbalances of Th1/Th2 cell populations are associated with certain diseases: Th2 cytokine expression patterns tend to promote allergic hypersensitivities leading to asthma, hay fever, and eczema, while Th1 cytokine expression patterns are typically associate with chronic inflammation, tissue injury and auto-immune disorders such as lupus.
IL-17 and Th17 Cells. The Th2-type cytokines include interleukins 4, 5, and 13, which are associated with the promotion of IgE and eosinophilic responses in atopy, and also interleukin-10, which has more of an anti-inflammatory response.
Different T helper cells support unique effector functions via distinct cytokine expression profiles and share a common naive CD4+ T cell progenitor. Today, the most commonly studied T helper cells are Th1, Th2, Th17 and Treg.
The BD™ CBA BD CBA Human Th1/Th2/Th17 Cytokine Kit can be used to measure Interleukin-2 (IL-2), Interleukin-4 (IL-4), Interleukin-6 (IL-6), Interleukin-10 (IL-10), Tumor Necrosis Factor (TNF), Interferon-γ (IFN-γ), and Interleukin-17A (IL-17A) protein levels in a single sample.
Rao A, Avni O. Molecular aspects of T-cell differentiation. Th1 and Th2 Cells: Different Patterns of Lymphokine Secretion Lead to Different Functional Properties. Th17 gets it name by the associated interleukin. Th1 (Type 1) and Th2 (Type2), were characterized during the late 1980s.

1989;7:145-73. The antibodies are spotted on nitrocellulose membrane solid supports and are handled in a very similar manner to Western blots.All C-Series arrays work on the sandwich ELISA principle, utilizing a matched pair of antibodies: an immobilized capture antibody and a corresponding biotinylated detection antibody.
About this topic This topic describes the contents of the Human Th1/ Th2/Th17 Cytokine Kit. Th17 cells are pro-inflammatory and are thought to be involved in the immune response to fungal and certain bacterial infections, as well as being associated with inflammation and airway hyper-responsiveness in asthma and several autoimmune diseases, including inflammatory bowel disease, rheumatoid arthritis, multiple sclerosis, and asthma.The Quantibody arrays are quantitative multiplex ELISA arrays featuring fluorescent detection. Th17 cells are a unique set of T helper cells characterized by the production of IL-17 (also known as IL-17A), IL-17F, and many other inflammatory cytokines. Th17 and Treg cells were discovered much more recently. Th1 cells express high levels of IFNγ and TGFβ1, enhancing cellular immune responses by increasing bacteriocidal activity in macrophages and the proliferation of cytotoxic CD8+ T cells.
