CX<sub>3</sub>CR1 expression was also lower, with a lower percentage of cells expressing CX<sub>3</sub>CR1 in the non-classical CD14<sup>+</sup>CD16<sup>++</sup> subset in all patients with asthma and this was inversely related to the percentage of cells expressing CCR2.
As in literature, azaindole is a very potent moiety, its derivatives displayed a number of biological activities such as kinase inhibitors, cytotoxic agents, anti-angiogenic activity, CRTh2 receptor antagonists, melanin agonists, nicotine agonists, effectiveness in alzheimer disease, cytokinin analogs, Orai inhibitors in asthma and chemokine receptor- 2 (CCR2) antagonists.
A CCL chemokine-derived peptide (CDIP-2) exerts anti-inflammatory activity via CCR1, CCR2 and CCR3 chemokine receptors: Implications as a potential therapeutic treatment of asthma.
No association was observed between the four polymorphisms and the presence of atopic rhinitis or atopic conjunctivitis and an elevated rate of serum IgE over 200 IU/ml.Additional effects of MCP-1 and its receptor CCR2 polymorphisms seem to be involved in disease susceptibility to asthma in Tunisian patients; nevertheless they could be protective against its severe forms.
We identified associations between the V-64I CCR2 polymorphism and protection against asthma, higher FEV1, and absence of BHR in families at high risk of asthma and atopy, suggesting an important role for the CCR2 receptor in modulating airway inflammation independent of atopy.
