NIAID program aims to model immune responses and key infectious diseases

A new program at the National Institute of Allergy and Infectious Diseases (NIAID) aims to better understand the complex biochemical networks that regulate the interactions between infectious organisms and the human or animal cells they infect.

FoxM1 regulates the expression of oestrogen receptors in breast cancer

Research just published online in the "Journal of Biological Chemistry" identifies a new molecule involved in the regulation of oestrogen receptors (ER) expression in breast cancer.

Natural mechanism protecting tissue allografts from rejection

A molecule expressed during pregnancy seems to turn down the immune system, making it more tolerant of welcome visitors such as a fetus or maybe a transplanted heart, researchers say.

Proteolytic activity monitored by fluorescence resonance energy transfer through quantum-dot-peptide conjugates

Using a synthetic peptide modeled after the protein that the human immunodeficiency virus (HIV) uses to enter cells, a multi-institutional research team has created quantum dots that can penetrate the cell membrane and image internal structures in a cell.

Imaging pancreatic cancer with a peptide-nanoparticle conjugate targeted to normal pancreas

Most attempts to develop imaging agents that can better distinguish tumors from healthy tissue focus on finding molecules that are more abundant on malignant cells than on normal cells and using those as cellular targets.

Bone marrow adult stem cells repair a damaged heart

Researchers at the McEwen Centre for Regenerative Medicine at Toronto General Hospital have discovered the 'SOS' distress signal that mobilizes specific heart repair cells from the bone marrow to the injured heart after a heart attack.

Probable cause for Parkinson's found

Parkinson's, Alzheimer's, Lou Gehrig's disease and other brain disorders are among a growing list of maladies attributed to oxidative stress, the cell damage caused during metabolism when the oxygen in the body assumes ever more chemically reactive forms.

Researchers identify gene used to recognize pathogens

Researchers at the Johns Hopkins Bloomberg School of Public Health have identified a gene in the Anopheles gambiae mosquito's DNA that is central to the insect's ability to defend against infectious pathogens, including Plasmodium, the parasite that causes malaria in humans.

Scientists use embryonic stem cells to awaken latent motor nerve repair

In a dramatic display of stem cells' potential for healing, a team of Johns Hopkins scientists reports that they've engineered new, completed, fully-working motor neuron circuits - neurons stretching from spinal cord to target muscles - in paralyzed adult animals.
