    ABSTRACT: CXCR2/IL-8RB was the only receptor previously reported in mice for ELR+ CXC chemokines, whereas the receptors for these chemokines in human include both CXCR1 and CXCR2. In this study, we cloned the full length cDNA of the mouse CXCR1 (mCXCR1) gene. The deduced amino acid of mCXCR1 was 77% and 58% identical to the rat and human CXCR1, respectively. RT-PCR and Northern blot analysis showed that mCXCR1 mRNA was expressed in lung, spleen, thymus, peripheral blood leukocytes, as well as in the isolated neutrophils. In a mouse respiratory inflammation model induced by lipopolysaccharide, a large number of neutrophils infiltrated into the lung and, meanwhile, the mCXCR1 expression was significantly increased in the recruited neutrophils, suggesting that mCXCR1 may mediate the recruitment of neutrophils to the inflammation site under certain infections.

    ABSTRACT: Thymus is the primary lymphoid organ involved in the development of thymocytes. Maturation related events of thymocytes within thymus, especially the widely discussed directional migration of thymocytes, is regulated by chemokines via chemokine receptors mediated signaling pathway. Multiple types of chemokines and chemokine receptors, as components of the network-interaction within thymic microenvironment, are involved in the thymopoiesis. It appears that these chemokines are functionally redundant and such phenomenon may be explained not only by the promiscuous, non-one-to-one matching between ligands-receptors within CXC or CC chemokine subfamily, but also by the various spatio-temporal expression patterns within different cell types and developmental stages. The redundancy and regulation of thymus expressed chemokines and chemokine receptors during thymocyte development are herein discussed.
