The 2010 NF Conference – Connecting the Public with the Research

June 4, 2010 | by

Neurofibromatosis (NF) encompasses a set of genetic disorders that cause benign and malignant tumors to grow along various types of nerves; it can also affect the development of bones and skin. There are three main types of NF tumors: neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2) and schwannomatosis. NF1 is the most frequent of the three; one in every 3,000 children is born with the disease.

The Children’s Tumor Foundation (CTF) is the leading non-governmental funder of scientific research into neurofibromatosis and has funded NF studies for over 25 years. Their goal is to identify NF drug therapies and improve the lives of those living with the disorder. The Foundation also endeavors to increase public awareness of NF and provides resources for NF patients and their families.

Is Junk Food Addictive?

In a recent paper in Nature Neuroscience, two researchers at the Scripps Research Institute in Florida report that obese rats with extended access to what they deemed “palatable food” — bacon, sausage, cheesecake, pound cake, frosting and chocolate — exhibited compulsive like eating behavior, much like rats with extended access to cocaine or heroin [1]. This compulsive eating meant that they continued eating despite negative ramifications, in this case a flash of light signaling an oncoming electric shock administered to their foot. This lack of control over behavior with known negative consequences is a hallmark of both drug addiction and obesity. The investigators found that just like drug addicted rats, these obese rats had fewer striatal (a region of the forebrain) dopamine D2 receptors; this is responsible for the observed dampening of their neural reward responses to the food, which caused them to continue to eat, seeking that elusive high.
