To understand the pathomechanism of RA, we attempted to characterize the rheumatoid synovial cell and found

To our knowledge, it has by no means been completely investigated to which extent immune defects in obob or dbdb animals are linked to leptin deficiency or, respectively, leptin receptor deficiency per se, as opposed to confounding components which include hypercorticosteronemia. To examine the importance of direct effects of leptin PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/23118721?dopt=Abstract on lymphopoiesis and immune response, we generated bone marrow chimeras by transplantation of dbdb bone marrow cells into lethally irradiated normal recipient mice, which give a standard environment for the grafted cells. Donor dbdb mice show a marked atrophy of the thymus as compared with db+ controls. In bone marrow chimeras, the size and cellularity of your thymus weren’t various among mice grafted with dbdb or db+ bone marrow weeks right after the graft, suggesting that the thymic atrophy observed in dbdb ISA-2011B site donors just isn’t on account of direct effects of leptin on lymphocytes. Furthermore, RT-PCR analyses suggest that CDCD double good thymocytes usually do not express ObRb. Further studies are in progress as a way to examine which cell varieties respond to leptin within the thymus and regardless of whether impaired leptin signaling in lymphocytes impacts immune responses after antigen challenge in dbdb bone marrow chimeras.
