Researchers describe new human tissue dendritic cell with cross-presenting function

Researchers in Newcastle and Singapore have identified a new type of white blood cell which activates a killing immune response to an external source - providing a new potential target for vaccines for conditions such as cancer or Hepatitis B.

Skin microbiota may help protect the body from infection

A research team at the National Institutes of Health has found that bacteria that normally live in the skin may help protect the body from infection. As the largest organ of the body, the skin represents a major site of interaction with microbes in the environment.

Vitamin A insufficiency linked to hand, foot and mouth disease

Vitamin A status is associated with immunity to, and pathogenic condition of, hand, foot, and mouth disease in children, say researchers whose study results show that the majority of those with the infectious disease also had vitamin A insufficiency.

NIDA announces recipients of 2012 Avant-Garde Award for HIV/AIDS Research

The National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, today announced the recipients of the 2012 Avant-Garde Award for HIV/AIDS Research. The three scientists, Drs. David Smith, Samuel Friedman and Jeremy Luban, will each receive $500,000 per year for five years to support their research.

Study explores role of L. reuteri against foodborne infection

While many bacteria exist as aggressive pathogens, causing diseases ranging from tuberculosis and cholera, to plague, diphtheria and toxic shock syndrome, others play a less malevolent role and some are critical for human health.

Study describes 2010 whooping cough epidemic and details strategies to reduce infection incidence

Because whooping cough (pertussis) is almost as contagious as measles (affecting ~12-17 individuals with each case), clinicians are required to report cases of this bacterial respiratory tract infection to the state's department of public health. In 2010, California had the highest number of cases of whooping cough in 60 years. A new study scheduled for publication in The Journal of Pediatrics describes the 2010 whooping cough epidemic and details strategies to decrease the incidence of this infection.

Researchers discover potential drug targets that might reduce ventilator-induced lung inflammation

When hospital patients need assistance breathing and are placed on a mechanical ventilator for days at a time, their lungs react to the pressure generated by the ventilator with an out-of-control immune response that can lead to excessive inflammation, new research suggests.

Inhibiting STAT3 might unleash an effective anti-lymphoma immune response

Researchers at Moffitt Cancer Center and colleagues have demonstrated that the inhibition of signal transducer and activator of transcription 3 (STAT3) in mouse models of mantle cell lymphoma (MCL), an aggressive and incurable subtype of B-cell non-Hodgkin lymphoma that becomes resistant to treatment, can harness the immune system to eradicate residual malignant cells responsible for disease relapse.

Helper T cells may be frontline warriors when battling hepatitis A infection

Helper cells traditionally thought to only assist killer white blood cells may be the frontline warriors when battling hepatitis A infection. These are the findings from a Nationwide Children's Hospital study appearing in a recent issue of the Journal of Experimental Medicine.

New CD141hi DC subset plays a critical role in activating immune response against pathogens

Scientists at A*STAR's Singapore Immunology Network (SIgN), in collaboration with Newcastle University, UK, the Singapore Institute of Clinical Sciences and clinicians from multiple hospitals in Singapore, have identified a new subset of dendritic cells (DCs) in human peripheral tissue which have a critical role in activating our immune response against harmful pathogens.

Polio eradication: an interview with Dr. Kathleen O’Reilly

Polio is a disease caused by a virus and results in paralysis, usually in the legs, of those affected. The paralysis is irreversible. In some extreme cases the virus spreads to the nerve cells of the brain reducing breathing capacity and this rarer form can be fatal.

Novel treatment for cancer based on protein from HIV-1 virus

Yissum, Research and Development Company of the Hebrew University of Jerusalem, introduces a novel method for treating cancer based on Vif, a protein isolated from the Human Immunodeficiency Virus (HIV-1). The method was invented by Professor Emeritus Moshe Kotler and Dr. Roni Nowarski from the Department of Immunology and Cancer Research at the Hebrew University.
