(author), TNO Kwaliteit van Leven (author)The cellular composition of an atherosclerotic lesion is determined by cell infiltration, proliferation, and apoptosis. The tumor suppressor gene retinoblastoma (Rb) has been shown to regulate both cell proliferation and cell death in many cell types. To study the role of macrophage Rb in the development of atherosclerosis, we used apoE...article 2006

Mulder, S.J. (author), Mulder-Bos, G.C. (author), TNO Kwaliteit van Leven (author)Coeliac disease frequency increases by obscure reasons and affects in some Western countries as much as 1% of the populations. The second one of monozygotic twins does not develop the disease in 100% but only in 20-50%. To unravel these mysteries, literature was searched to determine the disease background and find suggestions for research and...article 2006
