Researchers discover human factor that drives maturation of helper T cells

A powerful arm of the immune system is production of antibodies that circulate through the blood and neutralize invading pathogens. Although B cells actually manufacture antibody proteins, the process is aided by neighboring T cells, which shower B cells with cytokines to make them churn out high-quality antibody proteins--and remember how to do so.

Key differences in immune response may explain young children’s proneness to infecion

Schools are commonly known as breeding grounds for viruses and bacteria, but this may not necessarily be linked to hygiene.

Immunotherapy in conjunction with drugs could be effective in treating pancreatic cancer

While immune therapy has proven effective in treating certain types of cancer, especially lung cancer and melanoma, tumors of the pancreas remain among the most difficult to treat and, so far, are impervious to immune-based therapies.

Study shows how genetic variants control immune cell response to pathogens

A study that is first in its kind and published in Nature Medicine today has looked at how far genetic factors control the immune cell response to pathogens in healthy individuals.

Studies shed more light on relation between bacteria, immune system and antibiotics

Antibiotics and the immune system are the two forces that cope with bacterial infections. Now, two studies from Isabel Gordo's laboratory, at Instituto Gulbenkian de Ciência, show for the first time that resistance to antibiotics and to the immune system is interconnected in bacteria.

New test strip can rapidly, cost-effectively detect disease pathogens

At present, bacteria, fungi or viruses can generally only be detected with certainty by way of elaborate laboratory tests or animal experiments. The food and pharmaceutical industries would like to have faster tests to check their products.

Enzyme from fermented Japanese vegetable boosts colon health in rats

An enzyme produced by fermenting a vegetable common in Japanese cuisine may be responsible for increasing the amount of at least one beneficial bacterium associated with healthy colons in a study using rats.

Fecal contamination in water can sicken swimmers

Recreational water illness is the overall term for sickness caused by bacteria or viruses in pools, lakes, rivers and other places people like to swim or play in hot weather.

Study could offer new ways to enhance cancer immunotherapy

When an immune T cell divides into two daughter cells, the activity of an enzyme called mTORC1, which controls protein production, splits unevenly between the progeny, producing two cells with different properties.

Merck partners with University of Nairobi to start medical oncology fellowship program for African doctors

Merck, a leading science and technology company, today announced to start the first Merck Africa Medical Oncology Fellowship Program for Sub-Saharan African countries in partnership with University of Nairobi, Kenya.

New strategy treats fatal autoimmune disease without outward off-target effects

In a study with potentially major implications for the future treatment of autoimmunity and related conditions, scientists from the Perelman School of Medicine at the University of Pennsylvania have found a way to remove the subset of antibody-making cells that cause an autoimmune disease, without harming the rest of the immune system.

Researchers design E. coli-based transport capsule to help fight pneumococcal disease

Most people recoil at the thought of ingesting E. coli. But what if the headline-grabbing bacteria could be used to fight disease?

Researchers develop computer model for speed analysis of TB's complex life-cycle

Tuberculosis (TB), caused by the pathogen Mycobacterium tuberculosis, is a serious global health problem accounting for 1.3 million worldwide deaths annually.

Scientists develop new vaccine to stimulate both innate and specific adaptive response

Though a variety of immunotherapy-based strategies are being used against cancer, they are often hindered by the inability of the immune response to enter the immunosuppressive tumor microenvironment and to effectively mount a response to cancer cells.

Implementation science may help prevent mother-to-child HIV transmissions

An emerging field, known as implementation science, may help reduce the nearly 150,000 instances of mother-to-child HIV transmissions that occur annually around the world, mostly in developing countries. c

AHR plays role in modulating the body's innate immune response to viral infections

A receptor, first known for its role in mediating the harmful effects of the environmental pollutant dioxin in our body, is now understood to play other important roles in modulating the innate immune response.

Paracetamol use during pregnancy linked to hyperactivity, autism spectrum symptoms in children

A new study has found that paracetamol (acetaminophen), which is used extensively during pregnancy, has a strong association with autism spectrum symptoms in boys and for both genders in relation to attention-related and hyperactivity symptoms.

Kataegis linked to better prognosis for breast cancer patients

Kataegis is a recently discovered phenomenon in which multiple mutations cluster in a few hotspots in a genome. The anomaly was previously found in some cancers, but it has been unclear what role kataegis plays in tumor development and patient outcomes.
