What else can I help you with?
What secretes cytokines?
Yes. T cells can differentiate into several kinds of T cells such as Tregs, Th1, Th2, Th3, Th17 and others. Each specialized T cell can be be characterized (to some degree) by the cytokines they secrete. Th1 cells secrete IFN gamma while Th2 cells secrete IL4, IL5, IL9 and IL13. These are not the only cytokines they are capable of secreting, but these are the predominate ones.
What types of t cells are formed during activation?
T cells can be divided into CD4 cells (T helper cells) and CD8 cells (cytoxic T cells).There are then many different types of T helper cells, the main ones being TH1 and TH2 cells. TH1 cells are involved in antigen presentation and cellular immunity (eg. phagocytic cells). TH2 cells are involved in humoral immunity (production of antibodies) and allergy reactions.The cytokines (signalling molecules) released by the dendritic cell during T cell activation are responsible for the differentiation of T cells into different types. Further cytokines then cause the differentiation into TH1, TH2, etc.(There are also regulatory T cells which suppress the functions of other T cells to prevent the immune system attacking self molecules)
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.
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.
What are recombinant cytokines?
Recombinant cytokines, i.e., cytokines produced by expression from suitable cloning vectors containing the desired cytokine gene, can be expressed in yeast(see: Saccharomyces cerevisiae expression system), bacteria (see: Escherichia coli expression system), mammalian cells (see: BHK, CHO, COS, Namalwa), or insect cell systems (see: Baculovirus expression system).

What are Th1 and Th2?
Th1 and Th2 are part of your adaptive immunity. They are the effector T cells with specific function. Th1 acts directly on macrophages to make it able to defeat pathogens and Th1 activates B cells.

What are the regulators of immune response?
cytokines
Do T cells secrete cytokines as part of their immune response?
Yes, T cells secrete cytokines as part of their immune response.
What are the key differences between th1 and th2 T cells and how do they impact the immune response?
Th1 T cells are involved in cell-mediated immunity and help fight intracellular pathogens, while Th2 T cells are involved in humoral immunity and help fight extracellular pathogens. The key difference lies in the type of immune response they trigger. Th1 cells promote inflammation and activate macrophages, while Th2 cells stimulate B cells to produce antibodies. This balance between Th1 and Th2 responses is crucial for an effective immune response against different types of pathogens.
What are cytokines Explain their structure function?
cytokines are a number of small proteins that are secreated by a specific cell of immune system which carry signals and thus have an effect on other cells. cytokines are one type of protein that serve as messanger between cells it regulate various inflammatory responses Cytokines interact with cells of the immune system in order to regulate the body's response to disease and infection. Cytokines also mediate normal cellular processes in the body.How Cytokines WorkThe immune system is complex -- different types of immune cells and proteins do different jobs. Cytokines are among those proteins. Explaining how cytokines work is difficult. Cytokines are released by cells into the circulation or directly into tissue. The cytokines locate target immune cells and interact with receptors on the target immune cells by binding to them. The interaction triggers or stimulates specific responses by the target cells.
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 a category of signaling molecules that, like hormones and neurotransmitters, are used extensively in cellular communication. They are proteins, peptides or glycoproteins. The action of cytokines may be autocrine, paracrine, and endocrine. Cytokines are critical to the development and functioning of both the innate and adaptive immune response, although not limited to just the immune system. They are often secreted by immune cells that have encountered a pathogen, thereby activating and recruiting further immune cells to increase the system's response to the pathogen. Cytokines are also involved in several developmental processes during embryogenesis.
