In 2009, Nobel in Medicine and Physiology was awarded to three scientists for their research on telomeres and telomerase. All normal human somatic cells have a finite number of times. Cells are described as cellular senescent when the limit is reached during their division. Telomere shortening has been associated with cellular aging, which leads to body aging because of the lack of cellular functions. In activated T cells unlike most somatic cells, telomerase activity is upregulated, resulting in increased telomere length. However, this brief period of telomerase induction only delays cellular senescence. Naturally, there is a great deal of interest in finding inducers of telomerase that may help delay the onset of cellular aging.
