In the May 22 Proceedings of the National Academy of Sciences, Bergsmedh et al. provide evidence that the uptake of apoptotic bodies can deliver oncogenes to the phagocytotic host cell (Proc Natl Acad Sci USA 2001, 98:6407-6411). They could detect the horizontal transfer of H-rasV12 or c-myc oncogenes from dying, transformed rat fibroblast cells to recipient mouse fibroblasts. DNA transfer was detected by PCR analysis and fluoresc

This gradually disappears during the healing stages through mechanisms that are not yet elucidated but which are essential to preserve vision. In the May British Journal of Ophtalomology, Noriko Ozaki and colleagues from the Nippon Medical School, Tokyo show that regression of the Arthus reaction in the cornea occurs via apoptosis.Ozaki et al injected bovine serum alb
