Structure-building cell signals also may influence learning and memory

... had activated EphB receptors, and that there is a connection between synaptojanin-1 and bipolar disorders and schizophrenia. Until now, nobody had made the connection between EphB and the endocytosis involved in neurotransmitter regulation. "There's also an increase...

Some Brain Cells 'Change Channels' To Fine-tune The Message

... its neighbor are so close to one another at these connection points, called synapses, that molecules released from one cell travel immediately to the next. These molecules dock at specific places, or receptors, on the cell and trigger "channels" in the cell's membrane to open. Depending on the receptor and th...

Scientists identify genetic pathways essential to RNA interference

... to RNAi than RNA destruction," says Kim. "And the connection to DNA damage pathways, which was totally unexpected, suggests a potential connection between RNAi and the control of cell division in cancer." The researchers note that better understa...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

...use it's the first physiological data to confirm a connection between romantic love and motivation networks in the brain. "As it turns out, romantic love is probably best characterized as a motivation or goal-oriented state that leads to various specific emotions, such as euphoria or anxiety," Aron noted. "Wit...

Pulsating ultrasound enhances gene therapy for tumors

...for genes and we're making the case that there's a connection between the two." Other methods currently being investigated for enhancing gene delivery, such as lasers and electric current, are limited to surface lesions or require needles to be inserted in the body. Pulsed-HIFU is non-invasive and can treat an...

Sequencing of marine bacterium will help study of cell communication

...equence has allowed Stevens to begin exploring the connection between quorum sensing and other global regulatory networks through a combination of comparative genomics and experimental molecular biology. Other researchers are focusing on the relationship between the bacterium and its animal host. The PNAS arti...

X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

What is the connection between a fly’s aerodynamic skill and human heart function? Using the nation’s most brilliant X-rays, located at the Advanced Photon Source at the U.S. Department of Energy’s Argonne National Laboratory, a cardiac molecular motors expert from the Uni...

New SARS Protein Linked To Important Cell Doorway

...nce in SARS (Sudden Acute Respiratory Syndrome) in connection with Chinese New Year on February 9, researchers at Washington University in St. Louis have published insights into a new protein that could be an important contributor to the SARS virus' ability to cause disease and death. When the SARS virus first...

Research on Worms Yields Clues on Aging

...rnfeld."Our experiments show there is an important connection between neuralfunction and longevity," Kornfeld says. "We're continuing this line ofresearch to identify the precise functions of the nervous system thatcause the worms to live longer."Because the researchers found that anticonvulsants affect the ner...

Neuronal 'traffic jam' marks early Alzheimer's disease

...in. "This makes it clear there is some mechanistic connection between the transport deficit and plaque deposition. "So, our hypothesis is that in familial Alzheimer's disease -- or in disorders such as Down syndrome where beta-APP is overexpressed -- those defects cause early failure in cellular transport," he...

Genes In The Interferon System Important In Systemic Lupus Erythematosus

... we were able toidentify two genes with such clear connection to SLE," says ProfessorAnn-Christine Syvänen.A few years ago Lars Rönnblom and Professor Gunnar Alm at the SwedishUniversity of Agricultural Sciences were virtually the only researcherswho claimed that the interferon system, which is involved in the ...
