Japan's Yoshinori Ohsumi wins Nobel Medicine Prize for work on cell 'recycling'
03 October 2016 Current Affairs GK: Yoshinori Ohsumi of Japan won the Nobel Medicine Prize  2016 on 3  Oct 2016,for his work on autophagy  a process whereby cells "eat themselves" which when disrupted can cause Parkinson's and diabetes.

Autophagy is a fundamental process in cell physiology with major implications for human health and disease.

The process is essential for the orderly degradation and recycling of damaged cell parts and its failure is believed to be responsible for ageing and cell damage.

Researchers first observed during the 1960s that the cell could destroy its own contents by wrapping them up in membranes and transporting them to a recycling compartment called the lysosome.Difficulties in studying the phenomenon meant that little was known until, in a series of brilliant experiments in the early 1990s, Yoshinori Ohsumi used baker's yeast to identify genes essential for autophagy.

The prize comes with eight million Swedish kronor (around $936,000 or 834,000 euros).

Last year, Irish-born William Campbell of the US, Satoshi Omura of Japan and China's Tu Youyou won the prestigious award for their discoveries of treatments against parasites.
