Duffy Antigen

Background: Duffy antigen / receptor for chemokines (DARC) possesses high affinity for several chemokine subgroups of CC and CXC. Although DARC has been shown to play a role in many inflammatory diseases, its effect on chronic venous disease (CVD) remains unidentified. We explored whether the expression of DARC in skin tissue was activated under venous hypertension as well as the relationships between DARC and inflammation. Materials and methods: The inflammation in a rat model of venous hypertension caused by a femoral arterial-venous fistula (AVF) was studied. At specified intervals the pressure in the femoral veins was recorded within 42 days. Hindlimb skin specimens were harvested at different time points. The expressions of DARC, interleukin-8 (IL-8), and monocyte chemotactic protein-1 (MCP-1) in skin tissue were examined. Mononuclear cells infiltrated in skin tissue were detected. Results: Femoral venous pressures in AVF groups increased significantly at different time points (P < 0.01). DARC was expressed in skin tissue and its expression level increased significantly in AVF groups from the 7nd day on and was enhanced in a time-dependent manner within 42 days (P < 0.05). Meanwhile, both MCP-1 and IL-8 had higher levels, accompanied by increased mononuclear cells infiltrating into skin tissue (P < 0.05). Conclusions: A rat AVF model which can maintain venous hypertension for at least 42 days is competent for researching the pathogenesis of CVD. DARC, which plays a role in the inflammation of skin tissue under venous hypertension, may become a new molecular target for diagnosis and treatment of CVD at a very early stage.

AbstractIn spite of the introduction of several new drugs in the last 10 years, multiple myeloma (MM) remains incurable. Thus, an adoptive cellular therapy using chimeric antigen receptor T (CART), a strategy to increase the frequency of tumor-directed and functionally active T cells targeting antigens present on the cancer cell, might change the treatment in MM as it did in lymphoma and ALL. There are several targets for CART therapy in MM on different levels of development, which are discussed in the manuscript. B-cell maturation antigen (BCMA) being tested in the studies of phase 1–2 is the most promising, but so far CART has not been approved in the cure of MM and remains an experimental approach. The hematological society is facing a new technology which with its potential ability to cure MM, in spite of its complexity, cost, and toxicity, will definitely and soon change the landscape of myeloma in Europe and world-wide.
