3-Bromotyrosine, a product of protein oxidation, is generated after eosinophil activation during allergic responses. It serves as a biomarker for eosinophil peroxidase-induced protein oxidation both in vitro and in vivo. Beyond its association with eosinophils, 3-bromotyrosine levels are significantly elevated in peritoneal exudate from K. pneumoniae-infected mice, indicating a fivefold increase compared to uninfected controls, which implies that neutrophils may release increased levels of oxidized products during inflammation. Furthermore, in humans, allergen-challenged lung samples from patients with allergen-induced asthma show a tenfold increase in 3-bromotyrosine, highlighting its potential as a marker for oxidative stress in allergic conditions.

<p>The lipopeptide FSL-1, synthesized on the basis of the N-terminal structure of a M. salivarium lipoprotein, is capable of inducing the cell surface expression of ICAM-1 in human gingival fibroblasts. It furthermore revealed an activity to induce production of monocyte chemoattractant protein 1, interleukin-6 (IL-6), and IL-8. FSL-1 also activated macrophages to produce tumor necrosis factor alpha. Overall, results by Okusawa and coworkers suggest that the diacylglyceryl and the peptide portions of FSL-1 are indispensable for the expression of biological activities and for the recognition by Toll-like receptors 2 and 6. Furthermore, the same authors conclude that the recognition of FSL-1 by Toll-like receptors 2 and 6 apparently is hydrophobic.</p>
