Very recently, it was found that IL-1β is expressed in nociceptive DRG neurons [7]. IL-1β expression is enhanced following crush injury to peripheral nerve and after trauma in microglia and astrocytes in the central nervous system (CNS) [8]. IL-1β can produce hyperalgesia following either intraperitoneal, intracerebroventricular or intraplantar injection [9, 10]. Moreover, IL-1β was found to increase the production of substance P and prostaglandin E2 (PGE2) in a number of neuronal and glial cells [11, 12]. IL-1ra, a specific IL-1 receptor antagonist, competitively binds to the same recepto

February 16, 2026 - Cytokines are the chemical messengers that help your immune cells fight germs. Learn more about how these tiny proteins keep you infection-free.

Figure 2. Structural variation in lipopolysaccharides (LPS) from different bacterial species results in differential immune system responses [2••]. Stimulation with Escherichia coli LPS (left) is a potent activator of the immune system and results in increased cytokine production of IL-10, TNFα, IL-1β and IL-6.

Secreted by Th1 cells, CD4+ cells, macrophages, and dendritic cells, these cytokines are characterized by production of several Interleukins (IL) - IL-1, IL-2, IL-12, IL-17, IL-18 as well as IFN-γ, and TNF-α.

4 days ago - Each cytokine has a matching cell-surface receptor. Subsequent cascades of intracellular signaling then alter cell functions. This may include the upregulation and/or downregulation of several genes and their transcription factors, resulting in the production of other cytokines, an increase ...

Cytokines are small proteins that help control the growth and activity of immune cells and blood cells.

The production of cytokines is triggered by specific stimuli that activate the relevant cells. These stimuli include antigens, microbial products, and inflammatory signals.

May 6, 2026 - When a cytokine binds to the outside of an immune cell, combinations of JAKs act as a “translator” sending an internal message that kicks off a chain of events, leading the cell to increase cytokine production, proliferate, become more adhesive, or produce other mediators in the immune response.

July 19, 2023 - Initial recognition of antigens is mediated by specific receptors located on monocytes, macrophages and dendritic cells and leads to the production of cytokines. Cytokines are low molecular-weight proteins that serve as chemical messengers to ...

November 19, 2019 - Whereas proinflammatory cytokines alert the immune system to the presence of potential infection or danger, dysregulated cytokine production can lead to immunopathology, including autoinflammatory and autoimmune disease, and, in some cases, can promote cancer.

June 1, 1995 - Cytokines participate in normal physiologic events within the CNS.At times of infection and inflammation, their role is emphasized by the upregulation of cytokines and their receptors within the CNS, with concomitant effects on brain function. Cytokines produced by glial cells, T cells, and macrophages interact within the CNS to determine the outcome of the inflammatory reaction.

Cytokines are a class of small proteins produced by the full range of inflammatory cells. They are active at low concentrations and may have paracrine, autocrine, or endocrine effects. Cytokines regulate the production of immune cells and other cytokines by either potentiating or attenuating ...

August 25, 2023 - Signaling Pathways: Cytokine production is initiated by binding of specific ligands to receptors on the cell surface. This binding triggers intracellular signaling cascades that activate transcription factors and induce gene expression.

July 24, 2026 - Cytokine, any of a group of small, short-lived proteins that are released by one cell to regulate the function of another cell, thereby serving as intercellular chemical messengers. Cytokines effect changes in cellular behaviour that are important in a number of physiological processes, including

Several recombinant cytokines are approved for therapeutic use; the manipulation of cytokines for therapy is reviewed by Tayal (Tayal and Kalra 2008). For example, recombinant IL-2, aldesleukin (Proleukin), is approved for the treatment of metastatic renal cell carcinoma and metastatic melanoma. IL-2 activates cells of the immune system including T cells, B cells, NK cells, and macrophages resulting in the enhanced production of other cytokines such as TNFα, IL-1, and IFNγ.

June 19, 2023 - Cytokines are essential mediators in the inflammatory process (Figure 1). Two cytokines, interleukin-1 (IL-1) and tumor necrosis factor (TNF), which have been recognized for decades, have been shown to coordinate the initiation and cascade of reactions [1]. They participate in the increase in vascular permeability and leukocyte production, stimulation and activation.

March 18, 2008 - Some of these regulatory proteins direct their associated mRNA molecules to discrete cytoplasmic foci (stress granules and processing bodies) that are essential in 'programming' mRNA 'metabolism'. Studies have begun to identify how these various mechanisms are integrated and regulated to determine the amount of cytokine production in cells involved in immune responses.

Moreover, stimuli that favour IL-4 production early after antigen exposure favour the development of Th2 cells.3 IL-13 is also associated with this subset of T cells.43 Like IL-4, and along with the fact that it maps closely to IL-4 and shares receptor α subunits with IL-4, IL-13 is expressed by activated T cells, induces IgE production by B cells and inhibits inflammatory cytokine production.44 These properties of IL-4 and IL-13 have been convincingly demonstrated in mice lacking the IL-4 or IL-13 gene.
