The use of immunoglobulin (Ig) preparations (intravenous, IVIg, subcutaneous, SCIg) for replacement and immunomodulation therapy worldwide has tripled in the past 20 years and represents an ever‐increasing cost factor for healthcare organizations. The limited access to the starting material of this essential medicinal product is currently the driving force for human plasma collection. Increasing awareness and improved diagnosis of human primary immunodeficiencies and a broadening of immunomodulatory indications are responsible for this development, and on a longer run might lead to plasma supply shortages. Consensus recommendations for the optimal use of Ig in clinical practice, including priority rankings for the most urgent indications, are therefore urgently needed. During a recent meeting in Kreuth, Germany, expert nominees from 36 Council of Europe states, together with colleagues from observer countries and regulatory agencies came up with this consensus statement.
Objective:To observe the effect of co-culture cytokine-induced killer cells(CIK) and homologous dendritic cells(DC) on the proliferative activity and phenotype change of the DCCIK cell and the cell killing activity of leukemia HL-60.Methods:50 mL cord blood sample was obtained from infants delivered by full term healthy woman and the cord blood mononuclear cells were isolated by density gradient centrifugal ion.Non-adherent cells were collectedfor the induction culture of CIK.adherent cells were differentiated into mature DC;cultured mature DC was mixed with and CIK in the proportion of 1:5 for 12 d.killing activity of DC-CIK co-cultured cell on leukemia HL-60 was detected by MTT assay.Results:Compared with CIKs.the cocultured DC-CIKs presented a markedly higher proliferation and killing activity.Conclusions:Co-culture of DC-CIK cells led to a significant increase of the proliferation and cytotoxicity of CIK. 相似文献
