Study suggests loss of 2 types of neurons -- not just 1 -- triggers Parkinson's symptoms

08-13-2007 · EurekAlert!

New evidence indicates that the loss of two types of brain cells -- not just one as previously thought -- may trigger the onset of symptoms associated with Parkinson's disease. The evidence, based on mouse models, shows a link between the loss of both norepinephrine and dopamine neurons and the delayed onset of symptoms associated with Parkinson's disease. It was originally thought that the loss of only dopamine neurons triggered symptoms. Dopamine is a neurotransmitter critical for coordinating movement.

  1. Insight into dopamine role suggests new treatment pathway for Parkinson's
    10-18-2006 · EurekAlert!
    Dopamine (DA) not only functions as a neurotransmitter, a chemical messenger between neurons by which one neuron triggers another, researchers have found. It also appears to coordinate the activity of a particular neural circuitry. In studies with mice, they found evidence that the dopamine deficiency in Parkinson's and other related movement disorders may cause loss of muscle control and paralysis due to disruption of coordinated activity in this circuit.

  2. UCLA researchers discover link between Parkinson's and narcolepsy
    05-11-2007 · EurekAlert!
    UCLA researchers have found that Parkinson's disease patients have severe damage to the same small group of neurons whose loss causes narcolepsy. The findings suggest a different clinical course of treatment for people suffering with Parkinson's that may ameliorate their sleep symptoms.

  3. Some temper tantrum styles may be associated with clinical problems in preschool children
    12-19-2007 · EurekAlert!
    Temper tantrums are common among preschool children 3 to 6 years of age. Although these tantrums can range in duration and intensity, many parents often worry whether tantrums are also symptoms of more serious problems. A study published in the January issue of the Journal of Pediatrics suggests that certain types of tantrums may indicate serious emotional or behavioral disorders.

  4. Study suggests estrogen deficiency can lead to obesity-induced high blood pressure after menopause
    08-08-2007 · EurekAlert!
    At menopause, women lose hormone protection against heart and kidney diseases, and are likely to become obese. A research team has tested the idea that estrogen deficiency in aged females may trigger the development of high blood pressure and obesity. The results of their study, using an animal model, suggest that estrogen depletion can have these effects.

  5. People at genetic risk for Alzheimer's age mentally just like noncarriers
    01-07-2007 · EurekAlert!
    Australian researchers say that a genotype that heightens the risk for Alzheimer's disease does not contribute to cognitive change during most of adulthood. The largest study of its kind has found that carriers and noncarriers show the same type and extent of normal age-related cognitive declines, decades before carriers start to more often develop symptoms of dementia. The findings suggest that the higher-risk genotype acts only in later years to layer disease on top of normal aging.

  6. Study of the drug, Isradipine, to determine if it slows or prevents Parkinson's disease
    06-13-2007 · EurekAlert!
    Gloria E. Meredith, Ph.D., collaborated with D. James Surmeier, Ph.D. and others at Northwestern University to study the drug, Isradipine, and its effects on Parkinson's disease. Dr. Meredith studies a chronic mouse model that mimics the signs and symptoms of Parkinson's disease. The scientists joined together to see if the drug could stop cells from dying in the mouse model. Findings indicated that isradipine slowed the disease process and destruction of the dopamine-producing neurons.

    01-24-2008 · EurekAlert!
    Mesenchymal stem cells are capable of giving rise to various cell types through a process known as differentiation. A new study has determined that the anti-tumor drug bortezomib targets MSCs and leads to bone cell-specific differentiation. These data led the authors to suggest that Bzb might be a novel therapy for bone loss in individuals with osteoporosis and those with cancers accompanied by severe bone disease, such as myeloma.

    02-14-2007 · EurekAlert!
    While previous biomedical research studies have found that genetics and race increase risk for some diseases, a new look into how researchers study genetic triggers of type 2 diabetes suggests that defining race remains an inexact science, with social and historic facts mixing with biology throughout the research process.

    A new study compared a humpback whale brain with brains from several other cetacean species and found the presence of a certain type of neuron cell that is also found in humans. This suggests that certain cetaceans and hominids may have evolved side by side.

  10. Tracing Parkinson's lethal mechanism
    07-05-2007 · EurekAlert!
    In the vast majority of Parkinson's disease patients, the disorder arises not because of a genetic defect, but because some external insult triggers the death of dopamine-producing neurons. Now, researchers have reported progress in understanding the mechanism underlying that death, which they say suggests a new treatment pathway.
