Discovery on immune system paves way to new vaccine against pneumococcal disease

A new breakthrough in the fight against pneumonia, meningitis and septicaemia has been announced today by scientists in Leicester and Dublin. The discovery will lead to a dramatic shift in our understanding of how the body's immune system responds to infection caused by Streptococcus pneumoniae and pave the way for more effective vaccines.

Lower-protein infant formula helps attain same growth rate as breastfed infants

Newly published findings indicate that infants fed a lower protein infant formula developed by Pfizer Nutrition gained weight at a similar rate to those who were breastfed, according to a study published online today in the European Journal of Clinical Nutrition. Pfizer Nutrition has always recognized that breast milk is the best source of infant nutrition. The study established that infants fed a new, lower-protein infant formula attained the same growth rate and growth pattern as breastfed infants.

Inviragen to present data on CHIKV vaccine at ASTMH meeting

Inviragen, a biotechnology company developing vaccines to protect against infectious diseases worldwide, together with investigators at the University of Texas Medical Branch (UTMB) and the Division of Vector Borne Diseases (DVBD) of the Centers for Disease Control and Prevention, will make an oral presentation today at the annual American Society of Tropical Medicine and Hygiene (ASTMH) meeting on preclinical results of the Company's experimental chikungunya virus (CHIKV) vaccine.

Virus fighting just got a new boost

In a ground breaking study in the UK researchers have identified a previously unknown mechanism that allows the immune system to fight viruses even after they have infected cells. Until now it was believed that antibodies can act only before the virus enters the cells. The team now has found that antibodies that attached themselves to a virus were able to follow it into cells and help to destroy the virus before it started to reproduce. This could open up new avenues of therapy.

Celldex third quarter net loss increases to $9.1 million

Celldex Therapeutics, Inc. today reported financial results for the third quarter ended September 30, 2010. Celldex reported a net loss of $9.1 million, or $0.28 per share, for the third quarter of 2010 compared to a net loss of $7.2 million, or $0.45 per share, for the third quarter of 2009. For the nine months ended September 30, 2010, Celldex reported a net loss of $25.2 million, or $0.79 per share, compared to a net loss of $23.6 million, or $1.49 per share, for the nine months ended September 30, 2009.

Soligenix completes enrollment in RiVax Phase 1B ricin toxin clinical trial

Soligenix, Inc., a late-stage biopharmaceutical company, reported today that it has completed enrollment of its Phase 1B clinical trial of RiVax™, a ricin subunit vaccine, in healthy volunteers. Preliminary results indicate that RiVax™ appears safe at all doses tested in volunteers. This trial is designed to assess the duration of immune responses using an adjuvant formulation of RiVax™ over a period of more than one year after vaccination.

Phytonutrient Report says Americans do not consume enough fruits and vegetables

The majority of Americans report getting a cold or flu in the past year, and more than a third say they'll make lifestyle changes to prevent getting sick again this year. However, 40 percent of Americans don't plan to take what is arguably the easiest and tastiest step to help potentially prevent illness this cold and flu season eat more fruits and vegetables daily.

Number of beta cells remains static after age 30: Research

Beta cells, which make insulin in the human body, do not replicate after the age of 30, indicating that clinicians may be closer to better treating diabetes.

Research on sheep population could help explain variation in vaccine protection

Strong immunity may play a key role in determining long life, but may do so at the expense of reduced fertility, a Princeton University study has concluded.

New findings suggest way to treat lung diseases

A new study of an exotic, infectious virus that has caused three recent outbreaks in the United States reveals clues to how the virus might damage lungs during infection. The findings also suggest possible new ways to treat lung diseases in humans.

New computational techniques to overcome obstacles in hard-to-study genes

Scientists have invented methods to scout the human genome's repetitive landscapes, where DNA sequences are highly identical and heavily duplicated. These advances, as reported today in Science, can identify subtle but important differences among people in the number and content of repeated DNA segments.

Vical to present preclinical results of HSV-2 vaccine program at Keystone Symposium

Vical Incorporated today announced that the company's Vice President of Clinical Development, Richard T. Kenney, M.D., is presenting preclinical results from the company's herpes simplex type 2 (HSV-2) vaccine program in a poster session Friday morning at the Keystone Symposium on Immunological Mechanisms of Vaccination (Seattle, October 27 – November 1).

Study: lncRNA are involved in host response to viral infection

Scientists have demonstrated for the first time that a certain class of RNA (known as long non-protein-coding RNA [lncRNA]) are involved in the host response to viral infection. These findings, published today in the online journal mBio-, could greatly change the way scientists look at the body's response to viral infection.

Bivalent oral polio vaccine produces better immune response than more commonly used trivalent vaccine, study says

The bivalent oral polio vaccine (bOPV) was found to induce a significantly higher immune response than the existing trivalent oral polio vaccine (tOPV), according to a study published on Tuesday in the journal Lancet, Reuters reports.

Jamieson releases flu-fighting formula with echinacea

Jamieson Laboratories, Canada's largest manufacturer of advanced natural-health products, announced the release of FluShield™, a clinically proven flu-fighting formula that is made with a patented, next-generation echinacea extract known as LPx3.

Long non-protein coding RNAs respond to SARS virus infection, says study

For the first time, scientists have discovered that a poorly understood class of RNA produced in a mammal's cells during a respiratory virus attack may affect the outcome of the infection. Their findings are reported today in mBio, a journal of the American Society for Microbiology.

Place of birth, low SES and exposure to pests associated with asthma in U.S.-born children

Researchers from Tufts University pooled data from five previous epidemiological studies to investigate the prevalence of asthma in children in the Boston neighborhoods of Chinatown and Dorchester. Among children born in the United States, low socioeconomic status (SES) and exposure to pests (mice and cockroaches) were both associated with having asthma. Neither association was present in children born outside of the United States. The study was published online in advance of print in the Journal of Immigrant and Minority Health.

Viral microRNA allows EBV to hide within cells and evade immune system

While most commonly associated with mononucleosis, Epstein-Barr virus (EBV) has been linked to many diseases that affect people long after the initial infection takes place, including some forms of cancer. In the current issue of the Journal of Biological Chemistry, scientists at The Wistar Institute describe how viral microRNA - small segments of RNA that suppress the effects of gene activity - allows EBV to hide within cells and evade the immune system.

Pathogenic listeria tricks intestinal cells to cause sickness

Pathogenic listeria tricks intestinal cells into helping it pass through those cells to make people ill, and, if that doesn't work, the bacteria simply goes around the cells, according to a Purdue University study.
