New Discovery On Role Of Vital Protein That Fights Meningitus
A University of Leicester researcher has discovered how a protein in the blood linked to defence against meningitis plays a more vital role than previously understood in the body's immune defence system.The published research has helped to advance medical understanding of how the body defends against disease and heals itself.
Fruit Fly Avoidance Mechanism Could Lead To New Ways To Control Pain In Humans
At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs.
Evidence Discovered For Suspected Cause Of Type 1 Diabetes
Scientists at Washington University School of Medicine in St. Louis working with diabetic mice have examined in unprecedented detail the immune cells long thought to be responsible for type 1 diabetes.Researchers were able to examine the immune cells from isolated insulin-making structures in the pancreas known as the islets of Langerhans.
International Study Discovers 10 New Genes Related To Human Growth
This meta-analysis, published in the latest issue of Nature Genetics, is based on data from more than 26,000 study participants. It verifies two already known genes, but also discovered ten new genes. Altogether they explain a difference in body size of about 3.5 centimeters.The analysis produced some biologically insightful findings. Several of the identified genes are targeted by the microRNA let-7, which affects the regulation of other genes.
Studying Regulation Of Genes To Understand The Underpinnings Of Most Human Diseases
A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature.
