Among several mediators released by neutrophil granulocytes, neutrophil gelatinase-associated protein (NGAL) in urine has attracted interest as a biomarker of inflammation and acute kidney injury (AKI) [4].
Altogether, these mediators released by keratinocytes cause erythema, pain, and a UV-induced skin response and thickening (Lee et al., 2009; Jain et al., 2011; Lee et al., 2011).
This situation is further complicated by the vasoactive and pro-inflammatory mediators released by damaged and necrotic alveolar macrophages, followed by increased accumulation of fluids in the septal interstitium (Fig. 1).
These findings raise the possibility that mediators released by cells could be isolated and delivered systemically or locally to treat lung injury, obviating the need to administer the MSCs themselves.
The immune response during sepsis is complex and involves a network of control elements that includes pathogen-associated molecular patterns, cell adhesion molecules, pro- and anti-inflammatory mediators released by activated macrophages, and complement activation.
General muscle wasting that often occurs in COPD may be partly due to inflammatory mediators released by the lungs into the blood.
Soluble mediators released by injured cells activate polymorphonuclear neutrophils and other types of cells that accumulate at the site of injury [1].
Cell-cell contact by Pam2Cys peptide-stimulated BMDC and NK cells rather than soluble mediators released by stimulated BMDC induced activation of NK cells.
Among the inflammatory mediators released by mast cells, many are preformed and stored in secretory granules, and can be discharged upon exposure to a number of different stimuli such as crosslinking of IgE bound to the high affinity IgE receptor (FcεRI) [8].
Instead, monocyte-derived macrophages (MDMs) and parenchymal microglia are the productively infected cells within the brain [2], [3], and it is the viral proteins and inflammatory mediators released by these cells that damage neurons either directly or by causing glial dysfunction (reviewed in [2], [4].
Inflammatory mediators released by the adipose tissue can lead to local insulin resistance and endothelial dysfunction.
