Plants respond similarly to signals from friends, enemies

...ore does not need to attach itself to the plant to elicit a response. When the researchers studied L. japonicus plants missing the receptors that receive signals from other organisms ?certain genes in the plant were modified to accomplish this ?they discovered that the plants failed to respond to signals f...

Research advances quest for HIV-1 vaccine

...HIV-1 helps to define potential immunogens able to elicit 4E10-like antibodies. This is an excellent example of the tremendous potential for accelerating HIV vaccine design when scientists from multidisciplinary laboratories come together to tackle a major scientific challenge. " ### Rosa M.F. Cardoso, Mi...

Gene Vaccine Protects Mice Against Development Of Her2/neu Breast Cancer

...mice. “This is an exciting strategy that seems to elicit a completeimmunologic response against HER2/neu,?says the study’s lead author,Lawrence Lachman, Ph.D., a professor in the Department of ExperimentalTherapeutics. “Now that we have gone as far as we can in animalstudies, I hope this agent might be tes...

A comprehensive response to HIV could prevent 10 million AIDS deaths in Africa by 2020

Bird Brains Show How Trial and Error May Contribute to Learning

...trigger stimulations to LMAN at precise moments to elicit measurable effects on a predetermined syllable, song after song. The researchers found that different areas of LMAN tuned the same note in different directions, one area raising the pitch of a certain note and another area lowering its frequency. Th...

Influenza vaccine uses insect cells to speed development

...the surface of the virus, called hemagglutinin, to elicit an immune response against that specific strain of...where it has established safety and the ability to elicit a strong antibody response in humans. "Since all the media used here are chemically stable and comm...

Researchers find new genes necessary to make embryo

...enetrance" ?whereby the same genetic mutations may elicit different results in different individuals. "The results from the analyses of genes showing partial penetrance suggest the possibility of a general architectural motif in genetic networks," said Fabio Piano, an NYU biologist and lead author of the s...

Decoding the logic of olfaction

...lar among individuals. "This may explain why odors elicit similar responses in different individuals. For example, most people don't like the smell of skunk odor, but they do like the smell of chocolate," she said. The researchers also found that the spatial representations of the odors in the cortex expan...

UCLA scientists store materials in cells natural vaults

...urally occurring capsules may prove less likely to elicit an immune response than foreign carriers like viruses. IMPACT: The UCLA discovery will enable many potential applications, including: * Therapeutic delivery, such as homing cancer drugs directly to a tumor cell without harming healthy tissue ...

Ancient immune defense mechanism is no match for HIV-1

... was not known whether mammalian viruses naturally elicit this type of immunity in vertebrate cells. Drs. Yamina Bennasser and Kuan-Teh Jeang from the Molecular Virology Section at the National Institute of Allergy and Infectious Disease and colleagues found that infection with HIV-1 induces RNAi in human ...

Chemists synthesize molecule that helps body battle cancers, malaria

... the potency of antigens introduced in the body to elicit an immune response, allowing for lower vaccine dos...s is ensuring that the vaccine is potent enough to elicit a strong immune response," Gin said. "We will continue looking for ways to produce new molecules sim...

Active Vaccine Prevents Mice From Developing Prion Disease

...ons can easily infect the body because they do not elicit any immune response. To create a vaccine that could rally the immune system of mice, the NYU researchers designed a vaccine in which scrapie prions were attached to a genetically modified strain of Salmonella. This bacterium is also used in several ...

Specialized immune-system B cells play double-barreled role

...led antigens from the pneumococcus bacteria do not elicit a strong adaptive immune response in infants, people with compromised immune systems and the elderly. Such people may not have developed sufficient populations of B-1b cells to mount such an adaptive response. According to Tedder, such basic insight...

Study identifies gene in mice that may control risk-taking behavior in humans

..., researchers put them into a situation that would elicit a fear response in normal mice. They used a maze elevated 40 centimeters above a tabletop where mice had the option to walk along narrow, unprotected walkways or arms with protective walls. Half of the time the neuroD2-deficient mice chose the unprot...

Nose odors and mouth odors: The brain distinguishes

...o different chemicals butanol and farnesol did not elicit significantly different brain responses according to the route of delivery, indicating that the properties of the molecules do not play a role in the response. ...

Nanoscale method for investigating living systems

...ivity," says Blick. Because these artificial pores elicit bursts of current in the artificial membranes, the team believes quantum dots could perform similarly in other excitable cells such as neurons and muscles, and looks forward to understanding how the dots behave in vivo in excitable cells. The researc...

Scientists uncover new clues about brain function in human behavior

...cial and empathetic, even in situations that would elicit fear and anxiety in healthy people. They will eagerly, and often impulsively, engage in social interactions, even with strangers. However, they experience increased anxiety that is non-social, such as fear of spiders or heights (phobias) and worry ex...

Breast tumors in mice eradicated using cancer vaccine

...f the cell, it would target that pathway and would elicit a strong killer T cell response, and we have shown that," says Paterson. "Listeria is almost unique in the bacterial kingdom in doing this." In this model, pieces of the very large HER-2/Neu molecule are broken up into little fragments and bound to...

Male elephants woo females with precise chemistry

.... They also found that alterations in those ratios elicit different responses in not only female elephants, but also other male elephants near the male emitting the pheromone. "We were certainly quite surprised" by the results, said the study's lead author, David R. Greenwood, Ph.D., associate professor i...
