Researchers at the Center for Genomic Regulation (CRG) have described a system that achieved by reprogramming convert B cells into macrophages in 2 or 3 days. The work is magazine cover Cell Stem Cell and presents the results of the research group led by Austrian-alemanThomas Graf.
 Increasingly, research groups trying to uncover the mechanisms of cell differentiation to achieve reprogramming differentiated cells. This time, researchers have managed CRG describe a cellular reprogramming process that results in morphologically and functionally different cells with an efficiency of 100%.
Researchers have used stem cells and B cells have been reprogrammed to develop into macrophages by inducible expression of a single transcription factor. Both types of cells are part of the immune system but among them there are great differences in morphology, structural and functional.

Research conducted by a group of scientists from the Complutense University showed that certain characteristics of the immune system are the same in people centenarians and young adults. Good habits would not only live better and healthier but are also a requirement to live longer and healthier. This study provides new evidence to show that a good immune system is on life expectancy and biological age.
