Are marine mimivirus relatives probably large algal viruses?
Our results suggest that the numerous mimivirus-related sequences identified in marine environments are likely to originate from diverse large DNA viruses infecting phytoplankton. Micro-algae thus constitute a new category of potential hosts in which to look for new species of Mimiviridae.
CD(4)(+)CD(25)(+) regulatory T cells inhibit the anti-tumor activity of CIK cells. The interaction between CIK cells and DCs is sufficient for the blockage of the properties of regulatory T cells. CIK cells have the desirable properties for immunotherapy approaches, especially after co-culture with DCs.
