UCLA study finds clues to diabetes puzzle

...ns today's soaring diabetes rates will continue to mount as people whose ancestors were never exposed to the epidemic adopt the disease's twin risk factors: abundant food and more sedentary lifestyles. Already, the disease affects 150 million worldwide. "At its present rate of increase, within a few decade...

Novel flu vaccine shows promise in mice

...ection of the fact that the immune system does not mount a vigorous response to it, so that evolutionary pressure on that region of the virus is not great. "Among human influenza virus strains, there is little variation in the M2 region," Gerhard says. "That could be due to the fact that humans do not gene...

Bacterial viruses make cheap easy vaccines

...t of the number of pieces of naked DNA required to mount an effective immune response. Using bacteriophages to deliver vaccine components offers several advantages over vaccination with naked DNA, says March. The DNA is protected inside the protein shell of the virus making it longer lasting and easier to...

Receptor could be target for cancer therapy

...stem function -- the EP2 knockout mice appeared to mount an effective tumor-killing immune response; the control mice did not. Breyer's focus on the EP2 receptor stems from his long-standing interest in the biological effects of prostaglandins, a family of locally acting hormones produced by the cyclooxyge...

Could one less cookie a day help the fight against fat?

...ording to Hill. The long-term approach would be to mount a social change campaign, akin to those for smoking cessation, seat belt use, and recycling, to build an environment more supportive of healthy lifestyles. The short-term goal of stopping weight gain requires first pinpointing what Hill calls the en...

Newly identified gut protein kills bacteria

...ntestinal lining, where they could cause damage or mount an invasion. Moreover, the researchers were surprised to find production of Ang4 is controlled by a bacterium that makes its home in the intestine. The microbe, called Bacteroides thetaiotaomicron, is a prominent member of the mouse and human gut mi...

New drug lead fights bacteria that can be lethal by disrupting quorum sensing and biofilms

...rtain level, Suga explained, so that they then can mount an effective attack. The process gets switched on, he said, in response to the autoinducers that accumulate in bacterial cells as they begin reproducing. Once the cells "sense" that a quorum has been reached, they begin to communicate, a process t...

In healthy children under 12 years of age, vaccination in a single dose is recommended, while two doses are recommended for adolescents. Without vaccination, infections in children whose immune systems ...

Using the ocean's living light shows to fight terrorism or track the planet's most massive migration

...idder is now miniaturizing the SPLAT-Cam system to mount it on a single frame with the HIDEX-BP. This will allow easy deployment around the world, whereas submersible work is limited by cost and logistics. The Widder group is also working toward creating additional devices that could be used as part of a...

Code-breaking insects steal plants' defensive signals, enabling counterattack

...The researchers found that the earworms ability to mount its own defenses begins with exposure to very low levels of jasmonate and salicylate. The exposure of earlier stage caterpillars to the molecules also triggers a response before they begin feasting. Exposure at the penultimate larval stage to these...

Rockefeller researchers provide the first functional evidence for mammalian pheromone receptors

...ir normal counterparts, the mutant males tended to mount females fewer times, and the more they were exposed to females, the less they mounted. Normally, male and female mice that spend time together engage sexual behavior with each other. This gain of sexual activity through experience does not occur in m...

Pinpointing the mutations that cause resistance to Gleevec

...this initial study, we believed it was critical to mount a much more comprehensive search for mutations in BCR-ABL ." In their current study, Sawyers and his colleagues searched for mutations in 32 patients in differing stages of CML. Each of the patients had developed resistance to Gleevec. Kuriyan and h...

Making the most of lymphopenia

Once the immune system is activated, it will go about killing these cancer cells in a discriminate fashion. Now, the study by Theofilopoulos and his colleagues suggests the ...

Stanford study finds potential shingles prevention in a childhood vaccine

As bodies age, disease-fighting cells lose punch

As occurs in many parts of the aging mind and body, the immune system becomes less responsive to new challenges, s...

Study yields new clues on bodys rejection of transplanted organs

...that T cells rely on the spleen and lymph nodes to mount an immune response against toxins, bacteria and the foreign blood cells of a transplant. In the new study, investigators discovered that memory T cells, unlike nave (resting) T cells, can trigger the rejection of a transplant even when the spleen an...
