The term "cytokine" is derived from a combination of two Greek words - "cyto" meaning cell and "kinos" meaning movement. Cytokines encompasses a wide range of low-weight molecular proteins (~5-20 kDa) that play different roles in regulating various aspects of the immune response. they are released by cells and affect the behavior of other cells, and sometimes the releasing cell itself.The ELISA (enzyme-linked immunosorbent assay ) is a useful tool to study the function of cytokines.Meretciel provide ELISA kits for R&D.
According function, cytokines include chemokines, interferons, interleukins, lymphokines, tumour necrosis factor and the adipokines but generally not hormones or growth factors.
Cytokines include chemokines, interferons (IFN), interluekins (IL), lymphokines, and tumour necrosis factors (TNF). They are produced by many types of cells, including immune cells such as macrophages, B lymphocytes, T lymphocytes, mast cells, endothelial cells, fibroblasts, and various stomal cells. IL-1, IL-6, and TNF-alpha produces local vascular effects by increasing the expression of adhesion molecules and promoting vascular permeability. Cytokines also have the ability of produce systemic effects. They stimulate production of acute phase proteins in the liver through direct action and through the release of cortisol. They can also induce fever by acting on the hypothalamus in the brain. In addition, IL-6, and TNF-alpha can travel to bone marrow to increase the synthesis of colony-stimulating factor. This leads to increased production of white blood cells.

Why would the immune system not be able to function with cytokines?
Cytokines play an important role in fighting some forms of bacterial infections. The cytokines basically tell the immune system that an infection is there so that the immune system can handle it.
What are the regulators of immune response?
cytokines
What are cytokines Explain their structure function?
Cytokines are small proteins that act as signaling molecules in the immune system, regulating cell communication and behavior. They play a key role in inflammation, immune responses, and other processes. Cytokines can be produced by various cells, such as immune cells, and can have diverse functions based on their type and target cells.
Are cytokines a chemical?
Cytokines encompasses a wide range of low-weight molecular proteins (~5-20 kDa).They are released by cells,so produced by organism and not by chemical reaction.Meretciel offer high quality ELISA kits for R&D,can use to detect the concentration of Cytokines. But chemical are usually produced by or used in a reaction involving changes in atoms or molecules. So Cytokines are biologicals not chemicals.
Which cytokines act as a signal between leukocytes?
interleukines
What do studies of cytokines show?
Studies of cytokines show that psychological factors such as stress depress the immune system, but that deviations in the immune system can also trigger psychological and behavioral changes.
What are the uses of cytokines?
Cytokines are proteins that play a key role in cell signaling and immune response regulation. They are involved in various functions such as inflammation, cell growth, and differentiation. Cytokines also play a role in communication between different cells of the immune system to coordinate an effective immune response against pathogens.
How do cytokines help the human immune system?
Cytokines which are released or produced by the immune system influence the behavior or action of the brain assisting it to function in curing illness like depression and mental illness. The immune system is made to function more effectively in fighting most body diseases with the help of these cytokines.
Which cytokines have antiviral activity?
IFN alpha & IFN betha
What act as intracellular signals to begin the immune response?
Cytokines
What are Th1 cytokines?
Th1 cytokines are a group of cytokines produced by T helper 1 (Th1) cells in the immune system. They include interleukin-2 (IL-2), interferon-gamma (IFN-γ), and tumor necrosis factor-alpha (TNF-α), among others. Th1 cytokines play a critical role in promoting cell-mediated immunity and activating macrophages to help fight intracellular pathogens.
T cells secrete what in Cell mediated immune response?
Cytokines
