Immune cells from healthy individuals effectively kill cancer cells

Immune cells from healthy individuals can be the new immune cure for cancer. This treatment can kill cancer cells without destroying neighbouring cells. The hope is to eradicate cancer for ever.

Rituximab shows promise against primary biliary cirrhosis

An open-label study of rituximab, a monoclonal antibody for human CD20, was shown to be safe in patients with primary biliary cirrhosis (PBC) who had an incomplete response to the standard ursodeoxycholic acid (UDCA) therapy, also known as Ursodiol.

Multiple DNA repair defect in monocytes

Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood - so-called monocytes - are extremely sensitive to reactive oxygen species (ROS).

Version of 'Goldilocks' gene could determine future treatment for TB patients

'Goldilocks' gene could determine best treatment for TB patients Tuberculosis patients may receive treatments in the future according to what version they have of a single 'Goldilocks' gene, says an international research team from Oxford University, King's College London, Vietnam and the USA.

ACIP recommends changes in 2012 Recommended Adult Immunization Schedule

The CDC's Advisory Committee on Immunization Practices now recommends routine HPV vaccination for males aged 11 to 12 years and catch-up vaccination for males aged 13 to 21. These are just two of the changes to the 2012 Recommended Adult Immunization Schedule being published February 1 in Annals of Internal Medicine, the flagship journal of the American College of Physicians.

Natural resistance to flu could hold key to universal vaccine

Researchers have found that on infecting 41 healthy volunteers with different strains of flu virus, those with higher levels of a specific type of white blood cell were less likely to develop severe illness. Now the team of researchers hopes to mimic the natural resistance shown by some of the volunteers, by creating a vaccine that boosts levels of a particular subset of the 'T-cells'.

Peptides linked with internal flu viral structures can help develop universal vaccine

Researchers at the University of Southampton, University of Oxford and Retroscreeen Virology Ltd have discovered a series of peptides, found on the internal structures of influenza viruses that could lead to the development of a universal vaccine for influenza, one that gives people immunity against all strains of the disease, including seasonal, avian, and swine flu.

Anti-HER2 dendritic cell vaccine shows promise against DCIS

Researchers at the Perelman School of Medicine at the University of Pennsylvania report that a short course of vaccination with an anti-HER2 dendritic cell vaccine made partly from the patient's own cells triggers a complete tumor eradication in nearly 20 percent of women with ductal carcinoma in situ (DCIS), an early breast cancer.

Leprosy pathogen exploits micro-RNAs to weaken immune response

A team of UCLA scientists has found that the pathogen that causes leprosy has a remarkable ability to avoid the human immune system by inhibiting the antimicrobial responses important to our defenses.

IGC researcher awarded ERC Advanced Grant for tissue damage study

There is more to fighting infection than just clearing the body of pathogens. As important as resisting infection, is limiting damage to the host's tissue caused, very frequently, by toxins produced by pathogens or by components of the host immune response that clears those pathogens.

HPV transmission via oral sex practices suggests research

A new study suggested that an estimated 7% of American teens and adults carry the human papillomavirus in their mouths. This may help health experts finally understand why rates of mouth and throat cancer have been climbing for nearly 25 years. The evidence additionally makes it clear that oral sex practices play a key role in transmission.

Scientists develop new vaccine to treat cancer at pre-clinical level

Scientists in Trinity College Dublin, Ireland, have developed a new vaccine to treat cancer at the pre-clinical level. The research team led by Professor Kingston Mills, Professor of Experimental Immunology at Trinity College Dublin discovered a new approach for treating the disease based on manipulating the immune response to malignant tumours.

Duke team creates vaccine adjuvant of nanoparticles that target lymph nodes

Researchers at Duke University Medical Center have created synthetic nanoparticles that target lymph nodes and greatly boost vaccine responses, said lead author Ashley St. John, Ph.D., a researcher at Duke-NUS Graduate Medical School.

Study investigates immune response in cancer

In a study investigating immune response in cancer, researchers from Moffitt Cancer Center in Tampa, Fla., and the University of South Florida have found that interaction between the immune system's antigen-specific CD4 T cells and myeloid-derived suppressor cells (MDSC) - cells that play a major role in cancer-related immune suppression - dramatically change the nature of MDSC-mediated suppression. By contrast, the same effect was not observed when MDSCs interacted with the immune system's CD8 T cells.

New vaccine for deadly meningococcus B

A new study shows that a new 4-component meningococcal (4CMenB) vaccine for teenagers is effective when administered on a schedule of 2 doses from 1 to 6 months apart. María Elena Santolaya, from the Department of Pediatrics, University of Chile, Santiago, and colleagues performed the study, which was published online January 18 in the Lancet.

Alpha-hemolysin may play an unexpected role in UTIs

Researchers from the University of Utah have identified a process by which the most common types of urinary tract infection-causing bacteria are able to trigger bladder cell shedding and disable immune responses. According to this new study, published in the Jan. 19, 2012, issue of Cell Host & Microbe, α-hemolysin, a toxin secreted by many strains of Escherichia coli (E. coli), may play an important, unexpected role during both the establishment and persistence of urinary tract infections.

Researchers discover HS1.2 enhancer as the cause of SLE

A "genetic accelerator" is responsible for the most severe cases of Lupus (systemic lupus erythemathosus), an autoimmune disease: the accelerator, called enhancer HS1.2, speeds up the activity of some critical genes of the immune system involved in the disease.

Intestinal worm infections may not be bad

Intestinal worm infections may not be all bad, according to a new study by William C. Gause, PhD, and colleagues at UMDNJ- New Jersey Medical School. The researchers have found cytokines that help oust intestinal worm infections in mice also soothe associated lung injury and inflammation.

Human health depends on mosquito's immune response to pathogens

As mosquito-borne viral diseases like West Nile fever, dengue fever, and chikungunya fever spread rapidly around the globe, scientists at Virginia Tech are working to understand the mosquito's immune system and how the viral pathogens that cause these diseases are able to overcome it to be transmitted to human and animal hosts.

Bladder cancer is one of the top 10 most common forms of cancer in the US

Bladder cancer, most frequently caused by smoking and exposure to carcinogens in the workplace, is one of the top 10 most common forms of cancer in men and women in the U.S. More than 70 percent of bladder cancers are diagnosed in stage T1 or less and have not invaded the muscle layer.
