Disabling a sensory organ prompts female mice to act like male mice

... key detector of pheromones, chemical signals that elicit specific behavioral responses in certain animals, including mice. The researchers found that female mice whose vomeronasal organs were genetically disabled behaved like males in the throes of courtship, exhibiting behaviors such as mounting, pelvic...

Einstein researchers' prototype vaccine could provide improved protection against tuberculosis

...accine have focused on boosting BCGmodifying it to elicit a stronger immune response in people, says Dr. Wil... the vital CD8+ memory T cells that a vaccine must elicit to optimally protect against infection. Since the completion of this study, the Einstein researche...

Handicapping tuberculosis may be the way to a better vaccine

...ed infection with the apoptosis-inducing strain to elicit a more dramatic immune response. The researchers observed that cytotoxic T lymphocytes (CTLs), which are needed for eliminating a pathogen and establishing a memory response, proliferated much more in the mice that had been infected with the apoptos...

Genomic analysis uncovers new targets for HIV vaccine

...tein, who said that a vaccine could be designed to elicit an HLA-C mediated response which HIV-1 might be unable to defuse. This study was the first time a genome-wide approach has been used for an infectious disease, Goldstein said. Past studies have looked at individual candidate genes. Since different ...

Cloning the male genome may help infertile men

...hen it is further developed and refined, it should elicit a favourable response from those involved in ethical issues, said Professor Takeuchi. But we are a long way from the time when this will be able to be used in humans. There is much work still to be done to understand why impaired development and ...

Blocking beta1-integrin to treat cancer

...ed to anything any more. However, thecells did not elicit metastasis and were unable to form tumours they stopped growing andbecame senescent. The authors suggest that the ablation of beta1-integrin function, and the resultinginduction of cellular senescence, represent a potential therapeutic goal for th...

Other potent S. aureus enterotoxins include the toxic shock syndrome toxin. These enterotoxins are classed as superantig...

Gene malfunctions cause schizophrenia, depression symptoms in mice

... two independent missense mutations in mouse Disc1 elicit distinct physiological, pharmacological, neuroanatomical, and behavioral phenotypes, which when taken together are strikingly consistent with the emerging picture from clinical and basic studies of DISC1 as a common genetic and biologically plausible...

All roads lead to GUN1

...nt signals had to be transmitted to the nucleus to elicit a protective reaction, it was unclear just how this information traveled. To start filling in the gaps, co-first author Ajit Nott, a former post-doctoral researcher in Chory's lab and now a researcher at Pioneer in Hyderabad, India, searched the Arab...

Ewwwww! UCLA anthropologist studies evolution's disgusting side

...orld, cultures have discovered that an easy way to elicit prejudice toward outsiders is to associate them with illness. Because emotional reactions that protect against disease are elevated during the first trimester, xenophobia comes along for the ride and is similarly increased early in pregnancy." Wome...

Targeting tumors the natural way

...esulting levels of alpha-Gal weren't sufficient to elicit the immune response, and the cells survived. The same wasn't true if the cell-binding agent delivered doxorubicin to cells instead: They were killed regardless of the amount of integrin they carried. Because target receptors on cancer cells usually r...

UCLA study uncovers clues for why Graves' disease attacks the eyes

...ic receptor like a key into a lock -- in order to elicit a cellular response. The receptors mobbed the patients immune systems, even on T-cells that normally would not produce them. "We didnt know why GD patients cells created a new antibody, but had a hunch that that it sprang from an immune abnormal...

...s," said Scassellati. "By building our machines to elicit this same type of behavior from humans, we hope to exploit the natural structure of social interactions to make robots more flexible, robust and intuitive to use." Scassellati will address both the technical challenges involved in the construction...

Creating new life forms that may help eradicate cancer affecting women

...ating the body's own killer (cytotoxic T) cells to elicit a stronger than normal immune response to the presence of cancer cells. The vaccines "teach" the immune system to mount a specialized, targeted response that is lethal to cancer. When Listeria is introduced in the body, it has a powerful, direct ...

MIT study shows genetic link for schizophrenia

These findings raised a novel and potentially important role for EGR genes in schizophrenia pathogenesis. In addition to Yoshik...

Human trial results show excellent safety data, from Geovax's DNA/MVA AIDS vaccines

... the vaccines, when administered at full dose, may elicit outstanding responses. More information will be released on the full dose trial when available later in 2007. GeoVax's AIDS vaccines contain only part of the HIV-1 virus and cannot cause AIDS. These vaccines contain the three major genes of the H...

Research to spotlight carbon monoxide benefits

... "You can use certain carbon monoxide molecules to elicit a whole range of biological effects. Carbon monoxide causes vasorelaxation and is produced naturally as a result of the breakdown of haemoglobin. This can be seen in the healing process of a bruise, where various colour changes indicate the degradati...
