, Columbia, MD, USA) failed to meet its primary clinical endpoint of achieving a significant increase of complete response of steroid-resistant graft-versus-host disease lasting at least 28 days compared with placebo. Although peer-reviewed publication of the trial and its results are not in public domain at the time of this writing, it is worthwhile to reflect on the apparent discrepancy between the European experience CH5424802 and this industry-sponsored phase III study. This review presents a heuristic failure analysis focusing on the potential variables affecting MSCs and their utility as a cellular pharmaceutical.”
“Gamma delta

(?d) ? cells are non-conventional T lymphocyte effectors that can interact with and eradicate tumour cells. Several data demonstrate that these T cells, which are implicated in the first line of defence against pathogens, have anti-tumour activity against many find more cancers and suggest that ?d ? cell-mediated immunotherapy is feasible and might induce objective tumour responses. Due to the importance of ?d ? lymphocytes in the induction and control of immunity, a complete understanding of their biology is crucial for the development of a potent cancer immunotherapy. This review discusses recent advances in ?d ? basic research and data from clinical trials on the use of ?d ? cells in the treatment of different cancers. It analyses how this

knowledge might be applied to develop new strategies for the clinical manipulation and the potentiation of ?d ? lymphocyte activity in cancer immunotherapy.”
“Selected lymphocyte subpopulations were studied and the distribution of viral mRNA were investigated during acute and persistent porcine rubulavirus (PoRV-LPMV) infection in Vietnamese

pot-bellied pigs. Six pigs infected with PoRV-LPMV at 17 days of age exhibited clinical signs 7-10 days post-inoculation (pi). One infected piglet died 11 days pi while selleck inhibitor the other five recovered around day 13 pi and survived until euthanasia on day 277 pi. Increased numbers of CD8+, CD4+ and CD2+ T cells were detected during the acute phase of infection while CD8+ cells were elevated throughout the infection, including during the persistent stage. Specific antibodies against the haemagglutinin-neuraminidase protein of PoRV-LPMV were detected during persistent infection. Although infectious virus could not be recovered from tissues from any of the infected pigs at necropsy 277 days pi, PoRV-LPMV mRNA was detected in lymph nodes, pancreas and central nervous system using a nested polymerase chain reaction technique. Continued lymphocyte interaction with viral RNA may be an important factor in promoting cellular and humoral responses during persistent PoRV-LPMV infection. (C) 2008 Elsevier B.V.
