Ebola then and now: Eight lessons from West Africa that were applied in the Democratic Republic of the Congo

Posted by in categories: biotech/medical, health

The devastating 2014–2016 Ebola epidemic in West Africa prompted changes in the way the world responds to outbreaks and other health emergencies. Here are eight things that are being done differently in the response to the Ebola outbreak in the Democratic Republic of the Congo (DRC).

Horizontal gene transfer from mother to infant influences gut microbiome assembly, neurodevelopment, and immune maturation in infants

Posted by in categories: biotech/medical, health, neuroscience

In a recent study published in Cell, researchers used a multi-omics approach to profile the gut microbiomes and metabolomes of mothers and infants to determine the vertical and horizontal transmission of bacterial species and strains as well as individual genes and understand the dynamics of the gut microbiome assembly that shape the development of the infant before and after birth.

The vertical transmission of gut bacteria from mother to fetus during pregnancy and the horizontal transfer of microbes through breast milk plays a vital role in the physical and cognitive development of the infant long after birth. Studies have shown associations between the gut microbiota composition of breastmilk and the development of the infant’s immune system, as well as autoimmune conditions and allergies. Furthermore, allergies and autoimmune disorders have also been linked to exogenous proteins in infant formula.

Metabolites produced by gut microbiota are also associated with the infant’s cognitive development. However, the development of gut microbiomes and metabolomes in the perinatal stage and their role in infant development remains unclear.

Graphene oxide elicits microbiome-dependent type 2 immune responses via the aryl hydrocarbon receptor Nanotechnology

Posted by in categories: biotech/medical, health, nanotechnology

Although the toxicity of graphene‐based nanomaterials on human health has been extensively studied, their impact on the microbiome remains poorly understood. Using zebrafish as a model, we show that graphene oxide modulates the immune system in a microbiome‐dependent manner through a mechanism mediated by the aryl hydrocarbon receptor. The study suggests an interplay among graphene‐based nanomaterials, microbiome and innate immune system.

Shedding LIGHT on the Mechanisms Underlying Severe Asthma

Posted by in categories: biotech/medical, health

Scientists have discovered that an inflammatory cytokine known as LIGHT is a major factor in the deadly airway damage that can affect people with severe asthma. This research has suggested that such airway damage could be reversed by therapeutics that halt LIGHT, and the molecule could offer a way to treat asthma. The study, which used a mouse model and human tissue, has been reported in the Journal of Allergy and Clinical Immunology.

“This is a very, very significant finding,” said senior study author and LJI Professor Michael Croft, Ph.D. “This research gives us a better understanding of the potential of therapeutic targeting of LIGHT and what we might do to relieve some of the symptoms and some of the inflammatory features seen in patients who have severe asthma.”

Immune checkpoint inhibitors: Immunotherapy for people with triple-negative breast cancer

Posted by in categories: biotech/medical, health

Immunotherapy is a type of drug that might be an option if you have triple-negative breast cancer.

Triple-negative breast cancer, also called basal-like breast cancer, is not sensitive to hormones. This means that the breast cancer cells don’t use estrogen or progesterone to grow and they don’t have hormone receptors. This type of breast cancer also doesn’t produce too much of the growth-promoting protein called HER2.

“Triple-negative breast cancer is about 10% to 15% of all breast cancer cases,” says Pooja Advani, M.D., a medical oncologist with the Robert and Monica Jacoby Center for Breast Health at Mayo Clinic in Florida.

Professor Carmit Levy from the Department of Human Genetics and Biochemistry and Dr. Yftach Gepner from the School of Public Health and the Sylvan Adams Sports Institute at TAU’s Sackler Faculty of Medicine conducted the study. Prof. Levy notes that the new research has resulted in a very important discovery by merging scientific know-how from different schools at TAU, which may help avoid metastatic cancer, Israel’s top cause of death. The study was recently published on the cover of the journal of Cancer Research.

Prof. Levy and Dr. Gepner: “Studies have demonstrated that physical exercise reduces the risk for some types of cancer by up to 35%. This positive effect is similar to the impact of exercise on other conditions, such as heart disease and diabetes. In this study we added new insight, showing that high-intensity aerobic exercise, which derives its energy from sugar, can reduce the risk of metastatic cancer by as much as 72%. If so far the general message to the public has been ‘be active, be healthy’, now we can explain how aerobic activity can maximize the prevention of the most aggressive and metastatic types of cancer.”
