Weston-based biotech company Biogen Idec has donated $500,000 to a University of Massachusetts Medical School fund that finances research of Lou Gehrig's disease, also known as ALS.
The fund was created with the help of former Gov. Paul Cellucci, who announced early last year that he had been diagnosed with ALS. He is receiving treatment at UMass, where Dr. Robert H. Brown leads the institution's research efforts on ALS and other neuromuscular diseases.
The fund has raised $1.3 million to date. Biogen's donation, the largest yet, comes in advance of a Boston fundraiser chaired by all living former Massachusetts governors, as well as Gov. Deval Patrick and Lt. Gov. Tim Murray.
