Description: CCL24 (eotaxin-2) has been shown to induce chemotaxis of eosinophils, basophils and resting T lymphocytes but not monocytes and activated T lymphocytes. CCL24 is a strong suppressor of colony formation by a multipotential hematopoietic progenitor cell line. CCL24 interacts with chemokine receptor CCR3 to induce chemotaxis in eosinophils. Elevated levels of CCL24 has been seen in patients with aspirin-exacerbated respiratory disease (AERD), such as asthma.

Description: In recent years several groups have studied the sequence requirements, specificity, signalling pathways and kinetics of the TLR (Toll-like receptor) 9 suppression by inhibitory oligonucleotide motifs, which led to a class of novel inhibitory oligonucleotide (iODNs), that is independent of the previously thought species preference. Subsequently it has been discovered that telomeric DNA repeats (TTAGGG)n can block immune activation by CpG-ODNs. Short, 11-15 base long oligonucleotides were synthesized that were capable of potently inhibiting CpG-stimulation. The optimal inhibitory DNA motif consists of a pyrimidine-rich triplet, preferably CCT, which is positioned 5- to the GGG sequence in a singlestranded DNA molecule. Additionally, both the optimal spacing between the CCT and GGG motifs, as well as their relative order to each other, is of crucial importance for the inhibitory DNA action. Interestingly, although both TLR7/TLR8 ligands and bacterial DNA share the endosomal compartment for receptor binding and signal transduction, certain iODNs (G-type) suppress only TLR9-mediated activation, whereas prototype class I iODN may also interfere with the activation via the TLR7/TLR8 pathway. Recently, intriguing evidence has been presented that for some iODN classes the immuno-modulatory biological activity shows only limited sequence dependency or may not even involve TLR-mediated uptake and signaling pathways. For example iODNs of the class II are thought to act on immune activation through inhibition of STAT signaling and independent of TLR signaling via binding to a yet to be identified 'ODN-receptor'. Slightly modified phosphodiester versions of the most potent inhibitory ODNs were also able to profoundly block the immune activation of macrophages and just recently prove to be valuable tools for in vivo use in experimental animal models of inflammatory and auto-immune diseases. Based upon these recent insights the following classification for iODNs has been suggested: Class I: G-stretch ODNs: TLR9-specific competitors, some iODNs may also affect TLR7 and TLR8 signalingClass II: ODNs with telomeric repeats: TLR-independent inhibitors of STAT signalling (cellular uptake via an 'ODN receptor'?)Class III: Inhibitors of DNA uptake in a sequence independent mannerClass IV: Long phosphorothioate ODNs as direct competitors of TLR9 signaling in a sequence independent manner

Description: The reagent, a cyanine dye, can be used as a label for the determination of proteins with NIR-fluorescent technology. The absorption-maxima of the reagent lies in a region of low interference by other biomolecules. The isothiocyanate-moiety is used to link the reagent to proteins which can sensitively be detected. Experiments to lower the detection-limits of immunoassays have been done.

Description: N-Dodecanoyl-L-homoserine lactone (C12-HSL) is a small diffusible signalling molecule involved in quorum sensing, thereby controlling gene expression and affecting cellular metabolism in bacteria. In addition to regulating bacterial functions, C12-HSL activates NF-kappaB in RAW 264.7 macrophages, increasing the expression of TNF-alpha, interleukin-1beta (IL-1beta) and IL-8, while other lactones do not. In addition, C12-HSL alters cell cycling and metabolism of human keratinocyte (HaCaT) cells. It is important to note that C12-HSL is distinct from N-3-oxo-dodecanoyl-L-homoserine lactone, which is produced at different times in biofilm development and has different cellular effects.
