Researchers create 'suped up' gene that forces cancer cells to self destruct

Researchers at the University of Rochester have designed a gene that produces a thousand times more protein in cancer cells than in healthy cells.

Promiscuity fears pose barrier to cervical cancer vaccinations

The public's concerns about costs and increased promiscuity among teenagers appear to be hindering use of a vaccine against the human papilloma virus (HPV) to prevent life-threatening diseases, according to a study by researchers at Yale School of Public Health.

Circumcision reduces risk of HIV infection in heterosexual men

A new U.S. study has found that being circumcised significantly reduced the risk of HIV infection in heterosexual African American men known to have been exposed to the virus.

New anti-tumor gene called SARI

Researchers from Virginia Commonwealth University have identified a new anti-tumor gene called SARI that can interact with and suppress a key protein that is overexpressed in 90 percent of human cancers.

Discovery of new way a man can transmit the HIV virus to a woman

Scientists had long believed that the normal lining of the female vaginal tract was an effective barrier to invasion of the HIV virus during sexual intercourse. They thought the large HIV virus couldn't penetrate the tissue.

Researcher refines aptamers to prevent HIV resistance

Evolving HIV viral strains and the adverse side effects associated with long-term exposure to current treatments propel scientists to continue exploring alternative HIV treatments.

Just a little squeeze lets proteins assess DNA

To find its target, all a protein needs to do is give quick squeezes as it moves along the DNA strand, suggests new research from The University of Arizona in Tucson.

Mucosal lining of the female genital tract no barrier to HIV sexual transmission

Contrary to a widely-held assumption about heterosexual transmission of HIV, the normal mucosal lining of the female genital tract is not a foolproof barrier to viral penetration, scientists at the Northwestern University School of Medicine in Chicago report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Study of placenta unexpectedly leads to cancer gene

University of Rochester Medical Center scientists discovered a gene mutation that impairs the placenta and also is influential in cancer development, according to a study published online December 16, 2008, in the journal PLoS (Public Library of Science) Biology.

Researchers simplify creation induced pluripotent stem (iPS) cells

Bryce Carey, an MIT graduate student working in the lab of Whitehead Member Rudolf Jaenisch, spearheaded the effort by joining in tandem the four reprogramming genes through the use of bits of DNA that code for polymers known as 2A peptides. Working with others in the lab, he then manufactured a so-called polycistronic virus capable of expressing all four reprogramming genes once it is inserted into the genomes of mature mouse and human cells.

Researchers solve failed vaccine mystery

Research led by Johns Hopkins Children's Center scientists has figured out why a respiratory syncytial virus vaccine used in 1966 to inoculate children against the infection instead caused severe respiratory disease and effectively stopped efforts to make a better one.

Roche's new dual-target HIV-1 test approved in Europe

Roche announced today that its innovative dual-target HIV-1 test has received CE Mark certification, allowing it to be sold for clinical use in the European Union. The COBAS AmpliPrep/COBAS TaqMan HIV-1 Test, v2.0 utilizes a unique design to simultaneously amplify and detect two separate regions of the HIV-1 genome.

NACCHO to donate up to one million doses of FluMist

The National Association of County and City Health Officials (NACCHO) has announced a donation of up to one million doses of FluMist (Influenza Virus Vaccine Live, Intranasal) by MedImmune in a partnership aimed at increasing influenza awareness and vaccinations in underserved communities and populations.

Researchers develop universal influenza vaccine for animals

A University of Maryland-led science team has developed a universal influenza vaccine for animals that may help prevent or delay another human flu pandemic.

Overactive brain enzyme may play role in preventing weight gain and obesity

Researchers at Albert Einstein College of Medicine of Yeshiva University have found that overactivity of a brain enzyme may play a role in preventing weight gain and obesity.

Novavax announces positive results in trial of seasonal influenza VLP (trivalent) vaccine candidate

Novavax, Inc. has announced favorable results from a Phase IIa human clinical trial of its seasonal influenza VLP (trivalent) vaccine candidate.

Gene therapy used to treat periodontal disease

Scientists at the University of Michigan have shown that gene therapy can be used to successfully stop the development of periodontal disease, the leading cause of tooth loss in adults.

Scientists show that HIV's evolution in the body does not occur at a constant rate

HIV is so deadly largely because it evolves so rapidly. With a single virus as the origin of an infection, most patients will quickly come to harbor thousands of different versions of HIV, all a little bit different and all competing with one another to most efficiently infect that person's cells. Its rapid and unique evolution in every patient is what allows HIV to evade the body's defenses and gives the virus great skill at developing resistance to a pantheon of antiviral drugs.

Vaxfectin-formulated H5N1 pandemic influenza achieves T-cell responses and cross-clade reactivity in humans

Vical Incorporated has announced that the company's Vaxfectin-formulated H5N1 pandemic influenza DNA vaccines induced T-cell responses against a matching strain of influenza virus and demonstrated cross-clade antibody responses against a different strain in a Phase 1 clinical trial.

Mathematical models of adaptive immunity

More than five million people die every year from infectious diseases, despite the availability of numerous antibiotics and vaccines. The discovery of penicillin to treat bacterial infections, along with the development of vaccines for previously incurable virus diseases such as polio and smallpox, achieved great reductions in mortality during the mid-20th century.
