Chemical in sperm offers new weapon to fight ageing.Byline: ANI London, October 7 (ANI): Graz University scientists in Austria say that compound found in human sperm, known as spermidine sper·mi·dine n. A polyamine compound found in ribosomes and living tissues and having various metabolic functions. It was originally isolated from semen. , may prove the next weapon in the fight against ageing. They have found that spermidine slows ageing processes, and increases longevity in yeast, flies, worms, mice, and human blood cells blood cells, n.pl the formed elements of the blood, including red cells (erythrocytes), white cells (leukocytes), and platelets (thrombocytes). blood cells See erythrocyte and leukocyte. Platelets are classed separately. by protecting cells from damage. The researchers point out that cell ageing happens when a process whereby damaged cells or parts of cells are recycled, scientifically known as autophagy autophagy /au·toph·a·gy/ (aw-tof´ah-je) 1. lysosomal digestion of a cell's own cytoplasmic material. 2. autophagia. autophagy 1. lysosomal digestion of a cell's own cytoplasmic material. 2. , goes wrong. They further state that spermidine concentration has also been found to decline with age. They have found that adding spermidine suppressed various processes associated with ageing, and reduces free radicals and increasing lifespan. In a study on fruit flies, the researchers observed that treated insects lived 30 per cent longer than their untreated counterparts. Worms who were treated using the new approach were found to live 15 per cent longer than those untreated. Tobias Eisenberg, a researcher, says that this is the "holy grail Holy Grail: see Grail, Holy. A very desired object or outcome that borders on a sacred quest. There are several Holy Grails in the computer business. of age research". Meanwhile, a British newspaper has suggested that a "wonder pill that could extend lifespan by up to 25 years" may soon be available. However, the truth is that human trials, let alone treatment, are a very long way off, reports the Telegraph. In an article, the patient information website NHS NHS abbr. National Health Service NHS (in Britain) National Health Service Choices agrees that this is an exciting area for future research, but adds that it will take many more years of study including lab tests and further animal trials before it can be safely tested on humans. The article also points out that this is at least the second elixir elixir /elix·ir/ (e-lik´ser) a clear, sweetened, alcohol-containing, usually hydroalcoholic liquid containing flavoring substances and sometimes active medicinal ingredients. e·lix·ir n. of eternal youth that has been 'discovered' in the last few months.
